Many men of different ages suffer from erectile dysfunction. Erectile dysfunction, also known as impotence, is known as the failure to achieve or maintain an erection adequate enough for sexual activity. Erections occur when blood vessels that carry blood to the penis expand, letting blood flow in, while the blood vessels used to carry blood out of the penis are constricted, which restricts blood flow from leaving the penis. In simple terms, blood comes in but it does not come out, creating an erection. In men who suffer from erectile dysfunction, the blood vessels to the penis do not allow for sufficient blood flow to reach the penis and create an erection. Erections can be caused by a number of psychological and physiological factors that affect the vascular, hormonal, or nervous systems.
One of the chief combatants of erectile dysfunction are phosphodiesterase type 5 (PDE5) inhibitors – also known as erectile dysfunction medication. The top three FDA-approved brands are Viagra, Cialis, and Levitra. Each one contains a PDE5 inhibitor (Sildenafil, Tadalafil, and Vardenafil) that works to increase blood flow to the penis. They inhibit the PDE5 enzyme, and this enzyme works to destroy cGMP (what is responsible for the delivery and removal of blood to the penis through the blood vessels). With the PDE5 inhibited, the cGMP is able to do its job and get blood to the penis so you can have a long lasting and hard erection throughout sexual stimulation.
According to https://www.acheter-levitra.net/levitra-instructions.html side effects of erectile dysfunction medication include nasal congestion, nausea, headaches, acid indigestion, facial blushing, and temporary vision impairment. However, there are more severe side effects that if they occur, warrants immediate medical treatment: chest pain, blood pressure fluctuations, allergic reactions, chest pain, prolonged erection for over four hours (called priapism), numbness in your extremities, dizziness, hearing and vision loss, and loss of memory.
Men taking certain medications, such as nitrates, alpha blockers, and calcium channel blocking drugs should first speak with a medical professional before taking Levitra. The combination of both these drugs can severely lower your blood pressure, causing hypotension. As well, if you suffer from certain medical conditions, such as liver or kidney problems, diabetes, heart disease, cardiovascular disease, or have a recent history of stroke or heart attack, you should first speak to your doctor before taking erectile dysfunction medication as it can act adversely. Your doctor might want to have regular checkups to monitor you and evaluate your condition while on Viagra (Sildenafil), Cialis (Tadalafil), or Levitra (Vardenafil).
All erectile dysfunction medications should not be taken more than once in a 24 hour period. Taken more than once in a 24 hour period, the medication can lead to more severe side effects including priapism. Different erectile dysfunction pills last in the body at different times. Sildenafil lasts from four to six hours, Vardenafil lasts for 5 hours and Tadalafil lasts for 36 hours, which is good for men who do not want to take a pill every day.
