Arm && Interventions

Group	Intervention	Description
Tylenol® Caplets, then Mejoral® 500 Tablets	Tylenol® Caplets	Participants will first receive one tablet \[500 milligram (mg) of paracetamol\] of Tylenol® Caplets, orally with 250 mL of water at room temperature, in a single dose, under minimum 10 h fasting. After a washout period of 72 h, they then will receive one tablet (500 mg of paracetamol) of Mejoral® 500 tablets, orally with 250 mL of water at room temperature, in a single dose, under minimum 10 h fasting.

Primary Outcome Measures

Name	Time	Method
Area Under the Curve From Time Zero Extrapolated to Infinity [AUC(0-inf)]	2 days	AUC(0-inf) of paracetamol was calculated using the trapezoidal rule. Blood samples were taken before the administration of the reference/test product (pre-dose) and at 0.250, 0.333, 0.500, 0.667, 0.833, 1.000, 1.250, 1.500, 1.750, 2.000, 4.000, 6.000, 8.000, 12.000 and 16.000 h after each period.
Maximum Plasma Concentration (Cmax)	2 days	Cmax of paracetamol was obtained graphically from the plasma concentration over time profile. Blood samples were taken before the administration of the reference/test product (pre-dose) and at 0.250, 0.333, 0.500, 0.667, 0.833, 1.000, 1.250, 1.500, 1.750, 2.000, 4.000, 6.000, 8.000, 12.000 and 16.000 h after each period.
Area Under the Curve From Time Zero to Last Sampling Time [AUC(0-t)]	2 days	AUC(0-t) of paracetamol was calculated using the trapezoidal rule. Blood samples were taken before the administration of the reference/test product (pre-dose) and at 0.250, 0.333, 0.500, 0.667, 0.833, 1.000, 1.250, 1.500, 1.750, 2.000, 4.000, 6.000, 8.000, 12.000 and 16.000 hours (h) after each period.

Secondary Outcome Measures

Time to Reach Maximum Plasma Concentration (Tmax)	2 days	Tmax of paracetamol was obtained graphically from the plasma concentration over time profile. Blood samples were taken before the administration of the reference/test product (pre-dose) and at 0.250, 0.333, 0.500, 0.667, 0.833, 1.000, 1.250, 1.500, 1.750, 2.000, 4.000, 6.000, 8.000, 12.000 and 16.000 h after each period.
