The Shift Toward All-Oral MDR-TB Regimens
The treatment landscape for multidrug-resistant (MDR) and rifampicin-resistant (RR) tuberculosis is undergoing a significant transformation. For years, patients faced grueling treatment paths characterized by long durations and high toxicity. However, we are seeing a decisive move toward newer, all-oral regimens that prioritize patient-centered care.
One of the most promising advancements is the BPaLM regimen, which combines bedaquiline, pretomanid, linezolid, and moxifloxacin. Unlike traditional treatments, these all-oral options eliminate the need for injectable aminoglycosides, which were historically linked to high toxicity.
Overcoming Implementation Hurdles: The UK Model
Transitioning to new clinical guidelines is rarely seamless. In the UK, the adoption of shorter regimens faced hurdles including fragile supply chains, the high cost of second-line antituberculosis drugs, and pharmacokinetic concerns.
To navigate these challenges, a coordinated effort emerged between the National Health Service England (NHSE), the British Thoracic Society (BTS) MDR-TB Clinical Advice Service, and various specialist clinical networks. This collaboration ensures that antimicrobial stewardship (AMS) principles are maintained while expanding patient access.
Managing High Costs and Supply Chains
Securing expensive medications requires strategic policy reform. The NHSE supported the commissioning of high-cost drugs to ensure equitable access for eligible patients. Stakeholders—including clinicians, pharmacists, and the NHSE—worked together to secure volume commitments, effectively preventing supply disruptions that could otherwise delay critical treatment.
The Pathway to Treatment
The UK has established a streamlined pathway to ensure patients receive the right care quickly:
- Diagnosis: Patients are referred to an MDR-TB center to discuss potential treatment options.
- Clinical Advice Services: Through a specialized account, patients can receive regimen approval following online discussions with two clinical advisors.
- Prescribing and Monitoring: The final stage involves the administration of drugs and ongoing monitoring for drug interactions and adverse effects.
Why Shorter Treatment Durations Matter
The move toward treatment durations of 6–9 months is a game-changer for patient outcomes. Shorter courses are expected to result in fewer adverse reactions and significantly lower toxicity compared to older, longer regimens.
Beyond the physical health benefits, the reduction in treatment length directly impacts adherence. When patients face a less daunting timeline and fewer severe side effects, the likelihood of treatment completion increases, which is vital for curing the disease and preventing further resistance.

The Broader Impact on Antimicrobial Resistance
The adoption of these regimens is not just a win for individual patients; it is a strategic move in the fight against global antimicrobial resistance (AMR). By utilizing more effective, shorter-term treatments, the healthcare system supports the goals of the UK AMR Action Plan.
The success of this approach is already evident. Up to January 2026, 54 out of 60 requests for pretomanid-containing regimens were approved in the UK, signaling a robust framework for managing evolving treatment landscapes.
Frequently Asked Questions
What is the BPaLM regimen?
BPaLM is a shorter, all-oral medication regimen consisting of bedaquiline, pretomanid, linezolid, and moxifloxacin used to treat MDR/RR-TB.
How long is the new shorter treatment duration?
The shorter treatment courses are generally expected to last between 6 to 9 months.
Why are all-oral regimens preferred over traditional ones?
All-oral regimens avoid the use of injectable aminoglycosides, which are associated with higher toxicity and more severe adverse effects.
Who manages the approval of high-cost TB drugs in the UK?
Approval and guidance are coordinated through specialist clinical networks, including the British Thoracic Society and the Clinical Advice Service, with support from NHSE.
