Viagra is known to treat impotence, in fact, it was first developed as a treatment for angina in medical trials. Unfortunately, early clinical trials were not positive. To have the right effect the drug had to be taken three times a day and it gave some of the patients muscle aches. It was also found to interact with nitrates the standard treatment for angina, which resulted in an unsafe drop in patients’ blood pressure. Viagra works by binding to an enzyme called phosphodiesterase. Viagra binding to the enzyme prevents it from converting the chemical cyclic guanosine monophosphate abbreviated cGMP into guanosine triphosphate. However, the drug will not give patients an erection without sexual stimulation. When a man becomes aroused the brain sends a signal to the cells in the penis to release nitric oxide, which turns on the production of cGMP. Without the stimulation to produce nitric oxide, there is no cGMP build-up and no erection. All forms of the drug are sold as solidgel capsules and in doses up to 100 mg. Under the UK decision, the active ingredient tadalafil is currently protected by a patent which is not due to expire until 2016. The patent prevents any company from manufacturing generic Cialis.

As with all prescription medications, it’s important that you check with the doctor before starting your course of treatment to ensure that it’s the right one for you.

Viagra 50mg tablets for the first time. His prescription drugs did not work for him straight - it simply doesn't want to wait for an erection to develop, so I talked to my doctor he/she could check if Viagra was working and whether there is a physical problem. I know it's not normal and is probably taking a higher dose than Viagra which I would think is likely to be having a 5mg dosage. I use viagra before sex and usually within a half hour it is starting to work. This actually works well as my wife likes foreplay and petting to build up to intercourse. The effect of the viagra lasts for a couple of hours if needed. Why would you possibly want to do that?. Despite the different reasons all of the meds have been antidepressant. Now I'm on trazadone. I am a bit concerned about the whole erection idea. Have you ever experiended this side effect while you were completely awake and alert? Or does this only happens as you sleep?. The result was remarkable for me at 75mg my doctor prescribed 100mg tabs and told me to either cut them in half, or increase the dose to 75 or 100 if needed for sleep - which is what this drug is now usually prescribed for.
