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

The first major global pharmaceutical company to announce its plans to develop a new anti-impotence drug to combat erectile dysfunction is Australia's leading erectile dysfunction (ED) medicine Viagra.
Viagra, a well-known ED treatment, is the latest product to make the pharmaceutical industry realise that Viagra is not the answer they want.
The company has recently launched a new treatment for ED, a treatment for a rare genetic condition known as retinitis pigmentosa, and has recently launched a new treatment to treat a rare form of angina in the late 1990s.
But the company has failed to make a strong case for it to launch a new product for ED.
Viagra's patent for the treatment was expiring in 2014 and will likely be challenged by the patent protecting its rights to other ED treatments.
The patent for Viagra will expire in November 2015, when generic competition hits the market.
It's a move that will mean the product will be much less expensive than a cheaper generic version.
Viagra is the best-selling medication on the planet, and sales of the drug have been growing at a rapid rate since it was introduced in 1998.
But sales of Viagra are already slowing.
In a statement, the company said: "We are pleased with the results of the Viagra launch and believe it will continue to deliver value to our patients.
"We are committed to working closely with pharmaceutical manufacturers to develop new treatments that patients will benefit from using Viagra and we remain confident that the launch of a new treatment for erectile dysfunction will be successful."
In August, the company announced that it was launching a new product in the UK calledErectile Dysfunction, which will treat men with erectile dysfunction and the underlying condition impotence.
Erectile dysfunction is a condition in which a man has difficulty getting or keeping an erection long enough for sex. It is usually caused by physical or psychological factors.
The underlying condition is often genetic, and is thought to be caused by the body's natural sensitivity to nitric oxide.
Viagra and the treatment are both treatments for impotence.
Dr Peter Reid, Pfizer's medical director, said: "Viagra is an effective treatment for ED, but it is still a new one.
"The patent for Viagra is still valid, but it is time to take action.
"Our hope is that we can launch a new treatment for erectile dysfunction in the spring of 2015 and have it ready for launch in the summer of 2015."
Viagra is a treatment for erectile dysfunction, which can affect sexual performance and quality of life.
The drug is also used to treat pulmonary arterial hypertension.
In a statement, Pfizer said: "We are pleased with the results of the Viagra launch and believe it will continue to deliver value to our patients.
"Pfizer's announcement that it is working closely with pharmaceutical manufacturers to develop a treatment for erectile dysfunction in the US and Europe will be the first to be approved.
"The company also is committed to working closely with pharmaceutical manufacturers to develop new treatments that patients will benefit from using Viagra and we remain confident that the launch of a new treatment for erectile dysfunction will be successful."
Viagra, which is currently under patent in Australia, has already been available to Australian patients for more than a decade.
In 2013, Pfizer acquired the rights to the drug from AstraZeneca.
In 2008, AstraZeneca acquired the rights to the treatment from Pfizer.
The drug works by blocking an enzyme in the body that causes the blood vessels to narrow and the heart to beat faster, thus increasing blood flow to the penis and causing an erection.
In a separate transaction, Pfizer has acquired rights to the erectile dysfunction treatment from Pfizer.
In 2015, Pfizer's patent for the treatment expired in the UK, and sales of the drug have already been growing at a rapid rate.
In July, the company announced it was seeking to launch a new treatment for erectile dysfunction in the US.
A drug that treats erectile dysfunction can be prescribed in one of two ways:
A prescription is only available through a doctor's prescription.
Men in the U. S. are getting a lot more information from the Food and Drug Administration about the treatment of erectile dysfunction (ED). The FDA has issued an advisory to treat erectile dysfunction and the other symptoms of the condition, such as reduced sex drive, sexual inability, and sexual difficulty.
An FDA advisory is expected to be posted at the end of September, but there are many other studies that may offer the first answers.
The FDA will continue to closely monitor the safety of the drug.
One study that has been completed by the FDA has found that it can cause sexual problems in men who take Viagra. In one study, one in three men taking the drug reported sexual problems.
The study, published in theJournal of Sexual Medicine, involved more than 50,000 men, most of whom had tried Viagra before.
The results of the study did not reach the FDA, but several other studies have shown the drug can cause erectile dysfunction.
Men who have problems with sexual ability should be advised of their options if they are struggling to get an erection, and they should be advised to talk to their doctor about other treatments for erectile dysfunction.
The drug, called Viagra, is taken by men who are 50 or older and have difficulty getting an erection. Men who have trouble getting an erection will not be prescribed the drug, but may have other options.
The drug is not approved for use by women and is not recommended for use in children under 18 years of age.
In the United States, the Food and Drug Administration (FDA) will continue to monitor the safety of the drug. The drug is only approved to treat ED, but it has been suggested for use in children under 18 years of age.
In the meantime, the public can report unsafe drugs on the FDA Web site.
