Finasteride
Finasteride serves as a primary treatment for men experiencing thinning or regression of the frontal and vertex scalp hair. Well-known brands such as Propecia and Finpecia are available to manage what is clinically identified as Androgenetic Alopecia. This page features 2 generic medications in our current catalogue offering support for hair regrowth.
Key points
- Blocks the enzyme 5-alpha reductase, lowering DHT levels responsible for shrinking hair follicles in androgenetic alopecia.
- Marketed as Propecia and Finpecia, both delivering the same active compound in film-coated tablet form.
- Sexual side effects or mood changes are reported by some users, typically easing after the medication is stopped.
What is Finasteride?
Finasteride is a pharmaceutical formulation primarily utilised to address male pattern baldness. By blocking specific enzymes in the body, it targets the hormonal pathways that lead to follicle miniaturisation. Different brands such as Propecia and Finpecia rely on the same active compound, allowing a choice based on preference.
What Finasteride is used for
This medication is specifically designed to treat hair loss caused by hereditary factors. It is commonly used for Androgenetic Alopecia, which manifests as a receding hairline or thinning at the crown. Regular use over an extended period may stabilise condition progression and stimulate hair maintenance.
How does Finasteride work?
Finasteride functions by inhibiting 5-alpha reductase, an enzyme that converts testosterone into dihydrotestosterone (DHT). High levels of DHT are linked to the shrinking of hair follicles in sensitive areas of the scalp. By lowering systemic DHT levels, the medication reduces the impact of this hormone on hair follicles, allowing them to retain their size and productivity.
Finasteride brands and forms
The global market offers both the originator brand, Propecia, and various generic equivalents like Finpecia. These formulations usually come as a film-coated tablet, ensuring consistent dosing. When looking for effective options within Prostate Health, patients often prioritise accessibility and formulation quality. Since the generic versions contain the same concentration of the active ingredient, efficacy remains comparable to the original medications.
