Tablet friability problem

Sticking and picking is a common problem during tablet development and manufacture. It occurs when particles of the tablet formulation adhere to the punch face. Using an adhesion punch specifically designed for this application, the risk of sticking of new formulations or to troubleshoot solutions for existing products can be quantified. high friability. On the other hand, tablets obtained by direct compression are less friable but disintegrate in a longer time. The most important properties of these tablets are: mechanical strength, friability, taste, grittiness and the in vivo disintegration time.

The final batch are prepared by the direct compression method & then evaluated to the physical parameter of the dispersible tablet of ampicillin & cloxcillin & preformed to the wt. variation, hardness, friability & Disintegration time of the tablet accordingly to mentioned in I.P. standard.

  • Tablet friability results in weight loss of tablets in the container owing to partial powdering, chipping, or fragmentation of the tablets on attrition or wear (Gupta, 1940). Tablet friability often reflects lack of cohesiveness and compression of the dry granulation from which the tablets are made.
