Viagra (sildenafil) is used to treat erectile dysfunction. Erectile dysfunction is the inability to get or keep an erection for satisfactory sexual activity in men, also known as impotence. Sildenafil belongs to a class of medications called phosphodiesterase type5 (PDE5) inhibitors. Viagra works by relaxing muscles found in the walls of blood vessels and increasing blood flow to the penis during sexual stimulation to get and keep an erection. Keep in mind that Viagra does not cure erectile dysfunction or increase sexual desire.
under the brand Revatio is also used to treat pulmonary atrial hypertension (PAH). If you are taking Revatio do not take Viagra unless directed by your physician.
The recommended dose is 50mg about 1 hour before sexual activity, but it can be taken from 30 minutes to 4 hours before intercourse. The maximum daily dosage is once per day, with or without food. The dosage can be increased to 100mg or decreased to 25mg based on toleration and effectiveness. Viagra 100mg are available in KamaHealth.

New research shows that men taking the erectile dysfunction drug Viagra have less sex at all.
Researchers at New York University School of Medicine and the University of Texas Southwestern Medical Center in Dallas found that those taking the drug — also known as the “little blue pill” — were more likely to suffer from premature ejaculation.
And while the results were promising, the drug’s side effects are not the only worry.
“I don’t think it’s safe or effective for most men,” said Dr. Steven Nissen, a urologist and assistant professor at New York’s St. Luke’s Medical School. “Viagra is a very safe and effective drug.”
Viagra and the other erectile dysfunction drugs also have the potential to affect brain chemistry, he said.
“Our results indicate that Viagra will increase the amount of serotonin in the brain, and that could be a key cause of premature ejaculation,” Nissen said.
But the study doesn’t test the drug’s efficacy in men with ED, he said.
“The drug is safe and effective in men with ED,” Nissen said. “We know that it may have other benefits, and it’s important to use this therapy with caution.”
Some men take the drug just for the little blue pill. Nissen said other medications, such as Viagra, could affect how Viagra works.
Nissen said some men may be taking other drugs to treat other conditions. He said he hasn’t had problems with the drug himself.
“It’s not as bad as the Viagra,” Nissen said.
But it’s important to note that men taking other medications, including blood pressure drugs, may be more susceptible to side effects.
The research, published in the American Journal of Obstetrics and Gynecology, does not prove that Viagra and other erectile dysfunction drugs work for all men.
But Nissen said men who take Viagra and other ED medications can experience less sex at work.
“We know that, on average, men who take the Viagra tend to be less sexually active,” Nissen said.
For that reason, it’s important for doctors to monitor men who take the medication regularly.
Nissen said he’s also concerned about the effects of the drug on a woman’s sex life. But for men taking other medications, including blood pressure drugs and testosterone, Nissen said there are other ways to treat the side effects.
“If a man has trouble getting or keeping an erection, the doctor may recommend taking an alpha-blocker,” Nissen said. “That’s what the ED drug is for.”
While the study wasn’t definitive, Nissen said his research is still being done. He also wasn’t surprised that Viagra and other ED drugs have a lower chance of causing problems for women.
“I’m not surprised that a little blue pill, like Viagra, can cause problems for women,” Nissen said.
In fact, the study found that men taking the erectile dysfunction drug Viagra — which is sold under the brand name Revatio — were more likely to suffer from problems.
“I think what they found is that men who take Viagra, they tend to get less sex at work,” Nissen said.
In addition, men who take erectile dysfunction drugs for two or more years can have problems that can last for a month or two.
A study in the Journal of Sexual Medicine found that men who took the drug for two or more years were more likely to experience sexual dysfunction.
Nissen said doctors need to be cautious when prescribing Viagra or other ED drugs.

Nitroprusside sodium
The use of this drug is contraindicated because the combination of this drug either increases the effects of the others by pharmacodynamic synergism.
Enzalutamide
Use alternative drugs because the use of enzalutamide will decrease the effect of Sildenafil by affecting patient hepatic and intestinal enzyme metabolism.
Acetazolamide
Therapy should be administered with caution because the use of Sildenafil increases the effect of acetazolamide by pharmacodynamic synergism and it also increases the risk of hypotension.
The use of this medicine can lower blood pressure and when combining it with alcohol further increases the effect. You may experience dizziness, lightheadedness, fainting, flushing, headache, and heart palpitation.

Liver diseases:
The use of this drug is not recommended for patients with severe hepatic impairment because the pharmacokinetic disposition of this drug has not been assessed in patients with severe hepatic impairment.
In PDE5 inhibitor patients with severe renal impairment, the hepatic and intestinal enzyme levels may be reduced because the plasma clearance of this drug is decreased.
No dosage adjustment is recommended in patients with severe hepatic impairment. Therapy should be administered with caution in these patients.
The use of this medicine can reduce the benefits of a high-fat meal because it inhibits the metabolism of this drug by Incidence Factors.
The use of phosphodiesterase-5 enzyme inhibitors is not recommended for patients with cardiovascular disease. A doctor should consider the vasodilatory effects of this drug and whether Niaspin, nitrate, glyceryl monostearate, isosorbide dinitrate, or nitroglycerin may interact.
Therapy should be administered with caution in patients with a severe renal impairment or in patients with a severe renal function which is also in the range of renal function of patients with severe hepatic impairment.
No dosage adjustment is recommended in patients with a severe renal impairment or with a renal dialysis.
You have a drug-food intolerance. People who have a food allergic reaction, a hypersensitivity type reaction, or anaphylactoid reactions have an increased risk of developing this problem.
