Packaging/containers
It must be remembered that the container will also come into direct contact with the pharmaceutical product. Careful consideration should therefore be given to the material and composition of the container. The manufacturer must clearly communicate medical grade specifications because the supplier of the container does not necessarily know the level of quality requirements.
In tropical countries, plastic containers, for example, may not be recommended due to interactions between container/content or between powders and container walls. Adsorption of plastic materials will also modify the stability of the product. Intolerance reactions or toxic phenomena can result from the stability modifications of the product following a shift in content constituents and adherence to the sides of the container.
