Mequinol is a common active ingredient in topical drugs used for skin depigmentation. As a topical drug mequinol is often mixed with tretinoin, a topical retinoid. A common formulation for this drug is an ethanolic solution of 2% mequinol and 0.01% tretinoin by mass. [1] Dermatologists commonly prescribe the drug to treat liver spots.
Drug nomenclature is the systematic naming of drugs, especially pharmaceutical drugs.In the majority of circumstances, drugs have 3 types of names: chemical names, the most important of which is the IUPAC name; generic or nonproprietary names, the most important of which are international nonproprietary names (INNs); and trade names, which are brand names.

Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...
MOPPP use is infrequent when compared to other amphetamines or stimulants used recreationally, such as meth, cocaine, or speed.It first arose as a designer drug in Germany in the late 1990s and early 2000s, [1] [2] [3] along with a number of other derivatives but never gained the international popularity [4] [5] that other drugs in its family of pyrrolidinophenone derivatives had (such as α ...
Any chemical substance with biological activity may be considered a drug. This list categorises drugs alphabetically and also by other categorisations. This multi-page article lists pharmaceutical drugs alphabetically by name. Many drugs have more than one name and, therefore, the same drug may be listed more than once.
See the list of steroid metabolism modulators instead for steroid/sterol-specific CYP450s, including: CYP7A1 (cholesterol 7α-hydroxylase) CYP7B1 (25-hydroxycholesterol 7α-hydroxylase) CYP8B1 (sterol 12α-hydroxylase) CYP11A1 (cholesterol side-chain cleavage enzyme; P450scc) CYP11B1 (steroid 11β-hydroxylase) CYP11B2 (aldosterone synthase)
In the simplest example oxygen can be used as it exists naturally in its triplet state (i.e. it is a diradical). This is referred to as air inhibition and is a diffusion-controlled reaction with rates typically in the order of 10 7 –10 9 mol −1 s −1 , [ 3 ] the resulting peroxy radicals (ROO•) are less reactive towards polymerisation.
para-Methoxyfentanyl or p-methoxyfentanyl or 4-methoxyfentanyl is a potent short-acting synthetic opioid analgesic drug. It is an analog of fentanyl , with similar effects but slightly lower potency.
