The chemical nepetalactone is to credit for your kitty's crazy reaction to catnip. The chemical, which is a mild hallucinogen, doesn't affect humans in the same sense as we do not rely as heavily on our noses as cats do. In fact, it doesn't even affect all cats.
Finasteride is a drug that belongs to the class of androgen inhibitors, which means that it blocks the production of male sex hormones. It is sold in the United States and Canada under the brand names Proscar and Propecia.
Finasteride is the active ingredient in the menâs hair-loss treatment Propecia, which has been available in Australia since the late 1990s. One tablet a day will arrest further hair loss in over 95 per cent of men and stimulate partial hair regrowth in two thirds of men.
