Coprocessed Excipient Products: Some flexibility is necessary for the design of tablet formulations. GENERAL PROPERTIES OF LACTOSE AS AN EXCIPIENT. A binder will help the tablet to remain intact after compression. Starch particles own a crystalline structure, and they are therefore insoluble in cold water. Maize, potato, rice and tapioca (cassava) starch were evaluated with respect to their properties on direct compression. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. Hence, tablets with higher crushing strengths can be manufactured. MCC forms very strong compacts under even low compression pressures. Table 5 gives list of some disintegrants commonly used in tablet formulations. Hence, tablet formation might be inhibited, unless the granule mass undergoes brittle fracture and creates new clean surfaces. This in contrast to the dramatic decrease in crushing strength of potato starch tablets containing the lubricant. Data sources include IBM Watson Micromedex (updated 2 Dec 2022), Cerner Multum (updated 7 Dec 2022), ASHP (updated 11 Nov 2022) and others. Here are some examples of binder excipients: The use of starch as a binder in tablet formulations has numerous benefits. Allen T. Particle size measurement.

This in contrast to the dramatic decrease in crushing strength of potato starch . J Pharm Sci 1968;57:12534. Moreover, intra granular starch in wet granulations is not as effective as dry starch [41-50]. Mannitol is nonhygroscopic and shows a low reactivity with drug substances. Therefore, the mechanical properties and the size distribution of lactose types must be known before making a selection out of many lactose grades. The compactibility of the starches was found to be strongly affected by the equilibrium moisture content of the starches, which is dependent on the relative humidity of the atmosphere under which the powders were stored. 2008;9(2):414-8. doi: 10.1208/s12249-008-9059-3. A Spray-Dried, Co-Processed Rice Starch as a Multifunctional Excipient for Direct Compression. Disintegrants may play an important role in the bioavailability of a drug in tablet dose forms. Binders can be added as dry powders to form a matrix that will include the drug, as in the case of dry granulation or direct compression. doi: 10.1208/pt050230. In addition, starch granules serve as disintegrant and glidant in many formulations, and their additional use as WG binder (in cooked form) limits the number of excipients. FOIA For instance, starch generally has to be present at levels greater than 5% to adversely affect compactibility, especially in direct compression. Magnesium stearate is still the most effective pharmaceutical lubricant. Because they promote cohesiveness, the binders, also called adhesives, help the other ingredients in a tablet to mix together. An official website of the United States government. Diluents are used to make of the desired bulk of the tablet when the dose of the drug is very less. Fillers/Diluents Used in Tablet Formulations are: Lactose (a-lactose monohydrate, anhydrite b-lactose, spray-dried lactose) Microcrystalline cellulose (Avicel PH 101, Avicel PH 200, Emcocel) 1.

Authors C E Bos 1 . Rice starch showed much better compactibility as compared to maize, potato and tapioca starch. Depending on the formulation design, some tablets containing higher percentages of MCC may disintegrate readily during disintegration tests without an additional disintegrant. Klein K. Grundlagen und Anwendungen einer durch Flammenhydrolyse gewonnen Kieselsure 4. Studies involving natural gums have shown that they can be a safer alternative to synthetic polymers such as PVP. For pharmaceutical purposes, starch does not flow well and cannot be compressed into strong compacts. Maize, potato, rice and tapioca (cassava) starch were evaluated with respect to their properties on direct compression. Disintegrants such as starch, sodium starch glycolate and microcrystalline cellulose may enable tablet disintegration by increasing the porosity and wettability of the compressed . This site needs JavaScript to work properly. Prototype tablet formulations with 50% drug loading (tablet weight: 400 mg) were prepared with API lot #2 and commonly used excipients that appeared to undergo relatively mild degradation during the excipient compatibility study, such as MCC, Lactose Monohydrate, Starch, HPBCD, and Magnesium Stearate with or without CSD as shown in Table 9.The tablets were compressed using a single station . Rice starch exhibited worst flowability, caused by its fine particle size as compared to the other starches. Epub 2020 Aug 24. volume9,pages 274282 (1987)Cite this article. Hydrophilic polymers, especially of low molecular weight, for instance, HPMC E6 (6 CP viscosity grade), can be dissolved in water to obtain a low-viscosity solution, and they bind well and contribute to plastic deformation during tableting. Pharmaceutisch Weekblad Glidants are materials that reduce interarticular friction, covering the particle surfaces with a thin layer, and as a result, helping in better granule flow. Depending on the physiological conditions and formulation, one needs a tablet of around 100 mg for ease of handling and administration, and therefore, fillers are used to increase bulk. Native starch in tablet formulations: Properties on compaction. One of the commercial products of PVP is KollidonTM (BASF), which has grades based on the molecular weight of the polymer: Kollidon K 25 (MW 28,000 34,000), K 30 (MW 44,00054,000), and K 90 (MW 1,000,0001,500,000) contain PVP of increasing molecular weights. shown).

