Which strength consider for hold time study of product… Highest or lowest …plz suggest with reference…
The lower and higher strength
For same API or product?? Which one??
For example … Amlodipine tablet 5 mg and 2nd is Amlodipine tablet 10 mg …which one is consider for hold time??
Both will be taken
Generally, the highest strength of the same product should be considered for the ‘Hold time’ study, provided same excipients are used in all the strengths of that product.
