Abstract
The cost of intravenously administered histamine2 (H2)-receptor antagonists to hospitalized patients is high. Costs can be expressed as either direct or indirect. Direct costs include drug cost, labor costs (pharmacy/nursing time), and the materials required for iv administration of these agents. Indirect costs include adverse effects, drug interactions, and allergic reactions. Due to the high percentage of total cost for labor and materials associated with the iv H2-receptor antagonists, a reduction in drug cost, although certainly desired, is unlikely to substantially reduce the amount charged the patient per intravenous dose administered or the daily cost of therapy. However, if less frequent dosing were required to achieve similar therapeutic effects, the daily therapy cost for iv H2-receptor antagonists could be substantially reduced. Assuming that cimetidine, ranitidine, and famotidine are equally effective and safe, our cost analyses at the University of Tennessee Medical Center/William F. Bowld Hospital indicate that famotidine administered q12h, regardless of the iv administration technique used, is the most cost-effective H2-receptor antagonist and is the drug of choice.
