GRANISETRON

GRANISETRON: Granisetron is a medication used to prevent nausea and vomiting caused by chemotherapy or radiation therapy. It belongs to a class of drugs known as selective serotonin 5-HT3 receptor antagonists.

The drug works by blocking the action of serotonin, a neurotransmitter in the brain that is responsible for triggering feelings of nausea and vomiting. By inhibiting the binding of serotonin to its receptors in the gut and brain, granisetron helps to prevent these unpleasant symptoms.

Granisetron is available in various forms, including tablets, oral solution, and injection. The recommended dose and route of administration may vary depending on the specific situation and the individual’s response. Generally, it is taken orally as a tablet or liquid about 1 hour before chemotherapy or radiation treatment. In some cases, healthcare professionals may administer it intravenously.

Side effects of granisetron are generally mild and temporary. Common side effects may include headache, constipation, diarrhea, dizziness, and fatigue. Infrequently, there may be allergic reactions such as rash, itching, swelling, or difficulty breathing. While rare, it is possible to experience serious side effects such as irregular heartbeat or changes in liver function. It is important to consult a healthcare professional if any concerning side effects occur.

Overall, granisetron is an effective medication for managing chemotherapy or radiation-induced nausea and vomiting. It is commonly used in clinical practice to improve the quality of life for cancer patients undergoing these treatments.