Selecting each excipient depends on the physical and chemical properties of the drug, the drug dose, and the required final form and function of the tablet. Materials such as PVP and HPMC have largely replaced other binders such as gelatine, sucrose, simple syrup, or acacia. To evaluate the influence of Starch 1500 partially pregelatinized maize starch on the physical and chemical stability of formulations containing the moisture sensitive active, famotidine which has a well characterized degradation pathway due to hydrolysis. Pregelatinised starch is a multifunctional excipient that can be used as a tablet and capsule filler/diluent, wet granulation binder, and disintegrating agent. Among these are sodium carboxymethyl starch (ExplotabTM, Mendell, U.S.A.), cross-linked sodium carboxymethyl cellulose (PharmacelTM XL, DMV, Netherlands), and cross-linked PVP (KollidonTM XL, BASF). The use of native starch as excipient in extended-release tablets is limited due to its low compactibility and enzymatic degradability, leading to the formation of weakly structured tablets. All starches showed adequate capacity for water uptake to act as a disintegrant. When disintegrants come into contact with water, they usually swell, as their cross-linked molecular structure, such as in amylose in starch or cross-linked PVP, imbibes water and swells, providing the force to disperse the tablet. Its secondary function is as a disintegrant. Using three different drying techniques, fluidized-bed methods, roller drying, and spray drying, a-lactose monohydrate, anhydrous b-lactose, and spray-dried lactose are obtained, respectively. Dave RH. sharing sensitive information, make sure youre on a federal Usually, a lactose monohydrate is the first material to be considered. Pharmaceutisch Weekblad Scientific Edition 9, 274282 (1987). In tablet formulation, excipients are usually combined at various quantities with the active drug substance(s) to produce tablets that are of standard quality. Moreover, its binding capacity proved to be almost insensitive to mixing with magnesium stearate. Its bulk density is an important characteristic that is related to the functional properties of the excipient. Gums and mucilage, which are abundant in nature, are used as natural excipients in the pharmaceutical industry. Lubricants are a mechanical necessity, without which modern tablet manufacturing would be impossible. AAPS PharmSciTech. For instance, anhydrous b-lactose shows a steep compression forcetablet crushing strength relation. Prolonged mixing with a surface[1]covering lubricant such as magnesium stearate negatively affects the binding capacity of a granule mass. Accessed 08/19/2011, David A Bender. Rice starch showed much better compactibility as compared to maize, potato and tapioca starch. For example, starch is a multi-functional excipient for tablets. Starch conversion technology. AAPS PharmSciTech. Therefore, good compressibility can be matched with good flow only by selecting the right grade or making a wet granulation to a certain size and shape. 1982;19(6):421-36 Physicochemical and binder properties of starch obtained from Cyperus esculentus. Liquid paraffin and hydrogenated vegetable oil are also among the lubricants, but their effectiveness is lower than that of magnesium stearate and stearic acid.

