Modern hospital pharmacy practice extends far beyond drug dispensing. Today, pharmacists play a vital role in financial planning, clinical decision-making, and rational self-medication guidance. Unit 4 highlights three critical domains of hospital and community pharmacy practice: budget preparation and implementation, clinical pharmacy, and over-the-counter (OTC) drug sales. Together, these areas ensure cost-effective healthcare delivery, improved therapeutic outcomes, and patient safety.

Budget Preparation and Implementation in Hospital Pharmacy
Importance of Budgeting in Healthcare
Budgeting is a systematic financial planning process that ensures the optimal utilization of limited healthcare resources. In a hospital pharmacy, the budget directly influences drug availability, procurement efficiency, staffing, and service quality. Rising drug costs and expanding treatment options make budgeting a critical managerial responsibility.
Steps in Budget Preparation
Budget preparation begins with assessment of previous expenditures, analysis of drug consumption patterns, patient load, and disease prevalence. Future requirements are estimated by considering factors such as new drug introductions, inflation, seasonal disease trends, and expansion of hospital services. Pharmacists collaborate with hospital administrators, finance departments, and clinicians to create realistic and flexible budgets.
Implementation and Control
Once approved, budget implementation requires continuous monitoring and control. Periodic reviews help identify deviations, prevent wastage, and optimize inventory levels. Pharmacists use tools such as ABC–VED analysis, inventory turnover ratios, and cost-minimization strategies to ensure financial discipline without compromising patient care. Effective budget implementation directly improves hospital sustainability and drug availability.
Clinical Pharmacy: A Patient-Centered Approach to Drug Therapy
Introduction to Clinical Pharmacy
Clinical pharmacy is a patient-oriented discipline focused on optimizing drug therapy and improving health outcomes. Unlike traditional pharmacy practice, clinical pharmacy integrates pharmacological knowledge with direct patient care and therapeutic decision-making.
Concept and Scope
The core concept of clinical pharmacy is pharmaceutical care, which involves identifying, preventing, and resolving drug-related problems. Clinical pharmacists work alongside physicians and nurses to ensure safe, effective, and individualized medication therapy.
Functions and Responsibilities of a Clinical Pharmacist
Drug Therapy Monitoring
Clinical pharmacists play a crucial role in drug therapy monitoring, ensuring that prescribed medications achieve desired outcomes with minimal adverse effects. This includes reviewing medication charts for appropriate drug selection, dose, frequency, and duration.
Medication Chart Review and Clinical Review
Medication chart reviews help detect drug interactions, contraindications, duplications, and dosing errors. Clinical review involves evaluating patient-specific factors such as renal or hepatic function, age, and comorbidities to tailor therapy accordingly.
Pharmacist Intervention
When drug-related problems are identified, pharmacists intervene by recommending dose adjustments, alternative therapies, or additional monitoring. These interventions enhance patient safety and reduce medication errors.
Participation in Ward Rounds
Participation in ward rounds allows pharmacists to engage in real-time clinical discussions. This improves communication with healthcare teams and ensures evidence-based decision-making at the bedside.
Medication History and Pharmaceutical Care
Accurate medication history collection helps identify previous drug use, allergies, and adherence issues. Based on this information, pharmacists design pharmaceutical care plans that support continuity of care and improved outcomes.
Dosing Patterns and Pharmacokinetics-Based Therapy
Individualized Drug Dosing
Clinical pharmacists apply pharmacokinetic principles to adjust dosing regimens based on absorption, distribution, metabolism, and excretion. This is particularly important for drugs with narrow therapeutic indices, such as anticoagulants and antiepileptics.
Disease-Specific Therapy
Dosing patterns are modified according to disease states such as renal failure, hepatic impairment, or critical illness. Pharmacokinetic-based dosing ensures maximum efficacy with minimal toxicity, making therapy safer and more precise.
Over-the-Counter (OTC) Sales and Rational Drug Use
Introduction to OTC Medications
OTC drugs are medicines available without a prescription and are commonly used for self-care in minor ailments such as headache, cold, fever, acidity, and allergies. While convenient, improper OTC use can lead to adverse effects and drug interactions.
Role of the Pharmacist in OTC Sales
Pharmacists act as gatekeepers of rational self-medication. They assess patient symptoms, recommend appropriate OTC products, provide usage instructions, and refer patients to physicians when necessary. This role is essential in preventing misuse and masking of serious diseases.
Rational Use of Common OTC Medications
Rational OTC use involves correct drug selection, proper dose, and limited duration. Pharmacists educate patients on possible side effects, contraindications, and interactions with prescription medicines. Special caution is required in children, pregnant women, elderly patients, and individuals with chronic illnesses.
