INTRODUCTION

ABBREVIATION INTERPRETATION NDC NATIONAL DRUG CODE NEC NOT ELSEWHERE CLASSIFIED Descriptive comments are included only when the classification system itself is not self-explanatory. The VA Drug Classification system classifies drug products, not generic ingredients. Drug products with local effects are classified by route of administration (e.g., dermatological, ophthalmic). If a product is not classified by route of administration, it is classified in most instances under a specific chemical or pharmacological classification (e.g., beta-blockers , cephalosporins). If a product is not classified by route of administration, or chemical or pharmacological subclassification, it may be classified under a therapeutic category (e.g., antilipemic agents, antiparkinson agents). Most combination products are found in the "other" subclassification under each major classification unless a specific subcategory for combination products exists or a descriptive comment indicates inclusion elsewhere. In addition, products which are not adequately described by a minor category or subcategory within the major classification are classified as "other" (e.g., metronidazole, vancomycin). The "notes" included in the following classification file define assignment of codes for primary classifications only. These notes may or may not be applicable to any secondary classifications.
