Medical Pharmacology

Medical Pharmacology studies how medicines interact with the human body and with each other. The department supports clinical teams and patients by assessing drug effects, interaction risks, toxicity concerns and monitoring needs to promote safe medication use.

When to consult Medical Pharmacology

Medical Pharmacology is consulted when there are unexpected adverse reactions, suspected drug–drug interactions, concerns about toxicity, or questions about appropriate monitoring for specific medications. Clinicians may seek input before starting complex regimens, when managing patients on multiple drugs, or when laboratory results suggest possible drug-related effects. In life‑threatening or rapidly worsening symptoms, emergency services should be contacted first.

Assessing drug interactions and adverse effects

Interactions can change how well a medicine works or increase the chance of side effects. Specialists combine evidence from clinical literature, pharmacokinetic data and laboratory findings to identify likely interactions and advise on risk reduction. They also help determine whether a reported symptom is plausibly medication‑related and recommend appropriate next steps for assessment.

Monitoring, laboratory testing and dose considerations

Safe use of some drugs requires blood level checks, and assessment of kidney and liver function or other lab markers. Medical Pharmacology helps determine which tests are indicated, how to interpret results in context, and when dose adjustment or alternative therapy should be considered by the treating team. This guidance is especially important for older adults, people on multiple medicines, and those with chronic organ impairment.

Research, guideline support and education

The department contributes to clinical research, safety monitoring in trials, and the development of prescribing protocols. It also provides education for healthcare professionals on pharmacology principles, adverse event recognition, and best practices for minimizing medication‑related harm. Reviews of new medications and combination therapies are part of its remit.
