Paroxetine HCl (BRL-29060A, FG-7051) is an antidepressant drug of the SSRI type.
Paroxetine apparently exerts their antidepressant activity by increasing the concentration of 5-HT in the extracellular compartment, thereby enhancing serotoninergic neurotransmission. Paroxetine (1-300 μM) results in a concentration-dependent reduction in the firing rate of DRN serotoninergic neurons with IC50 values of 1.4 μM in the ACSF superfusing brain stem slices. [1] Paroxetine is a highly potent inhibitor of desipramine hydroxylation, the inhibition constant (Ki) value of 2.0 mM indicated greater inhibiting potency than fluoxetine or norfluoxetine. [2] Paroxetine is shown to be a potent (Ki = 1.1 nM) and specific inhibitor of [3H]-5-hydroxytryptamine (5-HT) uptake into rat cortical and hypothalamic synaptosomes in vitro. Paroxetine demonstrates weak affinity for muscarinic receptors (Ki = 89 nM) but is at least 15 fold weaker than amitriptyline (Ki = 5.1 nM). [3] Paroxetine inactivates CYP2D6 via the formation of a metabolite intermediate complex. [4]
Paroxetine produces a dose-related inhibition of [3H]-5-HT uptake (ED50 = 1.9 mg/kg) into rat hypothalamic synaptosomes ex vivo with little effect on [3H]-l-noradrenaline (NA) uptake (ED50 greater than 30 mg/kg). Paroxetine (ED50 1-3 mg/kg PO) prevents the 5-HT depleting effect of p-chloroamphetamine (PCA) in rat brain, demonstrating 5-HT uptake blockade in vivo. [3]

Cell experiment: | Cell viability is determined by the tetrazolium salt 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. BV2 and primary microglial cells are initially seeded into 96-well plates at a density of 1×104 cells/well and 5×104 cells/well, respectively. Following treatment, MTT (5 mg/mL in PBS) is added to each well and incubated at 37°C for four hours. The resulting formazan crystals are dissolved in dimethylsulfoxide (DMSO). The optical density is measured at 570 nm, and results are expressed as a percentage of surviving cells compared with the control. |
Animal experiment: | Animals are divided into two main groups: 1) pre-emptive and 2) post-injury group. Each main group is divided into three different subgroups: I) CCI vehicle-treated group, II) sham group, and III) CCI paroxetine-treated group. Vehicle is injected i.p. to CCI and sham-operated animals. In the pre-emptive study, paroxetine (10 mg/kg) is injected 1 h before surgery and continued daily until day 14 post surgery. In the post-injury group, paroxetine (10 mg/kg) is administered at day 7 post injury and continued daily until day 14. All behavioral tests are recorded on day 0 (control day) before surgery and on days 1, 3, 5, 7, 10, and 14 post-nerve injury. |
