Special Precautions
Patient w/ neuromuscular disorders (e.g. myasthenia gravis), pre-existing vertigo, or hearing loss. Renal impairment. Elderly, childn. Pregnancy and lactation.
Adverse Reactions
Neurotoxic reactions (e.g. vestibular and cochlear function disturbance, optic nerve dysfunction, peripheral neuritis, arachnoiditis, encephalopathy); paraesthesia of face, rash, fever, angioneurotic oedema, eosinophilia; exfoliative dermatitis, azotemia, leucopenia, thrombocytopenia, pancytopenia, haemolytic anaemia, muscular weakness, amblyopia.
Potentially Fatal: Resp paralysis from neuromuscular blockade, Clostridium difficile-associated diarrhoea, anaphylaxis; rarely, nephrotoxicity.
IM/IV/Parenteral: D
MonitoringParameters
Monitor renal and auditory function.
Drug Interactions
Additive neurotoxic and nephrotoxic effect w/ neomycin, kanamycin, gentamicin, cefaloridine, paronomycin, viomycin, polymyxin B, colistin, tobramycin, and ciclosporin. Enhanced ototoxic and nephrotoxic effect w/ ethacrynic acid, mannitol, furosemide and possibly other diuretics. May enhance the resp depressant effect of neuromuscular blockers. Increased risk of nephrotoxicity w/ cephalosporins. Reduced excretion w/ NSAIDs.
Action
Description: Streptomycin inhibits bacterial protein synthesis by binding directly to the 30S ribosomal subunits causing faulty peptide sequence to form in the protein chain.
Pharmacokinetics:
Absorption: Not absorbed from the GI tract. Rapidly absorbed (IM). Time to peak plasma concentration: 0.5-2 hr.
Distribution: Rapidly distributed into most body tissues and fluids except the brain. Crosses the placenta and enters breast milk. Plasma protein binding: Approx 1/3 of the drug in circulation.
Excretion: Via urine, approx 30-90% as unchanged drug. Half-life: Approx 2.5 hr.
