Ketotifen Fumarate (Oral)
Ziten
Ketotifen Fumarate (Oral)
Indications
Asthma prophylaxis
Indication detailsView
Ketotifen is indicated in the following conditions-
- For the prophylactic treatment of bronchial asthma.
- Symptomatic treatment of allergic conditions including rhinitis and conjunctivitis.
- For alleviating the complications of itching, pain and tenderness associated with neurofibroma.
- Symptomatic treatment of allergy such as hayfever, urticaria.
Therapeutic classView
Cromoglycate & related drugs
PharmacologyView
Ketotifen has anti-allergic properties and has been used similarly, to sodium chromoglycate in the prophylactic treatment of asthma. It also has the properties of an antihistamine. Ketotifen possesses marked anti-anaphylactic properties and is effective in preventing an asthmatic attacks. Ketotifen exerts as sustained inhibitory effect on histamine reactions, which can be clearly dissociated from its anti-anaphylactic properties. Experimental investigations in asthmatic subjects have shown that Ketotifen is as effective orally as a selective mast cell stabilizer administered by inhalation. Antihistamines were ineffective in those tests. The effectiveness of Ketotifen has been studied in long-term clinical trials. Asthma attacks were reduced in number, severity and duration and in some cases, the patients were completely freed from attacks. Progressive reduction of corticosteroids and/or bronchodilators was also possible. The prophylactic activity of Ketotifen may take several weeks to become fully established. Ketotifen will not abort established attacks of asthma.
DosageView
Adults: 1 mg twice daily with food. If necessary the dose may be increased to 2 mg twice daily in severe cases.
Children above 3 years: 1 mg twice daily with food. Patients known to be easily sedated should begin treatment with 0.5 to 1 mg at night for the first few days or as directed by the physician.
Use in elderly: Same as adult dose or as advised by the physician.
Children above 3 years: 1 mg twice daily with food. Patients known to be easily sedated should begin treatment with 0.5 to 1 mg at night for the first few days or as directed by the physician.
Use in elderly: Same as adult dose or as advised by the physician.
Side effectsView
Drowsiness and in isolated cases, dry mouth and slight dizziness may occur at the beginning of treatment but usually disappear spontaneously after a few days.
ContraindicationsView
A reversible fall in the platelet count has been observed in a few patients receiving Ketotifen concomitantly with oral antidiabetic agent and it has been suggested that this combination should therefore be avoided. Although there is no evidence of any teratogenic effect, recommendations for Ketotifen in pregnancy or when breast feeding can not be given.
PrecautionsView
It is important to continue the previous treatment for a minimum of two weeks after starting Ketotifen to avoid the possibility of exacerbation of asthma. This applies specially to systemic corticosteroids and ACTH because of the possible existence of adrenocortical insufficiency in steroid dependent patient. If inter current infection occurs, Ketotifen treatment must be supplemented by specific antimicrobial therapy. During the first day of treatment with Ketotifen, reactions may be impaired and patients should be warned not to take charge of vehicle or machinery until the effect of Ketotifen treatment on the individual is known. Patients should be advised to avoid alcoholic drinks. Ketotifen may potentiate the effects of sedatives, hypnotics, antihistamines and alcohol.
InteractionsView
Ketotifen may potentiate the effects of sedatives, hypnotics, antihistamines and alcohols. A reversible fall in the platelet count has been observed in a few patients receiving Tifen concomitantly with oral antidiabetic agents and it has been suggested that this combination should therefore be avoided.
Pregnancy & lactationView
Although there is no evidence of any teratogenic effect, Ketotifen in pregnancy and lactation is not recommended.
Overdose effectsView
The reported features of overdosage include confusion, drowsiness, headache, bradycardia, respiratory depression etc. should be watched for. Elimination of the drug with gastric lavage or emessis is recommended. Otherwise, general supportive treatment is all that is required shall be instituted.
StorageView
Store in a cool and dry place, protect from light. Keep out of the reach of children.
Zithracin
Azithromycin Dihydrate
Zithracin
Azithromycin Dihydrate
Indication detailsView
Azithromycin is indicated for infections (caused by susceptible organisms) in lower respiratory tract infections including bronchitis and pneumonia, in upper respiratory tract infections including sinusitis and pharyngitis/tonsillitis, in otitis media, and in skin and soft tissue infections. In sexually transmitted diseases in men and women, Azithromycin is indicated in the treatment of non-gonococcal urethritis and cervicitis due to Chlamydia trachomatis.
PharmacologyView
Azithromycin is acid-stable and can therefore be taken orally with no need of protection from gastric acids. It is readily absorbed; its absorption is greater on an empty stomach. Time to peak concentration in adults is 2.1 to 3.2 hours for oral dosage forms. Due to the high concentration in phagocytes, azithromycin is actively transported to the site of infection. During active phagocytosis, large concentrations of azithromycin are released. The concentration of azithromycin in the tissues can be over 50 times higher than in plasma. This is due to ion trapping and the high lipid solubility.
Azithromycin's half-life allows a large single dose to be administered and yet maintain bacteriostatic levels in the infected tissue for several days. Following a single 500 mg dose, plasma concentrations of azithromycin declined in a polyphasic pattern with a mean apparent plasma clearance of 630 mL/min and a terminal elimination half life of 68 hours. The prolonged terminal half-life is thought to be due to extensive uptake and subsequent release of drug from tissues. Biliary excretion of azithromycin, predominantly unchanged, is a major route of elimination. Over the course of a week, approximately 6% of the administered dose appears as unchanged drug in urine.
Microbiology: Azithromycin acts by binding to the 50S ribosomal subunit of susceptible microorganisms and, thus, interfering with microbial protein synthesis. Nucleic acid synthesis is not affected. Azithromycin has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections:

