The big picture view
Active pharmaceutical ingredient: sildenafil citrate. Drug class: phosphodiesterase type 5 inhibitors (PDE5 inhibitors).
Primary indication: pharmacologic treatment of erectile dysfunction in adult men. These medicines work by increasing blood flow to the penis during sexual arousal through vascular smooth muscle relaxation.
Dosage strengths often encountered outside regulated markets: 50 mg and 100 mg tablets. FDA-approved sildenafil products in the United States are dispensed only by prescription and are available in 25 mg, 50 mg, and 100 mg strengths.
What It Is and Uses for which this is intended
Products labeled Kamagra are marketed for erectile dysfunction. They contain sildenafil, the same molecule found in several licensed preparations. Kamagra sold online is often an imported or unapproved formulation, and quality cannot be guaranteed.
Heads up: these medicines do not create sexual desire and are not performance enhancers for sports or bodybuilding.
