Man Health -> Sildenafil: Important Info -> Pharmaceuticals: Generics vs. Branded
Pharmaceuticals: Generic vs. Branded

Kamagra is made by Ajanta laboratory, India.  It is a generic brand that contains exactly the same active ingredient as the original Viagra™ made by Pfizer: Sildenafil Citrate.

Sildenafil Citrate is used to treat impotency in men, so Pfizer's Viagra™ and Ajanta's Kamagra work identically.

The only difference between the two is the price!

Why wasting lots of money on a brand name?  Generic Brands are just the same thing as the original, but they cost much less, so with the same money you can afford buying more.

Generic Brands of medicines are usually prescribed by GPs and the National Health Service, so their efficacy is out of doubt.
