[Influence of Storage Conditions after One-dose Packaging on Stability of Magnesium Oxide Tablets].

The intestinal motor function declines in the elderly. Many patients have constipation and ingest magnesium oxide for a prolonged period. One-dose packaging of drugs is adopted for many elderly patients to help them to avoid forgetting to take an increase in the number of oral drugs to be taken and improve convenience.

Change in pharmacokinetics of model compounds with different elimination processes in rats during hypothermia.

We compared the pharmacokinetics of model compounds with different elimination processes between hypothermic and normothermic rats, to obtain basic information concerning drug therapy during hypothermia. Male Wistar rats were anesthetized with sodium pentobarbital and kept at temperatures of 37 degrees C (normothermic group) by heat lamp, and 32 degrees C or 28 degrees C (hypothermic group) by external cooling. We chose phenolsulfonphthalein (PSP), indocyanine green (ICG) and fluorescein isothiocyanate (FITC)-dextran (FD-4, Mw 4400) as model compounds to determine changes in clearance pathways during hypothermia therapy.
