Aprecap

Aprecap Uses, Dosage, Side Effects, Food Interaction and all others data.

Aprecap 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. Aprecap stops substance P from binding to the NK1 receptors. By blocking the receptors, Aprecap can prevent nausea and vomiting, which often happens after chemotherapy or as a complication of surgery.

Aprecap, an antiemetic, is a substance P/neurokinin 1 (NK1) receptor antagonist which, in combination with other antiemetic agents, is indicated for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy. Aprecap is a selective high-affinity antagonist of human substance P/neurokinin 1 (NK1) receptors. Aprecap has little or no affinity for serotonin (5-HT3), dopamine, and corticosteroid receptors, the targets of existing therapies for chemotherapy-induced nausea and vomiting (CI NV).

Uses

Aprecap is used for-

- Prevention of postoperative nausea and vomiting (PONV)

- Prevention of Chemotherapy Induced Nausea and Vomiting (CINV)

Aprecap is also used to associated treatment for these conditions: Nausea and vomiting

How Aprecap works

Aprecap has been shown in animal models to inhibit emesis induced by cytotoxic chemotherapeutic agents, such as cisplatin, via central actions. Animal and human Positron Emission Tomography (PET) studies with Aprecap have shown that it crosses the blood brain barrier and occupies brain NK1 receptors. Animal and human studies show that Aprecap augments the antiemetic activity of the 5-HT3-receptor antagonist ondansetron and the corticosteroid ethasone and inhibits both the acute and delayed phases of cisplatin induced emesis.

Dosage

Aprecap dosage

Post Operative Nausea and Vomiting

The recommended oral dosage of Aprecap is 40 mg within 3 hours prior to induction of anesthesia.

Chemotherapy Induced Nausea and Vomiting

The following regimen should be used for the prevention of nausea and vomiting associated with highly emetogenic cancer chemotherapy:

Day 1: Aprecap 125mg orally, Dexamethasone 12 mg orally, 5-HT3 antagonist (Ondansetron): 24 mg 30 minutes before the start of chemotherapy.

Day 2: Aprecap 80 mg orally, Dexamethasone 8 mg orally

Day 3: Aprecap 80 mg orally, Dexamethasone 8 mg orally

Day 4: Dexamethasone 8 mg orally

*Aprecap 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. The dose of dexamethasone accounts for drug interactions.

The following regimen should be used for the prevention of nausea and vomiting associated with moderately emetogenic cancer chemotherapy:

Day 1: Aprecap 125mg orally, Dexamethasone 12 mg orally, 5-HT3 antagonist (Ondansetron): one 8 mg tablet 30 minutes before chemotherapy followed by an 8 mg dose 8 hours later.

Day 2: Aprecap 80 mg orally, 5-HT3 antagonist (Ondansetron): 8 mg tablet twice a day

Day 3: Aprecap 80 mg orally, 5-HT3 antagonist (Ondansetron): 8 mg tablet twice a day

*Aprecap 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. The dose of dexamethasone accounts for drug interactions.

Aprecap may be taken with or without food. No dosage adjustment is necessary for the elderly patients.

Patients with Renal Impairment- No dosage adjustment is necessary for patients with renal impairment or for patients with end stage renal disease (ESRD) undergoing hemodialysis.

Patients with Hepatic Impairment-No dosage adjustment is necessary for patients with mild to moderate hepatic impairment. There are no clinical data in patients with severe hepatic impairment .

Side Effects

Interaction

Aprecap is a substrate, a weak-to-moderate (dose dependent) inhibitor, and an inducer of CYP3A4. Aprecap is also an inducer of CYP2C9. Precautions should be taken while coadministering Aprecap with drugs that use CYP3A4 or CYP2C9, for example- Warfarin, Tolbutamide, Phenytoin, Ketoconazole, Itraconazole, Nefazodone, Troleandomycin, Clarithromycin, Ritonavir, Nelfinavir, Diltiazem, Rifampin, Carbamazepine etc. Upon coadministration with Aprecap, the efficacy of hormonal contraceptives during and for 28 days following the last dose of Aprecap may be reduced. Alternative or back-up methods of contraception should be used during treatment with Aprecap and for 1 month following the last dose of Aprecap.

Acute Overdose

No specific information is available on the treatment of overdosage with Aprecap. Single doses up to 600 mg of Aprecap were generally well tolerated in healthy subjects.

Because of the antiemetic activity of Aprecap, medicine-induced emesis may not be effective. Aprecap cannot be removed by hemodialysis.
