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 


sradovich on DSK3GMQ082PROD with NOTICES
Federal Register / Vol. 83, No. 162 / Tuesday, August 21, 2018 / Notices 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.
