Anti-emetic drugs

Palonosetron is a 5-HT3 receptor antagonist with a strong binding affinity for this receptor and little or no affinity for other receptors. It is thought that chemotherapeutic agents produce nausea and vomiting by releasing serotonin from the enterochromaffin cells of the small intestine and that the released serotonin then activates 5-HT3 receptors that are located on the nerve terminals of the vagus in the periphery and centrally in the chemoreceptor trigger zone of the area postrema, to initiate the vomiting reflex. Postoperative nausea and vomiting is influenced by multiple patient, surgical and anesthesia related factorcs and is triggered by release of 5-HT3 in a cascade of neuronal event involving both the central nervous system and the gastrointestinal tract. The 5-HT3 receptor has been demonstrated to selectively participate in the emetic response. Palonosetron works by blocking the actions of Serotonin, associated with nausea and vomiting, at 5-HTs receptor. It is likely that Palonosetron works in the small intestine but it may also work in the brain.

Pharmacokinetics: Palonosetron exhibits linear dose-proportional pharmacokinetics over the doserange 1-90 pg/kg in healthy subjects and in patients with cancer. In cancer patients receiving single intravenous doses of Palonosetron in this dose range, the mean maximum plasma concentration (Cmax) ranges from 0.89 to 336 ng/ml and the area under the plasma concentration-time curve from zero to infinity (AUCo-co) ranges from 13.8 to 957 ng.h/ml. Palonosetron has a volume of distribution of approximately 6.9-7.9 L/kg, with approximately 62% bound to plasma proteins. Approximately 50% of Palonosetron is metabolized into two inactive metabolites that exhibit <1% of the 5-HT3 receptor antagonist activity. Approximately 40% of the drug is metabolised via kidney, 50% by liver CYP2D6 (mainly), CYP3A4 and CYP1A2 isoenzymes. About 50% of the drug goes under metabolism. After a single intravenous dose, approximately 40% is excreted as unchanged drug in the urine after 144 hours. Total body clearance of Palonosetron is 160±35 ml/h/kg, and renal clearance is 66.5±18.2 ml/h/kg in healthy subjects. Palonosetron exhibits a longer half-life (40 hours) and has a greater 5-HT3 receptor binding affinity.

Usual dosage: Adult tablet dosage: 0.5 mg daily. Adult IV dosage: A single IV dose of 0.075 mg should be administered over 10 seconds.

Chemotherapy-induced nausea and vomiting: Adult tablet dosage: 0.5 mg administered approximately 1 hour prior to the start of chemotherapy. Adult IV dosage: A single IV dose of 0.25 mg should be administered over 30 seconds approximately 30 minutes before the start of chemotherapy.

Radiotherapy-induced nausea and vomiting: A single IV dose of 0.25 mg should be administered over 30 seconds approximately 30 minutes before each week of radiation fraction.

Post-operative nausea and vomiting: A single IV dose of 0.075 mg should be administered over 10 seconds immediately before induction of anesthesia.

Children dosage: (1 month to 17 years): A single IV dose at 20 mcg/kg body weight. Which maximum dose is 1.5 mg.

The most common adverse reactions are headaches and constipation.

Palonosetron is contraindicated in patients known to have hypersensitivity to the drug or any of its components.

In controlled clinical trials, Palonosetron injection has been safely administered with corticosteroids, analgesics, antiemetics/antinauseants, antispasmodics and anticholinergic agents. Palonosetron did not inhibit the antitumor activity of cisplatin, cyclophosphamide, cytarabine, doxorubicin and mitomycin C in murine tumor models. Concomitant administration of Palonosetron and metoclopramide has no significant pharmacokinetic interactions. In vitro studies indicated that palonosetron is not inhibitor of CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2D6, CYP2E1 & CYP3A4/5 (CYP2C19 was not investigated) nor does it induce the activity of CYP1A2, CYP2D6 or CYP3A4/5. Therefore, the potential for clinically significant drug interactions with Palonosetron appears to be low.

Pregnancy category 'B'. It is not known whether Palonosetron is excreted in breast milk.

Use in elderly patients: No dosage adjustment is recommended in elderly patients >65 years of age.

Use in Children: (1 month to 10 years): A single IV dose at 20 mcg/kg body weight. Which maximum dose is 1.5 mg.

Use in patients with impaired renal and hepatic function: No dosage adjustment is recommended in patients with renal and hepatic dysfunction.

There is no known antidote to Palonosetron. Overdose should be managed with supportive care.

Selexipag is indicated for the treatment of pulmonary arterial hypertension (PAH, WHO Group I) to delay disease progression and reduce the risk of hospitalization for PAH.

