Does Cut Proscar Have a Shorter Half-Life than Propecia?

Is it possible that cut pills (generic Proscar in fourths) have a shorter half life than Propecia with its protective coating still intact?

Propecia and Proscar aren’t time released medications, so the protective coating wouldn’t change the half-life of the medication. A big reason for the coating is to protect pregnant women, as women that handle a cut finasteride pill run the risk of absorbing the active ingredient through the skin. The coating also helps make the pill easier to swallow and helps to extend the shelf-life by protecting it from the environment to some degree.

I know you realize the following information, but just in case some readers out there aren’t aware — some people choose to cut a Proscar (5mg finasteride) pill to make it equal to Propecia (1mg finasteride). Different generic pharmaceutical makers may make different shapes and sizes of the pill, but generally it’s easier to cut the Proscar into 4 equal pieces (making the dose 1.25mg). Why do people cut the Proscar? Well, Proscar (and the generic variant) is much cheaper than Propecia, which has no generic legally available in the US due to patent laws.
