This is arguably the most critical safety and efficacy test. It ensures that each tablet in a batch contains the active substance within a narrow range (typically 85–115% of the label claim). The test is performed according to General Chapter 2.9.40, using either content uniformity (individual assay of 10 tablets) or mass variation (weighing tablets for potent drugs). Failure here indicates poor manufacturing mixing or compression, leading to underdosing (ineffectiveness) or overdosing (toxicity).
Tablets must be examined visually to ensure they are not broken, have a smooth surface (unless scored), and are free from obvious defects like cracks or spots.