- 500 mg as a single daily dose by the intravenous route for at least two days. Intravenous therapy should be followed by Azithromycin by the oral route at a single, daily dose of 500 mg, administered as two 250-mg tablets to complete a 7 to 10-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response.
- The recommended dose of Azithromycin for the treatment of adult patients with pelvic inflammatory disease due to the indicated organisms is: 500 mg as a single daily dose by the intravenous route for one or two days. Intravenous therapy should be followed by Azithromycin by the oral route at a single, daily dose of 250 mg to complete a 7-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response. If anaerobic microorganisms are suspected of contributing to the infection, an antimicrobial agent with anaerobic activity should be administered in combination with Azithromycin.
- Safety and effectiveness of azithromycin for injection in children or adolescents under 16 years have not been established.
AdministrationView
Reconstitution procedure of suspension-
- Step 01: Shake the bottle well to loosen the powder.
- Step 02: Add boiled and cooled water up to the water mark of the bottle label.
- Step 03: Shake until powder is completely mixed with water.
Side effectsView
Azithromycin is well tolerated with a low incidence of side effects. The side effects include nausea, vomiting, abdominal discomfort (pain/cramps), flatulence, diarrhoea, headache, dizziness, and skin rashes and are reversible upon discontinuation of therapy.
ContraindicationsView
Azithromycin is contraindicated in patients hypersensitive to Azithromycin or any other macrolide antibiotic. Co-administration of ergot derivatives and Azithromycin is contraindicated. Azithromycin is contraindicated in patients with hepatic diseases.
PrecautionsView
As with any antibiotic, observation for signs of superinfection with non-susceptible organisms, including fungi, is recommended. No dose adjustment is needed in patients with renal impairment.
InteractionsView
Azithromycin absorption is reduced in presence of food and antacid. In patients receiving ergot alkaloids Azithromycin should be avoided because of the possibility of ergotism resulting from interaction of Azithromycin with the cytochrome P-450 system. As macrolides increase the plasma concentration of digoxin and cyclosporin, caution should be exercised while co-administration. There have been no drug interactions between Azithromycin and Warfarin, Theophylline, Carbamazepine, Methylprednisolone or Cimetidine.
Pregnancy & lactationView
Pregnancy Category of Azithromycin is B. Animal reproduction studies have demonstrated that Azithromycin has no evidence of harm to the fetus. There are no adequate and well controlled studies in pregnant women. Since animal reproduction studies are not always predictive of human response, Azithromycin should be used during pregnancy only if adequate alternatives are not available. It is not known whether Azithromycin is secreted in breast milk. So, caution should be exercised when Azithromycin is administered to nursing women.
Overdose effectsView
There is no data on overdosage with Azithromycin. Typical symptoms of overdosage with macrolide antibiotics include hearing loss, severe nausea, vomiting and diarrhoea. Gastric lavage and general supportive measures are indicated.
StorageView
Keep in a dry place away from light and heat. Keep out of the reach of children.

