Linezolid is a synthetic, antibacterial agent belonging to a new class of antibiotics, the oxazolidinones, with in vitro activity against Gram positive aerobic bacteria, some Gram positive anaerobic bacteria and certain Gram negative bacteria. It selectively inhibits bacterial protein synthesis via a mechanism of action different from that of other antibacterial agents. Linezolid binds to the 23S ribosomal RNA of the 50S subunit of the bacterial ribosome and prevents the formation of a functional 70S initiation complex which is an essential component of the bacterial translation process. The results of time-kill studies have shown Linezolid to be bacteriostatic against enterococci and staphylococci. For streptococci, Linezolid was found to be bactericidal for the majority of strains.

Intravenous administration: Linezolid IV infusion should be inspected visually against a light source for particulate matter prior to administration. Linezolid IV infusion may exhibit a yellow color that can intensify over time without adversely affecting potency. Do not use this intravenous infusion vial in series connections. Additives should not be introduced into this solution. Discard unused portion after single use. Hepatic impairment: No dose adjustment is recommended for patients with mild-to-moderate hepatic impairment. The pharmacokinetics of Linezolid in patients with severe hepatic impairment have not been evaluated. Use in children and adolescents: The dose of linezolid for children and adolescents have been described in dose and administration section. The use of linezolid for the empiric treatment of pediatric patients with central nervous system infections is not recommended * রেজিস্টার্ড চিকিৎসকের পরামর্শ মোতাবেক ঔষধ সেবন করুন'

Drug interaction with medication: Oxalid is a reversible, nonselective inhibitor of monoamine oxidase. Therefore, Oxalid has the potential for interaction with adrenergic and serotonergic agents. Some individuals receiving Oxalid may experience a reversible enhancement of the pressor response to indirect acting sympathomimetic agents, vasopressor or dopaminergic agents. Unless patients are carefully observed for signs and/or symptoms of serotonin syndrome, Oxalid should not be administered to patients with carcinoid syndrome and/or patients taking serotonin re-uptake inhibitors, tricyclic antidepressants, serotonin 5-HT1 receptor agonists (triptans), meperidine or buspirone. Drug interaction with food and others: Advice patients to avoid large quantities of foods or beverages with high tyramine content while taking Oxalid.

Most of the adverse events reported with Oxalid were mild to moderate in intensity. The most common adverse events in patients treated with Oxalid were diarrhea, headache and nausea. Other adverse events includes oral moniliasis, vaginal moniliasis, hypertension, dyspepsia, localized abdominal pain, pruritus, and tongue discoloration.

Pregnancy: Available data with linezolid use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Linezolid should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Lactation: Linezolid is present in breast milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for linezolid and any potential adverse effects on the breastfed child from linezolid or from the underlying maternal condition. Advise lactating women to monitor a breastfed infant for diarrhea and vomiting.

Complete blood counts should be monitored weekly in patients who receive Oxalid, particularly in those who receive Oxalid for longer than two weeks, those with pre-existing myelosuppression, those receiving concomitant drugs that produce bone marrow suppression or those with a chronic infection who have received previous or concomitant antibiotic therapy. If patients experience symptoms of visual impairment, such as changes in visual acuity, changes in color vision, blurred vision or visual field defect, prompt ophthalmic evaluation is recommended. Oxalid is not approved and should not be used for the treatment of patients with catheter-related bloodstream infections or catheter-site infections. Careful medical history is necessary since Clostridium difficile-associated Diarrhea (CDAD) has been reported to occur over two months after antibiotic administration. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Unless patients are monitored for potential increases in blood pressure, Oxalid should not be administered to patients with uncontrolled hypertension, pheochromocytoma, thyrotoxicosis and/or patients taking sympathomimetic agents, vasopressive agents and dopaminergic agents. Patients who develop recurrent nausea or vomiting, unexplained acidosis or low bicarbonate level while receiving Oxalid should receive immediate medical evaluation. If hypoglycemia occurs, a decrease in the dose of insulin or oral hypoglycemic agent or discontinuation of oral hypoglycemic agent, insulin or Oxalid may be required.
