  • Calcium Stearate Processing
    National Organic Standards Board Technical Advisory Panel (TAP) Review Compiled by University of California Sustainable Agriculture Research and Education Program (UC SAREP) for the USDA National Organic Program Calcium Stearate Processing Executive Summary1 A petition is under consideration with respect to NOP regulations subpart G §205.605, governing the use of substances in processed products: Petitioned: Inclusion of calcium stearate on National List of nonagricultural substances allowed in or on processed products labeled as “organic” or “made with organic (specified ingredients or food group(s)).” Calcium stearate is a compound of calcium with a mixture of solid organic acids obtained from edible sources. It is generally used as a solid-phase lubricant that reduces friction between particles of the substance to which it is added. The Petitioner’s intended use is “as a flow agent (anti-dusting agent)” to be used in dry flour based ingredients sold to bakeries (NOSB Petition). The NOP has no prior listing or ruling on the substance. All three reviewers agreed that the substance should be considered synthetic. The reviewers were divided over the use of calcium stearate in food labeled as “organic.” Two of the reviewers felt it should not be allowed in these foods, while one reviewer felt it should be accepted. One reviewer who voted to restrict its use indicated that more information was needed on the nature of the substance and its potential applications, and the other reviewer felt that inclusion of a “synthetic” substance in organics runs contrary to consumer’s expectations regarding organic products. All three reviewers agreed that the substance should be allowed in products labeled as “made with organic…” ingredients.

Received: 18 December 2013; in revised form: 21 January 2014 / Accepted: 24 January 2014 / Published: 25 February 2014 Abstract: Lubrication plays a key role in successful manufacturing of pharmaceutical solid dosage forms; lubricants are essential ingredients in robust formulations to achieve this. Although many failures in pharmaceutical manufacturing operations are caused by issues related to lubrication, in general, lubricants do not gain adequate attention in the development of pharmaceutical formulations. In this paper, the fundamental background on lubrication is introduced, in which the relationships between lubrication and friction/adhesion forces are discussed. Then, the application of lubrication in the development of pharmaceutical products and manufacturing processes is discussed with an emphasis on magnesium stearate. In particular, the effect of its hydration state (anhydrate, monohydrate, dihydrate, and trihydrate) and its powder characteristics on lubrication efficiency, as well as product and process performance is summarized. In addition, the impact of lubrication on the dynamics of compaction/compression processes and on the mechanical properties of compacts/tablets is presented. Furthermore, the online monitoring of magnesium stearate in a blending process is briefly mentioned. Finally, the chemical compatibility of active pharmaceutical ingredient (API) with magnesium stearate and its reactive impurities is reviewed with examples from the literature illustrating the various reaction mechanisms involved.

In the treatment of many diseases, it is crucial to control the dosing of a drug for a long time and thus maintain its optimal concentration in the tissue. Heart diseases are particularly important in this aspect. One such disease is an obstructive arterial disease affecting millions of people around the world. In recent years, stents and balloon catheters have reached a significant position in the treatment of this condition. Balloon catheters are also successfully used to manage tear ducts, paranasal sinuses, or salivary glands disorders. Modern technology is continually striving to improve the results of previous generations of stents and balloon catheters by refining their design, structure, and constituent materials. These advances result in the development of both successive models of drug-eluting stents (DES) and drug-eluting balloons (DEB). This paper presents milestones in the development of DES and DEB, which are a significant option in the treatment of coronary artery diseases. This report reviews the works related to achievements in construction designs and materials, as well as preparation technologies, of DES and DEB.

For the dissolution studies, water was chosen as the Apart from their desired effect of reducing the ejection force and dissolution medium to avoid any influences of salts or pH on the punch adhesion, lubricants also have a considerable influence on dissolution properties of the resulting tablets. the tablet hardness, disintegration, and dissolution times due to their inherent hydrophobicity. This study aimed to investigate the Materials and Methods influence of the lubricant molecular structure on the aforemen- tioned characteristics. For this purpose, active pharmaceutical All powder blends were prepared using a free fall blender. First, ingredients (APIs) with high and low water solubility have been the API was blended withPROSOLV® SMCC HD 90 for 15 minutes. evaluated in combination with 4 different, stearyl-based lubri- Afterwards, the sieved lubricant was added and the mixture was cants.

For the dissolution testing, the medium water was tempered to Introduction 37 °C.
