Aurogra 100 is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is the same active ingredient found in Viagra. Aurogra 100, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This inhibition leads to an increase in cyclic guanosine monophosphate (cGMP) levels, which relaxes the smooth muscles and increases blood flow to the penis, helping to achieve and maintain an erection during sexual stimulation.
