bioequivalence study of anplag® 90mg (ticagrelor) tablet & brilinta® 90 mg (ticagrelor) tablet in healthy adult male pakistani subjects under fasting condition

Conditions: Healthy Individuals

Summary: single oral administration of study drugs (i.e. anplag® \& brilinta®) in two periods after at least 10 hours fasting. the periods will be separated by a washout period of 7 days. the purpose of this study is to compare the bioavailability of anplag® 90mg (ticagrelor) tablet with brilinta® 90 mg (ticagrelor) tablet under fasting conditions in healthy pakistani male subjects.

the subjects will be randomly assigned in period 1 to t or r sequence and will be administered the study drugs t (anplag® 90 mg) or r (brilinta® 90 mg) with 240 ml ambient temperature water following at least 10 hours fasting. blood samples will be withdrawn at pre-determined time points for estimation of plasma drug concentration upto 48 hours post dose. the subjects will be crossed over in period 2 separated by a washout period of 7 days and administered rt sequence in period 2. similar procedure of blood sampling will be applied for estimation of plasma drug concentration upto 48 hours post dose.

a personal history of severe hemorrhage, non-traumatic bleeding, bleeding risks, hematemesis, melena, hemoptysis, severe epistaxis, severe thrombocytopenia, intracranial hemorrhage; or rectal bleeding within 1 year prior to screening; or history suggestive of peptic ulcer disease; or at the discretion of the investigator. * platelet count is less than 150 x 10\^9/l. * subject has had a blood test that showed more than the usual amount of uric acid. * subjects receiving oral anticoagulants often referred to as "blood thinners" which include warfarin. * history of any significant illness in the last four weeks . * consumption of grapefruit and/or its products within 14 days prior to the start of study. * subjects who test positive for syphilis (vdrl) or who are known to have serum hepatitis or who are carriers of the hepatitis b surface antigen (hbs ag) or are carriers of antibodies to hepatitis c virus (anti-hcv), human immunodeficiency virus (hiv-1 or hiv-2) or covid-19. * individuals having undergone any major surgery (including dental work) within 3 months prior to the start of the study, unless deemed eligible, otherwise by the principal investigator or whomever he/she may designate. * subject has a history of any illness that, in the opinion of investigator might confound the result of the study or pose any risk in administrating ticagrelor to the subject. * subjects with any condition, which, in the opinion of the investigator, may interfere with the absorption, distribution, metabolism or elimination of drugs.
