More severe risks, though rare, include priapism (a painful erection lasting longer than four hours), sudden hearing loss, and myocardial infarction (heart attack). Despite its success and widespread use, viagra 6 hours is not without side effects and potential risks. Common side effects include headaches, flushing, indigestion, nasal congestion, and impaired vision. Therefore, it is recommended that Viagra be used under the guidance of a healthcare provider.
Viagra’s role in treating this condition lies in its effects on blood flow. It can stem from both psychological and physiological causes, including diabetes, cardiovascular disease, hormonal imbalances, and psychological factors such as anxiety or depression. Erectile dysfunction is a condition where there is a difficulty in achieving or maintaining an erection suitable for sexual intercourse. NO is a natural chemical that relaxes muscles in the penis, increases blood flow, and allows for an erection in response to sexual stimulation.
Elevated levels of cGMP lead to smooth muscle relaxation and increased blood flow to the penis, facilitating the erection process. Viagra works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which results in an increase in the levels of cyclic guanosine monophosphate (cGMP). The mechanism of action of Viagra involves the enhancement of nitric oxide (NO) effects in the corpus cavernosum of the penis. It is important to note that sexual stimulation is required for Viagra to be effective, as it does not initiate an erection but rather makes it easier to develop and maintain one when there is arousal.
This leads to prolonged blood flow and, consequently, a sustained erection. Viagra works by inhibiting the action of PDE5, thereby increasing the levels of cGMP in the corpus cavernosum. PDE5 breaks down cGMP, thus regulating blood flow and causing the erection to subside. However, it is important to note that Viagra does not increase sexual desire; it only helps to maintain an erection when sexual stimulation occurs. Viagra is administered orally, typically in dosages ranging from 25 mg to 100 mg.
It is advised to take the medication about one hour before sexual activity, and its effects can last up to four hours. More severe reactions, though rare, can include priapism (a painful erection lasting longer than four hours), sudden hearing loss, and myocardial infarction, especially in those with pre-existing heart conditions. The most common include headaches, flushing, indigestion, nasal congestion, and impaired vision. Despite its benefits, Viagra is not without side effects.
