Formulation and Drug Delivery

Bioequivalence with the reference product is the only reliable measure of demonstrating the therapeutic equivalence of a generic product to the innovator product. Systematic and comprehensive innovator product characterization can be used to make generic product development easier. This involves characterization of API and quantification of the critical excipients. The latter contributes towards performance of the final dosage form. This article describes the capsule formulation of a poorly water-soluble drug, celecoxib, which contains sodium lauryl sulphate as a critical excipient. The importance of a decoding process aimed at developing a generic product that matches the innovator formulation in a discriminating dissolution method is demonstrated.

The US Department of Health and Human Services (HHS, Washington, DC) will distribute more than $1 billion in contracts to accelerate the development of cell-based production technologies for influenza vaccines.

Using Bezier curves, an experimental process controller has been developed for biosynthesis applications in which the inactivity of a pH-sensitive enzyme must be decreased. By taking into account various control scenarios of pH and growth rate, as well as the physical and chemical characteristics of the environment, a suitable human-machine interface can be developed.

Manufacturing and formulation innovation spurs drug develop-ment, but raises new safety and quality issues.

Novartis (Basel, Switzerland) has closed on its $5.4-billion acquisition of Chiron Corporation (Emeryville, CA), paving the way for the creation of a new Novartis division focusing on vaccines and diagnostics.

This review article discusses orally disintegrating tablets and their manufacturing technologies, development issues, and future trends.

The common crystal form of ibuprofen was changed to optimize processing and manufacturing properties. Six modified crystal forms were prepared and assessed for dissolution, morphology, particle size, density, thermal characteristics, powder x-ray diffractometry, flow properties, and tabletability.

Sandoz (Holzkirchen, Germany), the generics division of Novartis (Basel, Switzerland) received European marketing authorization for its recombinant human growth hormone, ?Omnitrope? (somatropin), making it the first biogeneric product approved under the biosimilar pathway of the European Commission.

Being the first to gain the most is a fundamental principle in the generics business because several companies compete to create generics of successful products going off patent. For a generics company to maintain revenue growth in a market in which product prices continue to fall, it must secure a continuous flow of new products, with quality and speed to market being key drivers. Thus, generics companies must be highly skilled in product and process development (1), the generics business, and achieving bioequivalence-the most critical development area.

Absorption promoters and enhancers and enzyme inhibitors, either alone or in combination, can play an important role in improving the bioavailability of oral insulin.

Cell-culture technology and financial incentives give influenza vaccine makers a much-needed shot in the arm, but many downstream processing issues remain unaddressed.

Could compounds in chocolate yield new pharmaceutical approaches to major disorders?

The discovery of suitable lead structures for new drugs from an inexhaustibly large reservoir of theoretically possible compounds is one of the biggest challenges for the pharmaceutical industry. In the last few years, combinatorial chemistry methods have been developed to synthesize a huge amount of diverse new chemical entities (NCEs), which may subsequently be tested for biological activity in vitro.

Pellets are a multiparticle, solid form of medication. The individual pellets are almost spherical with diameters usually between 100 and 2000 ?m.

Creation and qualification of scale-down models are essential for performing several critical activities that support process validation and commercial manufacturing. As shown in Figure 1, these activities include process characterization and production support studies that are performed to evaluate column and membrane lifetimes, demonstrate clearance of host-cell impurities and viruses and troubleshoot manufacturing issues. While the underlying fundamentals are relatively the same as those when scaling up, some unique considerations should be taken when scaling unit operations down.4
