This is the pre-2006 version of the Ambulatory Care Drug Database, which used NCHS classification systems along with FDAâ€™s National Drug Code Directory for
coding drug characteristics. It is only useful for looking up drug characteristics in NAMCS and NHAMCS for data years prior to 2006.
For information about the current Ambulatory Care Drug Database, see the
New Ambulatory Care Drug Database System.

Guidance on Search Criteria:
Drug Code: A unique NCHS-assigned, 5-digit code applied to each
entry name mentioned in the NAMCS or NHAMCS.
Drug Name: The specific drug identifier entered by the physician. It
corresponds with the entry made on any prescription or
medical order. It may be either a trade/brand/proprietary or
generic name, but not a drug class.
Generic Code: A unique NCHS-assigned, 5-digit code applied to each
generic/nonproprietary/active ingredient name.
Generic Name: The official name assigned to every drug entity by the
United States Pharmacopeia/United States Adopted Names
or other responsible authorities. If the drug listed is a
combination medication, this entry will read “combination”
or “fixed combination” and will contain up to five active
Ingredient Code: A unique NCHS-assigned, codes used to identify the single
active ingredients of combination drugs. A maximum of 5
ingredients can be identified for each combination drug.
Ingredient Name: Used in combination products to identify an active ingredient.
Drug Mention:The 2002 estimate of drug mentions
for each drug mentioned in the 2002 NAMCS and NHAMCS
is provided. The drug mention rate is the number of mentions for that drug code
per 10,000 ambulatory medical care visits in 2002.
The physician’s entry of a pharmaceutical agent--by any
route of administration--for prevention, diagnosis, or
treatment. Generic as well as brand-name drugs are
included, as are nonprescription and prescription drugs.
Along with all new drugs, the physician also records
continued medications if the patient was specifically
instructed or expected to continue the medication.
NDC Class Category: A code used to identify each of 20 major classes to which
the drug entry may belong. (Adapted from Standard Drug
Classifications in the National Drug Code (NDC) Directory,
1995). The two-digit categories are general and represent
all sub-categories (e.g. Antimicrobial agents) and the
specific four-digit categories represent the breakouts of the
general category (e.g. Penicillin). The general two-digit
codes will include medications which do not fit into any of
the sub-categories (4-digit codes).
Prescription Status: A code designed to identify the Federal legal status
(prescription or nonprescription) of the drug entry.
Prescription drugs are also referred to as legend drugs.
Composition Status: A code used to distinguish between single active ingredient
drug product and a fixed active ingredient combination drug product. From this
point on a fixed active ingredient combination drug product will be
referred to as a combination drug.
DEA Status: Controlled medications, because of their significant
potential for dependence or abuse and their possible
diversion into illicit channels, are regulated under Federal
law by the Department of Justice, Drug Enforcement
Agency (DEA). The Controlled Substance Act of 1970
characterizes each controlled drug into one of five
schedules. Schedule I drugs, like heroin and LSD, have a
higher potential for abuse and no current accepted medical
usefulness for treatment in the United States. Each
successive schedule, II-V, reflects a decreasing degree of
dependence and potential for abuse.
