Abstract
Angiotensin II receptor antagonists (ARBs) modulate the function of the renin-angiotensin-aldosterone system and are commonly prescribed antihypertensive drugs, especially in patients with renal failure. In this study, the relationship between several molecular properties of seven ARBs (candesartan, eprosartan, irbesartan, losartan, olmesartan, telmisartan, valsartan) and their fecal elimination data obtained from the literature were investigated. The ARB molecular descriptors were calculated using three software packages. Simple linear regression analysis showed the best correlation between fecal elimination data and lipophilicity descriptor, ClogP values (R-2 = 0.725). Multiple linear regression was applied to examine the correlation of ARBs' fecal elimination data with their lipophilicity and one additional, calculated descriptor. The best correlation (R-2 = 0.909 with an acceptable probability value, P lt 0.05) was established between the ARB fecal elimination data and their lipo...philicity and aqueous solubility data. Applying computed molecular descriptors for evaluating drug elimination is of great importance in drug research.
