while the tablets containing CMS showed obvious superior hardness to that of the other starches. The disintegration of tablets containing native yam starch was faster than that of tablets with corn, rice, and tapioca starches. With increasing native starch concentrations, the disintegration of the tablets was found to be faster. Mark M.

The solubility of tablets in liquids is subject to the effectiveness of the dissolution rate. Some tablets readily dissolve without any full or partial disintegration. A tablet should also be permeable through the intestine walls to be absorbed into the blood circulation. Such factors prompt dissolution tests to be conducted regularly in drug ...

Pinkfong Baby Shark drinks vending machine toys play! Let's get milk and candy~! In pharmaceutical industry, disintegration is an essential test performed for testing disintegration capability of tablets and capsules etc as per pharmacopoeial standards like USP, BP and IP etc. Each pharmacopoeia standard has its own set of standards and specifies disintegration tests of its own.
Disintegration is defined as that state in which no residue of the unit under test remains on the screen of the apparatus or, if a residue remains, it consists of fragments of disintegrated parts of tablets component parts such as insoluble coating of the tablets or of capsule shells, or of any melted fatty substance from the pessary or suppository or is a soft mass with no palpable core. An orally disintegrating tablet or orally dissolving tablet (ODT) is a drug dosage form available for a limited range of over-the-counter (OTC) and prescription medications. ODTs differ from traditional tablets in that they are designed to be dissolved on the tongue rather than swallowed whole. Intelligence: From Secrets to Policy, Edition 7 - Ebook written by Mark M.

Werner Lowenthal, Mechanism of action of starch as a tablet disintegrant V: Effect of starch grain deformation, Journal of Pharmaceutical Sciences, 61, 3, (455-459), (2006). Wiley Online Library Werner Lowenthal , Mechanism of action of tablet disintegrants: Correlation of tablet mean pore diameter and porosity , Journal of Pharmaceutical Sciences , 61 , 2 , (303-304) , (2006) . Lowenthal & Wood proved that the rupture of the surface of a tablet employing starch as disintegrant occurs where starch agglomerates were found. The conditions best suited for rapid tablet disintegration are sufficient number of starch agglomerates, low compressive pressure and the presence of water. The concentration of starch used is also very crucial part. If it is below the optimum . K. P ...
disintegration in the oral cavity without water. To achieve this goal, mannitol used as diluent and sodium saccharin as sweetening agent for the formulation of tablets. Attempts were made to enhance dissolution rate along with faster disintegration using superdisintegrants like Ac-Di-Sol,4 Sodium starch glycolate (SSG)5 and Kollidon CL6 in the The disintegration time for mouth dissolving tablets needs to be modified, as disintegration is required without water; thus the test should mimic disintegration in salivary content. For this purpose, a Petri dish (10 cm diameter) was filled with 9 ml of phosphate buffer solution, pH 6.8 (which correlated pH of saliva). The tablet was
The disintegration time of water-soluble tablets remains almost the same with or without the introduction of nonionic surfactants; however when surfactants are added the rate of water penetration generally increases especially for granules that are made with slightly soluble materials. Compound tablets were evaluated for hardness, friability, disintegration time and dissolution rate. Batches of tablets containing equivalent concentrations of AC-di-sol or maize starch were employed as standards. Results obtained indicate that Dioscorea dumetorium starch performed as much better as a
