Ethanol-moxalactam interactions in vivo.

Area of Science:

• Pharmacology
• Biochemistry

Background:

• Disulfiram-like reactions have been observed with moxalactam.
• Ethanol metabolism involves acetaldehyde accumulation.

Purpose of the Study:

• To investigate if moxalactam causes acetaldehyde accumulation during ethanol metabolism.
• To compare moxalactam's effect to disulfiram.

Main Methods:

• Male Wistar rats were administered moxalactam and ethanol.
• Blood ethanol and acetaldehyde concentrations were measured using gas chromatography.

Main Results:

• Moxalactam increased acetaldehyde concentrations, similar to disulfiram but to a lesser extent.
• Cefamandole and cefoperazone also increased acetaldehyde levels.
• Penicillin G and other cephalosporins did not affect acetaldehyde levels.

Conclusions:

• Moxalactam, cefamandole, and cefoperazone can cause disulfiram-like reactions due to acetaldehyde accumulation.
• Patients treated with these antibiotics should avoid alcohol for several days.
