D.PHARM (PARTI) SYLLABUS FOR PHARMACEUTICAL CHEMISTRYI

1. Introduction

The Diploma in Pharmacy (PartI) is the first stage of professional pharmacy education in many countries. Pharmaceutical ChemistryI lays the foundation for understanding the chemical principles that govern drug design, synthesis, and analysis. This page summarises the official syllabus, learning outcomes, recommended textbooks, and assessment pattern for the subject.

2. Course Objectives

• Introduce basic concepts of inorganic, organic and physical chemistry as applied to medicines.
• Develop the ability to interpret chemical structures, reactions and mechanisms relevant to drug molecules.
• Familiarise students with laboratory techniques for the preparation and analysis of pharmaceutical compounds.
• Instil a scientific approach to problem solving and critical evaluation of literature.

3. Detailed Syllabus

3.1 General Chemistry

• Atomic structure, electronic configuration and periodic trends.
• Bonding theories ionic, covalent, metallic and coordinate bonds.
• Acids, bases and pH; buffer systems in pharmaceutical preparations.
• Thermodynamics enthalpy, entropy, Gibbs free energy and their relevance to drug stability.

3.2 Organic Chemistry Fundamentals

• Hybridisation, molecular geometry and polarity.
• Functional groups classification, nomenclature and characteristic reactions.
• Reaction mechanisms nucleophilic substitution, electrophilic addition, elimination, oxidationreduction.
• Stereochemistry chirality, optical activity and its impact on pharmacological activity.

3.3 Pharmaceutical Organic Chemistry I

• Alkaloids structure, classification and basic extraction techniques.
• Phenols, phenolic acids and their derivatives; importance in analgesics and antipyretics.
• Aromatic substitution reactions (electrophilic and nucleophilic) with examples (e.g., synthesis of paracetamol).
• Carbonyl chemistry aldehydes, ketones, carboxylic acids, esters and amides with emphasis on drugrelated transformations.
• Heterocyclic systems basics of pyridine, pyrimidine, quinoline and their pharmaceutical relevance.

3.4 Physical Pharmacy Chemical Aspects

• Solubility and dissolution factors influencing drug solubility, partition coefficient (logP) and its significance.
• Diffusion, osmosis and membrane permeability.
• Stability chemical degradation pathways (hydrolysis, oxidation, photolysis) and methods of protection.
• Basic concepts of pharmaceutics dosage form selection based on chemical properties.

3.5 Laboratory Techniques

• Qualitative analysis identification of functional groups (e.g., Tollens test, FeCl test).
• Quantitative analysis titration, gravimetric determination, spectrophotometry.
• Thin layer chromatography (TLC) and paper chromatography for checking purity.
• Melting point determination, refractometry and basic spectroscopic techniques (UVVis).
• Safety practices handling of hazardous chemicals, use of personal protective equipment (PPE) and waste disposal.

4. Learning Outcomes

Upon successful completion of the course, a student will be able to:

1. Explain the relationship between chemical structure and pharmacological activity.
2. Predict the outcome of common organic reactions used in drug synthesis.
3. Analyse the physicochemical properties that govern drug absorption and stability.
4. Perform routine laboratory tests for purity and identity of medicinal substances.
5. Interpret data from spectroscopic and chromatographic instruments.

5. Recommended Textbooks & References

6. Assessment Scheme

7. Tips for Success

• Master the fundamentals of organic reaction mechanisms they recur throughout the syllabus.
• Regularly revise functionalgroup chemistry; use flash cards for quick recall.
• Practice drawing structures in both skeletal and expanded form to avoid mistakes in exams.
• Develop a systematic approach to lab work: plan, execute, record and interpret results.
• Read current pharmaceutical journals to see realworld applications of concepts learned.
