DHA Pharmacist Exam study guide
DHA Pharmacist Exam · Work through your exam, one topic at a time.
The DHA Pharmacist Exam is the licensure assessment used by the Dubai Health Authority for pharmacists who wish to register and practise in the Emirate of Dubai. It is aimed at pharmacy graduates - whether trained inside the UAE or abroad - who need to demonstrate that their knowledge meets the standard expected of a practising pharmacist in Dubai's healthcare system. The DHA Pharmacist Exam study guide has 7 sections and about 2,709 words.
01Pharmacology and Therapeutics
Pharmacodynamics is what the drug does to the body: receptor binding, agonist / partial agonist / inverse agonist behaviour, competitive versus non-competitive antagonism, potency (EC50) versus efficacy (Emax), and the therapeutic index that separates effective from toxic exposure. Pharmacokinetics is what the body does to the drug: absorption and bioavailability (F, first-pass effect), distribution (volume of distribution, protein binding), metabolism (phase I CYP450 oxidation, phase II conjugation), and excretion.

Practice questions test whether you can move from dispensing to a documented care process: collect a best-possible medication history, reconcile at admission and discharge, identify drug-related problems (indication, effectiveness, safety, adherence), set a plan, and monitor outcomes. The SOAP note (Subjective, Objective, Assessment, Plan) is the usual documentation format, and the care plan must name the specific parameter to monitor and its frequency.

Pharmaceutics links formulation to bioavailability. Key concepts: dissolution rate (Noyes–Whitney, surface area and solubility dependent), the Biopharmaceutics Classification System (Class I high solubility/high permeability, Class II low solubility/high permeability = dissolution-rate limited, Class III high solubility/low permeability = permeability limited, Class IV both low), excipient function (diluent, binder, disintegrant, glidant, lubricant, coating), and the difference between immediate-, delayed- and extended-release systems.

Functional groups predict ionisation, solubility and receptor fit. Carboxylic acids and amines ionise according to pKa, and the Henderson–Hasselbalch relationship tells you the ionised fraction at a given pH.

Bacteria are classified by Gram stain (peptidoglycan thickness), shape, oxygen requirement and biochemical profile. Mycobacteria are acid-fast due to mycolic acids and do not Gram-stain reliably; Pseudomonas aeruginosa is a non-fermenting Gram-negative rod; MRSA is methicillin-resistant Staphylococcus aureus via altered PBP2a.

Know the approval pathways: a full New Drug Application with clinical evidence, an ANDA for generic equivalence (same active ingredient, strength, dosage form, route, quality and bioequivalence), and a 505(b)(2) pathway relying partly on existing literature. Over-the-counter products may follow a monograph system.

Primary literature reports original research (randomised trials, cohort studies, case reports). Secondary literature indexes and abstracts primary sources (PubMed/MEDLINE, Embase, International Pharmaceutical Abstracts, Cochrane CENTRAL).
