Clinical pharmacists work directly with physicians and care teams to review patient medications, identify interactions, adjust therapy, and support treatment planning. They interpret lab values, monitor drug efficacy, manage high-risk medications, and participate in antimicrobial stewardship. Their work spans ICUs, internal medicine, oncology, cardiology, and ambulatory clinics. They rely on pharmacokinetic calculations, clinical guidelines, EMR systems, and patient-focused interventions. Increasing global adoption of clinical pharmacy models drives demand for advanced pharmacotherapy expertise and residency-trained professionals.
