Men suffering from erectile dysfunction (ED) can take a medication called Kamagra Oral Jelly. A medication class known as phosphodiesterase type 5 (PDE5) inhibitors is comprised of the active ingredient sildenafil. Thanks to its ability to relax blood vessels, sildenafil helps improve erectile function by increasing blood flow to the penis. A medical professional should determine the proper dosage as it comes in different strengths. To aid in erection, kamagra is usually taken just before engaging in sexual activity. It should be taken as prescribed by a physician.
