Many common medications for treating hypertension, depression, and high blood lipids can contribute to erectile dysfunction (see above). Treatment of hypertension is an example. There are many different types (classes) of anti-hypertensive medications (medications that lower blood pressure); these include beta-blockers, calcium channel blockers, diuretics (medications that increase urine volume), angiotensin converting enzyme inhibitors (ACE inhibitors), and angiotensin receptor blockers (ARBs). Anti-hypertensives may be used alone or in combination(s) to control blood pressure. Different classes of anti-hypertensives have different effects on erectile function. Inderal (a beta blocker) and hydrochlorothiazide (a diuretic) are known to cause erectile dysfunction, while calcium channel blockers and ACE inhibitors do not seem to affect erectile function. On the other hand, angiotensin receptor blockers (ARBs) such as losartan (Cozaar) and valsartan (Diovan), may actually increase sexual appetite, improve sexual performance, and decrease erectile dysfunction. Therefore, choosing an optimal anti-hypertensive combination is an important part of treating erectile dysfunction Aside from the well-known complications that the use and abuse of these drugs can cause, ED is not often mentioned. However, use of these drugs can cause ED. These drugs not only affect and often times suppress the central nervous system, but can also cause serious damage to the blood vessels, resulting in permanent ED. Vasoactive drugs may also be injected intracavernosally. Such therapy represents an important second-line therapy for erectile dysfunction. It is the most effective pharmacologic treatment but has a high dropout rate because of the associated pain and apprehension involved. Phentolamine is an -blocker that was used in initial studies; its efficacy is poor, but it may be used in combination with other agents. Papaverine is a nonspecific PDE inhibitor and was the first effective intracavernosal therapy for erectile dysfunction. Currently, intracavernosal alprostadil therapy is preferred; it is more effective than other agents and produces fewer side effects. In a comparison study comparing alprostadil, a papaverine–phentolamine combination and papaverine alone, rates of success (ability to achieve and maintain an erection) of 72%, 61% and 31% were reported respectively.54 No patients in the alprostadil group experienced priapism, as compared with 2% and 4% of patients in the combination therapy and papaverine-only groups respectively. On the other hand, patients who used alprostadil were the only ones to report penile pain. For patients who do not respond to or do not tolerate alprostadil monotherapy, a triple mixture of papaverine, phentolamine and alprostadil may be prescribed. Such combination therapy has been shown to be more effective and, because of a lower dose of alprostadil, results in less pain.62 Complications of intracavernosal injections include pain, priapism and fibrotic changes at injection sites. The very fact that young males actually think they need this drug is all by itself alarming. But it's even more alarming to realize that Pfizer appears to be doing very little to restrict the sales of Viagra for recreational use. viagra Quit Smoking For example, surgical patients can opt for a "nerve-sparing" procedure less likely to interfere with sexual function.

Sometimes your hormones get out of balance and this causes erectile dysfunction. Your doctor will decide if you need blood tests to check your hormones. Tadalafil differs from sildenafil and vardenafil in its chemical structure and its lack of inhibition of PDE type 6. Tadalafil exhibits a prolonged half-life of 17.5 hours, and the time to peak concentration is about 2.0 (range 0.5–12.0) hours in healthy volunteers.37 Among men with erectile dysfunction, a significantly higher percentage of attempts at sexual intercourse were successful up to 24–36 hours after use of tadalafil compared with placebo.37,40,41 The pharmacokinetics of tadalafil is not clinically influenced by food or alcohol intake, or by intrinsic factors such as diabetes, or renal or hepatic impairment.41
