Index Cidoxepin

Cidoxepin (former developmental code name P-4599), also known as cis-doxepin or (Z)-doxepin, is a tricyclic antidepressant which was developed in the 1960s but was never marketed. [1]

Allergic rhinitis

Allergic rhinitis, also known as hay fever, is a type of inflammation in the nose which occurs when the immune system overreacts to allergens in the air.

Nordoxepin, also known as N-desmethyldoxepin, is the major active metabolite of the tricyclic antidepressant (TCA) doxepin (Sinequan). It has been found to play a significant role in the antidepressant effects of doxepin. Nordoxepin is a mixture of (''E'') and (''Z'') stereoisomers. Whereas pharmaceutical doxepin is supplied in an approximate 85:15 ratio mixture of (E)- and (Z)-stereoisomers and plasma concentrations of doxepin remain roughly the same as this ratio with treatment, plasma levels of the (E)- and (Z)-stereoisomers of nordoxepin, due to stereoselective metabolism of doxepin by cytochrome P450 enzymes, are approximately 1:1. Nordoxepin is pharmacologically active similarly to doxepin, but relative to doxepin, is much more potent and selective as a norepinephrine reuptake inhibitor. In general, the demethylated variants of tertiary amine TCAs like doxepin are much more potent inhibitors of norepinephrine reuptake, less potent inhibitors of serotonin reuptake, and less potent in their antiadrenergic, antihistamine, and anticholinergic activities. Nordoxepin is formed from doxepin mainly by CYP2C19 (>50% contribution), while CYP1A2 and CYP2C9 are involved to a lesser extent, and CYP2D6 and CYP3A4 are not involved. Hydroxylation of doxepin and nordoxepin is mediated mainly by CYP2D6. Total exposures to both doxepin and nordoxepin differ by almost 10-fold in CYP2D6 ultra-rapid versus poor metabolizers. Both doxepin and nordoxepin are also transformed into glucuronide conjugates. The elimination half-life of nordoxepin is approximately 31 hours, which is almost twice that of doxepin (mean 17 hours).

Receptor antagonist

A receptor antagonist is a type of receptor ligand or drug that blocks or dampens a biological response by binding to and blocking a receptor rather than activating it like an agonist.

Serotonin–norepinephrine reuptake inhibitor

Serotonin–norepinephrine reuptake inhibitors (SNRIs) are a class of antidepressant drugs that treat major depressive disorder (MDD) and can also treat anxiety disorders, obsessive-compulsive disorder (OCD), attention-deficit hyperactivity disorder (ADHD), chronic neuropathic pain, fibromyalgia syndrome (FMS), and menopausal symptoms.
