All product lines are supported by proprietary technologies, and research and development activities are considered to be of a core importance for the business. The IP estate is also available for commercialization, particularly in the prescription area, for which several drug delivery systems and a prescription version of Inflacin were developed. 

Fundamental distrust of the industry s ethics. The public realisation that research studies have been withheld from public view, or released in partial (and misleading) form, has created enormous pressures for industry to make information on all trials available via the internet. The delays in relabelling products, the precipitous withdrawal of widely marketed drugs and the failure to identify safety risks before approval (even when it was not scientifically possible to do so) gives support to the canard that companies put profits before people. And prosecutions of major companies for... 

DMFs are generic dossiers filed with the FDA in order to allow the API to appear in marketed drugs. Thus an API manufacturer files just one application for a product, which can then be used to support approval of any generic based on that API. 

To Support Product Development. In addition to supporting the use of clinical trial materials, stability studies are carried out on both the API and different formulations in different container-closure systems to guide the development of the final formulation and container-closures. Stability studies may be carried out on either the formulation to be marketed or a representative formulation to evaluate different API suppliers, drug product manufacturing processes and sites, and drug product container-closures. 

A company may also submit a supplemental NDA(sNDA) for certain types of modifications to a drug product for which the company is the NDA holder. A firm may submit an sNDA to market a drug product for which it already has approval but, for example, in a different strength or dosage form or for a new indication. Typically FDA will only ask for information in the sNDA, which could include data from further clinical trials, to support the safety and efficacy of the change or modification.
