5-Alpha Reductase Inhibitors: Uses, Common Brands, and Safety Info

5-Alpha Reductase Inhibitors

Uses

5-Alpha Reductase Inhibitors are a class of medications that inhibit the activity of the enzyme 5-alpha reductase. This enzyme converts testosterone into dihydrotestosterone (DHT), which is responsible for the development of certain conditions like benign prostatic hyperplasia (BPH) and male pattern baldness. By blocking this enzyme, 5-Alpha Reductase Inhibitors can help reduce the symptoms associated with BPH, such as frequent urination, difficulty starting and maintaining urination, and the need to urinate urgently or frequently during the night. In addition to treating BPH, these inhibitors can also be used off-label to promote hair growth in male pattern baldness. However, it is worth noting that the improvement in hair growth may take several months to become noticeable, and the medication must be continued to maintain the effect.

Common Brands

Some commonly prescribed 5-Alpha Reductase Inhibitors include: 1. Finasteride (Proscar, Propecia): Finasteride is available in different strengths for treating BPH (Proscar) and hair loss (Propecia). 2. Dutasteride (Avodart): Dutasteride is primarily used for the treatment of BPH. While these are the most commonly known brands, several generic versions of these medications are also available, which can be more cost-effective options.