- In typhoid fever, 500 mg (2½ teaspoonfuls) once daily for 7-10 days is given.
Azithromycin Injection (For IV Infusion only): The recommended dose of Azithromycin for injection for the treatment of adult patients with community-acquired pneumonia due to the indicated organisms is:
- 500 mg as a single daily dose by the intravenous route for at least two days. Intravenous therapy should be followed by Azithromycin by the oral route at a single, daily dose of 500 mg, administered as two 250-mg tablets to complete a 7 to 10-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response.
- The recommended dose of Azithromycin for the treatment of adult patients with pelvic inflammatory disease due to the indicated organisms is: 500 mg as a single daily dose by the intravenous route for one or two days. Intravenous therapy should be followed by Azithromycin by the oral route at a single, daily dose of 250 mg to complete a 7-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response. If anaerobic microorganisms are suspected of contributing to the infection, an antimicrobial agent with anaerobic activity should be administered in combination with Azithromycin.
- Safety and effectiveness of azithromycin for injection in children or adolescents under 16 years have not been established.
AdministrationView
Reconstitution procedure of suspension-
- Step 01: Shake the bottle well to loosen the powder.
- Step 02: Add boiled and cooled water up to the water mark of the bottle label.
- Step 03: Shake until powder is completely mixed with water.
Side effectsView
Azithromycin is well tolerated with a low incidence of side effects. The side effects include nausea, vomiting, abdominal discomfort (pain/cramps), flatulence, diarrhoea, headache, dizziness, and skin rashes and are reversible upon discontinuation of therapy.
ContraindicationsView
Azithromycin is contraindicated in patients hypersensitive to Azithromycin or any other macrolide antibiotic. Co-administration of ergot derivatives and Azithromycin is contraindicated. Azithromycin is contraindicated in patients with hepatic diseases.
PrecautionsView
As with any antibiotic, observation for signs of superinfection with non-susceptible organisms, including fungi, is recommended. No dose adjustment is needed in patients with renal impairment.
InteractionsView
Azithromycin absorption is reduced in presence of food and antacid. In patients receiving ergot alkaloids Azithromycin should be avoided because of the possibility of ergotism resulting from interaction of Azithromycin with the cytochrome P-450 system. As macrolides increase the plasma concentration of digoxin and cyclosporin, caution should be exercised while co-administration. There have been no drug interactions between Azithromycin and Warfarin, Theophylline, Carbamazepine, Methylprednisolone or Cimetidine.
Pregnancy & lactationView
Pregnancy Category of Azithromycin is B. Animal reproduction studies have demonstrated that Azithromycin has no evidence of harm to the fetus. There are no adequate and well controlled studies in pregnant women. Since animal reproduction studies are not always predictive of human response, Azithromycin should be used during pregnancy only if adequate alternatives are not available. It is not known whether Azithromycin is secreted in breast milk. So, caution should be exercised when Azithromycin is administered to nursing women.
Overdose effectsView
There is no data on overdosage with Azithromycin. Typical symptoms of overdosage with macrolide antibiotics include hearing loss, severe nausea, vomiting and diarrhoea. Gastric lavage and general supportive measures are indicated.
StorageView
Keep in a dry place away from light and heat. Keep out of the reach of children.

Indication detailsView
Azithromycin is indicated for infections (caused by susceptible organisms) in lower respiratory tract infections including bronchitis and pneumonia, in upper respiratory tract infections including sinusitis and pharyngitis/tonsillitis, in otitis media, and in skin and soft tissue infections. In sexually transmitted diseases in men and women, Azithromycin is indicated in the treatment of non-gonococcal urethritis and cervicitis due to Chlamydia trachomatis.
PharmacologyView
Azithromycin is acid-stable and can therefore be taken orally with no need of protection from gastric acids. It is readily absorbed; its absorption is greater on an empty stomach. Time to peak concentration in adults is 2.1 to 3.2 hours for oral dosage forms. Due to the high concentration in phagocytes, azithromycin is actively transported to the site of infection. During active phagocytosis, large concentrations of azithromycin are released. The concentration of azithromycin in the tissues can be over 50 times higher than in plasma. This is due to ion trapping and the high lipid solubility.
Azithromycin's half-life allows a large single dose to be administered and yet maintain bacteriostatic levels in the infected tissue for several days. Following a single 500 mg dose, plasma concentrations of azithromycin declined in a polyphasic pattern with a mean apparent plasma clearance of 630 mL/min and a terminal elimination half life of 68 hours. The prolonged terminal half-life is thought to be due to extensive uptake and subsequent release of drug from tissues. Biliary excretion of azithromycin, predominantly unchanged, is a major route of elimination. Over the course of a week, approximately 6% of the administered dose appears as unchanged drug in urine.
Microbiology: Azithromycin acts by binding to the 50S ribosomal subunit of susceptible microorganisms and, thus, interfering with microbial protein synthesis. Nucleic acid synthesis is not affected. Azithromycin has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections:

