Vidalista 60 mg contains tadalafil as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. It primarily acts on the enzyme PDE5, which is found predominantly in the smooth muscle cells of the corpus cavernosum in the penis. However, it does not directly bind to neurotransmitter receptors.

PDE5 inhibitors like Vidalista 60 mg work by inhibiting the breakdown of cyclic guanosine monophosphate (cGMP), a molecule that promotes smooth muscle relaxation and increased blood flow in the penis during sexual stimulation. By inhibiting PDE5, tadalafil prolongs the effects of cGMP, leading to enhanced erectile function.

While tadalafil primarily targets PDE5, it may also have some affinity for other phosphodiesterase enzymes, albeit to a lesser extent. Additionally, the effects of tadalafil on other neurotransmitter systems, if any, are not as well-established as its effects on the PDE5 enzyme. Therefore, it is not typically classified as directly binding to neurotransmitter receptors.
