Pharmacology and Pharmacokinetics (E07U0A)
The following subjects will be covered:
Introduction to pharmacology: Development (incl. notions of 'rational drug design'), evaluation and testing of new drugs (e.g. bioassay), brief overview of registration procedure and refunding.
Pharmacokinetics: Insights in kinetic processes of absorption, distribution and elimination, biotransformation/metabolism of drugs.
Pharmacodynamics and receptors (basics since receptor mechanisms are addressed extensively in cell biology and biochemistry).
Toxicology (introductory): General principles, toxicity of drugs: mechanisms
Pharmacology, with special attention to mechanisms of action of the different groups of pharmacological agents (no individual drugs will be discussed) related to: The autonomous and peripheral nervous system, the central nervous system, the cardiovascular system, the endocrine system, pain, fever and inflammation.
Cytostatics, biotechnological drugs (monoclonal antibodies).
Final examination during examination period, closed book. Each student will do the complete exam with one of the course lecturers.
Oral with written preparation: 4 questions, the questions will include: 1. An open question. 2. Explanation of a case report or an article concerning the use of (a) drug(s). 3. Two questions with different parts/topics for which situation/explanation/justification of the answer is expected.
A minimum of 60 minutes is provided for written preparation of the exam. Afterwards the students can present themselves to the designated examiner for the oral part of the exam. All documents (including preparatory documents) have to be handed over to the examiner or the observer.

Exam questions '11-'12
1) Discuss the (nor)adrenergic synapse and the effect that different classes of drugs have on it.
2) A girl (15) is brought into the ER with the following symptoms: dizziness, headache, flushing, blurred vision, polyuria, polydipsia, attention deficit. Diabetes mellitus and diabetes insipidus have been ruled out. A medical history reveales the use of dexchlorfeniramine, an antihistamine. a) Explain the symptoms and give other symptoms related to antihistamines. b) Give possible indications for the prescription of this drug.
3) For the following drugs, give the working mechanism, receptor class and therapeutical use. For the working mechanism, choose from: irreversible inhibitor, competitive antagonist, non-competitive antagonist, agonist, reuptake inhibitor. Fentanyl, verapamil (CCB), simvastatin, leptocurare, benzodiazepines, ondansetron, metoclopramide, aspirin, venlafaxine (SNRI), naloxone
4) Right or wrong? Explain a) Xylocain is a good local anaesthetic for a tooth abcess b) TDM is needed for treatment with i) digoxin, ii) coumarins, iii) lithium c) Strong anti-emetics such as ondansetron and domperidone can pass the blood brain barrier d) Varenicline, a drug used in smoking cessation, is an antagonist of the muscarinic acetylcholine receptor e) fluoxetine and erythromycine have no effect on CYP metabolism
Exam questions '12 - 13'
1. General questions
Explain the side effects of NSAID's using their mechanism of action.
Give the autonomic effects of morphine. Give and explain the differences with pentazocine.
Explain the (nor)adrenergic synaps and discuss the effect on it by different classes of drugs.
2. Case study
Case, female, 15 years old, presents itself with dizzyness, blurred vision(accommodation disorder due to antimuscarinic effects), head ache, polydipsia and plyuria. She recieved an anti-histaminic earlier. Explain the side effects, which symptoms are expected and why she was prescribed an anti-histaminic.
3 patients with long QT-syndrome and asthma. Explain the use treatment for both conditions (beta-blockeers vs beta agonists) and the additional treatments for asthma.
Discuss the pharmacological components: A 40 year-old woman with schizoaffective disorder is treated with haloperidol and lithium. The lithium is replaced with carbamazepine. This results in deterioration of the patient, which disappears after dicontinuation of carbamazepine treatment. Blood test reveal altered haloperidol blood levels. This pharmacokinetic interaction has to be further investigated.
Opioids interfere with p.o. drugs; Atenolol, verapamil and alphablockers reduce Heart Rate; Antimuscarinica, CA-I en ß-blockers are used for glaucoma; Ezetimibe is an add-on drug Gucocorticoid treatment should not be stopped abruptly Depressed people with prostate hypertrophy should be treated with TCAs Reserpine can cause lowered heart rate and depression These drugs cause increased heart rate: i. Verapamil ii. Nifedipine iii. alpha1-blockers Ibuprofen is anti-indicated in heart failure Codeine can be used as an analgesic in patients with gastric ulcer Nifedipine, captopril, propanolol and nitroglyceride are drugs that decrease the heart rate Xylocaine can be used as an analgesic in patients with tooth abcesses 5mg of drug A has the same effect as 500 mg of drug B, this means drug A is more toxic than drug B and drug B has a shorter duration of action than drug A
4. Explain the interactions
haloperidol and ropinirol; captopril and spironolactone; cortisone and naproxen; alcohol and benzodiazepines; lithium and a low salt diet; alcohol and a benzodiazepam; fenytoine and fluvoxamine/fluoxetine; ezetimibe and a simvastatin
5.Give the mechanism of action, the receptor class and therapeutic use of the following drugs: Ondansetron, metoclopramide, fentanyl,...
Exam questions '13 - 14'
Discuss the benefits of ACE-inhibitors in heart failure
discuss the noradrenergic synaps and different drugs that act on it
Beta blockers indications and contra indications (plus diabetes, asthma and pregnancy)
Case: diabetic woman with manic attack who was treated with several anti-epileptics.
Case: A girl (15) is brought into the ER with the following symptoms: dizziness, headache, flushing, blurred vision, polyuria, polydipsia, attention deficit. Diabetes mellitus and diabetes insipidus have been ruled out.
