1. Clinical & Scientific Overview
Tedizolid Phosphate (TIP-MED-000537, Reference Code [R-18]) is classified under
Reserve Antimicrobials (WHO AWaRe Reserve) as a Second-Generation Oxazolidinone Reserve Antibiotic.
Within the Indian regulatory and compendial framework, it is governed under Schedule H1 Reserve Antibiotic.
Sivextro (MSD / Sun Pharma), Tedizolid-200 (Hospital Reserve)
Film-Coated Tablet: 200 mg; Lyophilised Powder for IV Infusion: 200 mg vial
Statutory Restriction, High-Alert & Dispensing Safeguards
Indian Regulatory & Statutory Control Basis: Schedule H1 Reserve Antibiotic
High-Alert Clinical Risk, Dependence & Narrow Therapeutic Index Warnings: Lower incidence of thrombocytopenia and MAO inhibition than linezolid at standard 6-day dosing (200 mg once daily), but optic/peripheral neuropathy risk persists if therapy is extended beyond 6 days.
Mandatory Dispensing Register & Institutional Custody Protocol: 200 mg once daily for 6 days (oral bioavailability >90%, allowing direct 1:1 IV-to-oral switch without dose adjustment).
3. Mechanism of Action & Pharmacodynamics
Prodrug hydrolysed by phosphatases to active tedizolid, which binds the 23S rRNA of the 50S ribosomal subunit to block 70S initiation complex formation; retains activity against some cfr-mediated linezolid-resistant staphylococci.
4. Therapeutic Indications & Evidence-Supported Uses
- Acute bacterial skin and skin structure infections (ABSSSI) caused by MRSA and VRE
🇮🇳 Jurisdiction & Indication Note: Indications and schedules reflect Indian compendial and regulatory records (CDSCO / Indian Pharmacopoeia & NFI / NLEM 2022). Where international reference labels (US FDA DailyMed / NCBI StatPearls) are cited for pharmacokinetic or mechanistic parameters, international approvals do not automatically imply CDSCO approval in India.
5. Educational Dosage Context, Formulations & Administration
Educational Dosing & Regimen Summary: Specialist-Supervised Educational Reference Summary: Dosing of Tedizolid Phosphate must be individualised by a qualified specialist according to clinical indication, organ function, and institutional protocol (Film-Coated Tablet: 200 mg; Lyophilised Powder for IV Infusion: 200 mg vial).
Administration & Meal Timing: Routes: Oral, Intravenous Infusion (over 1 hour). 200 mg once daily for 6 days (oral bioavailability >90%, allowing direct 1:1 IV-to-oral switch without dose adjustment).
6. Pharmacokinetics, Metabolism & Renal/Hepatic Adjustment
Exhibits second-generation oxazolidinone reserve antibiotic pharmacokinetic disposition; verify baseline renal and hepatic clearance and check for active or prolonged-half-life metabolites before repeat dosing.
Hepatic Phase I (CYP450) and/or Phase II conjugation or specific non-renal clearance as detailed in clinical warnings.
Verify eGFR / CrCl before initiation; see specific metabolite and renal clearance notes above.
Assess baseline Child-Pugh status and hepatic transaminases prior to therapy.
7. Contraindications, Precautions & High-Risk Warnings
- Known severe hypersensitivity to Tedizolid Phosphate or formulation excipients
- Unsupervised outpatient self-administration or dispensing without mandatory statutory prescription verification
- Specific clinical contraindications detailed under High-Alert Warnings & Statutory Restrictions
Key Clinical Precautions: Lower incidence of thrombocytopenia and MAO inhibition than linezolid at standard 6-day dosing (200 mg once daily), but optic/peripheral neuropathy risk persists if therapy is extended beyond 6 days.
8. Adverse Effects Profile
- Lower incidence of thrombocytopenia and MAO inhibition than linezolid at standard 6-day dosing (200 mg once daily), but optic/peripheral neuropathy risk persists if therapy is extended beyond 6 days.
- Dose-dependent target-organ pharmacodynamic effects requiring clinical observation
- Lower incidence of thrombocytopenia and MAO inhibition than linezolid at standard 6-day dosing (200 mg once daily), but optic/peripheral neuropathy risk persists if therapy is extended beyond 6 days.
- High-alert toxicity, dependence/diversion risk, or severe organ-specific adverse events if administered outside protocol
9. Major Drug–Drug, Drug–Food & Drug–Herb Interactions
- Lower incidence of thrombocytopenia and MAO inhibition than linezolid at standard 6-day dosing (200 mg once daily), but optic/peripheral neuropathy risk persists if therapy is extended beyond 6 days.
- Review all concomitant CNS depressants, QTc-prolonging agents, nephrotoxins, or CYP450 modulators prior to dispensing.
10. Clinical Monitoring, Patient Counselling & Storage
Clinical & Laboratory Monitoring: 200 mg once daily for 6 days (oral bioavailability >90%, allowing direct 1:1 IV-to-oral switch without dose adjustment).
Pharmacist Patient Counselling Points:
- 200 mg once daily for 6 days (oral bioavailability >90%, allowing direct 1:1 IV-to-oral switch without dose adjustment).
- Must be used strictly under direct medical supervision; never share prescription medicines or alter the prescribed dose.
Storage, Stability & Dispensing Safeguards: 200 mg once daily for 6 days (oral bioavailability >90%, allowing direct 1:1 IV-to-oral switch without dose adjustment).
