# SUPPLEMENTARY INFORMATION:

## I. Background

FDA is announcing the availability of a guidance for industry entitled “Quality Attribute Considerations for Chewable Tablets.” Chewable tablets are an immediate release oral dosage form intended to be chewed and then swallowed by the patient, rather than swallowed whole. This guidance describes the critical quality attributes that should be considered when developing chewable tablet dosage forms and recommends that the selected acceptance criteria be appropriate and meaningful indicators of product performance throughout the shelf life of the product.

This guidance finalizes the draft guidance issued June 16, 2016, (81 FR 39673) which described the Chewing Difficulty Index (CDI), a new quality attribute concept that was developed internally and findings were published in a peer reviewed journal. We received comments primarily seeking clarity how this new parameter would be assessed during regulatory review. The Agency provided additional clarifications in this guidance whereby sponsors and/or applicants would accrue CDI data during drug product development and submit it in their applications. We intend to evaluate the data to inform future guidance on this topic, as needed.

                    This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the current thinking of FDA on “Quality Attribute                           ( print page 42307)                        Considerations for Chewable Tablets.” It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations. This guidance is not subject to Executive Order 12866.                

## II. Paperwork Reduction Act of 1995

This guidance refers to previously approved collections of information that are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The collection of information in investigational new drug applications is approved by OMB under control number 0910-0014; the collection of information (including prescription drug labeling) in new drug applications and abbreviated new drug applications, as well as supplements to these applications, is approved by OMB under control number 0910-0001; the collection of biologics license applications is approved by OMB under control number 0910-0338; and the format and content of prescription drug labeling is approved by OMB under control number 0910-0572.

## III. Electronic Access

                    Persons with access to the internet may obtain the guidance at either                     *https://www.fda.gov/​Drugs/​GuidanceComplianceRegulatoryInformation/​Guidances/​default.htm*                     or                     *https://www.regulations.gov*.
