Letter to Dockets -- medications
CSA supports eliminating ALL ingredients derived from gluten sources, from ALL forms of human medications.
Gluten, in the celiac world, is the inclusive term used to describe the amino acid sequences that evoke the immune mediated T and B cell responses in those with celiac disease. These amino acid sequences are ubiquitous in the grasses of the genus triticum, hordeum, secale, and to a lesser amount in avena plants.[i] [ii] [iii] Oats should also be eliminated from medications to fully protect all people with celiac disease because the toxicity depends upon the variety of the oats.[iv] The toxic amount of gluten for any one person is truly not known.
The only accepted treatment for celiac disease is lifelong adherence to a gluten-free lifestyle defined as strict elimination of foods, beverages, medications, supplements and toiletries containing gluten from wheat, barley or rye and to a lesser extent oats.. The FDA Hazard Report reviewed the limited non-confirming data and noted on page 45, “the tolerable daily intake level for gluten in individuals with celiac disease was determined in a safety assessment to be 0.4 mg gluten/day for adverse morphological effects and 0.015 mg gluten/day for adverse clinical effects.” [v] The toxic amount of gluten for any one person is truly not known.
The use of the term gluten-free in drugs and supplements is not standardized. The “celiac safe” communication system with drug companies related to active, inactive ingredients and processing agents has deteriorated. The ability for company representatives to confirm the presence or lack of presence of derivatives from wheat, barley, rye or oats has worsened since 2008.
On December 21, 2011, FDA’s Center for Drug Research and Evaluation (CDER) issued a Federal Register notice (76 FR 79196) to request information and public comments on a series of questions related to the presence of gluten in drug products (i.e., prescription, nonprescription, biologic, and homeopathic drug products). CDER is considering the public comments it received in response to this notice as it evaluates options to help individuals with celiac disease limit gluten exposure from consumption of drug products. CSA supports the Citizen Petition submitted by Michael Weber, June 2008 in docket references.
There is no down side to eliminating gluten from human medications. Elimination of the ingredients with the toxic amino acid sequences that evoke the systemic immune mediated responses is the only method to assure the wellbeing of those diagnosed with celiac disease.
For the health and well being of the increasingly diagnosed celiac population and others with gluten induced health conditions, the Celiac Support Association strongly endorses the elimination of ingredients derived from wheat, barley, rye and common oats in all human medications.
