“…enantiomers (see Fig. 1) (Witiak et al 1981;Craig et al 1988;Titus 1989;Brocks et al 1992;Brocks and Mehvar 2003) with variable stereo-selective elimination (Iredale et al 1993;McLachlan et al 1993McLachlan et al , 1994Tett et al 1994;Ducharme et al 1995;Midha et al 1998;Munster et al 2002;Brocks and Mehvar 2003;de Oliveira et al 2007); (c) wide variability in the concentration profiles from sampling of blood or plasma which is possibly due to differences in the sensitivity of analytical methods and calculations of kinetic parameters, especially the terminal elimination plasma half-life (T 1/2 ) Titus 1989); (d) marked variations of plasma concentrations in relation to dosage as well as Fig. 1 The stereochemistry is important for determining the pharmacokinetics of the drug which exists as a racemic mixture of R-(-) and S(?)…”

“…Specifically, (S)-ketoprofen is a main compound for these effects, while the (R)-ketoprofen has unnecessary side effects [3]. Therefore, several methods to prepare (S)-ketoprofen are investigated including asymmetric synthesis, enzymatic, and chemical resolution with different effectiveness [4,5].…”

“…Estudos têm mostrado que β-bloqueadores, propranolol é um exemplo, se ligam estereosseletivamente a receptores β-adrenérgicos e que os enantiômeros (-)-são os principais responsáveis pela atividade β-bloqueadora dessa classe de fármacos 7 . Adicionalmente, quando um fármaco quiral é administrado como racemato, os dois enantiômeros podem apresentar os processos de absorção, distribuição, metabolização e excreção (disposição cinética) de forma estereosseletiva [8][9][10][11] . Desses processos, a estereosseletividade é mais significativa no metabolismo, devido ao envolvimento do sistema enzimático.…”
