This page lists polysubstance combinations that are entheogenic, recreational, or off-label indicated use of pharmaceuticals.
The detection window for body hair cannabis testing will be longer, because body hair grows slower than head hair and distorts the detection timeframe. Hair drug testing measures the marijuana parent metabolite embedded inside the hairshaft and eliminates external contamination as a source of a positive result.
The effect of grapefruit juice with regard to drug absorption was originally discovered in 1989. The first published report on grapefruit drug interactions was in 1991 in the Lancet entitled "Interactions of Citrus Juices with Felodipine and Nifedipine", and was the first reported food-drug interaction clinically. The effects of grapefruit last ...
Warfarin (actually the S-warfarin enantiomer) is a specific probe for CYP2C9. The '+ 1' refers to the vitamin K that is given together with the warfarin to prevent any anticoagulant effect. The Cooperstown cocktail and the Cooperstown 5 + 1 cocktail are powerful tools for investigating the activity of important drug metabolising enzymes.
Marijuana's official designation as a Schedule 1 drug — something with "no accepted medical use" — means it is pretty tough to study.. Yet both a growing body of research and numerous ...
The Duquenois reagent is used in the Rapid Modified Duquenois–Levine test (also known as the simple Rapid Duquenois Test), which is an established screening test for the presence of cannabis. The test was initially developed in the 1930s by the French medical biochemist Pierre Duquénois (1904–1986) and was adopted in the 1950s by the ...
Important drug interactions are rare. [38] [39] However, the most significant major drug interaction concern is the decreased activation of clopidogrel when taken together with omeprazole. [40] Although still controversial, [41] this may increase the risk of stroke or heart attack in people taking clopidogrel to prevent these events.
