Pharmaceutical Care

Introduction

Health is defined as a state of complete physical, mental, and social well-being and not merely the absence of disease.

Medicines are used to treat, prevent, and manage various diseases. When used appropriately, medicines provide therapeutic benefits and improve patients' health. However, inappropriate use of medicines can cause harm, lead to adverse drug reactions, treatment failure, and increase healthcare costs for both patients and governments.

Pharmacists worldwide provide professional services in community, hospital, and clinical settings. Owing to their expertise in therapeutics and clinical pharmacy, pharmacists can identify drug-related problems, provide appropriate solutions, counsel patients on the safe use of medicines, and educate them about diet and lifestyle modifications to maximize therapeutic outcomes.

Pharmaceutical Public Health is the application of pharmaceutical knowledge, skills, and resources to prevent disease, prolong life, and promote, protect, and improve the health of society in an organized manner.

• Pharmaceutical Public Health focuses on health issues at the community/societal level.
• Pharmaceutical Care focuses on health issues at the individual patient level.

Pharmaceutical Care

The term "Pharmaceutical Care" was first coined by Mikeal et al. (1975) and defined as:

"The care that a given patient requires and receives which assures safe and rational drug use."

In 1990, Douglas C. Hepler and Linda M. Strand proposed a new definition that gained worldwide acceptance:

"The responsible provision of drug therapy for the purpose of achieving definite outcomes that improve a patient's quality of life."

This definition is more patient-centered and outcome-oriented, particularly for chronic diseases such as diabetes, hypertension, and asthma, where maintaining quality of life is essential.

In 1998, the International Pharmaceutical Federation (FIP) adopted this definition.

Difference Between Traditional Pharmacy Practice and Pharmaceutical Care

Traditional Pharmacy Practice

• Dispensing medicines based on prescriptions.
• Limited involvement in patient follow-up.

Pharmaceutical Care Practice

• Reviews and analyzes prescriptions.
• Identifies Drug-Related Problems (DRPs).
• Resolves DRPs in consultation with physicians and patients.
• Monitors therapeutic outcomes.
• Provides patient counseling and education.
• Focuses on improving quality of life and therapeutic outcomes.

Goal of Pharmaceutical Care

To ensure that patients receive:

• Appropriate drug therapy
