Kamagra vs Viagra are both effective treatments for erectile dysfunction, containing the same active ingredient—sildenafil citrate—which enhances blood flow to the penis to support firm and lasting erections. While Viagra is the original, FDA-approved brand developed by Pfizer, Kamagra is a generic alternative produced by various manufacturers, often available at a lower cost. Both medications deliver similar effects, but Kamagra may come in additional forms like oral jelly or chewable tablets, offering more flexibility for users.
