Zhewitra 60 mg contains vardenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. It works by blocking the action of PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP). By inhibiting PDE5, vardenafil allows cGMP levels to increase, leading to smooth muscle relaxation in the blood vessels of the penis. This relaxation enhances blood flow to the penis, resulting in an erection. Dopamine is a neurotransmitter that plays a role in various physiological processes, including mood regulation, pleasure, reward, and motivation. While
Zhewitra 60 mg primarily affects the nitric oxide-cGMP pathway to facilitate erections, there isn't direct evidence to suggest that it directly influences dopamine levels. However, it's worth noting that sexual arousal and erectile function are complex processes involving multiple neurotransmitters, including dopamine. The enhancement of erectile function by medications like Zhewitra 60 mg might indirectly affect dopamine release in response to sexual stimulation and satisfaction. But as for direct influence on dopamine levels, that's not a documented effect of vardenafil.
