Granpidam

Granpidam is an oral medication that contains the active ingredient sildenafil, a phosphodiesterase type 5 (PDE5) inhibitor. Marketed in the European Union, this prescription product is used to manage conditions where enhanced blood flow is beneficial. By inhibiting the PDE5 enzyme, Granpidam helps increase cyclic GMP levels, which promotes smooth muscle relaxation in targeted vascular tissues. It is supplied as a tablet for oral administration, typically taken as needed.

Granpidam is indicated for specific medical conditions where enhanced blood flow is beneficial.