Microbiology: Azithromycin acts by binding to the 50S ribosomal subunit of susceptible microorganisms and, thus, interfering with microbial protein synthesis. Nucleic acid synthesis is not affected. Azithromycin has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections:
- Aerobic and facultative gram-positive microorganisms: Staphylococcus aureus, Streptococcus agalactiae, Streptococcus pneumoniae, Streptococcus pyogenes
- Aerobic and facultative gram-negative microorganisms: Haemophilus ducreyi, Haemophilus influenzae, Moraxella catarrhalis, Neisseria gonorrhoeae
- Other microorganisms: Chlamydia pneumoniae, Chlamydia trachomatis , Mycoplasma pneumoniae , Betalactamase production should have no effect on azithromycin activity.
- Aerobic and facultative gram-positive microorganisms: Streptococci (Groups C,F,G), Viridans group streptococci
- Aerobic and facultative gram-negative microorganisms: Bordetella pertussis, Legionella pneumophila
- Anaerobic microorganisms: Peptostreptococcus species, Prevotella bivia

Adult: 500 mg once daily orally for 3 days or 500 mg once on day 1, then 250 mg once on days 2-5 for 4 days. For sexually transmitted diseases caused by Chlamydia trachomatis in adults, the dose is 1 gm given as a single dose or 500 mg once on day 1, followed by 250 mg once daily for next 2 days may also be given.
Children:
- 10 mg/kg body weight once daily for 3 days for child over 6 months
- 200 mg (1 teaspoonful) for 3 days if body weight is 15-25 kg
- 300 mg (1½ teaspoonfuls) for 3 days if body weight is 26-35 kg; 400 mg (2 teaspoonfuls) for 3 days if body weight is 36-45 kg.
- In typhoid fever, 500 mg (2½ teaspoonfuls) once daily for 7-10 days is given.
Azithromycin Injection (For IV Infusion only): The recommended dose of Azithromycin for injection for the treatment of adult patients with community-acquired pneumonia due to the indicated organisms is:
- 500 mg as a single daily dose by the intravenous route for at least two days. Intravenous therapy should be followed by Azithromycin by the oral route at a single, daily dose of 500 mg, administered as two 250-mg tablets to complete a 7 to 10-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response.
- The recommended dose of Azithromycin for the treatment of adult patients with pelvic inflammatory disease due to the indicated organisms is: 500 mg as a single daily dose by the intravenous route for one or two days. Intravenous therapy should be followed by Azithromycin by the oral route at a single, daily dose of 250 mg to complete a 7-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response. If anaerobic microorganisms are suspected of contributing to the infection, an antimicrobial agent with anaerobic activity should be administered in combination with Azithromycin.
- Safety and effectiveness of azithromycin for injection in children or adolescents under 16 years have not been established.
AdministrationView
Reconstitution procedure of suspension-
- Step 01: Shake the bottle well to loosen the powder.
- Step 02: Add boiled and cooled water up to the water mark of the bottle label.
- Step 03: Shake until powder is completely mixed with water.
Side effectsView
Azithromycin is well tolerated with a low incidence of side effects. The side effects include nausea, vomiting, abdominal discomfort (pain/cramps), flatulence, diarrhoea, headache, dizziness, and skin rashes and are reversible upon discontinuation of therapy.
ContraindicationsView
Azithromycin is contraindicated in patients hypersensitive to Azithromycin or any other macrolide antibiotic. Co-administration of ergot derivatives and Azithromycin is contraindicated. Azithromycin is contraindicated in patients with hepatic diseases.
PrecautionsView
As with any antibiotic, observation for signs of superinfection with non-susceptible organisms, including fungi, is recommended. No dose adjustment is needed in patients with renal impairment.
InteractionsView
Azithromycin absorption is reduced in presence of food and antacid. In patients receiving ergot alkaloids Azithromycin should be avoided because of the possibility of ergotism resulting from interaction of Azithromycin with the cytochrome P-450 system. As macrolides increase the plasma concentration of digoxin and cyclosporin, caution should be exercised while co-administration. There have been no drug interactions between Azithromycin and Warfarin, Theophylline, Carbamazepine, Methylprednisolone or Cimetidine.
Pregnancy & lactationView
Pregnancy Category of Azithromycin is B. Animal reproduction studies have demonstrated that Azithromycin has no evidence of harm to the fetus. There are no adequate and well controlled studies in pregnant women. Since animal reproduction studies are not always predictive of human response, Azithromycin should be used during pregnancy only if adequate alternatives are not available. It is not known whether Azithromycin is secreted in breast milk. So, caution should be exercised when Azithromycin is administered to nursing women.
Overdose effectsView
There is no data on overdosage with Azithromycin. Typical symptoms of overdosage with macrolide antibiotics include hearing loss, severe nausea, vomiting and diarrhoea. Gastric lavage and general supportive measures are indicated.
StorageView
Keep in a dry place away from light and heat. Keep out of the reach of children.

