Sildenafil Diagnosis
Sildenafil is used to treat male sexual function problems (erectile dysfunction) by blocking a certain enzyme (phosphodiesterase-PDE5) in the body. In combination with sexual stimulation, sildenafil works by helping the blood flow into the male organ to achieve and maintain an erection. This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). Practice “safe sex” such as using latex condoms. Consult your doctor or pharmacist for more details.
This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional. Sildenafil is also available in other strengths for treating high blood pressure in the lungs (pulmonary arterial hypertension). Do not substitute one form of this drug for the other. Before starting proper treatment and proper diagnostic tests your doctor will ask some basic and some important questions.
Your doctor can ask about the current situation of your health and body, he may also ask you about your sexual activity, he may also ask how and when symptoms appears, he may also ask about whether you have used any other types of treatments or any other medicines. Your doctor may also call your partner in order to check the emotional changes and other activities. He can ask many types of questions from your partner, he can also ask many other types of question from you in order to get better idea about your health and condition. In order to confirm the disease level in your body he may conduct some sort of medical tests, he may conduct some of the following medical tests in order to confirm the diseases in you.
The physiologic mechanism of erection of the male organ involves release of NO in the corpus cavernosum during sexual stimulation. NO then activates the enzyme guanylate cyclase, which results in increased levels of cGMP, causing smooth muscle relaxation in the corpus cavernosum and allowing blood inflow and tumescence. Sildenafil inhibits the enzyme phosphodiesterase, which metabolizes cGMP and thus increased levels of cGMP induce arteriolar smooth muscle relaxation and vasodilatation. Sildenafil induces penile tumescence by improving the blood supply of corpora cavernosa; it is assumed that this increased blood flow, in turn, will reduce the perfusion-limited hypoxia.
