Routine use of drugs like Viagra is associated with an increased risk of developing several types of eye problems that can lead to sudden vision loss ...
Erectile dysfunction medications like Cialis and Viagra increase the effects of a chemical called nitric oxide to relax penile muscles responsible for erections. Relaxation of muscles allows blood to flow more freely into the penis. However, ED drugs won’t give men “instant” erections. Sexual stimulation is necessary to achieve an erection after taking ED medications.2
Call your doctor right away if you take one of these medications and have a prolonged erection that lasts 4 hours or longer. This condition may cause permanent impotence if not treated.
The Prostate Cancer Prevention Trial was a landmark study by Thompson et al that prospectively assessed the time to developing CVD after the diagnosis of ED. There were 4247 men with no ED at study entry; 2420 developed incident ED (defined as the first report of ED of any grade) over 5 years. Those men that developed ED had a 1.45-fold higher probability of experiencing a CV event compared with men who did not develop ED.27
As with most other organ system in the human body, changes and loss of function is normal consequence of the ageing process. This is also true of the endocrine system, specifically the levels of testosterone production from the Leydig cells of the testicle. Accompanying the decrease in testosterone is a decrease in erections which also has a component in decrease in the blood supply to the penis making erection not as frequent and not as rigid compared with a young man’s erectile function. Although these changes are in itself not life threatening, they can impact a man’s relationship with his partner, and also ED may be a harbinger of other undiagnosed conditions such as coronary artery disease (CAD), hypercholesterolaemia or diabetes mellitus.6

However, since higher plasma levels may increase the incidence of adverse reactions, a starting dose of 25 mg should be considered in older subjects due to the higher systemic exposure [see DOSAGE AND ADMINISTRATION].
Hearing: Cases of sudden decrease or loss of hearing have been reported postmarketing in temporal association with the use of PDE5 inhibitors, including VIAGRA. In some of the cases, medical conditions and other factors were reported that may have also played a role in the otologic adverse events. In many cases, medical follow-up information was limited. It is not possible to determine whether these reported events are related directly to the use of VIAGRA, to the patient's underlying risk factors for hearing loss, a combination of these factors, or to other factors [see WARNINGS AND PRECAUTIONS and PATIENT INFORMATION].
Inhibition of the PDE-5 enzyme increases the concentration of a signaling molecule known as cyclic guanosine monophosphate (cGMP), which leads to relaxation of vascular smooth muscles, dilation of blood vessels, and improved blood flow.
Although ED is commonly seen in older men, it is not a natural part of aging. Older men may need more sexual stimulation, such as touching or stroking, to achieve an erection, or they may need longer periods between two erections. Older men in good health, however, should be able to get an erection sufficient for intercourse.
