Plasma pharmacokinetics of sulfadiazine administered twice daily versus four times daily are similar in human immunodeficiency virus-infected patients

Antimicrob Agents Chemother. 2004 Feb;48(2):635-7. doi: 10.1128/AAC.48.2.635-637.2004.

Abstract

The pharmacokinetics of 2,000 mg of sulfadiazine administered twice daily (BID) versus those of 1,000 mg administered four times a day were compared in eight human immunodeficiency virus-infected patients. No differences in pharmacokinetic parameters were detected between the regimens. These data provide a pharmacokinetic rationale for BID dosing of sulfadiazine for the treatment and suppression of toxoplasmosis.
