Sildenafil Hemi Pharma is an oral steroid that is used to treat erectile dysfunction. The active ingredient in Sildenafil Hemi Pharma is sildenafil, which is a PDE5 inhibitor. This means that it works by inhibiting the enzyme that is responsible for breaking down cGMP, which is responsible for relaxing the smooth muscles in the penis. This results in increased blood flow to the penis, which leads to an erection. Sildenafil Hemi Pharma is available in 25 mg tablets.
