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 Search Results
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
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.
The Drug Search Results screen displays search results by drug code, drug
name, generic name, and number of drug mentions (defined below) for the most
recent year of data. If number of mentions is blank, there were no recorded
entries for the drug that year. By clicking on any of the underlined text in the
Drug Search Results, information will be displayed on the drug's
characteristics, number of mentions, and mention rate.
Drug Mention: The 2005 estimate of drug mentions for each drug reported in
the 2005 NAMCS and NHAMCS is provided. A drug mention is the physician’s
entry on the survey collection form 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.
In 2005, as many as 8 drugs could be reported per ambulatory care visit. If no
figure is displayed, there were no mentions of that drug in 2005.
Drug Mention Rate: The drug mention rate is the number of mentions for a
particular drug code per 10,000 ambulatory medical care visits in 2005.
