Kamagra is the market name for Sildenafil, a drug most frequently used for treatment of erectile dysfunction and commonly known as Viagra. The drug is a prescription drug in most countries including Australia thus there might be restrictions in the amount of Kamagra dispensed from online stores. For one to get prescription drugs, the drug store keeper or dispensing pharmacist might need to see a signed prescription bearing the official stamp of the health facility or institution where the prescriber is based.
Action of Kamagra
Viagra – sildenafil citrate – contains very high quality ingredients like Ellagen, Pomegranate and Bioperine. This drug has helped a large number of men and has been named the best male enhancement pill by many.
Sildenafil works by inhibiting one isotype of an enzyme called Phosphodiesterase (isotype 5 or PDE5). This enzyme, PDE5 is mainly found in the corpora cavernosa (erectile tissue of penis), the eye and the liver. The enzyme usually breaks down cAMP which is responsible for formation of Nitric Oxide (NO) in the aforementioned tissues. NO is a strong vasodilator. Sildenafil therefore effectively increases concentration and by extension the vasodilative effects of NO in the aforementioned tissues. Dilatation of the arteries of the erectile tissues allows an increased amount of blood to flow in to these tissues and therefore causing erection. Use of sildenafil therefore increases both the strength and period of erection. These allow user to maintain hardness for much longer and to have increased intensity during intercourse. The drug is therefore indicated for men who fall just too fast – it can help men remain hard for up to twenty minutes. The drug has an early onset of action as one is likely to see effect of the drug within thirty minutes of use.
