Generic Viagra contains sildenafil citrate, the same active ingredient found in brand-name Viagra. This means it offers the same efficacy in treating erectile dysfunction (ED). Sildenafil works by increasing blood flow to the penis, aiding in achieving and maintaining an erection.
How Sildenafil Works
Sildenafil inhibits an enzyme called phosphodiesterase-5 (PDE5). By blocking PDE5, sildenafil allows more cyclic GMP to accumulate. This increased cyclic GMP relaxes the muscles in the blood vessels of the penis, resulting in improved blood flow. This mechanism is key to its effectiveness in treating ED.
Generic vs. Brand-Name: Key Differences
The primary difference lies in the cost. Generic Viagra is significantly cheaper because pharmaceutical companies don’t spend money on brand marketing and research and development for already proven medications. The formulation and dosage are identical, ensuring the same medicinal benefits.
