Sildenafil Alcohol

Drugs that may interact with nitrates include alcohol, alteplase, aspirin, beta-blockers, calcium channel blockers, dihydroergotamine, heparin, nondepolarizing muscle relaxants, phenothiazines, phosphodiesterase inhibitors (eg, sildenafil, tadalafil, vardenafil), and vasodilators. 

A 68-year-old man with alcoholic cirrhosis and small esophageal varices (degree of severity classified as Child 1) started bleeding after taking sildenafil 25 mg for the first time (28). 

Although not strictly alternative medicine, the incubation of a West Indian centipede in alcohol for several weeks is alleged to result in the formation of a compound that has effectiveness in erectile dysfunction. If this compound is similar to sildenafil and inhibits phosphodiesterases, it would be contraindicated in a patient who is being treated with... 

Tadalafil is different in structure from both sildenafil and vardenafil. It is rapidly absorbed and peaks in concentration (378 pg/L after a 20-mg dose) after 2 hours, displaying a long half-life of 17.5 hours. It also is metabolized by the liver (CYP3A4). Notably, its pharmacokinetics is not clinically influenced by alcohol or food intake or by factors such as diabetes or impaired hepatic or renal function (13). 

Sildenafil, tadalafll and vardenafil do not usually alter the effects of alcohol on blood pressure, although postural hypotension has been seen in some subjects given tadalafll and alcohol, and headache and flushing has been reported in one patient taking sildena-... 

Drugs employed have sedative or hypnotic properties with a rapid onset and induce memory loss during the period when the drug is active. The most-prevalent drugs detected, apart from alcohol, are the benzodiazepines and h5 notics (zolpidem and zopiclone). A wide range of other drugs, such as GHB, ketamine, sildenafil, methadone, buprenorphine, diphenhydramine, trimeprazine, acepromazine, thiopental, pentobarb, doxylamine, and cyamemazine, have also been reported in DFC cases.
