Description

PEXEVA contains paroxetine mesylate, an SSRI. It is the mesylate salt of a phenylpiperidine compound identified chemically as (-)-trans-4R-(4′-fluorophenyl)-3S-[(3′,4′-methylenedioxyphenoxy) methyl] piperidine mesylate and has the empirical formula of C 19H 20FNO 3•CH 3SO 3H. The molecular weight is 425.5 (329.4 as free base). The structural formula is:

Paroxetine mesylate is an odorless, off-white powder, having a melting point range of 147° to 150°C and a solubility of more than 1 g/ml in water.

PEXEVA tablets are intended for oral administration. Each oval, film-coated tablet contains 10 mg, 20 mg, 30 mg, or 40 mg paroxetine equivalent to 12.9 mg, 25.8 mg, 38.8 mg, or 51.7 mg paroxetine mesylate, respectively. Inactive ingredients consist of dibasic calcium phosphate, hydroxypropyl methylcellulose, hydroxypropylcellulose, magnesium stearate, sodium starch glycolate, titanium dioxide, ferric oxide red (C.I. 77491) (20 mg and 40 mg only) and ferric oxide yellow (C.I. 77492) (20 mg, 30 mg, and 40 mg only).

 Mechanism of Action

The mechanism of action of paroxetine in the treatment of major depressive disorder (MDD), obsessive compulsive disorder (OCD), panic disorder (PD), and general anxiety disorder (GAD) is unknown, but is presumed to be linked to potentiation of serotonergic activity in the central nervous system resulting from inhibition of neuronal reuptake of serotonin (5-HT).
