Modula 5 mg is a medication containing the active ingredient tadalafil, which is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in men. Tadalafil is also sold under the brand name Cialis. Tadalafil works by increasing blood flow to the penis during sexual stimulation, which helps men achieve and maintain an erection sufficient for sexual activity. It does this by inhibiting the enzyme PDE5, which is responsible for regulating blood flow in the penis.
