Sildenafil citrate 20 mg and Viagra contain the same active pharmaceutical ingredient: sildenafil citrate. This means they share identical chemical composition and structure. The difference lies primarily in the formulation–the inactive ingredients used to create the tablet. These excipients can vary between brands, affecting factors like tablet size, disintegration time, and absorption rate, though these variations are usually minor.
Viagra is the brand name for sildenafil citrate, manufactured by Pfizer. Generic sildenafil citrate 20 mg tablets from other manufacturers must meet the same strict regulatory standards for bioequivalence. Bioequivalence demonstrates that the generic product performs comparably to the brand-name drug in terms of absorption and bioavailability in the body.
Therefore, while slight differences in excipients may exist, the therapeutic effect of 20 mg of generic sildenafil citrate is expected to be comparable to 20 mg of Viagra.
Always consult a physician or pharmacist if you have questions about medication equivalence or potential interactions. They can provide tailored advice considering your individual health circumstances.
