Patients receiving chemotherapy or radiation treatment find great relief from the effective drug aprecap aprepitant capsule. The active component, aprepitant, is a member of a group of drugs known as neurokinin receptor antagonists that are especially designed to treat the difficult side effects of chemotherapy-induced nausea and vomiting (CINV), which frequently accompany cancer treatments. Aprecap Aprepitant Capsule successfully prevents and controls these upsetting side effects by inhibiting substance P, a neurotransmitter in the brain that initiates impulses that cause nausea and vomiting.