Non-prostanoid IP prostacyclin receptor agonist

Selexipag is a selective non-prostanoid IP prostacyclin receptor agonist. Selexipag is a pale yellow crystalline powder that is practically insoluble in water. In the solid-state selexipag is very stable, is not hygroscopic, and is not light sensitive. Selexipag is an oral prostacyclin receptor (IP receptor) agonist that is structurally distinct from prostacyclin. Selexipag is hydrolyzed by carboxylesterase 1 to yield its active metabolite, which is approximately 37-fold as potent as selexipag. Selexipag and the active metabolite are selective for the IP receptor versus other prostanoid receptors (EP1-4, DP, FP, and TP).

The recommended starting dose is 200 mcg twice daily. Tolerability may be improved when taken with food. Increase the dose by 200 mcg twice daily at weekly intervals to the highest tolerated dose up to 1600 mcg twice daily. The maintenance dose is determined by tolerability.

Pediatric use: Safety and effectiveness in pediatric patients have not been established.

Geriatric use: No overall differences have been observed.

Hepatic impairment: For Moderate hepatic impairment patients starting dose is 200 mcg once daily, increase the dose by 200 mcg once daily at weekly intervals to the highest tolerated dose up to 1600 mcg. Avoid use of Selexipag in patients with severe hepatic impairment (Child-Pugh class C).

The most common side-effects of selexipag are Nausea, Diarrhoea, Vomiting, Headache, Jaw pain, muscle pain, low appetite and low RBC count.

Discontinue Selexipag if the patient develops the sign and symptoms of Pulmonary Veno-Occlusive Disease (PVOD)

Moderate CYP2C8 inhibitors (e.g., deferasirox and teriflunomide) may increase exposure to the active metabolite of Selexipag: CYP2C8 inducers (e.g., rifampicin) decrease exposure to the active metabolite & Increase concentration up to twice the dose of Selexipag

There are no adequate and well controlled studies with Selexipag in pregnant women It is not known if Selexipag is present in human milk. Selexipag or breastfeeding should be discontinued in nursing mother.

Isolated cases of overdose up to 3200 mcg were reported. Mild transient nausea was the only reported consequence. In the event of overdose, supportive measures must be taken as required.

Keep in a dry place away from light and heat. Keep out of reach of children.

Anti-emetic drugs

Palonosetron is a 5-HT3 receptor antagonist with a strong binding affinity for this receptor and little or no affinity for other receptors. It is thought that chemotherapeutic agents produce nausea and vomiting by releasing serotonin from the enterochromaffin cells of the small intestine and that the released serotonin then activates 5-HT3 receptors that are located on the nerve terminals of the vagus in the periphery and centrally in the chemoreceptor trigger zone of the area postrema, to initiate the vomiting reflex. Postoperative nausea and vomiting is influenced by multiple patient, surgical and anesthesia related factorcs and is triggered by release of 5-HT3 in a cascade of neuronal event involving both the central nervous system and the gastrointestinal tract. The 5-HT3 receptor has been demonstrated to selectively participate in the emetic response. Palonosetron works by blocking the actions of Serotonin, associated with nausea and vomiting, at 5-HTs receptor. It is likely that Palonosetron works in the small intestine but it may also work in the brain.

Pharmacokinetics: Palonosetron exhibits linear dose-proportional pharmacokinetics over the doserange 1-90 pg/kg in healthy subjects and in patients with cancer. In cancer patients receiving single intravenous doses of Palonosetron in this dose range, the mean maximum plasma concentration (Cmax) ranges from 0.89 to 336 ng/ml and the area under the plasma concentration-time curve from zero to infinity (AUCo-co) ranges from 13.8 to 957 ng.h/ml. Palonosetron has a volume of distribution of approximately 6.9-7.9 L/kg, with approximately 62% bound to plasma proteins. Approximately 50% of Palonosetron is metabolized into two inactive metabolites that exhibit <1% of the 5-HT3 receptor antagonist activity. Approximately 40% of the drug is metabolised via kidney, 50% by liver CYP2D6 (mainly), CYP3A4 and CYP1A2 isoenzymes. About 50% of the drug goes under metabolism. After a single intravenous dose, approximately 40% is excreted as unchanged drug in the urine after 144 hours. Total body clearance of Palonosetron is 160±35 ml/h/kg, and renal clearance is 66.5±18.2 ml/h/kg in healthy subjects. Palonosetron exhibits a longer half-life (40 hours) and has a greater 5-HT3 receptor binding affinity.

Usual dosage: Adult tablet dosage: 0.5 mg daily. Adult IV dosage: A single IV dose of 0.075 mg should be administered over 10 seconds.

Chemotherapy-induced nausea and vomiting: Adult tablet dosage: 0.5 mg administered approximately 1 hour prior to the start of chemotherapy. Adult IV dosage: A single IV dose of 0.25 mg should be administered over 30 seconds approximately 30 minutes before the start of chemotherapy.

Radiotherapy-induced nausea and vomiting: A single IV dose of 0.25 mg should be administered over 30 seconds approximately 30 minutes before each week of radiation fraction.

