Dolasetron
Dolasetron (pronounced doh-LAH-seh-tron) is a medication used primarily in the prevention of nausea and vomiting caused by chemotherapy, radiation therapy, or surgery. It belongs to a class of drugs known as 5-HT3 receptor antagonists.
Etymology
The name "Dolasetron" is derived from its chemical structure. The prefix "Dola-" is derived from the Latin word "dolere", which means "to feel pain", and "-setron" is a common suffix for 5-HT3 receptor antagonists.
Pharmacology
Dolasetron works by blocking the action of serotonin, a natural substance in the brain that can cause vomiting. It does this by binding to and blocking the 5-HT3 receptors located on the nerve cells in the brain.
Usage
Dolasetron is typically administered intravenously or orally. The dosage and frequency of use will depend on the individual's medical condition and response to treatment.
Side Effects
Common side effects of Dolasetron include headache, fatigue, constipation, and diarrhea. Serious side effects are rare, but may include irregular heartbeat, severe dizziness, and fainting.
