Caverta 100 mg is a medicine used to treat erectile dysfunction (ED) in men. The main ingredient in Caverta 100 is sildenafil citrate, which is an inhibitor of phosphodiesterase type 5 (PDE5). PDE5 is an enzyme that breaks down cyclic guanosine monophosphate (cGMP), which is a molecule that helps relax the smooth muscles in the penis and improve blood flow.

Men with ED have less cGMP in their bodies, which means less blood flow to the penis and a failure to get and keep an erection. Caverta 100 works by stopping PDE5 from doing its job. This increases the production of cGMP and lets more blood move to the penis, which leads to a strong, long-lasting erection.

Caverta 100 is usually taken 30 minutes to an hour before sexual action, and the effects can last up to 4 hours. It's important to know that Caverta 100 won't give you an erection if you're not sexually stimulated. Instead, it works by improving the body's natural reaction to sexual stimulation.
