Guidance for Industry on Tablet Scoring: Nomenclature, Labeling, 
and Data for Evaluation; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is announcing the 
availability of a guidance for industry entitled ``Tablet Scoring: 
Nomenclature, Labeling, and Data for Evaluation.'' This guidance 
provides recommendations to sponsors of new drug applications (NDAs) 
and abbreviated new drug applications (ANDAs) regarding what criteria 
should be met when evaluating and labeling tablets that have been 
scored. (A scoring feature facilitates tablet splitting, which is the 
practice of breaking or cutting a higher-strength tablet into smaller 
portions.) Specifically, this guidance recommends guidelines to follow, 
data to provide, and criteria to meet and detail in an application to 
support approval of a scored tablet; and nomenclature and labeling for 
approved scored tablets.
    This guidance does not address specific finished-product release 
testing, where additional requirements may apply to scored tablets. 
This guidance does not describe the medical practice conditions under 
which tablet splitting is considered or recommended.

DATES: Submit either electronic or written comments on Agency guidances 
at any time.

ADDRESSES: Submit written requests for single copies of this guidance 
to the Division of Drug Information, Center for Drug Evaluation and 
Research, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 
51, Rm. 2201, Silver Spring, MD 20993-0002. Send one self-addressed 
adhesive label to assist that office in processing your requests. See 
the SUPPLEMENTARY INFORMATION section for electronic access to the 
guidance document.
    Submit electronic comments on the guidance to http://www.regulations.gov. Submit written comments to the Division of Dockets 
Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, 
Rm. 1061, Rockville, MD 20852.

Evaluation and Research (HFD-003), Food and Drug Administration, 10903

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a guidance for industry 
entitled ``Tablet Scoring: Nomenclature, Labeling, and Data for 
Evaluation.'' This guidance provides recommendations to sponsors of 
NDAs and ANDAs regarding what criteria should be met when evaluating 
and labeling tablets that have been scored. (A scoring feature 
facilitates tablet splitting, which is the practice of breaking or 
cutting a higher-strength tablet into smaller portions.) Specifically, 
this guidance recommends:
     Guidelines to follow, data to provide, and criteria to 
meet and detail in an application to support approval of a scored 
tablet; and
     Nomenclature and labeling for approved scored tablets.
    On August 30, 2011 (76 FR 53909), FDA announced the availability of 
the draft version of this guidance. The public comment period closed on 
November 28, 2011. A number of comments were received from the public, 
all of which the Agency considered carefully as it finalized the 
guidance and made appropriate changes. The Agency also held an Advisory 
Committee for Pharmaceutical Science and Clinical Pharmacology meeting 
on August 9, 2012, to discuss the draft guidance. Any changes to the 
guidance were minor and made to clarify statements in the draft 
guidance.
    The Agency has previously considered tablet scoring as an issue 
when determining whether a generic drug product is the same as the 
reference listed drug (RLD). One characteristic of a tablet dosage form 
is that it may be manufactured with a score or scores. This 
characteristic is useful because the score can be used to facilitate 
the splitting of the tablet into fractions when less than a full tablet 
is desired for a dose. Although there are

[[Page 15957]]

no standards or regulatory requirements that specifically address 
scoring of tablets, the Agency recognizes the need for consistent 
scoring between a generic product and its RLD.
    Consistent scoring ensures that the patient is able to adjust the 
dose, by splitting the tablet, in the same manner as the RLD. This 
enables the patient to switch between products made by different 
manufacturers without encountering problems related to the dose. In 
addition, consistent scoring ensures that neither the generic product 
nor the RLD has an advantage in the marketplace because one is scored 
and one is not.
    The Center for Drug Evaluation and Research's Drug Safety Oversight 
Board considered the practice of tablet splitting at its October 2009 
and November 2010 meetings. During those meetings, they discussed how 
insurance companies and doctors are increasingly recommending that 
patients split tablets, either to adjust the patients' dose or as a 
cost-saving measure. Because of this, the Agency conducted internal 
research on tablet splitting and concluded that in some cases, there 
are possible safety issues, especially when tablets are not scored or 
evaluated for splitting. The Agency's concerns with splitting a tablet 
included variations in the tablet content, weight, disintegration, or 
dissolution, which can affect how much drug is present in a split 
tablet and available for absorption. In addition, there may be 
stability issues with splitting tablets.
    Tablet splitting also is addressed in pharmacopeial standards. The 
European Pharmacopeia currently applies accuracy of subdivision 
standards for scored tablets--and has at various times also included 
standards for content uniformity, weight variation, and loss of mass--
while the United States Pharmacopeia published a Stimuli article in 
2009 proposing criteria for loss of mass and accuracy of subdivision 
for split tablets.
    As an outgrowth of these discussions, FDA is providing 
recommendations for application content regarding the scientific basis 
for functional scoring on solid oral dosage form products to ensure the 
quality of both NDA and ANDA scored tablet products. To accomplish 
this, the Agency has developed consistent and meaningful criteria by 
which scored tablets can be evaluated and labeled by: (1) Providing a 
harmonized approach to chemistry, manufacturing, and controls reviews 
of scored tablets; (2) ensuring consistency in nomenclature (e.g., 
score versus bisect) and labeling; and (3) providing information 
through product labeling or other means to health care providers.
    This guidance is being issued consistent with FDA's good guidance 
practices regulation (21 CFR 10.115). The guidance represents the 
Agency's current thinking on tablet scoring: Nomenclature, labeling, 
and data for evaluation. It does not create or confer any rights for or 
on any person and does not operate to bind FDA or the public. An 
alternative approach may be used if such approach satisfies the 
requirements of the applicable statutes and regulations.
