Abstract: The modulation of host antimicrobial activity by antibiotics is of therapeutic importance. The effect of serum on drug activity is also of clinical interest. We studied the effect of roxithromycin on the opsonizing time of plasma and the oxygen consuming activity of phagocytes in peripheral whole blood that reflects in vivo bacteremia more than isolated serum and granulocytes. Roxithromycin has no effect on the opsonizing activity at any concentrations we examined. At lower concentration (<50μg/ml), roxithromycin does not give any effects on zymosan-stimulated oxygen consumption either. At the highest concentration (200μg/ml) we examined, the antibiotic however decreases it to the extent comparable to that reported in serum-free reconstituted in vitro system. These results indicate that roxithromycin has modulatory effects neither on anti-microbial oxygen metabolism of phagocytes nor on the opsonizing activity of plasma at pharmacological concentration, but is inhibitory on the former at its toxic concentration. On the other hand, serum proteins have no effects on drug toxicity in this context in comparison to in vitro studies (24, 30).
