In summary, more than 55% of the drug products were classified as high-solubility (Class 1 and Class 3) drugs in the four lists, suggesting that in vivo bioequivalence (BE) may be assured with a less expensive and more easily implemented in vitro dissolution test. , metoprolol vs cimetidine or atenolol, show excellent agreement in drug classification.
Toni Braxton And Babyface Love Marriage And Divorce Full Album Download. Although the two approaches are based on different in vivo processes, fraction dose metabolized and fraction dose absorbed are highly correlated and, while depending on the choice of reference drug for permeability classification, e.g.
We have compared the BCS classification in this study with the recently proposed BDDCS classification based on fraction dose metabolism. Metoprolol was chosen as the reference compound for permeability and Log P or CLogP.Ī total of 62−69.0% and 56−60% of the drugs on the four lists exhibited CLogP and Log P estimates, respectively, greater than or equal to the corresponding metoprolol value and are provisionally classified as high-permeability drugs. The Log P and CLogP estimates were linearly correlated ( r 2 = 0.79) for 187 drugs. The provisional classification of permeability is based on correlations of the human intestinal permeabilities of 29 reference drugs with the calculated Log P or CLogP lipophilicity values for the uncharged chemical form. More than 50% of the oral IR drug products on each list were determined to be high-solubility drugs (55−59%). Oral IR drug products constituted more that 50% of the top 200 drug products on all four lists, and ranged from 102 to 113 in number.ĭrugs with dose numbers less than or equal to unity are defined as high-solubility drugs. The provisional classification is based on the aqueous solubility of the drugs reported in readily available reference literature and a correlation of human intestinal membrane permeability for a set of 29 reference drugs with their calculated partition coefficients. Orally administered, immediate-release (IR) drug products in the top 200 drug product lists from the United States (US), Great Britain (GB), Spain (ES), and Japan (JP) were provisionally classified based on the Biopharmaceutics Classification System (BCS). The Biopharmaceutics Classification System (BCS) is a scientific framework for classifying drug substances based on their aqueous solubility and intestinal permeability. The potential applications of BCS in drug discovery, drug delivery and drug research as. The Biopharmaceutics Classification System (BCS) is a scientific.
