QV Pharmacology
	Classify here works on pharmacology in general or on the pharmacology of individual drugs or types of drugs grouped according to their specific action. Classify works on an individual drug according to its principal action. Classify works on the use of an individual drug in the treatment of a particular disease with the disease. Classify works on the purely chemical or technological use of chemicals in the QD or the T schedules. Classify a drug derived from a plant with the drug. Classify works on vitamins in QU; on endocrine preparations in WJ, WK, or WP; and non-endocrine biologicals in QW. Classify the abuse of a drug in the appropriate WM number. Note that occasionally agents are classed together because they are frequently treated together regardless of their different actions, e.g., sulfur and sulfur compounds in QV 265. Classify works dealing with the general aspects of pharmacy and pharmaceutics in the section beginning with QV 701. Note that Pharmacy and Pharmaceutics section also has many of the early range or form numbers found under Pharmacology.
