Vilitra 40 is a formulation of vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor primarily used to treat erectile dysfunction. Vardenafil works by enhancing blood flow to specific areas of the body, which is why it’s effective in treating erectile dysfunction. Its mechanism involves the inhibition of PDE5, an enzyme that breaks down cyclic GMP, a substance that relaxes smooth muscle and dilates blood vessels.
