Study Description

Brief Summary:

The current study is conducted to evaluate and compare the relative bioavailability for Quetiapine in two different products containing 25 mg Quetiapine after a single oral dose administration under fasting conditions.

Condition or disease	Intervention/treatment	Phase
Bioequivalence	Drug: Test product (T) 25 mg Film Coated Tablets; Drug: Reference product (R) 25 mg Film Coated Tablets	Phase 1

Detailed Description:

A randomized, single-dose, partial replicate, three-phase, three-sequence, bioequivalence study of the two study products. Blood samples were collected at different time intervals and stored at -70⁰C freezer. Quetiapine plasma concentrations were analyzed using a validated LC-MS-MS method then pharmacokinetics and statistical analysis were performed on the concentrations obtained using Phoenix WinNonlin® software.

Arms and Interventions

Arm	Intervention/treatment

Outcome Measures

Primary Outcome Measures :

1. Maximum plasma concentration (Cmax) [ Time Frame: Pre-dose (0), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12 and 24 hours post dose ]
   Cmax is observed as the maximum of Quetiapine peak concentration
2. Area under the plasma concentration curve from administration to last observed concentration at time t (AUC(0-t)) [ Time Frame: Pre-dose (0), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12 and 24 hours post dose ]
   The AUC (0-t) is the area under the plasma concentration versus time curve from time zero (predose) to time of last quantifiable concentration (tlast)
3. Area under the plasma concentration curve extrapolated to infinite time (AUC(0-inf)) [ Time Frame: Pre-dose (0), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12 and 24 hours post dose ]
   AUC(0-inf) "the area under the curve," which is a way of measuring the total amount of the active drug in a subject's system over a period of time from administration ("0") to the time that the drug is no longer present in the subject's body ("infinity")

Secondary Outcome Measures :

1. Maximum time (Tmax) [ Time Frame: Pre-dose (0), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12 and 24 hours post dose ]
   Time until Cmax is reached
2. Elimination Rate Constant (Kel) [ Time Frame: Pre-dose (0), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12 and 24 hours post dose ]
   Kel is a value used in pharmacokinetics to describe the rate at which a drug is removed from the human system
3. Plasma concentration half-life (t1/2) [ Time Frame: Pre-dose (0), 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12 and 24 hours post dose ]
   t1/2 is the time taken for the plasma concentration of a drug to reduce to half its original value. It is used to estimate how long it takes for a drug to be removed from your body.
