The safety and efficacy of pharmaceutical products (e.g., tablets/capsules) can only be established by determining the quality of the products. If the quality of the products cannot be established, as currently is the case, then claims of safety and efficacy cannot be made either. In addition, as compliance does not necessarily equate to quality, safety and efficacy cannot be achieved by compliance as well. Use caution in promoting or accepting such claims. The products’ quality, safety, and efficacy must be defined and determined independently.
Please seek a definition of the quality of pharmaceutical products in terms of a quantifiable parameter. The following links would be useful (1, 2, 3).
