Description

A synthetic 4-azasteroid compound that is a selective inhibitor of both the type 1 and type 2 isoforms of steroid 5 alpha-reductase, an intracellular enzyme that converts testosterone to DHT.

Dutasteride is chemically designated as (5α,17β)-N-{2,5 bis(trifluoromethyl)phenyl}-3-oxo-4- azaandrost-1-ene-17-carboxamide. The empirical formula of dutasteride is C27H30F6N2O2, representing a molecular weight of 528.5

Dutasteride is a white to pale yellow powder with a melting point of 242° to 250°C. It is soluble in ethanol (44 mg/mL), methanol (64 mg/mL), and polyethylene glycol 400 (3 mg/mL), but it is insoluble in water.

Dutasteride is used for:

Treating symptoms of benign prostatic hyperplasia (BPH) or enlargement of the prostate gland. It also helps to reduce the risk of urinary blockage and the need for surgery to treat BPH. It may be used alone or along with another medicine (tamsulosin).

Dutasteride is a 5 alpha-reductase enzyme inhibitor. It works by lowering levels of a hormone called dihydrotestosterone (DHT), which is a major cause of prostate growth. Lowering DHT leads to shrinkage of the enlarged prostate gland.

Dutasteride is a medication used to treat benign prostatic hyperplasia (enlarged prostate) and androgenetic alopecia (pattern hair loss).

Medical uses

Avodart (dutasteride) 500 µg soft capsules
Prostate enlargement
Dutasteride is occasionally used for treating benign prostatic hyperplasia (BPH); colloquially known as an "enlarged prostate". It is approved by the Food and Drug Administration (FDA) in the U.S. for this indication.

Prostate cancer

Pattern hair loss

Dutasteride is approved for the treatment of male androgenetic alopecia in South Korea at a dosage of 0.5 mg per day. It has been found in several studies to improve hair growth in men more rapidly and to a greater extent than 2.5 mg/day finasteride. Dutasteride has also been used off-label in the treatment of female pattern hair loss.

Excessive hair growth

Although no reports specific to dutasteride currently exist, 5α-reductase inhibitors like finasteride have been found to be effective in the treatment of hirsutism (excessive facial and/or body hair growth) in women. Dutasteride may be more effective than finasteride for this indication due to the fact that its inhibition of the 5α-reductase enzyme is comparatively more complete.

Is There Any Difference in Side Effects Between Dutasteride and Finasteride?

GlaxoSmithKline protocol ARI40001 compared dutasteride (0.5 mg/d) with finasteride (5 mg/d) for 1 year.18 There were no significant differences in the incidence of the most common drug-related adverse events between the dutasteride and finasteride groups. The only adverse events that the investigators considered to be drug-related that occurred at an incidence of more than 2% were impotence and decreased libido.
