Bioequivalence Study of Amlodipine / Losartan/ Hydrochlorothiazide of PHARMALINE, Lebanon Under Fastion Conditions

Study Overview
=================
Brief Summary
-----------------
To assess the bioequivalence of the investigational TEST product with the marketed REFERENCE products by measurement of Plasma concentrations of Amlodipine ,Losartan, Carboxylic acid losartan metabolite & Hydrochlorothiazide in plasma and calculation of the bioequivalence parameters from those measurements followed by ANOVA and 90% confidence interval statistical evaluation.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: LOSANET AM PLUS (10/100/12.5 mg) of PHARMALINE, Lebanon<br>Subjects will be fasted overnight and receive one tablet by mouth in accordance with randomization table, and blood samples will be taken at specified intervals over 3 days intervention: Drug: LOSANET AM PLUS Amlodipine/ Losartan/Hydrochlorothiazide Other Name: NA | Drug: Amlodipin, losartan, HCTZ<br> <br> * Other names: LOSANET AM PLUS;|
| Active Comparator: NORVASC & HYZAAR (100/12.5 mg)<br>Subjects will be fasted overnight and receive one tablet of Norvasc &HYZAAR by mouth in accordance with randomization table, and blood samples will be taken over 3 days intervention: Drug: LOSANET AM PLUS Amlodipine/ Losartan/Hydrochlorothiazide Other Name: NA | Drug: Amlodipin, losartan, HCTZ<br> <br> * Other names: LOSANET AM PLUS;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To assess the bioequivalence of Test oral formulation of LOSANET AM PLUS versus References NORVASC and HYZAAR. | To assess the bioequivalence of the investigational TEST product with the marketed REFERENCE products by measurement of Plasma concentrations of Amlodipine ,Losartan, Carboxylic acid losartan metabolite & Hydrochlorothiazide in plasma and calculation of the bioequivalence parameters from those measurements followed by ANOVA and 90% confidence interval statistical evaluation. Cmax Ratio: Scaled average bioequivalence will be performed. Bioequivalence limits will be defined and widened according to the variance of σw2 within subject variability for the reference based on Amlodipine, Losartan, & Hydrochlorothiazide AUC Ratio: The 90% confidence interval for this measure lies within an acceptance range of 80.00% - 125.00% based on Losartan, & Hydrochlorothiazide AUC0-72 Ratio: The 90% confidence interval for this measure lies within an acceptance range of 80.00 - 125.00 % based on Amlodipine Carboxylic acid Losartan metabolite will be considered as supportive data | 9 weeks |
