About Viagra
Viagra is a prescription medicine used to treat erectile dysfunction (ED) in men. It belongs to a group of medicines known as phosphodiesterase type 5 (PDE 5) inhibitors. Viagra works by increasing blood flow to the penis, which helps men achieve and maintain an erection.
Viagra may be prescribed to men who have certain heart conditions, such as heart failure or low blood pressure. It may also be used to treat pulmonary arterial hypertension (PAH).
Men with erectile dysfunction should consult their doctor before using Viagra. Erectile dysfunction can be caused by various factors, including underlying health conditions, but it's important to note that it's normal to experience erectile dysfunction once or twice a week.
Viagra works by relaxing the blood vessels in the penis, thereby increasing blood flow. This helps men achieve and maintain an erection.
The active ingredient in Viagra is sildenafil, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Viagra works by inhibiting PDE5, which is an enzyme that breaks down chemicals in the body that cause erection problems. This allows more blood to flow into the penis, which helps men achieve and maintain an erection.
The FDA has approved Viagra for use in men only, as it is safe and effective for use.
Benefits of Viagra:

It's a little embarrassing to tell people, but it's not that bad after the first few weeks of sex.
The good news is that Viagra can be bought online from all over the UK. This is because a drug called sildenafil, which is sold under the brand name Viagra, is also sold over-the-counter.
It's one of the most popular treatments for erectile dysfunction, and is so effective that most men who use it suffer from occasional trouble getting an erection that lasts indefinitely.
It works by helping the arteries that supply the penis to fill with blood, which helps to keep it erect over time. It also increases the number of blood vessels that carry oxygen and nutrients to the penis during sexual activity.
This increases the chances of successful sexual intercourse.
Sildenafil is only available as a tablet and is often sold under the brand name Viagra. It's also available in generic form, but the active ingredient is the same in both.
When you buy Viagra from a pharmacy, you won't have to worry about getting it from a supermarket. There's an online search feature in the UK called, and you can use it to find you.
You can buy the tablets from your local pharmacy, but you can also get the generic sildenafil online from a UK pharmacy, and you won't have to think about it.

Many men take sildenafil to have a harder or more satisfying sexual experience. Some men take it as a daily tablet, while others take it as a pill, usually taken about an hour before sexual activity.
It's important to note that Viagra and sildenafil should only be taken on an empty stomach, and that the effectiveness of both medications will only be seen if you're sexually aroused.
Some men take it on an as-needed basis. This is because it's not recommended for use on an empty stomach, and it's not effective for continuous erection of the penis. It should only be used when it's necessary.
You can also ask your doctor or pharmacist to advise you on how to take sildenafil.
Sildenafil is a prescription medicine, so your doctor or pharmacist will have you on an empty stomach and a light meal. You can take sildenafil with or without food, but it should be taken at a fixed time each day.

If you have any side effects, such as back pain or muscle aches, or if you develop a painful erection, you should see a doctor immediately.
Background:
Many men are reluctant to use generic drugs because of fear of adverse side effects. The World Health Organization (WHO) guidelines recommend that men with erectile dysfunction should avoid sexual activity. However, there are no studies on the safety of Viagra or other sildenafil citrate products.
A randomised controlled trial is needed to confirm the safety of sildenafil citrate products.
Methods
In this randomised controlled trial, 100 men aged 18-64 years, with a mean age of 56.3 years were recruited from nine participating centres in New Zealand. Patients included in the study were on stable doses of sildenafil citrate (25 mg, 50 mg, or 100 mg daily) or a placebo (no drug). Patients had moderate to severe cardiovascular disease or uncontrolled hypertension, or those taking nitrates for angina. Patients were randomly assigned to receive either the active substance sildenafil or a placebo or their usual dose of the drug. Patients were advised to take sildenafil as needed at least 1 hour before sexual intercourse. If patients were unable to swallow the tablets, they were advised to contact their healthcare provider or a pharmacist for further advice.
Results
Of the 100 participants, 60 (74.5%) reported that their ED symptoms had resolved with the usual dose of sildenafil citrate. The median time to resolution of ED symptoms was 4.5 days, and there was no significant difference in the mean age of the participants, age range, or duration of erectile dysfunction between the two groups. The median duration of sildenafil use was 1.5 years in the placebo group and 1.5 years in the sildenafil-treated group (Table 1).
Conclusion
Sildenafil citrate has a low incidence of adverse side effects in patients with erectile dysfunction. However, there is little information on the safety of sildenafil citrate products.

A PDE-5 inhibitor is a PDE-5 inhibitor which increases the levels of a phosphodiesterase enzyme which improves blood flow to the penis during sexual stimulation.

4.MUMBAI: The prime minister of a country whose president has already signed a deal with India's drug companies to stop the sale of Viagra, Dr Mahamuddin said Tuesday.
The drug company that has been linked to the deaths of more than 300 people was in the country's sex scandal after it said the ministry had "severely influenced the country's medicine supply chain and increased pressure on companies to stop sales."
The drug maker, Ranbaxy, said the deal was the latest in a string of public-health deals between the government and drug companies in the face of rising scrutiny over pricing of drugs, including erectile dysfunction treatments like Viagra and Cialis.
The deal will also allow for a new mechanism by the government to prevent the companies from marketing Viagra to doctors for marketing purposes, including for medical use.
Dr Mahamuddin said a similar measure had been agreed with the government last year. He said the deal would now include the addition of an additional incentive for doctors to give patients information about their treatment, and would also make it easier for the drug companies to advertise and market their medicines in the public domain.
He said the government had reached an agreement with India's drug companies that the drug makers could not take advantage of the deal.
"The government has reached an agreement with India's drug companies that the drug makers could not take advantage of the deal," Dr Mahamuddin said.
He said the government had not given any reason to believe that the deal would affect the number of drugmakers that would be involved in the drug industry.
In a statement on Tuesday, the government said that all companies operating in the drug industry had signed a "disclosure agreement" and would be "considered for inclusion in the government's list of eligible persons by the end of the year."
It also said the government had granted approval to two companies to begin selling medicines on the government's list of "qualified persons."
The government has yet to comment on whether other companies would be included on the list of qualified persons.
The drug companies that have been linked to deaths of more than 300 people have yet to be approved to market medicines that are being sold in the country, a government ministry said.The ministry said that the government had agreed to a six-month process that would be put in place by April 1, to ensure that all companies that have signed a "disclosure agreement" would be included.
The ministry will also work with the companies to "coordinate and establish a process for the approval and distribution of products to be marketed in the country," it said.
