    Background: The cardiovascular effects of sildenafil (Viagra), a selective inhibitor of phosphodiesterase type 5 (PDE5), have been extensively studied. However, its effect on human retinal arteries and veins has not yet been investigated.

Methods: Sildenafil 50 mg was administered to 10 healthy subjects (male:female = 4:6; mean age 31 (SD 6) years). The diameters of retinal arteries and veins were measured by means of a retinal vessel analyser (RVA) immediately before and at 30, 60, 90, and 120 minutes after sildenafil uptake. Blood pressure, heart rate, and intraocular pressure were monitored in parallel.

The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete intercourse). Its use is now one of the standard treatments for erectile dysfunction, including for men with diabetes mellitus. Rare but serious adverse effects found through postmarketing surveillance include prolonged erections, severe low blood pressure, myocardial infarction (heart attack), ventricular arrhythmias, stroke, increased intraocular pressure, and sudden hearing loss. Care should be exercised by people who are also taking protease inhibitors for the treatment of HIV infection. Protease inhibitors inhibit the metabolism of sildenafil, effectively multiplying the plasma levels of sildenafil, increasing the incidence and severity of side effects. Those using protease inhibitors are recommended to limit their use of sildenafil to no more than one 25 mg dose every 48 hours. blocker (typically prescribed for hypertension or for urologic conditions, such as benign prostatic hypertrophy) at the same time may lead to low blood pressure, but this effect does not occur if they are taken at least 4 hours apart.

    Cialis requires more caution when mixed with alcohol. Cialis, as you probably know, has a different formulation than Levitra and Viagra, which allows it to work for far longer. You have to be a bit more careful combining alcohol with Cialis than you would with Viagra, Levitra, or Staxyn. Tadalafil, the active ingredient in Cialis, can lower your blood pressure. Drinking alcohol can further lower your blood pressure, and if your blood pressure drops too much, you can experience light-headedness, fainting, headache, and heart palpitations – not the best conditions for romance. In fact, combining Cialis with alcohol can result in something called “postural hypotension,” which is a sudden drop in blood pressure when you stand up from a lying or sitting position that can cause you to faint. Bear in mind that the half-life of Cialis is around 18 hours, compared to four to six hours for Viagra, Levitra, and Staxyn. For many men, drinking alcohol can relieve some of the anxiety that naturally goes along with meeting potential new partners or dating, which can be good for social interaction to some extent. That’s why it’s marketed as the “Weekend Pill.” Therefore, when you take Cialis, you need to avoid drinking for longer than you would with other erectile dysfunction medications? Too much alcohol – and the exact amount differs from person to person – can not only decrease sexual desire, it can also make sexual activity difficult to impossible until the alcohol has had a chance to exit the system.
