Description

An antibiotic produced by Streptomyces lincolnensis var. lincolnensis. It has been used in the treatment of staphylococcal, streptococcal, and Bacteroides fragilis infections. [PubChem]

Indication

Lincomycin is an antibiotic used in the treatment of staphylococcal, streptococcal, and Bacteroides fragilis infections.

Pharmacology

Lincomycin is a lincosamide antibiotic that comes from the yeast Streptomyces lincolnensis. Lincomycin has been shown to be active in vitro against the following microorganisms: Aerobic gram-positive cocci: Streptococcus pyogenes and Viridans group streptococci; Aerobic gram-positive bacilli: Corynebacterium diphtheriae; Anaerobic gram-positive non-sporeforming bacilli: Propionibacterium acnes; Anaerobic gram-positive sporeforming bacilli: Clostridium tetani and Clostridium perfringens.

Affected Organisms

Biotransformation

Presumed hepatic, however metabolites have not been fully characterized.

Absorption

Rapidly absorbed from the gastrointestinal tract following oral administration. Approximately 20 to 30% absorbed orally in fasting state; absorption decreased when taken with food.

Half Life

The biological half-life after intramuscular or intravenous administration is 5.4 ± 1.0 hours. The serum half-life of lincomycin may be prolonged in patients with severe impairment of renal function compared to patients with normal renal function. In patients with abnormal hepatic function, serum half-life may be twofold longer than in patients with normal hepatic function.

Protein Binding

Protein binding decreases with increased plasma concentrations. Range, 28 to 86% (average, 70 to 75%). Albumin is not thought to be the primary binding component.

Elimination

Urinary excretion after this dose ranges from 1.8 to 24.8 percent (mean: 3 percent). Tissue level studies indicate that bile is an important route of excretion.
