Brief Summary:
This study will investigate the relative bioavailability of two candidate tablet formulations of 16 milligram (mg) Candesartan cilexetil (GW615775) compared with the reference product ATACAND™ containing 16 mg Candesartan cilexetil in healthy human subjects. This is an open-label, randomized, single dose, three-way crossover, six sequence study enrolling 18 healthy human subjects to ensure at least 14 subjects complete the study as planned. Each subject enrolled will participate in all three treatment periods and will be assigned to one of the six treatment sequences, in accordance with the randomization schedule. The treatment periods will be separated by a washout period of at least 7 days and no more than 14 days between dosing occasions. A follow up visit will be conducted 14-21 days post last dosing. ATACAND is a registered trademark of the AstraZeneca group of companies.

Primary Outcome Measures :
  1. Composite of pharmacokinetic (PK) parameters. [ Time Frame: PK samples will be collected at pre-dose, 0.5, 1, 1.5, 2, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 7.0, 8.0, 10.0, 12.0, 16.0, 24, 36 and 48 hours post dose in each treatment period. ]
    Pharmacokinetic parameters will be measured to estimate the relative bio-availability following administration of two candidate tablet formulations of Candesartan cilexetil relative to reference Candesartan cilexetil tablet. Pharmacokinetic parameters include: maximum observed concentration (Cmax), area under the concentration-time curve from time zero (pre-dose) extrapolated to infinite time (AUC[0-infinite]), Area under the concentration-time curve from time zero (pre-dose) to last time of quantifiable concentration within a subject across all treatments (AUC[0-t]).


Secondary Outcome Measures :
  1. Plasma PK profile [ Time Frame: PK samples will be collected at pre-dose, 0.5, 1, 1.5, 2, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 7.0, 8.0, 10.0, 12.0, 16.0, 24, 36 and 48 hours post dose in each treatment period. ]
    Pharmacokinetic parameters to be estimated include: time of occurrence of Cmax (Tmax), terminal phase half-life (t1/2) and percentage of AUC(0-infinity) obtained by extrapolation (%AUCex).

  2. Vital sign assessment as a safety measure [ Time Frame: Up to 30 days ]
    Vital sign assessment include: blood pressure and pulse rate measurements.

  3. Number of subjects with adverse events as a safety measure [ Time Frame: 50 days ]
    Adverse events will be collected from the start of Study Treatment until the subject's final discharge from study at the end of Treatment Period 3, follow-up call or last outpatient visit, whichever is the latest.

  4. Laboratory parameter assessment as a safety measure [ Time Frame: Up to 30 days ]
    Laboratory parameters include: hematology, clinical chemistry, urinalysis and additional parameters.

Postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous follicle stimulating hormone and estradiol levels consistent with menopause [refer to laboratory reference ranges for confirmatory levels]). Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment.

GSK Modified List of Highly Effective Methods for Avoiding Pregnancy in FRP. This list does not apply to FRP with same sex partners, when this is their preferred and usual lifestyle or for subjects who are and will continue to be abstinent from penilevaginal intercourse on a long term and persistent basis:
