    3.0 COURSE DETAILS

    3.1 Course Content: Metabolic factors affecting chemotherapeutic agents.Theories of the mechanism of drug action. Drug resistance and factors affectingdrug efficacy. Physiological and biochemical action of selected drugs. Traditional,medicinal plants in the management and therapy of common ailments; malaria,sickle-cell anaemia. General Toxicology.

    30h (T); 45h (P); R.

    3.2 Course Description: The course is designed to introduce students to drugtherapy and its effectiveness as well as a detailed knowledge of the actions anddisposition of drugs in mammals. The contents are in such a way to help studentsunderstand the mechanisms responsible for pharmacologic actions and for thedevelopment of resistance or tolerance to drugs. Factors affecting drug efficacysuch as resistance, routes of administration, species, genetic factors, age and sexe.t.c are also considered. Metabolism of xenobiotics in the liver and other tissuesare considered to gain further insight into the success or failure of a drug, whenused in a particular patient. The importance of traditional and medicinal plants inthe management and therapy of common ailments; malaria, sickle-cell anaemia arealso emphasized. The students will understand the importance of toxicology(observations of clinical and pathological changes that accompany theadministration of drugs) in the development of rational pharmacologic strategies toreduce or circumvent undesirable sequela to therapy.

    3.3 Course Justification: Increasingly, humans are exposed to various foreignchemicals (xenobiotics)-drugs, food additives, pollutants, e.t.c. It is thus importantfor students of Biochemistry to understand how xenobiotics are handled at thecellular level as well as learning how to cope with the chemical onslaught.Knowledge of the mechanisms of action and metabolism of xenobiotics is basic to

    the B.Sc. (Biochemistry) is for the students to understand and be able to describexenobiotic biotransformation, effective drug therapy and observations of clinicaland pathological changes that accompany exposure to xenobiotic as well as to beable to identify and understand the active ingredients in medicinal plants so as toimprove traditional medical practice.

    At the end of the course, the students should be able to

    describe and establish the mechanisms responsible for pharmacologicactions.

    describe and establish the mechanisms responsible for thedevelopment of resistance or tolerance to drugs.
