 AB    Concentrations of dapsone, monoacetyldapsone, and pyrimethamine were
       determined in 36 serum samples from human immunodeficiency
       virus-infected patients on prophylaxis with once-weekly administration
       of dapsone-pyrimethamine (200 mg of dapsone-75 mg of pyrimethamine).
       During day 1 after ingestion, median levels of 1,038 ng of dapsone per
       ml and 356 ng of pyrimethamine per ml were found. During days 6 to 7,
       the dapsone level fell to < 20 ng/ml in five of nine serum samples, but
       the pyrimethamine level remained elevated (125 ng/ml). Concurrent, but
       separately ingested, didanosine administration did not seem to decrease
       the drug concentrations.
