OPRA Exam Pattern and Structure- Complete Details

Updated At: 2025-03-194 mins read

Key Takeaways

  • Unlike the KAPS examination, the OPRA exam has more focus on therupetics and real-world application of pharmaceutical knowledge. 

  • The main topics in the OPRA exam include biomedical sciences, medicinal chemistry and biopharmaceutics, pharmacokinetics and pharmacodynamics, pharmacology and toxicology and therapeutics and patient care. 

  • The OPRA exam is a single-paper which candidates need to complete in not more than 2.5 hours.

Introduction

An effective preparation for the OPRA exam begins with a clear understanding of the OPRA syllabus and pattern. Based on the topic distribution, you can plan a strategy which can lead to success in the OPRA exam. For your better understanding, we have drawn out the OPRA exam syllabus and pattern in the form of tables. Read the blog till the end and note down the syllabus to kickstart an effective OPRA exam study plan.

Solubility

Factors affecting solubility, dissolution, partition, and thermodynamics of pharmaceutical solutions.

Drug formulation

 

Materials and methods used in the formulation of drug delivery systems for common routes of administration, including oral, pulmonary, transdermal, parenteral, ophthalmic, nasal, rectal, and vaginal.

Pharmaceutical Microbiology

Preservation, antimicrobial agents, and sterilisation processes.

Pharmacokinetics and Pharmacodynamics

Content assessed

Topics

Drug metabolism

 

Chemical and biochemical basis for drug action and pathways for drug metabolism, drug absorption, disposition, biotransformation, elimination, receptor theory, signal transduction mechanisms, and molecular pharmacology.

Principles of pharmacokinetics

Bioavailability and bioequivalence, biological half-life, elimination and clearance concepts, distribution, protein binding, steady state considerations.

Factors affecting drug impacts

Determinants of drug onset, drug duration, and effect of factors such as disease/conditions and diet on absorption, distribution, metabolism, and excretion.

Evaluation of pharmacokinetic data

Kinetics of drug interactions, drug concentration vs time curves and interpretation of pharmacokinetics of low-therapeutic-index drugs.

Using pharmacokinetic data in treating patients

Use of pharmacokinetics to calculate, evaluate, and individualise drug therapy, including monitoring and adjustment of doses in renal and hepatic dysfunction, loading and time to reach a steady state.

Pharmacology and Toxicology

Content assessed

Topics

Impact of drugs on the body

Effects of drugs on organs and body systems, dose-response relationships, agonists, partial agonists, antagonists, enzyme inducers/substrates/inhibitors, genetic polymorphism, and clinical relevance.

Receptor theory

Drug receptor interactions, agonists/antagonists, dose-response curves, desensitisation, and super sensitivity.

Mechanisms of action of drugs

 

Mechanisms of action of various drug categories as they relate to organs and disease states. Including but not limited to central nervous system pharmacology, cardiovascular pharmacology, haemostasis and thrombosis, cancer chemotherapy, antihypertensives, and drugs for dyslipidaemia.

Adverse drug reactions

Adverse drug reactions, side effects of medicines and management and mechanisms of drug-drug interactions.

Drug interactions

Drug-drug interactions, drug-receptor interactions, drug-receptor binding, enzyme-substrate relationships, hydrophilic and hydrophobic interactions.

Drug toxicity and treatment

Drug and chemical overdose and antidotes. Signs and symptoms of toxicity and mechanism of toxicity and its management.

Factors causing changes in the pharmacology and toxicity of drugs

Modulators of drug pharmacology and toxicity include pharmacologic factors (disposition, biotransformation, renal elimination), physiological factors (age, sex, genetics, pregnancy, etc), and pathophysiological factors (liver disease, renal dysfunction).

Therapeutics and Patient Care

Content assessed

Topics

Screening

Calculation of common patient assessment parameters such as body mass index (BMI) and creatinine clearance.

Dose calculations

 

Amount of drug, number of doses, dosing based on body weight/ body surface area/ age/or other pharmacokinetic parameters, ratio and proportion, percentage, stock solutions, dilution and concentration, allegation, electrolyte solutions (milliequivalents/milliosmoles), reconstitution, infusion flow rates, isotonicity.

Primary health care

Selection of appropriate management options for treating illness and maintaining health and identification of circumstances where non pharmacological treatment is more appropriate.
