PharmacologyChurchill Livingstone, 1999 - 830 pagine The aim of this work is not only to describe what drugs do, but to emphasize the mechanisms by which they act - where possible at the cellular and molecular level. Therapeutic agents have a high rate of obsolescence and many new ones are introduced each year; an appreciation of the mechanisms of action of the class of drugs to which a new agent belongs provides a starting point for understanding and using intelligently. |