Azithromycin Dihydrate
Indication detailsView
Azithromycin is indicated for infections (caused by susceptible organisms) in lower respiratory tract infections including bronchitis and pneumonia, in upper respiratory tract infections including sinusitis and pharyngitis/tonsillitis, in otitis media, and in skin and soft tissue infections. In sexually transmitted diseases in men and women, Azithromycin is indicated in the treatment of non-gonococcal urethritis and cervicitis due to Chlamydia trachomatis.
PharmacologyView
Azithromycin is acid-stable and can therefore be taken orally with no need of protection from gastric acids. It is readily absorbed; its absorption is greater on an empty stomach. Time to peak concentration in adults is 2.1 to 3.2 hours for oral dosage forms. Due to the high concentration in phagocytes, azithromycin is actively transported to the site of infection. During active phagocytosis, large concentrations of azithromycin are released. The concentration of azithromycin in the tissues can be over 50 times higher than in plasma. This is due to ion trapping and the high lipid solubility.
Azithromycin's half-life allows a large single dose to be administered and yet maintain bacteriostatic levels in the infected tissue for several days. Following a single 500 mg dose, plasma concentrations of azithromycin declined in a polyphasic pattern with a mean apparent plasma clearance of 630 mL/min and a terminal elimination half life of 68 hours. The prolonged terminal half-life is thought to be due to extensive uptake and subsequent release of drug from tissues. Biliary excretion of azithromycin, predominantly unchanged, is a major route of elimination. Over the course of a week, approximately 6% of the administered dose appears as unchanged drug in urine.

The prolonged terminal half-life is thought to be due to extensive uptake and subsequent release of drug from tissues. Biliary excretion of azithromycin, predominantly unchanged, is a major route of elimination. Over the course of a week, approximately 6% of the administered dose appears as unchanged drug in urine.
Microbiology: Azithromycin acts by binding to the 50S ribosomal subunit of susceptible microorganisms and, thus, interfering with microbial protein synthesis. Nucleic acid synthesis is not affected. Azithromycin has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections:

DosageView
Oral-
Adult: 500 mg once daily orally for 3 days or 500 mg once on day 1, then 250 mg once on days 2-5 for 4 days. For sexually transmitted diseases caused by Chlamydia trachomatis in adults, the dose is 1 gm given as a single dose or 500 mg once on day 1, followed by 250 mg once daily for next 2 days may also be given.
Children:
Azithromycin Injection (For IV Infusion only): The recommended dose of Azithromycin for injection for the treatment of adult patients with community-acquired pneumonia due to the indicated organisms is:
Adult: 500 mg once daily orally for 3 days or 500 mg once on day 1, then 250 mg once on days 2-5 for 4 days. For sexually transmitted diseases caused by Chlamydia trachomatis in adults, the dose is 1 gm given as a single dose or 500 mg once on day 1, followed by 250 mg once daily for next 2 days may also be given.
Children:
- 10 mg/kg body weight once daily for 3 days for child over 6 months
- 200 mg (1 teaspoonful) for 3 days if body weight is 15-25 kg
- 300 mg (1½ teaspoonfuls) for 3 days if body weight is 26-35 kg; 400 mg (2 teaspoonfuls) for 3 days if body weight is 36-45 kg.
- In typhoid fever, 500 mg (2½ teaspoonfuls) once daily for 7-10 days is given.
Azithromycin Injection (For IV Infusion only): The recommended dose of Azithromycin for injection for the treatment of adult patients with community-acquired pneumonia due to the indicated organisms is:
- 500 mg as a single daily dose by the intravenous route for at least two days. Intravenous therapy should be followed by Azithromycin by the oral route at a single, daily dose of 500 mg, administered as two 250-mg tablets to complete a 7 to 10-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response.
- The recommended dose of Azithromycin for the treatment of adult patients with pelvic inflammatory disease due to the indicated organisms is: 500 mg as a single daily dose by the intravenous route for one or two days. Intravenous therapy should be followed by Azithromycin by the oral route at a single, daily dose of 250 mg to complete a 7-day course of therapy. The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response. If anaerobic microorganisms are suspected of contributing to the infection, an antimicrobial agent with anaerobic activity should be administered in combination with Azithromycin.
- Safety and effectiveness of azithromycin for injection in children or adolescents under 16 years have not been established.
AdministrationView
Reconstitution procedure of suspension-
- Step 01: Shake the bottle well to loosen the powder.
- Step 02: Add boiled and cooled water up to the water mark of the bottle label.
- Step 03: Shake until powder is completely mixed with water.
Side effectsView
Azithromycin is well tolerated with a low incidence of side effects. The side effects include nausea, vomiting, abdominal discomfort (pain/cramps), flatulence, diarrhoea, headache, dizziness, and skin rashes and are reversible upon discontinuation of therapy.
ContraindicationsView
Azithromycin is contraindicated in patients hypersensitive to Azithromycin or any other macrolide antibiotic. Co-administration of ergot derivatives and Azithromycin is contraindicated. Azithromycin is contraindicated in patients with hepatic diseases.
PrecautionsView
As with any antibiotic, observation for signs of superinfection with non-susceptible organisms, including fungi, is recommended. No dose adjustment is needed in patients with renal impairment.
InteractionsView
Azithromycin absorption is reduced in presence of food and antacid. In patients receiving ergot alkaloids Azithromycin should be avoided because of the possibility of ergotism resulting from interaction of Azithromycin with the cytochrome P-450 system. As macrolides increase the plasma concentration of digoxin and cyclosporin, caution should be exercised while co-administration. There have been no drug interactions between Azithromycin and Warfarin, Theophylline, Carbamazepine, Methylprednisolone or Cimetidine.
Pregnancy & lactationView
Pregnancy Category of Azithromycin is B. Animal reproduction studies have demonstrated that Azithromycin has no evidence of harm to the fetus. There are no adequate and well controlled studies in pregnant women. Since animal reproduction studies are not always predictive of human response, Azithromycin should be used during pregnancy only if adequate alternatives are not available. It is not known whether Azithromycin is secreted in breast milk. So, caution should be exercised when Azithromycin is administered to nursing women.
Overdose effectsView
There is no data on overdosage with Azithromycin. Typical symptoms of overdosage with macrolide antibiotics include hearing loss, severe nausea, vomiting and diarrhoea. Gastric lavage and general supportive measures are indicated.
StorageView
Keep in a dry place away from light and heat. Keep out of the reach of children.

