Micromeritic properties of starch and aspirin

micromeritic properties of starch and aspirin This randomization should have resulted in four groups of equal size for assignments to aspirin plus placebo, aspirin plus starch, starch plus placebo, and placebo plus placebo.

The first one had three disintegrants (corn starch, cation-exchange resin, and waxy maise starch) at four different concentrations (0, 5, 10, and 15%), and three levels of compression pressure (1000, 3000, and 6000 psig) with aspirin. Aspirin, acetylsalicylic acid or simply asa, is used for different medical conditions depending on the strength of the dose and how it is taken. Starch 1500 is a unique pharmaceutical excipient combining several properties in a single product : binder, disintegrant, filler and flow-aid while having lubricant properties.

Best answer: i didn't quite understand your question, but i guess you're asking about it's role and advantages starch in the drug manufacturing could be used as diluents, disintegrants or binders aspirin is a highly hygroscopic drug although starch contains (12-14%) moisture, they have the ability to stabilize hygroscopic drugs like aspirin. Aspirin (2nd edition) compiled by david lewis edited by colin osborne and maria pack designed by imogen bertin and sara roberts first published by the royal society of chemistry in 1998 found to have good medicinal properties, low membrane irritation and a reasonable taste this followed the publication of news about the. The test used in this part was iodine test, which is a test for the presence of starch (since iodine can form a black complex with starch)after dissolving synthesized aspirin in 2ml water and 1ml iodine solution, a mixture of red-orange liquid and white precipitates was obtained while when commercially available aspirin was dissolved in 2ml.

Some physical properties are thin ( when gridded) and white that is all i can think of. Micromeritic properties of the blended granules were evaluated using metrics such as flow rate, angle of repose, bulk and tapped densities, compressibility (carr’s) index and hausner ratio following previously reported method 4 however, 20g of granules was used in the evaluation and repeated in triplicate while dimensions of funnel used were. Read tableting properties of a directly compressible starch, journal of pharmaceutical science on deepdyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips.

Total porosity and pore-size distribution of aspirin tablets prepared from aspirin, starch usp, and precipitated colloidal silicon dioxide were determined using mercury porosimetry the model represented a hydrolyzable drug substance in combination with simple excipients. The properties of starch 1500® makes it an excellent diluent to enhance stability of moisture sensitive drugs starch 1500 ® is inhibiting water activity within the formulation and retarding interaction with the. Micromeritic properties of pharmaceutical powders are among the primary parameters given serious consideration prior to their formulation into various solid drug delivery systems to study these. The common crystal form of ibuprofen was changed to optimize processing and manufacturing properties six modified crystal forms were prepared and assessed for dissolution, morphology, particle size, density, thermal characteristics, powder x-ray diffractometry, flow properties, and tabletability. The spray-dried powder, mixed with neocel or flo-starch, or the mixture of neocel and flo-starch (weight ratio, 1:1) was directly compressed into a tablet the micromeritic properties of the spray-dried powder and the mixed powder for tableting were investigated.

Direct correlation between starch physicochemical properties and digestibility of the low- amylose starches was observed chinese and bitter yam starches with the lowest amylose content were found to have the highest digestibility in vitro (2127 . Aspirin is known as pain reliever or a drug that relieves pain and inflammation, lowers fever, and reduces blood clottingthe first sign of aspirin was by a 5th century greek physician who discovered the medical properties of the willow tree's bark the medicinal part of the plant is the inner bark of a tree the active extract of the bark is. Using waxy corn starch as raw material, enzymatically modified starch was prepared by debranching enzyme such as pullulanase and physical retro gradation treatment the micromeritic characteristics of starches were compared aspirin tablets were prepared with different proportion prescription of the starch and the feasibility of application of linear crystal starch instead of micro crystal. The correlations between micromeritic properties of raw material powders and the formability of their pellets were analyzed by cluster analysis, principal component analysis and partial least squares regression analysis.

The micromeritic properties of the granules were determined using the direct and indirect methods the necessary official and non official tests were performed on the tablets to include uniformity of tablets weight, content of active ingredient, disintegration test, hardness, friability tests and in vitro drug release. Aspirin is the most widely used over-the-counter drug in the world the average tablet contains about 325 milligrams of the active ingredient acetylsalicylic acid with an inert binding material such as starch aspirin is used to relieve pain, reduce inflammation, and lower fever aspirin. Starch test test tube observation commercial (+) blue-black aspirin colored solution synthesized (–) no reaction aspirin control (–) no reaction aspirin tablets are acetylsalicylic acid pressed together with a small amount of inert binding material, such as starch, methylcellulose and microcrystalline cellulose. Preparation and characterization of rofecoxib microspheres using cross-linked starch as novel drug delivery system thombre n a1, chaudhari mr2, kadam ss 2 1 department of pharmaceutics, met’s institute of pharmacy, bhujbal knowledge city, micromeritic properties: 9 1 angle of repose.

The results of granular micromeritic properties like bulk density, angle of repose, carr’s index and hausner’s ratio showed that all the formulations possessed good flow properties, uniformity and compressibility. The physical properties of the tablets were evaluated by suitable techniques microcrystalline maize starch co-processed excipient, its physical admixture, metronidazole, ascorbic acid as well as mixture of the co- the micromeritic properties of the. Compared to starch the various micromeritic characteristics and flow properties of the granules obtained by wet granulation for each batch and reference batch did not show any significant variation in their values the values of physical properties of all batches are shown in table 2 having average of triplicate readings, with standard.

To produce hard aspirin tablets, corn starch and water are added to the active ingredient (acetylsalicylic acid) to serve as both a binding agent and filler, along with a lubricant binding agents assist in holding the tablets together fillers (diluents) give the tablets increased bulk to produce tablets of adequate size. The micromeritic properties of the prepared agglomerates were evaluated for bulk density, tapped density, carr’s index, hausner’s ratio, angle of repose along with the release behavior of agglomerates. Organoleptic properties and micromeritic studies the results showed that the gelatinized starch possess optimum organoleptic as well as micromeritic properties the gelatinized starch was modified and four deferent properties of sago starch were observed and found to be sago starch were evaluated and are summarized in table 1.
