Once daily dosing of oral antimicrobials achieves significantly better patient compliance than three or four times daily dosing, and limited data suggest that this is associated with greater efficacy. Comparison of once daily and twice daily dosing is less consistent, and most studies show only marginally better compliance with once daily dosing versus twice daily dosing. Detection of urinary antimicrobial activity provides a simple method for checking compliance with oral antimicrobials and deserves wider study. Counts of residual tablets have been shown to overestimate compliance. Intravenous formulations are always more expensive than equivalent oral formulations, and preparation and administration of intravenous drugs adds significant additional costs. Moreover, intravenous regimens are complex, and a number of studies have shown that serious errors occur in both preparation and administration of intravenous drugs. There is increasing evidence that serious infections can be adequately treated with oral drugs, and the excellent bioavailability of quinolones makes them particularly attractive for these indications. Clinicians require a method for checking absorption by patients with severe infection, and the Serum Bactericidal Test may provide a practical method for monitoring a wide variety of drugs.
