Issues pertaining to determination of the pharmacokinetic parameters of calcium preparations are examined using their comparative bioavailability as an example. Pharmacokinetic parameters of calcium such as area under the concentration—time curve (AUC) and maximum concentration (Cmax) are calculated considering the background calcium contents in volunteers. Calcium excretion with urine is assessed as clearance of creatinine, a calcium elimination factor. The dynamics of the content of parathormone (PTH), the main hormone regulating calcium homeostasis, are studied. The results can be used to plan clinical trials for assessing the pharmacokinetics of drug analogs of endogenous compounds.
