Used primarily in the treatment of erectile dysfunction, it works by increasing blood flow to the penis during sexual stimulation. It belongs to a class of drugs that inhibit phosphodiesterase type 5 (PDE5), helping maintain an erection by preserving cyclic guanosine monophosphate (cGMP) levels in smooth muscle cells. The compound is known for its moderate duration of action, offering a balance between onset time and prolonged effectiveness. It is taken orally, typically before anticipated sexual activity, and its efficacy can be influenced by food intake and individual metabolic factors.
