There is increasing concern about the quality of pharmaceuticals, especially generics made in Asia. Popular books and news reports have the public questioning the quality of pharmaceuticals. Recalls and import bans shake confidence in medications, particularly for active pharmaceutical ingredients and finished dosage forms made outside the United States. The Food and Drug Administration uses geography to allocate resources for manufacturing surveillance. Site of manufacturing labeling, including the country, could be linked to the facility’s quality score to assess the risk of poor quality. Clinicians should advocate for legal and regulatory changes to increase the transparency of pharmaceutical manufacturing of products.

Tablet manufacturing involves the processing of raw materials through several unit operations. Thus, the mitigation of input-induced variability should also consider the downstream processability of intermediary products. The objective of the present work was to study the effect of variable raw materials and processing conditions on the compression properties of granules containing two active pharmaceutical ingredients (APIs) and microcrystalline cellulose. Differences in compressibility and tabletability of granules were highlighted in function of the initial particle size of the first API, granule polydispersity and fragmentation. Moreover, interactions were underlined with the atomizing pressure. Changing the supplier of the second API was efficiently controlled by adapting the binder addition rate and atomizing pressure during granulation, considering the starting crystal size. By fitting mathematical models on the available compression data, the influence of diluent source on granule compactibility and tabletability was identified. These differences resumed to the ease of compaction, tableting capacity and pressure sensitivity index due to variable water binding capacity of microcrystalline cellulose. Building the design space enabled the identification of suitable API types and the appropriate processing conditions (spray rate, atomizing pressure, compression force) required to ensure the desired tableting performance.

The most significant aspect of a drug's physicochemical nature is its solubility. If the medicine is in a dissolved form, it can dissolve and enter the membrane, resulting in a therapeutic effect. The pharmacokinetic phase of the drug in the body, which includes absorption, distribution, metabolism, and excretion, will be correlated with solubility. Some medications, however, have a low solubility. To obtain a therapeutic impact, an effort must be made to increase the drug's solubility. Based on the literature research, the goal of this paper is to explain approaches that can be utilized to improve solubility. In general, physical, chemical, and micelle formation efforts can all be used it to enhance solubility. Particle size reduction, crystal shape modification, and the utilization of matrices in the disperse phase are examples of physical alterations. pH adjustment, buffering, salt formation, complexation, and derivatization all are examples of chemical alterations. The employment of supercritical processes in solutions and also excipients such as surfactants, cosolvents, stabilizing solutions, and others are examples of how micelle formation can be modified.
