Potentially Fatal: Serotonin syndrome; transient ischaemic attacks, Stevens-Johnson syndrome.

Drug Interactions

May reduce serum levels w/ rifampicin and phenytoin. May cause hypoglycaemia w/ insulin or oral antidiabetics. May increase risk of seizures w/ tramadol. Potentially Fatal: Increased risk of serotonin syndrome w/ MAOIs, TCAs, SNRIs, or other serotonergic drugs (e.g. bupropion, vilazodone, mirtazapine, amoxapine, buspirone, maprotiline, meperidine, trazodone, nefazodone). Significant increase in BP w/ vasopressive agents (e.g. epinephrine, norepinephrine), sympathomimetic agents (e.g. pseudoephedrine) and dopaminergic agents (e.g. dopamine, dobutamine).

Contraindications

Unless facilities for close observation and BP monitoring, avoid use in patients w/ uncontrolled HTN, pheochromocytoma, thyrotoxicosis, carcinoid syndrome, bipolar depression, schizoaffective disorder, acute confusional states. Patients w/ gm-ve bacterial infections. Concomitant use w/ MAOI or w/in 2 wk of discontinuing MAOI; SSRIs, TCAs, selective serotonin- and norepinephrine-reuptake inhibitors (SNRIs), or other serotonergic drugs (e.g. bupropion, vilazodone, mirtazapine, amoxapine, buspirone, maprotiline, meperidine, trazodone, nefazodone), dopamine, dobutamine, epinephrine, norepinephrine, pseudoephedrine.

Mechanism of Action

Linezolid is a bacteriostatic oxazolidinone which acts by inhibiting ribosomal protein synthesis. It is active against gm+ve bacteria including vancomycin-resistant enterococci and MRSA. It has limited in vitro activity against gm-ve bacteria. Absorption: Rapidly and extensively absorbed after oral admin. Absolute bioavailability: Approx 100%. Time to peak plasma concentration: 1-2 hr but reduced when administered w/ high-fat meal. Distribution: Readily distributed into well-perfused tissues; lungs, fats, bone, skin blister fluids, muscle and into the CSF. Volume of distribution: 40-50 L. Plasma protein binding: Approx 31%. Metabolism: Undergoes hepatic metabolism via oxidation to its 2 inactive metabolites (hydroxyethyl glycine and the aminoethoxyacetic acid metabolite). Excretion: Via urine (approx 30% as parent drug and approx 50% as metabolites); faeces (approx 9% as metabolites). Elimination half-life: Approx 5-7 hr.

Special Precautions

Patients w/ pre-existing myelosuppression, history of seizure, DM, phenylketonuria, mixed (gm+ve and gm-ve) infections. Severe renal impairment. Pregnancy and lactation. Monitoring Parameters Monitor CBC wkly. Monitor visual function in patients on extended therapy (≥3 mth) or in patients w/ new visual symptoms.
