Description
FDA has not yet classified the drug into a specified pregnancy category.
Mode of Action
Ciprofloxacin promotes breakage of double-stranded DNA in susceptible organisms and inhibits DNA gyrase, which is essential in reproduction of bacterial DNA.
Interaction
May increase plasma concentrations of CYP1A2 substrates (e.g. clozapine, ropinirole, theophylline). Enhances effect of oral anticoagulants (e.g. warfarin) and glibenclamide. Increased toxicity of methotrexate. Plasma concentrations may be increased by probenecid. Reduced absorption w/ oral multivitamins and mineral supplements containing divalent or trivalent cations (e.g. Fe, Zn, Ca) and antacids containing Al, Ca or Mg. Concomitant use w/ class IA antiarrhythmics (e.g. quinidine, procainamide), class III antiarrhythmics (e.g. amiodarone, sotalol), TCAs, macrolides and antipsychotics may result in additive effects on QT interval prolongation. Concurrent use w/ corticosteroids may increase risk of severe tendon disorders. Increased risk of CNS stimulation w/ NSAIDs. Altered serum concentrations of phenytoin.
Potentially Fatal: Marked elevation in serum levels of tizanidine which is associated w/ potentiated hypotensive and sedative effect.
Pregnancy Category Note
Pregnancy
Data are not available regarding use in pregnant women; owing to negligible systemic exposure associated with otic administration of ciprofloxacin, minimal risk is expected
Lactation
Ciprofloxacin is excreted in human milk with systemic administration; however, owing to negligible systemic exposure after otic administration, breastfed infants should not be affected
