Caverta 50 Mg is a medication that primarily contains Sildenafil Citrate, a well-known ingredient used to treat ED. Sildenafil Citrate works by increasing blood flow to the penis, which helps achieve and maintain an erection. This process involves the inhibition of the enzyme phosphodiesterase type 5 (PDE5), which normally limits blood flow to the penile area. By blocking PDE5, Caverta helps relax the blood vessels and improve circulation, facilitating an erection in response to sexual stimulation.
