Dosage Form

FDA Data Element Number.  None.

CDER Data Element Number.  C-DRG-00201

Data Element Name. Dosage Form.

Data Element OID: 2.16.840.1.113883.3.26.1.1.2
Data Element NCI Concept ID: C42636

Version Number.  008

Description. This standard provides for all drug dosage forms.  The granularity of data often requires that more specific dosage form terms be stored in automated databases than are represented in publications.  These dosage form terms are available not only for use in databases that track approved drug products, but also for drug products such as: those that have not been approved, investigational drug products, homeopathic drug products, biologic products, veterinary drug products, and bulk drug products.  A ‘use restrictions’ column is being added to help identify where a particular dosage form set or subset should be used (a=CDER Databases, b=NDC Directory, c=Orange Book).

The definitions for Lotion, Cream, Ointment, and Paste were revised on June 21, 2006 to include information that would assist the user in differentiating between these dosage forms.  These changes were the result of discussions during an FDA Advisory Committee with an open public forum, scientific studies that were published in refereed pharmaceutical journals, and internal discussions by Agency personnel, including the usual adherence to the criteria that are specified in MaPP 7600.4.

A 1999 Food and Drug Administration Draft Guidance for Industry states: "A dosage form is the way of identifying the drug in its physical form.  In determining dosage form, FDA examines such factors as (1) physical appearance of the drug product, (2) physical form of the drug product prior to dispensing to the patient, (3) the way the product is administered, (4) frequency of dosing, and (5) how pharmacists and other health professionals might recognize and handle the product."

Footnotes:
1 A liquid is pourable; it flows and conforms to its container at room temperature.  It displays Newtonian or pseudoplastic flow behavior. 
2 Previously the definition of a lotion was “The term lotion has been used to categorize many topical suspensions, solutions, and emulsions intended for application to the skin.”  The current definition of a lotion is restricted to an emulsion. 
3 A semisolid is not pourable; it does not flow or conform to its container at room temperature.  It does not flow at low shear stress and generally exhibits plastic flow behavior.
4 A colloidal dispersion is a system in which particles of colloidal dimension (i.e., typically between 1 nm and 1 µm) are distributed uniformly throughout a liquid. 
5 Percent water and volatiles are measured by a loss on drying test in which the sample is heated at 105°C until constant weight is achieved.
