Aprepitant
About Aprepitant
Aprepitant belongs to a class of drugs called anti-emetics. It is used in combination with other medicines to prevent nausea and vomiting caused by chemotherapy (anti-cancer medicines) in adults and adolescents aged 12 years and above. Nausea is a feeling of uneasiness in the stomach that often comes before vomiting. On the other hand, vomiting is the forcible voluntary or involuntary emptying of stomach contents through the mouth.
Aprepitant contains Aprepitant, a neurokinin 1 (NK1) receptor antagonist which works by blocking the neurokinin-1 receptor (causes the feeling of sickness) present in the vomiting centre in the brain. Thus, it helps prevent nausea and vomiting.
Take Aprepitant as prescribed. You are recommended to take Aprepitant for as long as your doctor has advised it. In some cases, Aprepitant may cause common side effects such as headache, constipation, loss of appetite, tiredness, indigestion, and hiccups. Most of these side effects do not require medical attention and gradually resolve over time. However, consult your doctor immediately if the side effects persist or worsen.

If you are pregnant or breastfeeding, please inform your doctor before taking Aprepitant. Avoid driving or operating machinery if you feel dizzy or sleepy after taking Aprepitant.

Patients Concern
Disease/Condition Glossary
Nausea and vomiting: Nausea is an uneasiness in the stomach that usually precedes vomiting. Vomiting, on the other hand, is a normal bodily response in which a person desires to evacuate stomach contents from the mouth aggressively. In brief, nausea and vomiting are symptoms of a variety of disorders, including infections, motion sickness, an early stage of pregnancy, and gastroparesis (slow stomach emptying). Vomiting is controlled by a receptor in the brain known as the chemoreceptor trigger zone (CTZ). After chemotherapy and radiation therapy, nausea and vomiting are common side effects. It can also arise as a side effect of an operation or surgery. Controlling vomiting and nausea in cancer patients is critical for conducting daily tasks. It can cause mental abnormalities, lack of appetite, malnutrition, and dehydration if not managed.
