Avodart is a brand name for the medication dutasteride, which is a prescription drug used primarily to treat benign prostatic hyperplasia (BPH), also known as an enlarged prostate gland, in men. It belongs to a class of medications known as 5-alpha-reductase inhibitors.
Here are some key points about Avodart (dutasteride):

Treatment of BPH: Avodart is used to improve symptoms of BPH, such as difficulty urinating, weak urine flow, and the need to urinate frequently or urgently.
Mechanism of Action: Dutasteride works by inhibiting the activity of the enzyme 5-alpha-reductase, which is responsible for converting testosterone to dihydrotestosterone (DHT). By reducing DHT levels, Avodart helps to shrink the enlarged prostate gland, relieving symptoms of BPH.
Dosage: Avodart is typically taken orally in the form of capsules. The usual recommended dose is one capsule (0.5 mg) taken once daily. It may take several weeks to months of treatment before noticeable improvement in symptoms occurs.
Side Effects: Common side effects of Avodart may include decreased libido, erectile dysfunction, decreased ejaculate volume, breast tenderness or enlargement, and dizziness. Serious side effects are rare but may include allergic reactions, liver problems, and a small increased risk of high-grade prostate cancer.
