Final answer:
Pharmacists can provide DTM as part of a collaborative care plan to manage complex, personalized medication regimens for chronic conditions and ensure medications are within therapeutic ranges, such as in DOT for TB, where WHO recommends supervised treatment.
Step-by-step explanation:
A pharmacist can provide Direct Therapy Management (DTM) under a prescriber care plan in several instances, particularly when personalized medication management is essential. This is often the case with complex therapies for chronic diseases like diabetes, wherein medications like human insulin are tailored according to individual needs. As outlined in pharmacotherapy guidelines, DTM allows pharmacists to work within a collaborative practice agreement with the prescriber, optimizing patient-specific medication regimens based on factors such as age, weight, genetic polymorphism, comorbid diseases, and potential drug-drug interactions (DDI).
Additionally, Therapeutic Drug Monitoring (TDM) is a critical component in adjusting dosages to achieve optimal therapeutic ranges, thereby maximizing drug efficacy and minimizing adverse effects. This approach is particularly important for antibiotics to prevent resistance, for example in directly observed therapy (DOT), which is integral to treating TB effectively as per WHO's global strategy. As healthcare evolves, with technology enabling advancements like home delivery of insulin, the role of pharmacists in patient care continues to expand beyond traditional dispensing functions.
