Introduction to Sildenafil and Viagra

Sildenafil is a medication widely used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). It is available as a brand-name drug, Viagra, and as generic drugs under various names.

Sildenafil's uses: erectile dysfunction and pulmonary arterial hypertension

Sildenafil works by inhibiting the phosphodiesterase type 5 enzyme, which increases blood flow to the penis and clitoris, promoting lubrication in the vagina and enhancing sexual arousal. It is used to treat erection problems and pulmonary hypertension.

Pfizer's patent on Viagra and its impact on Indian copycat versions

Pfizer, a US pharmaceutical giant, holds the patent on Viagra. However, in India, various copycat versions of the drug are available at significantly lower prices. For example, while Pfizer's Viagra is available at Rs 527 per tablet, desi versions such as Manforce, Suhagra, Penegra, and Zenegra are available for an average of Rs 52, which is just one-tenth of the price of the original.

Available strengths of sildenafil tablets: 25mg, 50mg, and 100mg

Sildenafil tablets are available in various strengths, including 25mg, 50mg, and 100mg. The tablets are taken orally and swallowed whole, preferably on an empty stomach or after consuming a low-fat meal.

Comparing brand-name Viagra and generic versions in India

While the brand-name Viagra is relatively expensive in India, its generic versions are available at a lower cost. This makes the medication more accessible to a wider range of people in the country.

Prescription practices and concerns about misuse and abuse in India

Despite the drug's benefits, doctors in India prescribe sildenafil only in cases where there are no other options available. The drug is also sold loosely without proper checks, leading to concerns about its misuse and abuse. Efforts are needed to ensure safe and responsible access to this important medication.
