Why is a friability test important?

Why is a friability test important?

In simple words, friability test tells how much mechanical stress tablets are able to withstand during their manufacturing, distribution and handling by the customer. The strength of a tablet plays a very important role in its marketing and dissolution.

What is the function of friability tester?

Used throughout pharmaceutical industry, friability testers measure the difference between the weight of the sample before and after the process in order to check the physical strength of uncoated tablets.

Why is friability test not required for coated tablets?

It is not only important for dispersible tablets where hardness cannot be increased, but to those tablet as well which are already have proper hardness maintained. This is due to avoid tablet to exhibit any unacceptable capping or excessive wear on the tablet edges or logo while undergoing Coating operations.

Why is the friability tester set at 100 Revolution?

To determine the physical strength of uncoated tablets on exposure to mechanical pressure, Friability test is done. The test can find out the extent of mechanical stress withstandable by the tablets during their manufacturing, distribution and handling processes.

What is the limit for friability of tablets?

A maximum mean weight loss from the three samples of not more than 1.0% is considered acceptable for most products. Conventional compressed tablets that lose less than 0.5% to 1% of weight are considered acceptable, less than 0.5% shows superior friability of tablets.

What is the friability test limit?

1.0 percent

How do you calculate friability test?

Friability test procedure: for friability test, take tablets weight equal to or less than 6.5 g if the unit weight equal to or less than 650 mg. If tablets having a unit weight of more than 650 mg then collect 10 tablets as a whole sample.

How many tablets are used in friability test?

How to perform Friability Test ??? Tablets with unit weight equal to or less than 650 mg, take sample of whole corresponding to as near as 6.5 g equivalent. Tablets with unit weight more than 650 mg, take sample of 10 whole Tablets. Tablets must be de-dusted prior to and after test.

How is friability test done?

This testing involves repeatedly dropping a sample of tablets over a fixed time, using a rotating wheel with a baffle. The result is inspected for broken tablets, and the percentage of tablet mass lost through chipping.

Why dissolution test is performed?

Dissolution testing measures the extent and rate of solution formation from a dosage form, such as tablet, capsule, ointment, etc. The dissolution of a drug is important for its bioavailability and therapeutic effectiveness. Dissolution and drug release are terms used interchangeably.

How can you improve the result of friability testing of tablet?

Doubling the quantity of magnesium stearate in the granulation in one tablet strength decreased the maximum tablet hardness that could be obtained, and for the other tablet strength increased friability.

What is disintegration time of tablet?

Definition. Soluble tablets are uncoated or film-coated tablets that are intended to be dissolved in water giving a clear or slightly opalescent solution. Disintegration test. Soluble tablets disintegrate within 3 minutes when examined by 5.3 Disintegration test for tablets and capsules, but using water R at 15–25° C.

What is the principle of disintegration?

Disintegration is defined as that state in which no residue of the unit under test remains on the screen of the apparatus or, if a residue remains, it consists of fragments of disintegrated parts of tablets component parts such as insoluble coating of the tablets or of capsule shells, or of any melted fatty substance …

What is difference between disintegration and dissolution?

Disintegration is a process of breaking down a substance into tiny fragments to improve its solubility in a solvent. Dissolution, on the other hand, is a process through which solutes dissolve in a solvent. Dissolution is also used predominantly in pharmaceutical industries to check how soluble a drug is in the body.

What are the types of tablets?

What are the two types of capsules?

The two main types of capsules are:

• Hard-shelled capsules, which contain dry, powdered ingredients or miniature pellets made by e.g. processes of extrusion or spheronization.
• Soft-shelled capsules, primarily used for oils and for active ingredients that are dissolved or suspended in oil.

What is the most common capsule size?

size 00

What material is used for capsules?

Capsules are made up of gelatin (hard or soft) and nongelatin shells generally derived from hydrolysis of collagen (acid, alkaline, enzymatic, or thermal hydrolysis) from animal origin or cellulose based.
