          - 21 CFR Part 522

# AGENCY:

Food and Drug Administration, HHS.

# ACTION:

Final rule; technical amendment.

# SUMMARY:

                        The Food and Drug Administration (FDA) is amending a final rule that appeared in the                         **Federal Register**                         of January 4, 2007 (72 FR 263), revising the animal drug regulations to reflect approval of an original new animal drug application (NADA). The document incorrectly listed the amount of drug per milliliter of dexmedetomidine hydrochloride injectable solution. This action is being taken to improve the accuracy of the regulations.                    

# DATES:

This rule is effective April 20, 2007.

# SUPPLEMENTARY INFORMATION:

FDA has discovered that an error has been incorporated into the agency's regulations for 21 CFR part 522. This document corrects that error. Publication of this document constitutes final action under the Administrative Procedure Act (5 U.S.C. 553). FDA has determined that notice and public comment are unnecessary because this amendment is nonsubstantive.
