A new generation drug delivery system, named the Microsealed Drug Delivery (MDD) system, was developed. Subcutaneous implantation of MDD's in rats for up to 129 days resulted in a constant release profile of desoxycorticosterone acetate. Three formulations were examined. An excellent i n uitro-in ui

β¦ Synopsis
The antimicrobial effects of some analgesics, antipyretics, antimalarials, and tranquilizers were determined. The phenothiazines were the most active group. The effect of the chosen drugs when combined with a selected number of antibiotics was studied on Staphylococcus aureus and Escherichia coli to determine the type of interaction. Most analgesics, antipyretics, and antimalarials showed either no effect or a synergistic action. However, some exhibited antagonistic effects. All tested tranquilizers were synergistic. Preliminary studies, using electronic absorption spectrometry, indicated that the antagonistic action may be attributed to a physical interaction.
