Description.  This standard provides for all routes of administration for drugs. 

Source.  COMIS Reference table (which is used by the Drug Product Reference File to generate Approved Drug Products with Therapeutic Equivalence Evaluations (a.k.a. "The Orange Book")), and the Drug Registration and Listing Database, Office of Epidemiology and Biosurveillance Database.  Also, the names (but not the definitions or the numeric codes) that are represented in blue have been harmonized with the E2B route of administration terms for the International Conference on Harmonization (ICH).


FDA Specifications.  None.

CDER Specifications.  Route of Administration shall consist of an alphabetic term which has a maximum length shall be restricted to 60 characters, with the hyphen and virgule being only punctuation permissible.  Codes representing these Routes of Administration shall consist of three digits.  In addition, since the prefixes intra- and endo- both mean within, the NSC generally felt that most US clinicians prefer the intra- prefix rather than the endo- prefix for route terms, with some exceptions (e.g., endotracheal).  Some general terms (e.g., parenteral) should be reserved for instances when a particular route of administration is unknown (e.g., MedWatch forms).  When possible E2B terms should take precedence.

FDA Approved Date.  None.

CDER Approved Date.  April 14, 1992
