Semester 8
BP810 ET. PHARMACOLOGICAL SCREENING METHODS
Scope: This subject is designed to impart the basic knowledge of preclinical studies in experimental animals including design, conduct and interpretations of results.
Objectives: Upon completion of the course the student shall be able to,
- Appreciate the applications of various commonly used laboratory animals.
- Appreciate and demonstrate the various screening methods used in preclinical research
- Appreciate and demonstrate the importance of biostatistics and research methodology
- Design and execute a research hypothesis independently
Unit –I
Laboratory Animals:
Study of CPCSEA and OECD guidelines for maintenance, breeding and conduct of experiments on laboratory animals, Common lab
animals: Description and applications of different species and strains of animals. Popular transgenic and mutant animals. Techniques for collection of blood and common routes of drug administration in laboratory animals, Techniques of blood collection and euthanasia.
Unit –II
Preclinical screening models
a. Introduction: Dose selection, calculation and conversions, preparation of drug solution/suspensions, a grouping of animals and importance of sham negative and positive control groups. The rationale for the selection of animal species and sex for the study.
b. Study of screening animal models for Diuretics, nootropics, anti-Parkinson’s, antiasthmatics, Preclinical screening models: for CNS activity- analgesic, antipyretic, anti-inflammatory, general anesthetics, sedative and hypnotics, antipsychotic, antidepressant, antiepileptic, antiparkinsonian, Alzheimer's disease
Unit –III
Preclinical screening models: for ANS activity, sympathomimetic, sympatholytics, parasympathomimetics, parasympatholytics, skeletal muscle relaxants, drugs acting on eye, local anesthetics
Unit –IV
Preclinical screening models: for CVS activity- antihypertensive, diuretics, antiarrhythmic, antidyslepidemic, antiaggregatory, coagulants, and anticoagulants
Preclinical screening models for other important drugs like antiulcer, antidiabetic, anticancer and antiasthmatics.
