Is ketamine distribution described by a recirculatory pharmacokinetic model stereoselective?
Although the elimination clearance of S-(+)-ketamine is 35% greater than that of the R-(-)-enantiomer, there is no difference in the apparent pulmonary tissue volume or peripheral tissue distribution between the stereoisomers, suggesting that physicochemical properties of ketamine other than stereoisomerism determine its perfusion-limited tissue distribution.
Patching a corneal erosion does not significantly accelerate reepithelialization and does not alter the epithelial wound healing pattern. It does not reduce the incidence and severity of inflammation nor relieve pain when compared with treatment without patching.
