| One of the most efficient treatments of sexual dysfunction in males is Viagra oral therapy. The medication was initially invented to cure blood vessel problems and prevent heart attacks. Later on scientists concluded that the medication could dilate blood vessels.Impotence, also called erectile dysfunction) is a condition when the penis does not become firmer and larger when a male is sexually aroused, or when he cannot maintain an erection. Viagra may help a man with ED get and maintain an erection when he is sexually excited. Viagra is intended for males only and must be taken if recommended by a doctor.An erection is the result of an increase in blood flow into the genitalia and particularly to the penis. Viagra relaxes the arteries of the penis during sexual arousal, so blood flow to the organ soars.When taken orally before a meal, maximum medication concentration in plasma is observed within 30 to 120 minutes after administration.Viagra can work up to 4 hours, but the response decreases with time. When taken with foods containing a lot of fat, the effectiveness of the drug reduces.Viagra is contraindicated in men with heart problems, forcible deformities of the penis, in males predisposed to protracted erections triggered by blood cell disorders, liver problems (especially severe liver disorders), kidney problems and in males taking certain medications used for HIV or those over 65. Deaths have happened during sexual activity in males taking the pill.As well as other prescription drugs, Viagra can result in adverse side effects in some people. The most commonly observed side effects in males taken Viagra are splitting headaches, dyspepsia, diarrhea, lightheadedness, facial flushing, temporary visual changes (colour perception changes, light perception changes and blurred vision).If taken with other drugs (nitrate or nitroglycerin heart medicines), Viagra can result in dangerous drop in blood pressure, which can be fatal. Thus, before taking the drug, ask your medical practitioner about possible drug-to-drug interactions. |
