Manufacturers of generic Viagra must adhere to strict guidelines to ensure product quality and safety. The process begins with obtaining a copy of Pfizer’s patent for sildenafil citrate, the active ingredient in Viagra. Once this is secured, the manufacturer produces sildenafil citrate using their own manufacturing process.
Quality control is paramount. Rigorous testing is conducted throughout the manufacturing process to verify the purity, potency, and stability of the drug. This includes checking for impurities and ensuring consistent dosage.
Subsequently, the manufacturer files a New Drug Application (ANDA) with the FDA. The ANDA provides comprehensive data demonstrating bioequivalence to the brand-name drug. This means that the generic drug performs similarly in the body as the original Pfizer Viagra. The FDA reviews this data extensively, including the manufacturing process validation and quality control results.
FDA approval is not guaranteed. The agency conducts thorough inspections of the manufacturing facilities to ensure compliance with Good Manufacturing Practices (GMP). Only after successful completion of this rigorous review process will the FDA grant approval, permitting the generic Viagra to be marketed in the United States.
