A man who has erectile dysfunction is unable to achieve or maintain an erection that is sufficiently firm for sexual activity. Signs of erectile dysfunction (ED), commonly referred to as impotence, may include the capacity to obtain an erection occasionally but not every time, the ability to achieve an erection that does not persist long enough to participate in sexual intercourse, or the difficulty to get an erection at any time. The condition may have physical causes such as injury to the smooth muscles and fibrous tissues in the penis, or damage to the nerves or arteries. ED can also result from certain illnesses and health issues, such as diabetes and high blood pressure.
Known as "the little blue pill," Viagra has brought in billions of dollars for copyright, the pharmaceutical behemoth since it was introduced in 1998. However, erectile dysfunction medication has been connected to severe adverse effects, such as melanoma, heart problems, and loss of eyesight and hearing.
Men with erectile dysfunction (ED) can be treated with the oral drug Viagra. When blood flow to the penis rises, the penis expands and becomes hard, resulting in an erection. Blood flows into the corpora cavernosa, two lengthy chambers inside the penis, where spongy tissue gathers the blood. This pressure causes the penis to enlarge.
Viagra functions by selectively inhibiting phosphodiesterase type 5 (PDE5) specific to cyclic guanosine monophosphate (cGMP), which causes blood vessels to relax and improves blood flow to the penis. Viagra helps a man with ED get and maintain an erection when he is sexually aroused or stimulated, but it does not automatically produce an erection.
There are various conditions that the active component in Viagra can cure. Adults suffering from pulmonary arterial hypertension (PAH) are taken sildenafil. The pulmonary artery, the blood channel that carries blood from the heart to the lungs, experiences excessively high blood pressure due to PAH, a progressive, potentially fatal illness. Sildenafil slows the disease's progression and deterioration while also enhancing a patient's capacity for activity. Shortness of breath while exercising, fainting episodes, lightheadedness, ankle or leg edema, chest discomfort, and an accelerated heartbeat are some of the signs of this serious illness.
Serious side effects are possible with Viagra. These can include a persistent erection (priapism), abrupt loss of eyesight in one or both eyes, and sudden loss of hearing. After using Viagra, some men have also suffered from heart attacks, strokes, abnormal heartbeats, and even passed away. It was discovered that the majority of these guys, though not all of them, had cardiac issues before using Viagra. Whether Viagra caused or made these issues worse is uncertain.
When taking Viagra with other drugs, some drug interactions may arise. These interactions have the potential to produce unanticipated side effects and either boost or decrease the effects of Viagra.
It has been demonstrated that cimetidine (brand name Tagamet), a nonspecific CYP inhibitor used to prevent the generation of stomach acid, raises the level of sildenafil in patients' blood. It has also been demonstrated that CYP3A4 inhibitors raise sildenafil blood concentrations when used with Viagra.
