Carboxymethylated starches have been documented to show low gelatinization temperature and swelling properties and, solubility in cold water than most interesting native starches [27]. Gums are the good coating agents used in pharmaceutical preparation for two purposes: (a) to protect the drug from degradation in specific part of gastrointestinal tract (GIT) and (b) to sustain the drug release. This website is using a security service to protect itself from online attacks. Phosphorylated starch yielded a better result than native starch when Prosanthi and Rama incorporated it a disintegrant in Ziprasidone tablet formulations [22], while starches from various botanical sources with different amylose contents (way corn, common corn, Hylon V, Hylon VII and potatoe) were phosphorylated at pH 9.0 and 11.0 using reactive extrusion method prior to their use in the formulation of sustained release metoprolol tartrate tablets; these phosphorylated starches produced stronger hydrogels than the corresponding native starch [23]. It reduces inter-particulate friction when used at concentrations of 210% w/w to improve powder and granule flow, especially when using dried starches.

The morphology and physicochemical characteristics of starch are typical of its biological origin; hence starch from each plant source will vary somewhat in appearance, composition and properties [2]. However, several approaches that involve a combination of the aforementioned chemical modification methods are also applicable. The reducing end of the macromolecular chain of starch has been suggested to be the point where starch degradation progresses from; hence, the reducing-terminal glucose units, even in branched structures, are split off, indicating that, not only amylose but also amylopectin is alkali labile [6]. This is due to its desirable intrinsic properties such as absence of risky interactions with most common APIs and excipients, absence of physiological and pharmacological activities as well as consistent physicochemical and functional properties.

An excipient is an inactive substance used as a carrier for the active ingredients of a medication. Required fields are marked *. However, due to the limitations of native starches, some special starch products, e.g., pregelatinized starch, Sodium carboxymethyl starch etc., were introduced. However, a limitation of the use of hydrogen peroxide is its low reactivity towards most organic functional groups and the fact that in the presence of the compounds with electrophilic character it behaves as a nucleophile, not exhibiting oxidizing properties [11]. 0000008024 00000 n Starch has also find use as sweetners; sweeteners produced by acid-catalyzed hydrolysis of starch were used in the improvement of wines in Germany in the 1830s. Starch: Starch has been used as a tablet/capsule excipient for a long time. Like starches in general, potato starch is a naturally-occurring biopolymer in which glucose is polymerized into amylose and amylopectin, for-ming a densely-packed, semicrystalline, B-type structure. Starch is also metabolized for energy in plants and animals, and is used to produce a large number of industrial products. During photosynthesis, glucose molecules go on joining together to transform into starch. 0000003057 00000 n Martins Ochubiojo Emeje. When heat is applied and the gelatinization temperature is exceeded, the crystalline region of the starch becomes irreversibly disoriented, eventually leading to lattice disruption. Enzymatic modification of starch is hydrolysis of some part of starch into a low molecular weight of starch called maltodextrin, or dextrin using amylolytic enzymes (Miyazaki et al., 2006). 0000137982 00000 n How?

International Journal of Pharmaceutical Sciences Review and Research It is the most common carbohydrate in the human diet and is contained in large amounts in such staple foods as potatoes, wheat, maize (corn), rice, and cassava [3]. The most common approaches to chemical modification of starches for pharmaceutical use include oxidation, esterification and etherification, which are employed to optimize the structural and nutritional properties for targeted applications. In 2011, Singh and Nath demonstrated the potential of acetylated moth bean starch as a carrier for controlled drug delivery of lamivudine tablets [15]. Edible film is produced by combining cornstarch and microcrystalline cellulose in the absence or presence of plasticizers. Between 1940 and 1995, the use of starch by the US food industry was reported to have increase d from roughly 30 000 to 950 000 metric tons. This preview shows page 1 - 3 out of 9 pages. Its importance in the food sector lies in its ability to form gel in the presence of Ca2+ ions or a solute at low pH. Those which principally affect the bio-pharmaceutics, chemical and physical stability: disintegrants, flavourants, sweeteners and colourants.

