How long will it be before Merck’s patent on Propecia expires? Obviously its Proscar patent expired a while ago, and since it is the same drug, one would think that Propecia would soon follow. Thoughts?
Merck still holds a process patent on 1mg finasteride. This is why generic 5mg (used to treat prostate problems) is available, but there is no legal generic 1mg. I seem to recall that they have more than 5 years still left on it. You can check out this past post for more info — Merck’s Drug Patent on Propecia Expiring?