Azithromycin Dihydrate
Indication detailsView
Azithromycin is indicated for infections (caused by susceptible organisms) in lower respiratory tract infections including bronchitis and pneumonia, in upper respiratory tract infections including sinusitis and pharyngitis/tonsillitis, in otitis media, and in skin and soft tissue infections. In sexually transmitted diseases in men and women, Azithromycin is indicated in the treatment of non-gonococcal urethritis and cervicitis due to Chlamydia trachomatis.
PharmacologyView
Azithromycin is acid-stable and can therefore be taken orally with no need of protection from gastric acids. It is readily absorbed; its absorption is greater on an empty stomach. Time to peak concentration in adults is 2.1 to 3.2 hours for oral dosage forms. Due to the high concentration in phagocytes, azithromycin is actively transported to the site of infection. During active phagocytosis, large concentrations of azithromycin are released. The concentration of azithromycin in the tissues can be over 50 times higher than in plasma. This is due to ion trapping and the high lipid solubility.
Azithromycin's half-life allows a large single dose to be administered and yet maintain bacteriostatic levels in the infected tissue for several days. Following a single 500 mg dose, plasma concentrations of azithromycin declined in a polyphasic pattern with a mean apparent plasma clearance of 630 mL/min and a terminal elimination half life of 68 hours.

Ziton
Zinc Sulfate Monohydrate
Indications
Zinc deficiency
Indication detailsView
Zinc Sulfate Monohydrate is indicated in zinc deficiency and/or zinc losing conditions. Zinc deficiency can occur as a result of inadequate diet or malabsorption. Excessive loss of zinc can occur in trauma, burns, diarrhoea and protein losing conditions. A zinc supplement is given until clinical improvement occurs but it may need to be continued in severe malabsorption, metabolic disease or in zinc losing states.
Therapeutic classView
Specific mineral preparations
PharmacologyView
Zinc sulphate monohydrate is an essential trace element and is involved in a number of body enzyme systems. The body needs zinc for normal growth and health. Zinc is also vital for sexual maturation and reproduction, dark vision adaptation, olfactory and gustatory activity, insulin storage & release and for a variety of host immune defenses. Zinc deficiency may lead to impaired immune function, delayed wound healing, a decrease in sense of taste and smell, a reduced ability to fight infections, poor night vision, increased risk of abortion, alopecia, mental lethargy, skin changes and poor development of reproductive organs.
DosageView
Child under 10 kg: 5 ml (1 teaspoonful) 2 times daily after food.
Child between 10-30 kg: 10 ml (2 teaspoonfuls) 1-3 times daily after food.
Adults and child over 30 kg: 20 ml (4 teaspoonfuls) 1-3 times daily after food.
This drug is most effective if they are taken at least 1 hour before or 2 hour after meals. However, if causes stomach upset, this may be taken with a meal.
Child between 10-30 kg: 10 ml (2 teaspoonfuls) 1-3 times daily after food.
Adults and child over 30 kg: 20 ml (4 teaspoonfuls) 1-3 times daily after food.