Colloidal silicon dioxide, talc, and starch can be used as glidants; colloidal silicon dioxide is effective as low as 0.5% as a glidant. Recent trend in pharmaceutical industry is . Besides, the function of some excipients not necessary in some formulation. Lubricants are added to pharmaceutical granules just before the tableting stage. Historically, gelatin has been used as a binder in tablet formulation. Its usual concentration range is between 0.1% and 2%, and its effectiveness shows a biphasic profile, a region of a fast reduction in friction up to 1 %, and a slower friction-reducing effect after 1%. Before Results revealed that partly pregelatinized starch is a relatively suitable binder for orally disintegrating tablets as it also serves as a disintegrant. 2021 Jan;79(1):28-35. doi: 10.1016/j.pharma.2020.08.004. Bookshelf [ 1] Starches also absorb water rapidly, allowing tablets to disintegrate appropriately. Natural polymers and gums such as pregelatinized starch, starch, acacia . This water-soluble disaccharide is obtained from whey by crystallization and drying after cheese production. It may serve as diluent, binder, and disintegrating agent. The three different lactose grades differ considerably in their mechanical properties about tableting. Starch paste has been a traditional binder, at concentrations between 5% and 10%. This material is provided for educational purposes only and is not intended for medical advice, diagnosis or treatment. -, J Pharm Sci. The compactibility of the starches was found to be strongly affected by the equilibrium moisture content of the starches, which is dependent on the relative humidity of the atmosphere under which the powders were stored. Bolhuis GK, Lerk CF, Zijlstra HT, De Boer AH. Moreover, its binding capacity proved to be almost insensitive to mixing with magnesium stearate. Disintegrants serve the purpose of facilitating the disintegration of tablets into their components either after administration in the GI tract or just before administration, such as in the case of the fast-disintegrating tablets. The main mechanism of compaction of dicalcium phosphate is a brittle fracture, creating new surfaces, which therefore shows much less lubricant sensitivity: This can be an advantage over plastically deforming materials such as MCC or some starches. For instance, starch generally has to be present at levels greater than 5% to adversely affect compactibility, especially in direct compression. 3.1.1 Gelatinization. J Pharm Sci 1981;70:132830.

Lactose is a water-soluble diluent, 216 mg dissolving in 1-mL water. For effervescent tablets, water-soluble lubricants are required since insoluble alkaline lubricants would accumulate on the surface of the final solution or form a cloudy solution with an alkaline taste, all of which is undesirable. Characteristics of disintegrant This property is measured by the Carrs index or the Hausner ratio. Traditionally, starch has been the disintegrant of choice in tablet formulations, and it is still widely used. Binders in tablet technology serve the purpose of binding small drug or excipient particles together to impart cohesiveness, and to form a granulate of a designed size range, usually larger than the initial material that flows freely and is also compressible, and eventually to be compressed into tablets or to be filled into capsules. The result is mechanically stronger tablets. Crystalline form of substances can be directly compressed into tablet, but majority of drugs will have to be converted to granules before compression.

During ingestion, starch granules swell due to the fluid environment in the stomach. the formulation and the method of preparation. . The most common use of starch as a pharmaceutical excipient is as binder and disintegrant in the formulation of tablets and other solid dosage forms. Act Pharm Suec 1982;19:42136. PMC official website and that any information you provide is encrypted 1968 Jul;57(7):1253-5 Binders are one of the critical excipients for a successful wet granulation formulation. Starch paste has historically been one of the most common granulating agents. Moreover, it can be combined with at least one other excipient to achieve the desired properties. Spray-dried lactose flows well because of its spherical granule shape. Laboratory for Pharmaceutical Technology and Dispensing, State University of Groningen, Ant. MNA tablets for all formulations showed a good hardness profile and conformed to specifications for tablet hardness of between 5 to 8 kg. Microcrystalline cellulose, on the other hand, has very low agglomeration potential, and can be used to make tablets with minimal agglomeration force, Browse around this site. Magnesium stearate reduces not only the lower punch ejection force by about 70% but also tablet tensile strength. One of the most significant advantages of PVP is its low viscosity (510 mPa.sec) even up to concentrations as high as 20% (w/v). On the other hand, a-lactose monohydrate and even spray-dried lactose are inferior grades in this respect. 2. All of the above sucrose-based . Katalog Pharmazeutischer Hilfstoffe.
