Bioequivalence of Two Azilsartan Formulations
Conditions
Brief summary
The purpose of this study was to determine the bioequivalence of two azilsartan formulations after administration of single doses to healthy subjects under fasted and fed conditions. These data were to be evaluated statistically to determine if the products meet bioequivalence criteria.

Non-lactating women and willing to use appropriate contraceptive methods such as an intrauterine device (IUD), diaphragm with spermicides or abstinence or have a sterile sexual partner (e.g., vasectomy) during the whole study period. Men willing to use an appropriate method of contraception (such as condom with spermicide or use by partner of oral, implantable or injectable contraceptives, IUD, diaphragm, with spermicides) or abstinence or will have a sterile sexual partner during the whole study period; 5. Subjects understand the nature, significance, possible benefits, inconveniences and potential risks before participating in this trial, understood the trial process, and are voluntary to sign the informed consent form and to participate in this trial.
Exclusion criteria
1. Subjects who have abnormalities with clinical significance in physical examination, laboratory examinations, 12-lead ECGs, chest X-ray; 2. Subjects with clinically significant history of orthostatic hypotension, chronic gastrointestinal disease (such as gastric ulcer, gastritis, etc.), renal disease (such as nephritis, pyelonephritis, etc.), or cardiovascular, respiratory, neurological, psychotic, haematological, endocrine or other disorders within the past 6 months before randomization or at the discretion of the investigators; 3. Subjects with allergic history to Angiotensin Receptor Blockers or other anti-hypertensive drugs or anti-hypertensive biological agents; 4. Sitting systolic blood pressure (SBP) \<80mmHg or \>140mmHg, and/or sitting diastolic blood pressure (DBP) \<50mmHg or \>90mmHg at screening; 5. With the history of using any drug which will inhibit (chlorpromazine, cimetidine, ciprofloxacin, metronidazole, chloramphenicol, isoniazid and sulphonamide) or induce liver metabolize drug (barbiturate, carbamazepine, aminoglutethimide, grifulvin, ethanol, ammonia methyl propyl, phenytoin, rifampin, glutethimide, dexamethasone, sulfinpyrazone) within 1 month before randomization; 6. Vegetarian or abnormal diets (\<1600 or \>3500 kcal/day) or substantial changes in eating habits within the past 4 weeks prior to screening; 7. History of alcohol abuse in the last 6 months prior to screening defined as an average weekly intake of greater than 14 unit (one unit is equivalent to 360ml of beer or 45ml of spirits with 40% alcohol content or 150 ml of wine); or subjects with positive alcohol breath test; 8. History of smoking \>5 cigarettes a day in the last 6 months prior to screening; 9. History of drug abuse and taking drugs (such as marijuana, cocaine, opiates, benzodiazepines, amphetamines, barbiturates, tricyclic antidepressant) or subjects with positive urine drug abuse test results; 10. Consumption of excessive amount of tea, coffee and/or caffeinated beverage (more than 8 cups/day, 200mL/cup) in the last 1 month prior to screening; 11. Subjects who have participated in clinical trial (as subjects) in the last 3 months prior to screening; 12. Blood donation of 250 ml or more in the 3 months prior to screening; 13. Positive result of hepatitis B antigen, hepatitis C antibody, HIV antibody or syphilis antibody; 14. Consumption of grapefruit juice, xanthine diet, chocolate, coffee or tea, carbonated beverages, or any other caffeinated beverages within 48 hours before randomization; 15.