AdministrationView
For dispersible tablet-
- Place the tablet in a teaspoon
- Add adequate amount of water
- Let the tablet dissolve completely
- Give the entire spoonful solution
Side effectsView
Zinc may cause nausea, vomiting, diarrhoea, stomach upset, heartburn and gastritis.
ContraindicationsView
It is contraindicated in those who are hypersensitive to any component of the ingredient of this preparation.
PrecautionsView
In acute renal failure, zinc accumulation may occur in body; so dose adjustment is needed.
InteractionsView
Concomitant intake of a tetracycline and zinc may decrease the absorption of both the tetracycline and zinc. Similarly concomitant administration of zinc and quinolone drug may also decrease the absorption of both. Concomitant intake of penicillamine and zinc may decrese absorption of zinc.
Pregnancy & lactationView
The safety of this product in human pregnancy has not been established. Zinc crosses the placenta and is present in breast milk.

The timing of the switch to oral therapy should be done at the discretion of the physician and in accordance with clinical response. If anaerobic microorganisms are suspected of contributing to the infection, an antimicrobial agent with anaerobic activity should be administered in combination with Azithromycin.
- Safety and effectiveness of azithromycin for injection in children or adolescents under 16 years have not been established.
AdministrationView
Reconstitution procedure of suspension-
- Step 01: Shake the bottle well to loosen the powder.
- Step 02: Add boiled and cooled water up to the water mark of the bottle label.
- Step 03: Shake until powder is completely mixed with water.
Side effectsView
Azithromycin is well tolerated with a low incidence of side effects. The side effects include nausea, vomiting, abdominal discomfort (pain/cramps), flatulence, diarrhoea, headache, dizziness, and skin rashes and are reversible upon discontinuation of therapy.
ContraindicationsView
Azithromycin is contraindicated in patients hypersensitive to Azithromycin or any other macrolide antibiotic. Co-administration of ergot derivatives and Azithromycin is contraindicated. Azithromycin is contraindicated in patients with hepatic diseases.
PrecautionsView
As with any antibiotic, observation for signs of superinfection with non-susceptible organisms, including fungi, is recommended. No dose adjustment is needed in patients with renal impairment.
InteractionsView
Azithromycin absorption is reduced in presence of food and antacid. In patients receiving ergot alkaloids Azithromycin should be avoided because of the possibility of ergotism resulting from interaction of Azithromycin with the cytochrome P-450 system. As macrolides increase the plasma concentration of digoxin and cyclosporin, caution should be exercised while co-administration. There have been no drug interactions between Azithromycin and Warfarin, Theophylline, Carbamazepine, Methylprednisolone or Cimetidine.
Pregnancy & lactationView
Pregnancy Category of Azithromycin is B. Animal reproduction studies have demonstrated that Azithromycin has no evidence of harm to the fetus. There are no adequate and well controlled studies in pregnant women. Since animal reproduction studies are not always predictive of human response, Azithromycin should be used during pregnancy only if adequate alternatives are not available. It is not known whether Azithromycin is secreted in breast milk. So, caution should be exercised when Azithromycin is administered to nursing women.
Overdose effectsView
There is no data on overdosage with Azithromycin. Typical symptoms of overdosage with macrolide antibiotics include hearing loss, severe nausea, vomiting and diarrhoea. Gastric lavage and general supportive measures are indicated.
StorageView
Keep in a dry place away from light and heat. Keep out of the reach of children.

Azithromycin Dihydrate
Indication detailsView
Azithromycin is indicated for infections (caused by susceptible organisms) in lower respiratory tract infections including bronchitis and pneumonia, in upper respiratory tract infections including sinusitis and pharyngitis/tonsillitis, in otitis media, and in skin and soft tissue infections. In sexually transmitted diseases in men and women, Azithromycin is indicated in the treatment of non-gonococcal urethritis and cervicitis due to Chlamydia trachomatis.
PharmacologyView
Azithromycin is acid-stable and can therefore be taken orally with no need of protection from gastric acids. It is readily absorbed; its absorption is greater on an empty stomach. Time to peak concentration in adults is 2.1 to 3.2 hours for oral dosage forms. Due to the high concentration in phagocytes, azithromycin is actively transported to the site of infection. During active phagocytosis, large concentrations of azithromycin are released. The concentration of azithromycin in the tissues can be over 50 times higher than in plasma. This is due to ion trapping and the high lipid solubility.
Azithromycin's half-life allows a large single dose to be administered and yet maintain bacteriostatic levels in the infected tissue for several days. Following a single 500 mg dose, plasma concentrations of azithromycin declined in a polyphasic pattern with a mean apparent plasma clearance of 630 mL/min and a terminal elimination half life of 68 hours. The prolonged terminal half-life is thought to be due to extensive uptake and subsequent release of drug from tissues. Biliary excretion of azithromycin, predominantly unchanged, is a major route of elimination. Over the course of a week, approximately 6% of the administered dose appears as unchanged drug in urine.
Microbiology: Azithromycin acts by binding to the 50S ribosomal subunit of susceptible microorganisms and, thus, interfering with microbial protein synthesis. Nucleic acid synthesis is not affected. Azithromycin has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections:

