Effect of antibiotics and sedatives on normal neutrophil nicotinamide-adenine dinucleotide phosphate-reduced oxidase activity. 1986

B C Moon, and M J Girotti, and S F Wren, and R Dawson, and D Brar

The effects of antibiotics and other commonly used medications on the human polymorphonuclear neutrophil leukocytes' (PMNs) nicotinamide-adenine dinucleotide phosphate-reduced (NADPH) oxidase activity have been investigated in vitro. Five antibiotics (penicillin G sodium, cefamandole nafate, metronidazole hydrochloride, clindamycin phosphate, and tobramycin sulfate, and a triple combination of penicillin G sodium-metronidazole hydrochloride-tobramycin sulfate) and two sedatives (morphine sulfate and diazepam) were incubated with normal human PMNs at therapeutic, infratherapeutic, and supratherapeutic drug levels. The superoxide dismutase-inhibitable, NADPH-dependent reduction of cytochrome C in the PMNs was studied after stimulation with formyl-methionyl-leucine-phenylalanine. Tobramycin sulfate and the triple combination of penicillin G sodium-metronidazole hydrochloride-tobramycin sulfate significantly reduced the NADPH oxidase activity at all dosages studied. Clindamycin phosphate, morphine sulfate, and diazepam also showed significant reduction at therapeutic and supratherapeutic concentrations. Penicillin G sodium, cefamandole nafate, and metronidazole hydrochloride did not cause a decrease in enzyme activity at any levels tested. We conclude that NADPH oxidase activity can be adversely affected by the circulating levels of common antibiotics and sedatives.

D009247	NADH, NADPH Oxidoreductases	A group of oxidoreductases that act on NADH or NADPH. In general, enzymes using NADH or NADPH to reduce a substrate are classified according to the reverse reaction, in which NAD+ or NADP+ is formally regarded as an acceptor. This subclass includes only those enzymes in which some other redox carrier is the acceptor. (Enzyme Nomenclature, 1992, p100) EC 1.6.
