Figure 2971 tablet friability apparatus for tablets with a unit mass equal to or less than 650 mg take a sample of whole tablets corresponding as near as possible to 65 g for tablets with a unit mass of more than 650 mg take a sample of 10 whole tablets the tablets are carefully dedusted prior to testing accurately weigh the
Although medications commercially available in oral solid dosage forms are suitable for most patients there are populations and circumstances that require splitting tablets crushing tablets or opening capsules for example pediatric and geriatric populations may require dosage strengths that are not commercially available
Tablets are solid drug delivery system prepared by compressing a single dose of one or more active drug substances with some additives pharmaceutical excipients they may be circular oblong oval triangular or cylindrical in shape and flat round concave
The term crushing strength is also frequently used to describe the resistance of tablets to the application of a compressive load crushing strength disintegration time and weight tablets compressed from 16 different mixtures of avicel grades ph101 ph102 and ph200 were studied using a mixture design
Crushing strength crushing strength of 40 150n is recommended satisfactory for tablets 26 the values of crushing strength varied significantly p 005 among the brands brand a failed the test with a value of 258n while other brands had values within the acceptable limits table 2 poor crushing strength as seen in brand a may result
Regular catalyst shapes such as tablets and spheres extrudates granular materials and other irregular shapes are specically excluded 12 this test method determines the average crush strength in the range from 0 to 50 lbf 0 to 220 n2 13 the values stated in inchpound units are to
Crush tablets finely and mix with water the lower strength tablets will disperse in 1 to 5 mins without crushing the higher strength tablets should be crushed before mixing with water give immediately flush well after each dose2 25mg5ml oral solution included in part viiib of
The crushing strength of tablets is usually checked using monsanto or stokes hardness tester strongcobb hardness tester and the pfizer crushing strength tester all are manually used so strain rate depends on the operator
A straightforward approach for larger entities is the tablet hardness tester that measures the crushing strength in axial or radial direction of a single pellet and tablet this approach does not work for smaller entities and therefore we have developed the robotic compression tester that is able to measure the individual crushing strength of
So what does it take to crush or break a tablet product method in this test an ftc tmspro texture analyzer was fitted with a 500 n intelligent loadcell and 15 inch 38 mm cylinder probe a short program advanced the probe to touch the tablet sample before advancing a further 1 mm as sufficient to always break the sample
Tablets with microcrystalline cellulose mc as the diluent had the highest tablet crushing strength at any given compression pressure heckel plots of all the microspherediluent blends were nonlinear indicating that the consolidation may result from crushing and rearrangement of the individual particles in addition to plastic deformation
How the tablet disintegrates into its primary particle and not the release of active substance mechanical properties hardness often measured as the force needed to crush the tablet often called the crushing strength although in reality it is linked to the failure force friability describes extent to which the powder tends to be removed
