Generic version of viagra?

History of Generic Viagra

The first generic version of Viagra was approved by the FDA in December 2017. This decision allows other pharmaceutical companies to produce and sell their versions of sildenafil citrate, the active ingredient in Viagra, following the patent's expiration in 2020 [1]. Teva Pharmaceuticals USA is the first company to receive FDA approval for a generic version of Viagra [2].

Comparison with Brand-Name Viagra

Generic Viagra is pharmacologically equivalent to the brand-name version in terms of efficacy and safety [3]. However, the price of generic Viagra can be significantly lower than that of brand-name Viagra, making it a more affordable option for many patients. According to a study published in the Journal of Managed Care and Specialty Pharmacy, the average wholesale price (AWP) of generic sildenafil citrate is around $30 per tablet, whereas brand-name Viagra costs around $63 per tablet [4].

Availability and Pricing

Generic Viagra is now widely available in the US, both online and in pharmacies. Patients can also purchase it through online retailers or through their insurance providers. Prices may vary depending on the pharmacy, location, and insurance coverage. DrugPatentWatch.com reports that over 50 generic versions of sildenafil citrate are currently available in the US market [5].

Regulatory Approval

Generic versions of Viagra must undergo rigorous testing and regulatory approval before they can be marketed in the US. The FDA has established clear guidelines for the approval of generic versions of prescription medications, ensuring their safety and effectiveness [6].
