What is Kamagra?
Kamagra is a trade name for sildenafil citrate, which is sold by Pfizer under the name Viagra. It is a symptomatic treatment for erectile dysfunction.
Kamagra warnings and precautions
If sildenafil is taken at the same time as a high-fat meal, there is a slowing of the absorption of the drug. Maximum plasma concentration is delayed by up to an hour and the maximum concentration reached may be as much as a third lower. Sildenafil may increase blood flow in the eye. If there is a sudden loss of vision, urgent medial care should be sought. You should inform your doctor if you have a recent history of heart disease or arrhythmia, heart attack, stroke or congestive heart failure, or if you have abnormal blood pressure, coronary artery disease, liver or kidney disease, any blood cell disorder, hemophilia, a stomach ulcer or any anatomical deformity of the penis such as Peyronie’s disease. Nitric oxide donors, including organic nitrites and nitrates such as nitroglycerin, sodium nitroprusside and amyl nitrite and its analogues (poppers) taken together with sildenafil may lead to a dangerous drop in blood pressure. Grapefruit of grapefruit juice should be avoided because it may potentiate the dosage of sildenafil leading to symptoms of overdose.
Contraindications for Kamagra
Sildenafil should not be used by patients with severe liver or renal impairment, low blood pressure, a recent history of stroke or heart attack or genetic degenerative retinal disorders.
What if I take an accidental overdose of Kamagra?
Symptoms of a Kamagra overdose include lightheadedness, sudden indigestion, nausea and vomiting, vision and hearing impairment, irregular heartbeat, tachycardia, myocardial infarct or priapism. If any of these conditions becomes painful, emergency medical care should be sought.
When should you not take Kamagra?
Kamagra should not be used when taking glyceryl trinitrate (nitroglycerin) or other vasodilators which release nitric oxide, including sodium nitroprusside and amyl nitrite (known recreationally as “poppers”). Severely decreased liver function or renal function is also a contraindication. Kamagra should not be taken by patients with low blood pressure or who have recently suffered a stroke or heart attack. Use of the drug should also be avoided by patients with genetic retinal disorders.
Abuse of Kamagra for recreational use
Sildenafil is increasingly popular as a sexual heightener even among people who do not need it for erectile dysfunction. A number of popular myths have grown up including those that the drug increases penis size and libido. Because dance drugs such as amphetamine and MDMA or ecstasy are known to inhibit erections, Sildenafil is often taken in combination with those to overcome that effect.
History of Kamagra
Sildenafil was synthesized in Pfizer’s research center in England as a potential treatment for high blood pressure and angina pectoris. In clinical trials it was noted that the drug was not effective for angina, but that it tended to induce erections among male subjects. It was patented for this use in 1996 and approved in the US by the FDA in March 1988. Pfizer’s patent on Viagra is set to expire in the US in March, 2012, however Pfizer continues to hold a monopoly on manufacturing the drug in Britain.