Therapeutic classView
Third generation Cephalosporins
PharmacologyView
Ceftazidime is a semisynthetic, broad-spectrum, beta-lactam antibiotic for parenteral administration. Ceftazidime is bactericidal in action exerting its effect by inhibition of enzymes responsible for cell-wall synthesis. A wide range of gram-negative organisms is susceptible to ceftazidime in vitro, including strains resistant to gentamicin and other aminoglycosides. In addition, ceftazidime has been shown to be active against gram-positive organisms. It is highly stable to most clinically important beta-lactamases, plasmid or chromosomal, which are produced by both gram-negative and gram-positive organisms and, consequently, is active against many strains resistant to ampicillin and other cephalosporins.
DosageView
The usual adult dosage is 1 gram administered intravenously or intramuscularly every 8 to 12 hours. The dosage and route should be determined by the susceptibility of the causative organisms, the severity of infection and the condition, and renal function of the patient.
Ceftazidime is to be used by the parenteral route, the dosage depending upon the severity, sensitivity & type of infections and the age, weight & renal function of the patient.
Adults: The adult dosage range for ceftazidime is 1 to 6 gm per day 8 or 12 hourly (IM/IV) in the majority of infections, 1 gm 8 hourly or 2 gm 12 hourly should be given.
Neonates and Children up to 2 months of age: The usual dosage range is 25 to 60 mg/kg/day as two divided doses.

Adults: The adult dosage range for ceftazidime is 1 to 6 gm per day 8 or 12 hourly (IM/IV) in the majority of infections, 1 gm 8 hourly or 2 gm 12 hourly should be given.
- In urinary tract infections and many less serious infections: 500 mg or 1 gm 12 hourly is usually adequate.
- In severe infections, especially immunocompromised patients, including those with neutropenia: 2 gm 8 or 12 hourly should be administered. When used as a prophylactic agent in prostatic surgery 1 gm should be given at the induction of anesthesia. A second dose should be considered at the time of catheter removal.
- Cystic fibrosis: In fibrocystic adults with normal renal function who have pseudomonal lung infections, high doses of 100 to 150 mg/kg/day as three divided doses should be used.
Neonates and Children up to 2 months of age: The usual dosage range is 25 to 60 mg/kg/day as two divided doses.
AdministrationView
Ceftazidime may be given intravenously or by deep IM injection into a large muscle mass such as the upper outer quadrant of the gluteus maximus or lateral proof of the thigh. Intra-arterial administration should be avoided. For IV/IM administration, Ceftazidime should be reconstituted with the supplied Sterile Water for Injection.
Side effectsView
The most common side-effects are local reactions following IV injection and allergic and gastrointestinal reactions. Hypersensitivity reactions are pruritus, rash, and fever. Angioedema and anaphylaxis have been reported very rarely. Gastrointestinal symptoms are diarrhea, nausea, vomiting, and abdominal pain. Central nervous system reactions included headache, dizziness, and paresthesia.
ContraindicationsView
Ceftazidime is contraindicated in patients who have shown hypersensitivity to Ceftazidime or the cephalosporin group of antibiotics.
PrecautionsView
The total daily dosage should be reduced when Ceftazidime is administered to patients with renal insufficiency. Ceftazidime should be prescribed with caution in individuals with a history of gastrointestinal disease, particularly colitis.
Pregnancy & lactationView
Pregnancy: No adequate and well-controlled studies in pregnant women have been conducted with Ceftazidime. Because animal reproduction studies are not always predictive of human response this drug should be used during pregnancy only if clearly needed.
Lactation: Ceftazidime is excreted in human milk in low concentrations. Because many drugs are excreted in human milk and because the safety of the component of the injections in nursing infants has not been established, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric usageView
Impaired Renal Function: Ceftazidime is excreted by the kidneys, almost exclusively by glomerular filtration. Therefore, in patients with impaired renal function (glomerular filtration rate <50 mL/min), it is recommended that the dosage of ceftazidime be reduced to compensate for its slower excretion. In patients with suspected renal insufficiency, an initial loading dose of 1 gram of Ceftazidime may be given. An estimate of GFR should be made to determine the appropriate maintenance dosage.
Dosage in peritoneal dialysis: Ceftazidime may also be used in peritoneal dialysis and continuous ambulatory peritoneal dialysis (CAPD). As well as using Ceftazidime intravenously, it can be incorporated into the dialysis fluid (usually 125 to 250 mg for 2L of dialysis fluid).
Impaired Hepatic Function: No adjustment in dosage is required for patients with hepatic dysfunction.
