General Pharmacology and Pharmacognosy
A.Y. 2024/2025
Learning objectives
The course is structured in two modules: General Pharmacology and Pharmacognosy.
The main objective of the general Pharmacology module is to learn the bases necessary to understand the activity of the drugs, both of natural or synthetic origin. The course is intended to provide the student the bases of pharmacodynamics and pharmacokinetics while taking into account the most important neurotransmitters and their systems, from biogenic amines, to acetylcholine, from GABA to excitatory aminoacids and the arachidonic acid system.
The Pharmacognosy module will provide the student the basic knowledge about pharmacokinetic and pharmacodynamic of natural or synthetic biologically active molecules, with emphasis on how these processes will affect pharmacological activities of active compounds and their final therapeutic effects. This module will also explore more in detail pharmacologically active preparations from natural sources (with special emphasis on the preparations present in the European Pharmacopoeia), their active components and therapeutic applications.

Expected learning outcomes
At the end of the General Pharmacology module, the student should be familiar with the endogenous targets of the drugs (receptors, enzymes, pumps and transporters, ionic channels) and their relationship with the endogenous systems, such as sympathetic, parasympathetic, dopaminergic, serotoninergic, histaminergic, GABAergic, excitatory aminoacids as well as arachidonic acid system. In addition, students should have enough pharmacodynamics and pharmacokinetics notions to understand the function of active substances, both of natural or synthetic origin.For the Pharmacognosy module is expected that the student will acquire: knowledge of the mechanisms responsible for the absorption, distribution, metabolism and excretion of pharmacologically active molecules, either natural or synthetic; knowledge of the main pharmacokinetic parameters; knowledge of the main classes of pharmacological targets, with a specific focus on membrane and intracellular receptors; ability to evaluate the behavior of a pharmacologically active compound based on its pharmacokinetic and pharmacodynamic characteristics; knowledge of the pharmacologically active compounds and therapeutic activities of medicinal drugs/botanicals belonging to different chemical or therapeutic classes; ability to identify potential pharmacokinetic or pharmacodynamic interactions between drugs or botanicals/drugs.

Prerequisites for admission
The course is aimed at students of the Degree in Pharmacy who have acquired basic knowledge of biology. Prerequisites are the topics covered in the propaedeutical exams reported in the Manifesto of the degree course.
Teaching methods
The course will be delivered through lectures with the use of slides and the material of the lessons will be made available on ARIEL.
For the Pharmacognosy module, during the course a visit to the Botanical Garden Museum of Brera (Milan) will be organized. The museum contains a variety of medicinal and officinal plants. In this way, students will be able to view and study in detail the morphology and the drug of the medicinal plants occurring in the garden. When available, parts of plants studied during the teaching will be brought to the lessons, to make the recognition of the drugs more effective.
The frequency of teaching is strongly recommended.

Assessment methods and Criteria
The exam will be aimed at ascertaining the achievement of the objectives in terms of knowledge and understanding and verifying the student's autonomy of judgment. Mastery of the topic, expository and synthesis skills will also be evaluated. For the General Pharmacology Module, the assessment will take place through a written exam on the topics covered during the course. The test is structured with 23 multiple-choice questions. Each question is worth 1.5 points if the answer is correct, -0.75 if wrong and 0 for the answer not given. The Pharmacology module will be passed with a score of at least 18. The duration of the test will be 30 minutes.
For the Pharmacognosy Part, the exam will be held in written form and will take 60 minutes. The exam consists of 10 multiple-answered questions (with 3 possible answers, of which only one is correct), and 2 open questions on the topics addressed during the course. Each correct answer is worth 2 points for multiple answer questions, while the best score for answers to open-ended questions is 5 points.
The results of the tests will be communicated by e-mail within the deadlines indicated during the execution of the final exam. The student can request to view the assignment at any time. During the academic year there are 8 exam sessions. The overall grade, expressed in thirtieths (18-30), will derive from the weighted average of the two modules, General Pharmacology (4 CFU) and Pharmacognosy (6 CFU).

Assessment methods and Criteria
Two separate examinations will be organized for the two modules. The final mark will be the weighted average of the two marks.
A positive evaluation in the examination of the module of General Pharmacology is mandatory to sustain the examination of the module of Pharmacognosy, and the latter must be passed within 1 calendar year from the former.
Module of General Pharmacology
The examination will consist of a 30-minute written test based on 15 multiple-choice questions. Each question will give 2 points if the answer is correct and 0 points if the answer is incorrect or the question is left without an answer. The test will be passed with a minimum score of 18.
Module of Pharmacognosy
The examination will consist of an oral examination (about 20-minutes long colloquium); basic knowledge from the module of General Pharmacology will be fundamental for a positive outcome.
