Trimethoprim: Prediction of serum concentrations from saliva measurements


Saliva has been used in the past as a non-invasive predictor of serum drug concentration. Prediction may be made from a regression line of saliva versus serum concentration or from an equation proposed by Matin et al. (1974); such predictions have been examined for trimethoprim, a drug that has a pKa of 7.3, the degree of ionisation influencing its… (More)
