According to http://www.hairlosstalk.com/research/men/treatment1men.htm, Avodart is said to have a 50% better regrowth rate than Propecia. If one were to choose between staying on Propecia and achieve a lower regrowth rate or to switch to Avodart, what would be the pros and cons? Thanks.
Avodart is not currently approved by the FDA for the treatment of male pattern baldness (MPB). Propecia is the only oral medication approved by the FDA for MPB. Comparisons of Avodart with Propecia are conjecture by those who make such statements. It may be fair to say (without putting a percentage to it) that Avodart is reported (by physicians who use it regularly) to work better on some patients who are not getting good responses to Propecia.
The only real reservation I have about Avodart is that it has a very long half life in the order of WEEKS versus Propecia, which has a half life in the order of HOURS. A half life of a drug is the time it takes for half the drug to be cleared from your blood stream. This does not account for the drug cleared from tissue. The point is that Avodart is a strong medication and its full effects are not known. In my practice I do not generally recommend Avodart unless there are special circumstances.
