Paroxetine is a selective serotonin reuptake inhibitor (SSRI) and paroxetine IR tablets have been approved for the treatment of three anxiety indications in China. This bioequivalence study will evaluate Paroxetine IR tablets manufactured in GSKT (A) and Mississauga (B) sites in healthy Chinese subjects under fasting and fed conditions to support the quality consistency evaluation. This is a single dose, open-label, randomized, two-period crossover study and will include a screening period (up to 7 days), two open-label treatment periods (up to 16 days) and a follow-up phase (up to 14 days after last-dose). The whole study will be divided into two groups, one for fasting condition enrolling approximately 36 subjects and another for fed condition for which approximately 44 subjects will be enrolled. In both groups, eligible subjects will be randomized to receive single dose of Paroxetine IR tablets A or B in a cross-over manner.

Time frame: Baseline (Day-7 to Day -1) and Day 16
Urine samples were collected to assess urine occult blood, urine glucose, urine ketones, urine protein and monitor urine potential of hydrogen (pH). The dipstick test gave results in a semi-quantitative manner, and results for urinalysis parameters (except urine pH) were recorded as negative and positive, indicating proportional concentrations in the urine sample. pH is a measure of hydrogen ion concentration and is used to determine the acidity or alkalinity of urine. Urine pH is calculated on a scale of 0 to 14, values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH of less than 7 is acidic and a pH of greater than 7 is basic. Normal urine has a slightly acidic pH (5.0-6.0). Dipstick test results for pH were presented as number of participants having pH value as 5, 6, 6.5, 7 or 8. Data has been presented treatment-wise.
