Description

A semi-synthetic antibiotic related to penicillin, Naficillin is a narrow-spectrum beta-lactam antibiotic drug. It is a beta-lactamase-resistant penicillin that is indicated for the treatment of Staphylococcal infections caused by strains that are resistant to other penicillins, except those caused by MRSA. It may be used as a first-line therapy in Methicillin-Sensitive Staphylococcus aureus infections [1].

Pharmacology

Indication

Indicated in the treatment of infections caused by penicillinase-producing staphylococci which have demonstrated susceptibility to the drug.

Structured Indications
Pharmacodynamics

Nafcillin is a semisynthetic antibiotic substance derived from 6-amino-penicillanic acid. The drugs in this class are highly resistant to inactivation by staphylococcal penicillinase and are active against penicillinase-producing and non penicillinase-producing strains of Staphylococcus species.

Mechanism of action

Like other penicillins, nafcillin exerts a bactericidal action against penicillin-susceptible microorganisms during the state of active multiplication in the bacterial cell wall synthesis [FDA Label]. It inhibits the biosynthesis of the bacterial cell wall by forming covalent bonds with penicillin-binding proteins that play a critical role in the final transpeptidation process. Binding to penicillin-binding proteins inhibits the transpeptidase and carboxypeptidase activities conferred by these proteins and prevents the formation of the crosslinks [4].

Absorption

Following intravenous administration of 500mg nafcillin, the mean plasma concentration was approximately 30 µg/mL. This value was reached after 5 minutes of injection [FDA Label].

Volume of distribution

Nafcillin is reported to be widely distributed in various body fluids, including bile, pleural, amniotic and synovial fluids [FDA Label].

Protein binding

The degree of nafcillin binding to serum proteins is 89.9 ± 1.5%, where it is mainly bound to albumin [FDA Label].

Metabolism

Hepatic metabolism accounts for less than 30% of the biotransformation of most penicillins.

Route of elimination

Nafcillin is primarily eliminated by non-renal routes, namely hepatic inactivation and excretion in the bile.

Half life

The serum half-life of nafcillin administered by the intravenous route ranged from 33 to 61 minutes as measured in three separate studies.

Clearance
Not Available
Toxicity

Serious toxicity is unlikely following large doses of nafcillin. Acute ingestion of large doses of nafcillin may cause nausea, vomiting, diarrhea and abdominal pain. Acute oliguric renal failure and hematuria may occur following large doses. The oral LD50 in rats is >5000mg/kg and the intravenous LD50 in rats is >1000mg/kg [MSDS].
