Cefaclor and rifampin were measured in the serum and saliva of healthy adult volunteers after ingestion of a liquid formulation and again after capsules of the drugs were given. Antimicrobially active drug was present in most salivary samples after ingestion of suspension of both drugs; however, only rifampin appeared in saliva after ingestion of the capsules. These data correlate with clinical studies of Hemophilus influenzae type b chemoprophylaxis and provide an expla nation of the efficacy of rifampin and the inability of cefacior to eradicate pharyngeal carriage of Hemophilus strains.
