Tadagra 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains tadalafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Tadagra 20 mg is typically available in tablet form. The recommended starting dosage for most men with ED is 10 mg taken orally before activity. However, the dosage may be adjusted based on individual response and tolerability, with a maximum recommended dose of 20 mg per day. Tadalafil, the active ingredient in Tadagra 20 mg, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This action leads to increased levels of cyclic guanosine monophosphate (cGMP), which relaxes the smooth muscles in the blood vessels of the, allowing for increased blood flow during stimulation. This results in an erection that is firm and sustained enough for satisfactory activity.
