Tadalista 20 mg, a drug used to treat erectile dysfunction, has tadalafil as its active ingredient. Type 5 phosphodiesterase is inhibited by tadalista. Tadalafil, a component in Tadalista, promotes blood flow to the penis, which helps cure erectile dysfunction (ED). Additionally, your physician might suggest addressing the symptoms of pulmonary arterial hypertension (PAH) and benign prostatic hypertrophy, which is an enlarged prostate. ED is treated with Tadalista by inhibiting the Phosphodiesterase type 5 (PDE5) enzyme.
