Application

Paroxetine hydrochloride hemihydrate has been used: as an antidepressant to study its effects on neural stem cells (NSCs) from embryonic rat hippocampus in vitro; as a CYP 2D6 inhibitor to study its effects on the in vitro production by human recombinant CYP 2D6 of the phenolic metabolites; as an antidepressant to study its effects on the expression of pituitary adenylate cyclase activating polypeptide (PACAP), its receptors and brain-derived neurotrophic factor (BDNF) in rat primary hippocampal neurons

Biochem/physiol Actions

Paroxetine hydrochloride hemihydrate is one of the most potent and selective of the selective serotonin reuptake inhibitors (SSRI); antidepressant
Paroxetine is a phenylpiperidine derivative. It has the ability to cross placenta. Paroxetine is known to increase the risk of congenital cardiac malformations. It might be useful in hormone replacement therapy for treating vasomotor symptoms during menopause. It is known to ameliorate the effects of panic disorder, obsessive‐compulsive disorder and social phobia.

Antidepressants target the serotonin transporter (SERT) by inhibiting serotonin reuptake. Structural and biochemical studies aiming to understand binding of small-molecules to conformationally dynamic transporters like SERT often require thermostabilizing mutations and antibodies to stabilize a specific conformation, leading to questions
