One, and only one, lone pair of electrons from each heteroatom in the ring is part of the aromatic bonding in an azole. Names of azoles maintain the prefix upon reduction (e.g., pyrazoline, pyrazolidine). The numbering of ring atoms in azoles starts with the heteroatom that is not part of a double bond, and then proceeds towards the other ...
For example, the azole antifungals such as ketoconazole or itraconazole can be both substrates and inhibitors of the P-glycoprotein, which (among other functions) excretes toxins and drugs into the intestines. [34] Azole antifungals are also both substrates and inhibitors of the cytochrome P450 family CYP3A4, [34] causing increased ...
1,2,4-Oxadiazole, 1,2,5-oxadiazole, and 1,3,4-oxadiazole are all known and appear in a variety of pharmaceutical drugs including raltegravir, butalamine, fasiplon, oxolamine, and pleconaril. The 1,2,3-isomer is unstable and ring-opens to form the diazo ketone tautomer ; [ 2 ] however, it does exist within the unusual sydnone motif.
In July 2013, the US Food and Drug Administration (FDA) issued a warning that taking ketoconazole by mouth can cause severe liver injuries and adrenal gland problems: adrenal insufficiency and worsening of other related to the gland conditions. [13] It recommends oral tablets should not be a first-line treatment for any fungal infection.
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.

The FDA has removed the drug from its shortage list and set a timeline for pharmacies to stop making compounded versions of the drug — meaning the only version available will be the FDA-approved ...
Earlier this month the US Food and Drug Administration removed a top weight-loss drug from its shortage list, threatening the business of GLP-1 drug compounders and some telehealth providers.
Itraconazole is a relatively well-tolerated drug (although not as well tolerated as fluconazole or voriconazole) and the range of adverse effects it produces is similar to the other azole antifungals: [22] elevated alanine aminotransferase levels are found in 4% of people taking itraconazole
