Case studies accompany most chapters, and answers to questions posed in the case studies appear at the end of each chapter.
The book is designed to provide a comprehensive, authoritative,
and readable pharmacology textbook for students in the health
sciences. Frequent revision is necessary to keep pace with the rapid
changes in pharmacology and therapeutics; the 2–3 year revision
cycle of this text is among the shortest in the field, and the availability of an online version provides even greater currency. The
book also offers special features that make it a useful reference for
house officers and practicing clinicians.
This edition continues the sequence used in many pharmacology courses and in integrated curricula: basic principles of drug
discovery, pharmacodynamics, pharmacokinetics, and pharmacogenomics; autonomic drugs; cardiovascular-renal drugs; drugs
with important actions on smooth muscle; central nervous system
drugs; drugs used to treat inflammation, gout, and diseases of
the blood; endocrine drugs; chemotherapeutic drugs; toxicology;
and special topics. This sequence builds new information on a
foundation of information already assimilated. For example, early
presentation of autonomic nervous system pharmacology allows
students to integrate the physiology and neuroscience they have
learned elsewhere with the pharmacology they are learning and
prepares them to understand the autonomic effects of other drugs.
This is especially important for the cardiovascular and central nervous system drug groups. However, chapters can be used equally
well in courses and curricula that present these topics in a different
sequence.
Within each chapter, emphasis is placed on discussion of drug
groups and prototypes rather than offering repetitive detail about
individual drugs. Selection of the subject matter and the order
of its presentation are based on the accumulated experience of
teaching this material to thousands of medical, pharmacy, dental,
podiatry, nursing, and other health science students.
Major features that make this book particularly useful in
integrated curricula include sections that specifically address the
clinical choice and use of drugs in patients and the monitoring of
their effects—in other words, clinical pharmacology is an integral
part of this text. Lists of the trade and generic names of commercial preparations available are provided at the end of each chapter
for easy reference by the house officer or practitioner evaluating a
patient’s drug list or writing a prescription.
Significant revisions in this edition include:
• Major revisions of the chapters on immunopharmacology,
antiseizure, antipsychotic, antidepressant, antidiabetic, antiinflammatory, and antiviral drugs, prostaglandins, and central

SLEEP & ITS DISTURBANCES, UNCONSCIOUSNESS.pptx
Sleep is a complex rhythmic state involving repeated cycles of different brain and body activity phases crucial for well-being. Unconsciousness is a stage of depressed cerebral function causing impaired response and awareness for an uncertain time. This document discusses sleep physiology and cycles, factors affecting sleep, common sleep disturbances and their management, as well as defining unconsciousness, its causes, manifestations, diagnostic assessment, and management including symptomatic and surgical treatments and potential complications.
Learning under stress .
Stress can impact learning and memory. Moderate stress may enhance learning through increased arousal and attention, but high stress can impair memory formation. The hormone cortisol, released during stress, can damage hippocampal neurons and interfere with the conversion of short-term to long-term memory. However, learning may still occur under stress if the stressful event and material to be learned converge in space and time. Neuroimaging studies show that chronic stress deteriorates memory by damaging the hippocampus.
