Cenforce 120 mg is a generic medication that contains sildenafil citrate, which is also the active ingredient in Viagra. Generic medications like Cenforce do not have individual patents because they are versions of the original branded drug that have the same active ingredient, dosage form, strength, and route of administration. The patent for sildenafil citrate was originally held by Pfizer, which marketed it under the brand name Viagra. However, patents typically expire after a certain period of time, allowing other pharmaceutical companies to produce generic versions of the medication once the patent has expired. Therefore, Cenforce 120 Mg, being a generic version of sildenafil citrate, is manufactured by various pharmaceutical companies worldwide under different brand names. It is important to note that patents and intellectual property rights may vary by country, and generic manufacturers must comply with local regulations regarding patent expiration and marketing approval. |
