What is dutaseride? How does it work (mechanism of action)?
Dutasteride is a medication used for the treatment of benign prostatic hyperplasia (BPH) also known as an enlarged prostate. Dutasteride belongs to a class of medication called 5-alpa reductase inhibitors. Male hormone dihydrotestosterone (DHT) is primarily responsible for development and enlargement of the prostate gland. Testosterone is converted into DHT by 5-alpha reductase enzyme. Dutasteride blocks 5-alpha reductase enzyme and prevents excessive DHT production in the prostate gland. This delays the progression of an enlarged prostate and improves symptoms of BPH.
The FDA approved dutasteride in November 2001.
What are the uses for dutasteride?
What are the side effects of dutasteride?
Dutasteride causes many sexual side effects.
Common side effects are:
Allergic reaction such as swelling under the skin may occur. Dutasteride also increases risk of high-grade prostate cancer. Patients must contact their healthcare professional if unusual reactions to dutasteride occur.
What is the dosage for dutasteride?
The recommended dose of dutasteride is 0.5 mg once daily. Do not chew the medication and do not administer to pediatric patients.
Which drugs or supplements interact with dutasteride?
Medications such as ketoconazole (Nizoral), cimetidine (Tagamet), diltiazem (Cardizem), verapamil (Calan), ritonavir (Norvir) and clarithromycin (Biaxin) slow down the breakdown of dutasteride. This may lead to increased levels of dutasteride in the body, increasing side effects such as decreased libido, erectile dysfunction, and impotence.
Medications such as carbamazepine (Tegretol) and primidone (Mysoline) increase the breakdown of dutasteride in the body. This may lead to decreased levels of dutasteride in the body, lowering the beneficial effects of the medication.
Is dutasteride safe to take if I'm pregnant or breastfeeding?
It is not known whether dutasteride enters breast milk.
What else should I know about dutasteride?
What preparations of dutasteride are available?
Dutasteride is available as 0.5 mg liquid-filled capsules.
How should I keep dutasteride stored?
Dutasteride capsules should be stored between 15 C to 30 C (59 F to 86 F).
Dutasteride is available in generic form, but must be prescribed by a doctor or other health-care professional. The brand name available for dutaseride is Avodart.

Benign Prostatic Hyperplasia
Benign prostatic hyperplasia (BPH or enlarged prostate) is very common in men over 50 years of age. Half of all men over the age of 50 develop symptoms of BPH, but few need medical treatment. This noncancerous enlargement of the prostate can impede urine flow, slow the flow of urine, create the urge to urinate frequently and cause other symptoms like complete blockage of urine and urinary tract infections. More serious symptoms are urinary tract infections (UTIs) and complete blockage of the urethra, which may be a medical emergency.
BPH is not cancer. Not all men with the condition need treatment, and usually is closely monitored if no symptoms are present. Treatment measures usually are reserved for men with significant symptoms, and can include medications, surgery, microwave therapy, and laser procedures. Men can prevent prostate problems by having regular medical checkups that include a prostate exam. Contact your doctor or other medical professional if you have these symptoms:
- Painful urination
- Blood in the urine
- Difficult urinating
- A frequent urge to urinate
- Dribbling of urine
Dutasteride vs. Finasteride
Dutasteride (brand name Avodart) and finasteride (brand name Procar) are medications prescribed for the treatment of an enlarged prostate (benign prostatic hyperplasia, BPH). Both dutasteride and finasteride delay the progression of an enlarged prostate gland, which improves symptoms of BPH.
The side effects of both drugs are mostly sexual problems like breast enlargement, impotence (erectile dysfunction, ED). However, dutasteride may cause allergic reactions, and increases the risk of high-grade prostate cancer. In rare cases, finasteride has caused male breast cancer.
The recommended dose for dutasteride is 0.5 mg once daily. finasteride should be used with caution if you have liver dysfunction. Neither drug should be used in females or pediatric patients.
