Twо tаblet fоrmulаtiоn series аre being assessed:Product X: The API and IPIs are not exactly proportional between strengths, but the ratios of the IPIs to total dosage-form mass fall within the limits in Table 3 of the SAHPRA Variations guideline. Product Y: The API concentration is less than 5 %, the different strengths have similar mass, and differences in API content are compensated by changes in one or more IPIs, with the total mass remaining within 10 % of the bioequivalence-study strength. Which statement is correct?