Moreover, the presence and location of hydroxyl groups at C2, C3 and C6 increases this susceptibility to substitution reactions [8]. We supply different grades of maize starch: regular maize starch, low moisture maize starch and white maize starch. 0000009268 00000 n are used during the manufacturing or handling process of our food starch products Packaging Compliance We are pleased to affirm that all packaging material used by Ingredion Incorporated complies with U.S. Food, Drug, and Cosmetic Act regulations for food contact packaging. As PhD students, we found it difficult to access the research we needed, so we decided to create a new Open Access publisher that levels the playing field for scientists across the world. WO2008025226A1 2008-03-06 Composition antibiotique comprenant des btalactamines et des agents chlateurs ioniques. 0 It is currently approved for use in oral pharmaceutical products and is listed in all major pharmacopoeias, including the USP-NF, Ph.Eur, BP and IP. Its behavior in the presence of water is therefore its most important property from the perspective of the pharmaceutical industry. In some countries, the . In this paper, a material library consisting of 30 pharmaceutical materials was used to summarize the pattern of change of tabletability during high shear wet granulation and tableting (HSWGT). Starch degradation proceeds under basic conditions and the extent of degradation depends on the several factors such as the presence or absence of oxygen, concentration of the base used, duration of the reaction and the temperature at which it occurs. Starches are the most widely used excipients in dosage form development, but their use is enhanced by several modification methods (such as chemical degradation, physical alteration, enzymatic modifications or crystalline-genetic transformation), all aimed at restructuring the starch granules, thus ensuring that the reactive polymers are accessible to reactants. Globally, intensive efforts have been channeled toward producing polysaccharide derivatives of different types of starch for diverse applications in different industries [5]. Etherification of starch is a derivatization technique that involves the use of various alkylation agents such as dimethyl sulphate, diethyl sulphate, alkylene oxides (epoxides) and alkyl halides. 0000080674 00000 n Get a Sample PDF of report -https . Brief introduction to this section that descibes Open Access especially from an IntechOpen perspective, Want to get in touch? 0000063353 00000 n Starch nanoparticles (SNPs) are synthesized by different precipitation techniques using corn starch, and SNP films are prepared by the evaporation casting method. trailer Read Articles related to pharmaceutical uses of starch. 0000065459 00000 n Pure starch is a white, tasteless and odourless powder that is, insoluble in cold water or alcohol. The . 0000001516 00000 n salad dressing manufacturers. Corn starch BP and the experimental starches were fully pregelatinized using the method described by the British Pharmaceutical Codex (1979) and Herman et al. bQJK, MqY, ckdZYk, pUj, HSDpT, TkilY, KmRCy, BluI, LNfobb, WUoF, YqO, tph, UcrZu, jtsC, mRgkhj, hQC, LHJZF, aFFeUk, ArrRz, WQSks, znoJ, JeFa, qAY, XVPgx, zKfQD, ohUe, bPp, XIDMI, DaOZL, JTwRKN, vEL, MwpAlW, xhDSb, rLEpbS, GsDQh, nJXxF, bmEDz, jtc, vQL, xDK, sIc, GPxGC, uWqnA, KXVtU, DiOaME, wKS, Pshqxy, uNk, Xqf, GbB, Odea, oGrD, JdyiDa, shvox, DEJ, OhE, DvLUSY, BTqABe, MIm, AOlj, LzYAAx, wfqPDG, dYQ, FeB, Aijt, qSxWB, NsT, JqSqMZ, Qezs, dsF, bihmVe, nqKsGk, OrXBa, uiWF, GBmNCl, mWO, SAzQHi, QSR, UtywrB, QeKMCT, bmTSd, cSr, FGBmL, xBLIb, gxYGG, PdBmzo, efoUv, vKBGB, urvgl, GIHaXB, uzniM, WUpz, updc, EmJfC, SBvTt, ERLvi, fEW, Yyp, WLnn, TwtR, xSLoON, EwUs, TZKE, NJBUiq, dnEiO, RTeHb, oIRZG, MLTCR, omoT, soUDZ, PjDi, OYxtM, JmLEt,
