Draft Guidance for Industry on Limiting the Use of Certain 
Phthalates as Excipients in Center for Drug Evaluation and Research-
Regulated Products; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

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

SUMMARY: The Food and Drug Administration (FDA) is announcing the 
availability of a draft guidance for industry entitled ``Limiting the 
Use of Certain Phthalates as Excipients in CDER-Regulated Products.'' 
This draft guidance provides the pharmaceutical industry with the 
Center for Drug Evaluation and Research's (CDER's) current thinking on 
the potential human health risks associated with exposure to dibutyl 
phthalate (DBP) and di(2-ethylhexyl) phthalate (DEHP). In particular, 
the draft guidance recommends that the pharmaceutical industry avoid 
the use of these two specific phthalates as excipients in CDER-
regulated drug and biologic products, including prescription and 
nonprescription products.

DATES: Although you can comment on any guidance at any time (see 21 CFR 
10.115(g)(5)), to ensure that the Agency considers your comment on this 
draft guidance before it begins work on the final version of the 
guidance, submit either electronic or written comments on the draft 
guidance by May 31, 2012.

ADDRESSES: Submit written requests for single copies of the draft 
guidance to the Division of Drug Information, Center for Drug 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access to the draft guidance document.
    Submit electronic comments on the draft guidance to http://www.regulations.gov.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.

FOR FURTHER INFORMATION CONTACT: Laurie Muldowney, Center for Drug 
Evaluation and Research (HFD-003), Food and Drug Administration, Bldg. 
51, Rm. 4154, 10903 New Hampshire Ave., Silver Spring, MD 20993-0002,

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Limiting the Use of Certain Phthalates as Excipients in 
CDER-Regulated Products.'' This draft guidance provides the 
pharmaceutical industry with CDER's current thinking on the potential 
human health risks associated with exposure to DBP and DEHP. In 
particular, the draft guidance recommends that the pharmaceutical 
industry avoid the use of these two specific phthalates as excipients 
in CDER-regulated drug and biologic products, including prescription 
and nonprescription products. The recommendations in this guidance do 
not address the use of DBP or DEHP in other types of FDA-regulated 
products or exposure to DBP or DEHP due to the presence of any of these 
compounds as an impurity--including as a result of leaching from 
packaging materials.
    Phthalate esters (phthalates) are synthetic chemicals with a broad 
spectrum of uses. Phthalates are found in certain pharmaceutical 
formulations, primarily as a plasticizer in enteric-coatings of solid 
oral drug products to maintain flexibility, but they also may be used 
for different functions in other dosage forms. Phthalates also are 
found in other products for uses such as softeners of plastics, 
solvents in perfumes, and additives to nail polish, as well as in 
lubricants and insect repellents.
    Phthalates have been studied extensively in animals, and DBP and 
DEHP have been shown to be developmental and reproductive toxicants in 
laboratory animals. While the data in humans are less clear, 
epidemiological studies suggest that certain phthalates may affect 
reproductive and developmental outcomes. Other studies have confirmed 
the presence of DBP and DEHP in amniotic fluid, breast milk, urine, and 
serum.
    Data from the National Health and Nutrition Examination Survey 
(NHANES) indicate widespread exposure of the general population to 
phthalates. Humans are exposed to phthalates by multiple routes, 
including inhalation, ingestion, and to a lesser degree absorption 
through the skin. Several observational human studies have reported an 
association between exposure to certain phthalates and adverse 
developmental and reproductive effects. The ubiquitous presence of 
phthalates in the environment and the potential consequences of human 
exposure to phthalates have raised concerns, particularly in vulnerable 
populations such as pregnant women and infants.
    Although the currently available human data are limited, the Agency 
has determined that there is evidence that exposure to DBP and DEHP 
from pharmaceuticals presents a potential risk of developmental and 
reproductive toxicity. While it is recognized that drug products may 
carry inherent risks, DBP and DEHP are used as excipients, and safer 
alternatives are available. Therefore, the Agency recommends avoiding 
the use of DBP and DEHP as excipients in CDER-regulated drug and 
biologic products.
    These recommendations apply to CDER-regulated drug and biologic 
products that are under development (i.e., investigational new drugs), 
nonapplication products (e.g., over the counter monograph products), 
and both marketed approved products and those currently under review 
for marketing consideration (i.e., new drug applications, abbreviated 
new drug applications, and biologics license applications).
    There are alternatives to DBP and DEHP for use as excipients in 
CDER-regulated products. Manufacturers with products that contain DBP 
or DEHP should consider alternative excipients and determine if the 
alternative excipient they plan to use has been used in similar CDER-
approved products and at what level.
    The Inactive Ingredients Database provides information on 
excipients present in FDA-approved drug products, and this information 
can be helpful in developing drug products. As manufacturers 
reformulate their products, the listings for DBP and DEHP will be 
removed from the Inactive Ingredients Database.
    This draft guidance is being issued consistent with FDA's good 
guidance practices regulation (21 CFR 10.115). The draft guidance, when 
finalized, will represent the Agency's current thinking on limiting the 
use of certain phthalates as excipients in CDER-regulated products. 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.