Post-operative nausea and vomiting: A single IV dose of 0.075 mg should be administered over 10 seconds immediately before induction of anesthesia.

Children dosage: (1 month to 17 years): A single IV dose at 20 mcg/kg body weight. Which maximum dose is 1.5 mg.

The most common adverse reactions are headaches and constipation.

Palonosetron is contraindicated in patients known to have hypersensitivity to the drug or any of its components.

In controlled clinical trials, Palonosetron injection has been safely administered with corticosteroids, analgesics, antiemetics/antinauseants, antispasmodics and anticholinergic agents. Palonosetron did not inhibit the antitumor activity of cisplatin, cyclophosphamide, cytarabine, doxorubicin and mitomycin C in murine tumor models.

Chemotherapy-induced nausea and vomiting: Adult tablet dosage: 0.5 mg administered approximately 1 hour prior to the start of chemotherapy. Adult IV dosage: A single IV dose of 0.25 mg should be administered over 30 seconds approximately 30 minutes before the start of chemotherapy.

Radiotherapy-induced nausea and vomiting: A single IV dose of 0.25 mg should be administered over 30 seconds approximately 30 minutes before each week of radiation fraction.

Post-operative nausea and vomiting: A single IV dose of 0.075 mg should be administered over 10 seconds immediately before induction of anesthesia.

Children dosage: (1 month to 17 years): A single IV dose at 20 mcg/kg body weight. Which maximum dose is 1.5 mg.

The most common adverse reactions are headaches and constipation.

Palonosetron is contraindicated in patients known to have hypersensitivity to the drug or any of its components.

In controlled clinical trials, Palonosetron injection has been safely administered with corticosteroids, analgesics, antiemetics/antinauseants, antispasmodics and anticholinergic agents. Palonosetron did not inhibit the antitumor activity of cisplatin, cyclophosphamide, cytarabine, doxorubicin and mitomycin C in murine tumor models. Concomitant administration of Palonosetron and metoclopramide has no significant pharmacokinetic interactions. In vitro studies indicated that palonosetron is not inhibitor of CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2D6, CYP2E1 & CYP3A4/5 (CYP2C19 was not investigated) nor does it induce the activity of CYP1A2, CYP2D6 or CYP3A4/5. Therefore, the potential for clinically significant drug interactions with Palonosetron appears to be low.

Pregnancy category 'B'. It is not known whether Palonosetron is excreted in breast milk.

Use in elderly patients: No dosage adjustment is recommended in elderly patients >65 years of age.

Use in Children: (1 month to 10 years): A single IV dose at 20 mcg/kg body weight. Which maximum dose is 1.5 mg.

Anti-emetic drugs

Palonosetron is a 5-HT3 receptor antagonist with a strong binding affinity for this receptor and little or no affinity for other receptors. It is thought that chemotherapeutic agents produce nausea and vomiting by releasing serotonin from the enterochromaffin cells of the small intestine and that the released serotonin then activates 5-HT3 receptors that are located on the nerve terminals of the vagus in the periphery and centrally in the chemoreceptor trigger zone of the area postrema, to initiate the vomiting reflex. Postoperative nausea and vomiting is influenced by multiple patient, surgical and anesthesia related factorcs and is triggered by release of 5-HT3 in a cascade of neuronal event involving both the central nervous system and the gastrointestinal tract. The 5-HT3 receptor has been demonstrated to selectively participate in the emetic response. Palonosetron works by blocking the actions of Serotonin, associated with nausea and vomiting, at 5-HTs receptor. It is likely that Palonosetron works in the small intestine but it may also work in the brain.

Pharmacokinetics: Palonosetron exhibits linear dose-proportional pharmacokinetics over the doserange 1-90 pg/kg in healthy subjects and in patients with cancer. In cancer patients receiving single intravenous doses of Palonosetron in this dose range, the mean maximum plasma concentration (Cmax) ranges from 0.89 to 336 ng/ml and the area under the plasma concentration-time curve from zero to infinity (AUCo-co) ranges from 13.8 to 957 ng.h/ml. Palonosetron has a volume of distribution of approximately 6.9-7.9 L/kg, with approximately 62% bound to plasma proteins. Approximately 50% of Palonosetron is metabolized into two inactive metabolites that exhibit <1% of the 5-HT3 receptor antagonist activity. Approximately 40% of the drug is metabolised via kidney, 50% by liver CYP2D6 (mainly), CYP3A4 and CYP1A2 isoenzymes. About 50% of the drug goes under metabolism. After a single intravenous dose, approximately 40% is excreted as unchanged drug in the urine after 144 hours. Total body clearance of Palonosetron is 160±35 ml/h/kg, and renal clearance is 66.5±18.2 ml/h/kg in healthy subjects. Palonosetron exhibits a longer half-life (40 hours) and has a greater 5-HT3 receptor binding affinity.
