Description
Sources: https://www.drugs.com/pro/nafcillin.html

Nafcillin is a beta-lactam antibiotic of penicillin class. As a beta-lactamase-resistant penicillin, it is used to treat infections caused by Gram-positive bacteria, in particular, species of staphylococci that are resistant to other penicillins.

Stafillococcal infection 4 Sources: https://www.drugs.com/pro/nafcillin.html	Curative		Approved 8360	UNIPEN Approved Use Nafcillin for injection, USP is indicated in the treatment of infections caused by penicillinase-producing staphylococci which have demonstrated susceptibility to the drug. Culture and susceptibility tests should be performed initially to determine the causative organism and its susceptibility to the drug. Nafcillin for injection, USP may be used to initiate therapy in suspected cases of resistant staphylococcal infections prior to the availability of susceptibility test results. Nafcillin for injection, USP should not be used in infections caused by organisms susceptible to penicillin G. If the susceptibility tests indicate that the infection is due to an organism other than a resistant Staphylococcus, therapy should not be continued with nafcillin for injection, USP. To reduce the development of drug-resistant bacteria and maintain the effectiveness of nafcillin for injection, USP and other antibacterial drugs, nafcillin for injection, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Launch Date 8.2944E9

Sample Use Guides

In Vivo Use Guide

Nafcillin for Injection ADD-Vantage® Vial is to be administered intravenously. The usual I.V. dosage for adults is 500 mg every 4 hours. For severe infections, 1 gram every 4 hours is recommended. Administer slowly over at least 30 to 60 minutes to minimize the risk of vein irritation and extravasation. Bacteriologic studies to determine the causative organisms and their susceptibility to Nafcillin should always be performed. Duration of therapy varies with the type and severity of infection as well as the overall condition of the patient; therefore, it should be determined by the clinical and bacteriological response of the patient. In severe staphylococcal infections, therapy with Nafcillin should be continued for at least 14 days. Therapy should be continued for at least 48 hours after the patient has become afebrile, asymptomatic, and cultures are negative. The treatment of endocarditis and osteomyelitis may require a longer duration of therapy.

In Vitro Use Guide

MICs and minimum bactericidal concentrations (MBCs) were determined for in triplicate by microdilution techniques using an inoculum of 5 × 105 CFU/ml according to Clinical and Laboratory Standards Institute guidelines. For MBC determinations, aliquots (5 μl) from clear wells were plated onto tryptic soy agar drug-free plates followed by incubation at 37°C for 24 and 48 h. MIC data were reported as median values from at least three independent experiments for each antibiotic. MIC for nafcillin-sensitive S.aureli strains was determined to be 1 ug/ml.
