So why is this? Viagra, Levitra and Cialis belong to a class of drugs known as PDE5 inhibitors, and therefore have a common mechanism of action. Use of high-dose sildenafil after radical prostatectomy (RP) has been suggested to be associated with preservation of smooth muscle within the corpora cavernosa and daily use results in a greater return of spontaneous normal erectile function after RP compared to placebo in patients who were fully potent before surgery. However, each of these ED treatments is unique from one another. Neither are particularly palatable. When men experience erection problems such as erections that are not hard enough or erections that do not stay up, the underlying problem is blood flow. Once the doctor is sure of the right dose, the man can self-inject at home. However, if you have diabetes or high blood pressure you should better get Levitra pillsas vardenafil (the main ingredient of the drug) affects on the body gently.
Men who are on nitrate medications such as nitroglycerine should not take Viagra, since the combination of Viagra and nitrates can cause blood pressure to dip too low (hypotension). It's important to also remember that when ED is a complication of an underlying chronic condition such as high blood pressure or diabetes, the most effective treatment approach will likely involve focusing on the health problem itself. There's a wide range of treatments for erectile dysfunction. Self-injection of medications such as prostaglandin or trimix into the penis is also effective for many men. Your doctor will consider these factors as well as other conditions you have and possible interactions with other medications you take. Hypertension can disrupt erectile tissue function. Additionally, you may need blood or urine tests to rule out other conditions.
