The Lean Management had its origin in the 50s in the Japanese automobile industry, and is currently used in different production processes, included those related to pharmaceutical production, for which has raised its application in the manufacture of loperamide HCl-orodispersible tablets (HCl-ODT) under the coordination of the Pharmaceutical Quality System (PQS). A theoretical proposal for process reengineering has been carried out both incorporating and applying the different Lean tools in the industrial manufacturing process of HCl-ODT, and their subsequent integration into the PQS, through each one of the processes stages, such as: weighing, screening, mixing, compression, and packaging, under the compliance of the current legislation of the pharmaceutical industry and in compatibility with what is established in the ICHs within the Quality System, in order to increase the effectiveness and efficiency of the process and its profitability. Lean Management under the coordination of the Pharmaceutical Quality System (PQS), is an excellent strategy for manufacturing loperamide HCl-orodispersible tablets since it improves its Quality System, as well as facilitates compliance with the national and international guides, standards and legislation that are suitable to it.

Ferric hexacyanoferrate, Fe4 [Fe(CN)6]3 · xH2O, known as Prussian blue (PB), has proven its effectiveness as an antidote in cases of accidental poisoning or poisoning caused by radioactive materials such as cesium (Cs) and thallium (Tl); which due to their solubility in water, when absorbed by the human body, cause serious damage to vital organs. The local development of a drug with PB as an active ingredient arises as a response to the civil and military needs established within the Ministry's pharmacy request for national defense. This fact contemplates the circumstances related to public health protection in the nuclear, radiological, biological and chemical (NRBQ) of the emergency institutions in health and national security. In this paper and by using various analytical techniques, the characterization of the locally synthesized PB with pharmaceutical quality has been described, as a first step to predict its behavior in the preparation of a drug that contains it as an active ingredient.The research findings demonstrate that locally synthesized PB is suitable for use in oral dosage forms, enabling the local development of drug formulations incorporating PB, thus being able to potentially become a main resource in the treatment of Cs and Tl poisoning in any accidental or intended of the population. This development opens up the possibility of creating drug formulations that incorporate PB at a local level, making it a potentially significant resource in the treatment of Cs and Tl poisoning. The ability to locally produce and utilize PB in oral dosage forms could be crucial in addressing cases of accidental or intentional exposure within the population. This advancement not only contributes to the scientific understanding of PB but also holds promising implications for practical applications in public health and emergency situations.

Objectives: Potassium iodide (KI) is a treatment to neutralize radioactive agents that could be inhaled or ingested in nuclear incidents. The inorganic salt KI constitutes a source of iodine, which in the body acts by accumulating in the thyroid gland, producing its saturation, and thus preventing the fixation of radioactive iodine species. In Spain, the Military Defence Pharmacy Centre (CEMILFARDEF) was challenged to develop this antidote to be distributed among the population surrounding nuclear power plants, in only one new solid pharmaceutical form for oral administration, in order to replace the two pharmaceutical forms available, which are capsules for adults and oral solution for children, considered less versatile. Methods: A selection of excipients was carried out to achieve pharmacotechnical behaviour suitable for the industrial manufacture of potassium iodide in tablets, complying with the pre-established process and finished product quality parameters. The development allowed the preparation of three industrial-sized batches on which the stability of the developed formulation was studied. Results: An uncoated 65 mg double-scored potassium iodide tablet was developed using easily accessible excipients in the formulation and direct compression as the manufacturing method. The formula complied with the stability tests, with which the development carried out can respond to the eventual demand that its elaboration would entail in the event of nuclear incidents. Conclusions: The developed formulation of a 65 mg double-scored potassium iodide tablet allows the great variability of user needs, from infants to adults with a single pharmaceutical form, which additionally implies logistical benefits in distribution, stock control and appropriate renewal according expiration dates, among the population surrounding nuclear power plants and available to deployed military personnel, in the event of potential nuclear incidents.
