It is commonly thought that finasteride was first conceived as a prostate medication and that, only by chance, was found to prevent hair loss. The fact is that in 1974 the researcher Imperato-McGinley described a group of genetically male children from the village of Salinas in the Dominican Republic who were deficient in the enzyme 5-alpha reductase. These male children had very low levels of DHT and throughout their life, their prostates remained small and they did not develop male pattern hair loss or acne.
The objective of the researchers was to find a drug that could block the 5-alpha reductase enzyme and mimic the abnormality found in these men. They could then use this drug to prevent both prostate enlargement (BPH) and hair loss. The decision was made, however, to obtain FDA approval for the medical indication first, rather than the cosmetic one. As a result, in 1992, Finasteride 5-mg was released under the brand name Proscar, for use in men over 50 with prostate enlargement (the prostate also has the type II enzyme). Five years later, i n 1997, the FDA approved finasteride 1-mg/day (Propecia) for the treatment of male pattern baldness.
non è che lo stavo chiedendo.. lo dicevo per certo
edit :
Questo anche per dire che ,se una ricerca è valida e si trova un 'implementazione decente il prodotto esce.
E' già capitato una volta e NON per caso...speriamo accada di nuovo.
