Mechanism of Action

Minocycline inhibits protein synthesis by binding to 30S and possibly 50S ribosomal subunits of susceptible bacteria. It is active against Streptococcus aureus, streptococci, Neisseria meningitidis, various enterobacteria, Acinetobacter, Bacteroides, Haemophilus and Nocardia spp, M. leprae and some mycobacteria. Absorption: Absorbed readily from the GI tract (oral); absorption not significantly affected by food and milk. Distribution: Protein-binding: 70-75%. Widely distributed in body tissues and fluids; high concentrations in hepatobiliary tract, lungs, sinuses, tonsils, tears, saliva, sputum. CSF (poor penetration). Crosses the placenta and enters breast milk. Metabolism: Some hepatic metabolism; converted to 9-hydroxyminocycline. Excretion: Via faeces (34%); via urine (5-10%). Elimination half-life: 11-26 hr; prolonged in renal impairment.

Special Precautions

May cause photosensitivity; discontinue at the 1st signs of erythema. May impair ability to drive or operate machinery. Monitor renal, hepatic and haematologic functions during therapy.
