The stratum corneum, the rate-limiting barrier in transdermal drug delivery, is chiral in nature and enantiomers behave differently with respect to their transport across the skin, resulting in enantioselective permeation. The permeation characteristics of individual enantiomers of metoprolol free b
## Abstract Cellulose acetate (CA) is widely used in membrane processes. In this study, CA (weightβaverage molecular weight = 52,000) was mixed with poly(vinyl pyrrolidone) (PVP; weightβaverage molecular weight = 15,000) as an additive in 1βmethylβ2βpyrrolidone as a solvent. The phaseβinversion met
