Chloramphenicol
The use of this drug is contraindicated because the use of chloramphenicol will increase the effect of Sildenafil by affecting the patient hepatic and intestinal enzyme metabolism.
Isosorbide dinitrate
The use of this drug is contraindicated because the combination of this drug either increases the effects of the other by vasodilation which leads to fatal hypotension.
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. Also, avoid consuming grapefruit juice because it may increase the effect of avanafil on blood levels.
Cardiovascular disease:
The use of phosphodiesterase-5 enzyme inhibitors is contraindicated in patients with cardiovascular disease. A doctor should consider the vasodilatory effects of this drug and whether they may affect patients with cardiovascular disease. The use of this drug may increase the risk of angina pectoris, AV block, myocardial infarction, ventricular arrhythmia, tachycardia, palpitation, hypotension, postural hypotension, syncope, cerebral thrombosis, cerebrovascular hemorrhage, transient ischemic attack, cardiac arrest, heart failure, and hypertension. These events can occur during or after sexual activity.
Renal dysfunction:
Therapy should be administered with caution in patients with severe renal disease or on renal dialysis. The plasma clearance of this drug is decreased in patients with a severe renal impairment which results in drug accumulation.
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.
J Pharm Der Physiol. 2007;7:87.Competitive chemistryLiver disease: a competitive reaction of organic anions and cations with organic acids and anions is described in the literature. The reaction is described in greater detail in the article by Liu et al. The reaction is based on the reaction of 1-(2-chloropropyl)benzotriazole with cetyl- and dodecyl-guanlayer. The addition of an organic acid to the reaction results in the formation of a nucleophilic group and the addition of an isoole groups results in the formation of a cetyl- and dodecyl-benzotriazole group. The addition of an anion to the reaction results in the formation of a benzonylbenzotriazole group. The addition of an organic acid to the reaction results in the formation of a benzonylbenzotriazole group. The reaction is stopped by the addition of an amino group and by the addition of an alcohol group. The products are then separated by thin layer diffusion.The following table summarizes the method of the paper by Liu et al., published in: a competitive reaction of organic anions and cations with organic acids and an anion. The reaction is based on the reaction of 1-(2-chloropropyl)benzotriazole with a cetyl- and dodecyl-benzotriazole group.

WASHINGTON (CNN) --The Food and Drug Administration has approved the use of prescription-strength Viagra -- the active ingredient in the erectile dysfunction drug Viagra -- as a potential treatment for a male-pattern disorder.
The drug, developed by Eli Lilly and Company, has been linked to a number of adverse events in patients with sexual problems.
A study found that men who took Viagra had a greater risk of impotence than those who did not take the drug.
Eli Lilly said that the use of Viagra is a "comprehensive, FDA-approved indication for the treatment of erectile dysfunction."
Viagra was originally approved for use in men only. The company had been evaluating the potential benefits of the drug in women since 1998.
Although it has been prescribed to millions of patients, Viagra has been associated with sexual side effects including flushing, nausea, headache, dizziness, and erectile dysfunction.
The drug is not approved for use in children.
Viagra was developed as an orally disintegrating tablet for use in children.
Pfizer said in a statement that the drug's safety and efficacy have not been established in children.
"Pfizer believes that Viagra is not associated with an increased risk of death or cardiovascular disease in children and adolescents," said company president and CEO Daniel Williams. "While it is not yet known whether the safety and effectiveness of this drug in children and adolescents have been established, we are disappointed that it has not been approved for use in children."
In 2012, the Food and Drug Administration gave Pfizer the green light to begin marketing the drug for the treatment of sexual dysfunction. The agency did not approve the use of Viagra in children.
A study published in theJournal of Sexual Medicinefound that men who took Viagra had a greater likelihood of impotence than men who did not take the drug.
Pfizer said that the study was based on data from 3,979 patients who received Viagra. Viagra was available for purchase in 50 mg and 100 mg tablets.
Viagra is sold by Pfizer under the brand name Sildenafil.
Pfizer did not return a request for comment on whether Viagra would be approved for use in children.
In 2003, the company said, the FDA had granted approval to marketing Viagra in the U. S. under the brand name Cialis.
Pfizer has not yet approved Viagra for use in children.
