Emestop125 mg

Emestop 125 mg is indicated for- Prevention of postoperative nausea and vomiting (PONV) Prevention of Chemotherapy Induced Nausea and Vomiting (CINV)

Anti-emetic drugs

Emestop 125 mg is a selective high affinity antagonist of human substance P neurokinin 1 (NK1) receptors. When substance P attaches to these receptors, it causes nausea and vomiting. Emestop 125 mg stops substance P from binding to the NK1 receptors. By blocking the receptors, Emestop 125 mg can prevent nausea and vomiting, which often happens after chemotherapy or as a complication of surgery.

Post Operative Nausea and Vomiting: The recommended oral dosage of Emestop 125 mg is 40 mg within 3 hours prior to induction of anesthesia.

Day 2: Emestop 125 mg 80 mg orally, Dexamethasone 8 mg orally Day 3: Emestop 125 mg 80 mg orally, Dexamethasone 8 mg orally Day 4: Dexamethasone 8 mg orally Emestop 125 mg is administered orally 1 hour prior to chemotherapy treatment on Day 1 and in the morning on Days 2 and 3. Dexamethasone is administered 30 minutes prior to chemotherapy treatment on Day 1 and in the morning on Days 2 through 4.
