What is Clinical Pharmacy?
Clinical pharmacy is an integral part of the healthcare system, encompassing all aspects of the relationship between medicines and people. As medicines are among the most important tools in the fight against health problems, ensuring their safe and effective use lies at the core of clinical pharmacy.
Equally, clinical pharmacy plays a critical role in identifying and managing potential problems caused by medications. In this sense, clinical pharmacy not only ensures the optimal delivery of healthcare services but also contributes significantly to their continuous development.
Unlike traditional pharmacy practices that focus primarily on dispensing and ordering medications, clinical pharmacy addresses clinical scenarios. This field covers a wide range of issues, from the composition and recommended dosages of medical products and devices, to optimizing patient care, and investigating potential adverse effects and risks of therapies.
The defining difference of clinical pharmacy compared to other branches of pharmacy is that patient benefit is always the primary priority. Organizing the patient’s medication regimen in the most optimal way for their health, and educating the patient on safe use, are essential elements within the scope of clinical pharmacy. Thus, clinical pharmacy is considered an indispensable part of every treatment process.
Why is Clinical Pharmacy Important?
Until the 1940s, traditional pharmacy practices predominated globally. However, with the rapid development of the pharmaceutical industry—particularly after the 1970s-pharmacy began to branch out into different specialized fields.
While large pharmaceutical companies took over the manufacturing of medicines, thereby reducing the demand for pharmacists in traditional roles, the need for services focused on patient perspectives emerged. Patient-specific factors such as medical history, prior treatments, and the compatibility of new medications with existing therapies must all be considered when designing safe treatment plans. This gap highlighted the necessity of clinical pharmacy.
Roles and Responsibilities of Clinical Pharmacists
Clinical pharmacists may work in hospitals, community pharmacies, home healthcare services, private clinics, the pharmaceutical industry, and nursing homes. Their responsibilities cover a broad spectrum, including:
Evaluating drug therapy and providing appropriate recommendations to the patient or physician.
Supplying evidence-based information on the safe and effective use of medications.
Identifying health problems that can be managed through pharmacological therapy.
Monitoring patients’ progress during drug therapy and suggesting adjustments when necessary.
Providing education and guidance to patients regarding proper drug use and dosage.
Preventing potential errors in medication use.
Ensuring patients receive the most appropriate treatment by considering existing health conditions, concurrent medications, and other factors.
Assisting with patient care in hospitals and surgical settings.
Supporting regulatory bodies in monitoring and advancing the pharmaceutical profession and industry.
When Are Clinical Pharmacists Needed?
Patients may consult clinical pharmacists directly for advice and guidance. Clinical pharmacists provide support in situations such as:
Long-term conditions (e.g., asthma, hypertension, arthritis, or type 2 diabetes) where information on medication effectiveness is required.
Identifying and managing potential adverse effects or drug-drug interactions.
Dose adjustments during long-term use, depending on efficacy and patient response.
Guidance on medications prescribed at hospital discharge and their safe continuation at home.
Clinical pharmacists do not replace family physicians or medical specialists. After consultation, they may refer patients to a physician when necessary. Physicians may also encourage patients to seek input from clinical pharmacists, particularly when analyzing complex drug regimens to prevent harmful interactions.
In summary, clinical pharmacy is a vital discipline within the healthcare system, dedicated to ensuring the safe and effective use of medications, identifying risks, and contributing to both the quality and advancement of healthcare services.
