Caverta 50 mg is a medication used to treat erectile dysfunction (ED), containing Sildenafil Citrate, the same active ingredient found in Viagra. Sildenafil works by enhancing the effects of nitric oxide, which relaxes the muscles in the blood vessels of the penis and allows increased blood flow, thereby helping to achieve and maintain an erection when sexually stimulated. Understanding the pharmacokinetics of Caverta 50 mg is crucial for understanding how the body absorbs, distributes, metabolizes, and eliminates the drug.
