Friability refers to the tendency of tablets to chip, crumble, or break under mechanical stress during manufacturing, packaging, transportation, or handling. High friability compromises the integrity and efficacy of immediate-release tablets, affecting their therapeutic performance and patient compliance. Minimizing friability ensures tablets maintain their physical and chemical properties throughout their lifecycle.

Rapid degradation of immediate-release tablets can compromise drug efficacy, safety, and shelf life. Factors such as moisture, heat, light, and oxygen exposure can lead to physical changes like discoloration or chipping, and chemical changes like API degradation. Addressing these challenges is essential to maintain product quality and regulatory compliance.

Powder segregation occurs when particles of different sizes, densities, or shapes separate during handling, mixing, or transfer. In immediate-release tablet blends, segregation can lead to inconsistent tablet weight, poor content uniformity, and compromised therapeutic efficacy. Preventing segregation is essential to ensure product quality and regulatory compliance.
