In general, an increase in particle size improves the disintegration and dissolution of tablets. This attributes to the efficient formation of hydrophilic networks by larger size particles. Degree of substitution relates to the total acidic (acid form) and basic (sodium salt) components of superdisintegrants.

What affects disintegration of tablets?
Binders, lubricants, and hardness were found to differ in their effects on disintegration, and these factors are discussed. One two-factor interaction was found and shown to be due to a greater effect of hardness on tablets made with gelatin binder.
Which of the following method enhance the intensity of disintegration?
Explanation: Velocity of degradation, time of process, composting process methods enhance the intensity of disintegration thereby producing better compost, whereas, recycling is used to recycle the wastes and not produce compost.
Why is the disintegration of a tablet important?
Why do we do it? Like dissolution testing, Disintegration is often a pharmacopoeial testing requirement for the vast majority of solid dosage forms. It provides critical safety data on drug bioavailability in the body without having to utilise in vivo methods.
What causes disintegration?
Physical weathering causes the disintegration of rock by mechanical processes and therefore depends on the application of force. Disintegration involves the breakdown of rock into its constituent minerals or particles with no decay of any rock-forming minerals.
How can I improve my disintegration time?
A reduction of the tablet disintegration time was obtained by means of an increase of the granulation moisture; by an increase of the fine fraction; or by a reduction of the lubricant concentration or the compression force.
Which tablet has longer disintegration?
Which tablets have longer Disintegration time? Explanation: Disintegration time is the time taken by the capsule to disintegrate into smaller particles. Enteric coated tablets are coated to protect the drug from the acidic environment of the stomach. Sugar coated ones have long DT.
What is disintegration in tablets?
MECHANISM OF TABLET DISINTEGRATION. Disintegration refers to the mechanical break up of a compressed tablet into small granules upon ingestion and therefore it is characterised by the breakdown of the interparticulate bonds, which were forged during the compaction of the tablet.

uncoated tablets pass the test if each of the six uncoated tablets disintegrates3 in not more that 45 minutes; plain coated tablets pass the test if each of the six plain coated tablets disintegrates in not more than 60 minutes.
What is the principle of disintegration?
Complete disintegration is defined as that state in which any residue of the unit, except fragments of insoluble coating or capsule shell, remaining on the screen of the test apparatus or adhering to the lower surface of the disk, if used, is a soft mass having no palpably firm core.
How is disintegration test carried out?
To carry out a disintegration test for tablets, we use a basket which holds 1 to 6 tablets. This is then raised and lowered into a beaker of water, which is used to simulate conditions in the stomach at 37°C.
What is degradation and disintegration?
is that degradation is (geology) a gradual wearing down or wasting, as of rocks and banks, by the action of water, frost etc while disintegration is (geology) a wearing away or falling to pieces of rocks or strata, produced by atmospheric action, frost, ice, etc.
