What should I do if I miss my dose?

  • Chemotherapy-induced nausea and vomiting (CINV)

How does aprepitant work?

Aprepitant belongs to the class of neurokinin-1 receptor antagonist medications. It works by blocking the neurotransmitter substance P in the brain. Substance P plays a role in triggering chemotherapy-induced nausea and vomiting (CINV). By preventing the signals that trigger CINV, aprepitant helps to alleviate these symptoms during treatment. The mechanism of action of aprepitant involves its selective affinity as an antagonist for neurokinin 1 (NK1) receptors. NK1 receptors are found in both the central nervous system and peripheral tissues. Aprepitant’s high affinity for NK1 receptors allows it to effectively block substance P, reducing the occurrence of nausea and vomiting associated with chemotherapy. It is important to note that aprepitant is often given as part of a combination regimen with other antiemetic agents, such as a 5-HT3 receptor antagonist and a corticosteroid like dexamethasone, to provide comprehensive protection against chemotherapy-induced nausea and vomiting.

Forms of aprepitant available

Aprepitant capsules are the most common form of aprepitant. These capsules are taken by mouth, usually once a day, with or without food. They are designed to release the medication slowly into your body, ensuring a steady level of aprepitant in your system. In some cases, aprepitant may be given to you through an intravenous (IV) infusion. This is usually done in a medical setting, such as a hospital or clinic, by a healthcare professional. The injectable form of aprepitant provides a rapid onset of action and is ideal for patients who are unable to take medications orally. Aprepitant is sometimes available in combination packs along with other medications to enhance its effectiveness. These packs may contain aprepitant, a 5-HT3 receptor antagonist (such as ondansetron), and a corticosteroid (such as dexamethasone or methylprednisolone). Using these combination packs can help provide better control of nausea and vomiting for patients undergoing chemotherapy.

Dosage of aprepitant

The dosage of aprepitant may vary depending on the specific chemotherapy regimen and individual patient factors. It is important to follow the recommended dosage instructions provided by the healthcare provider. For the prevention of chemotherapy-induced nausea and vomiting in adults, the recommended dose of aprepitant is 125 mg capsule taken orally one hour before chemotherapy, followed by 80 mg once daily in the morning for the next two days. It is usually used in combination with other antiemetic medications. In pediatric patients aged 6 months and older, the recommended dose of aprepitant for chemotherapy-induced nausea and vomiting is based on body weight.

Directions for aprepitant use

Aprepitant should be taken as directed by the healthcare provider. The specific instructions may include the timing of administration, dosage adjustments, and any necessary precautions. Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

What is the pharmacokinetics of aprepitant?

Aprepitant is a medication used to prevent nausea and vomiting associated with chemotherapy. Understanding the pharmacokinetics of a drug is essential in determining its absorption, distribution, metabolism, and elimination from the body.

  • Absorption: Aprepitant is administered orally as a capsule or a suspension. It is well absorbed in the gastrointestinal tract, with peak plasma concentrations achieved within 3 hours after oral administration
  • Distribution: Aprepitant has a high protein-binding capacity, primarily binding to plasma albumin. The volume of distribution is approximately 70 litres, indicating that it is widely distributed throughout the body
  • Metabolism: Aprepitant undergoes extensive metabolism in the liver through the cytochrome P450 enzyme system, mainly CYP3A4. It is primarily metabolized into its active metabolite, aprepitant hydrolysis product (AHP), which also exhibits antiemetic activity. Aprepitant is considered a moderate inhibitor of CYP3A4, which can affect the metabolism of other drugs that are substrates of this enzyme.
  • Elimination: The elimination half-life of aprepitant is approximately 9 to 13 hours. It is primarily excreted in the feces, with minimal renal excretion (less than 1% of the dose). Aprepitant, as well as their metabolites, undergo enterohepatic circulation, which means they are reabsorbed from the intestine and returned to the liver before being eliminated

When taken orally, aprepitant has a bioavailability of approximately 60-65%. This means that about 60-65% of the medication is absorbed into the bloodstream after oral administration. The remaining percentage is either metabolized or eliminated from the body.

Warnings, precautions and contraindications for aprepitant

  • Aprepitant may interact with certain medications, including some commonly used chemotherapy drugs, and dosage adjustments or close monitoring may be necessary
  • Common drugs that may interact with aprepitant include blood thinners like warfarin, benzodiazepines, diltiazem, antibiotics such as clarithromycin and antifungal medications such as ketoconazole and itraconazole
  • It is important to inform the healthcare provider about any existing medical conditions, allergies, and any other medications or supplements you are currently taking, to avoid potential drug interactions and adverse effects
  • Affinity for CYP3A4 enzymes may affect medication metabolism. Coadministration of aprepitant with strong CYP3A4 inducers (eg, rifampin, carbamazepine, phenytoin) may result in a substantial reduction in aprepitant plasma concentrations and decreased efficacy
  • Some individuals may be allergic to aprepitant, resulting in serious reactions. If you notice any signs of an allergic reaction such as rash, itching, swelling, dizziness, or difficulty breathing, seek immediate medical attention and discontinue the use of aprepitant until advised by a healthcare professional
  • Consult your doctor before using aprepitant during pregnancy or breastfeeding
  • The effectiveness of hormonal contraceptives may be reduced if taken at the same time as aprepitant. It is advised to use different forms of birth control

Possible side effects of aprepitant

Common side effects of aprepitant may include tiredness, hiccups, headache, dizziness, constipation, diarrhea, and changes in taste. If these side effects persist or worsen, it is important to contact a healthcare provider.

Similar drugs to aprepitant

Other medications used for the prevention of chemotherapy-induced nausea and vomiting (CINV) include ondansetron, granisetron, and palonosetron.
