Viagra- Unstoppable Demand
makes Viagra stand out? What is so great about Viagra, that other brands/drugs in its class cannot even hold a candle, let alone a light to it. Viagra was the first drug to be launched in a forgotten segment - men with impotence or erectile dysfunction. For years, nobody actually even thought that there was a huge market out there for drugs to treat erectile dysfunction. Erectile dysfunction is defined as the inability to ensure or ensure an erection for satisfactory sexual intercourse. For years, scientists had tried to understand the complex mechanisms involved there. The process of having an erection appeared to be deceptively simple. It just involved three steps - Firstly sexual arousal, secondly nerve signals from the brain that act on the blood vessels involved and thirdly the blood vessels dilate and this increased blood flow causes an increase in hydraulic pressure. Thus causing an erection. The best way to ensure an erection was to work on the control of any of the steps involved. This is simpler said than done. The reason - the intermediate enzymes and chemicals are common to all parts of the body. E.g. acetylcholine - which works throughout the body . Therefore any drug acting on it can hamper it's function elsewhere, like in the heart. Also the exact mechanism of certain pathways was not exactly clear. Most importantly for any erection, sexual arousal was so important. The No one in the pharmaceutical industry had ever dreamt of the kind of success enjoyed by Viagra. Today this blockbuster drug launched by Pfizer is used by millions of men all over the world and every day,to the utter dismay of its's competitors - many more are joining their ranks. Why is that so ? What level of sexual arousal differs from person to person and is very subjective. There were patients who were depressed or had other psychiatric problems. Thus researchers found it very difficult to find a drug that can make an erection. Though 150 million men suffer from erectile dysfunction, less than 5% ever went to the doctor for it. For those who ventured to open their mouth, found it very embarrassing and humiliating. They were advised counseling (for heavens sake, they had already talked enough to their wife, before meeting the doctor) and/or penile implant/pumps which are very painful. Since most of them, were anyway depressed, they were prescribed anti-depressants or anxiety relieving medicines. An effort was made to sweep this very important medical condition under the carpet by all involved, the patient, his wife and the doctor. That was until the year 1998. The Sixties(1960s) launched the first sex revolution. This was among the young people. The launch of Viagra in 1998 launched the second sex revolution. This was among the older population. Especially those over 40 years old. A whole new generation in their 50s,60s and even 70s felt sexually liberated. Studies have shown that almost 40% of men above 40 years suffer some form of erectile dysfunction. For long the lifestyle drugs what were known till then, were those in heart disease and diabetes. Viagra added another segment - sexual lifestyle drugs. Suddenly a whole new market segment was born. What did Viagra do to erectile dysfunction that was so different?. Viagra contains sildenafil citrate, which acts to block the enzyme Phosphodiasterase-5 (PDE-5), which is responsible for degrading the enzyme cyclic Guanosine Monophosphate(cGMP) which ensures dilation of the blood vessels needed for sustaining an erection. It's action is so strong that Viagra can ensure a good erection for upto 4 hours after taking it. What more, any man with erectile dysfunction, who did not have any cardiac or renal problems would have almost no side-effects on taking it. In addition to that Viagra was extremely fast acting - It just took 15 minutes to act in the presence of sexual arousal. These benefits really show the potency of Viagra and make it stand out. Despite the launch of other drugs, Viagra is still the first drug to be prescribed to any new patient with erectile dysfunction. Other drugs are only prescribed if Viagra does not work in the presence of other medical complications. Very often patients do not reveal all their medical conditions, their enthusiasm to try out a new drug. In the right patient, Viagra works like no other. Today, patients don't even need to make an embarrassing visit to the doctor to get a prescription for Viagra. They can just buy Viagra through the internet. They only have to fill an online form and a prescription is generated. They can conveniently ensure privacy in ordering and delivery of Viagra. What more online sites offer, huge discounts on bulk or monthly purchases. These sites also offer links to Viagra information, which most local pharmacies would never bother to give. All these benefits drive the unstoppable, phenomenal demand for Viagra. If you are reading this and have erectile dysfunction or a spouse of the same, don't wait, just go for the drug that used safely everyday by millions of men all over the world. Go for Viagra.
