Pharmacology Introduction: Introduction |  |
| Once a diagnosis has been made and medical treatment is deemed necessary, safe and effective pharmacologic agents that exert the appropriate actions should be selected. Factors to be considered include dose and frequency of administration of the chosen drugs, the optimal routes for delivery, the particular pharmaceutical forms to be used, any public health or environmental implications, and regulatory constraints. For selected therapies, such as antimicrobials, distribution to the
site of action also should be considered. |
| Although the Animal Drug Medicinal Use Act of 1994 legalizes extra-label drug use in the USA, selected states or other countries may have additional or complementary regulatory or legal restrictions. In all instances, it is important to read carefully the label instructions for use of specific drugs. |
