Phenindamine

1H-Indeno(2,1-c)pyridine, 2,3,4,9-tetrahydro-2-methyl-9-phenyl-, hydrochloride

C19H19N (261.1517)

Phenindamine is an antihistamine. Phenindamine blocks the effects of the naturally occurring chemical histamine in your body. Antihistamines such as phenindamine appear to compete with histamine for histamine H1- receptor sites on effector cells. The antihistamines antagonize those pharmacological effects of histamine which are mediated through activation of H1- receptor sites and thereby reduce the intensity of allergic reactions and tissue injury response involving histamine release. It is used to treat sneezing, runny nose, itching, watery eyes, hives, rashes, itching, and other symptoms of allergies and the common cold. Symptoms of a phenindamine overdose include extreme sleepiness, confusion, weakness, ringing in the ears, blurred vision, large pupils, dry mouth, flushing, fever, shaking, insomnia, hallucinations, and possibly seizures.

desmethylcyclobenzaprine

methyl(3-{tricyclo[9.4.0.0³,⁸]pentadeca-1(15),3,5,7,9,11,13-heptaen-2-ylidene}propyl)amine

C19H19N (261.1517)

desmethylcyclobenzaprine is a metabolite of cyclobenzaprine. Cyclobenzaprine, brand name Flexeril, is a muscle relaxant medication used to relieve skeletal muscle spasms and associated pain in acute musculoskeletal conditions. It is the most well-studied drug for this application, and it also has been used off-label for fibromyalgia treatment. A new bedtime formulation of cyclobenzaprine is under development for the management of fibromyalgia syndrome. (Wikipedia)

Setiptiline

4-methyl-4-azatetracyclo[13.4.0.0²,⁷.0⁸,¹³]nonadeca-1(19),2(7),8,10,12,15,17-heptaene

C19H19N (261.1517)

C78272 - Agent Affecting Nervous System > C265 - Antidepressant Agent > C94727 - Tricyclic Antidepressant Setiptiline (Org-8282) is a serotonin receptor antagonist. Setiptiline is a tetracyclic antidepressant (TeCA) which acts as a noradrenergic and specific serotonergic antidepressant (NaSSA). Setiptiline acts as a norepinephrine reuptake inhibitor, α2-adrenergic receptor antagonist, and serotonin receptor antagonist, likely at the 5-HT2A, 5-HT2C, and/or 5-HT3 subtypes, as well as an H1 receptor inverse agonist/antihistamine.
