Patient-friendly Reconstitution a Major Factor in the Growth of Biological Injectables

Safety and Compliance Driving Device Innovation for Protein Drugs according to Greystone Research Associates

(PresseBox) (Amherst, NH, ) Supplying drugs that must be administered as a liquid in solid form has been an approach used to improve drug stability since early in the last century. Lyophilized drugs for injection were traditionally sold in vials packaged with a diluent syringe, but as new proteins and peptides targeting chronic indications reach the market a growing number of these biological drugs are being supplied with devices designed to allow for reconstitution with minimal steps and handling.

The number of drugs supplied in lyophilized form has been growing at an increased rate over the past several years, mirroring the increase in the introduction of biological drugs. Because of stability and shelf life factors, therapeutic proteins must either be stored under special conditions or formulated to retain their efficacy from the time of manufacture until they are dispensed. Liquid protein drugs require refrigeration until dispensed - a distribution strategy referred to as the 'Cold Chain'. Alternatively, proteins can be formulated as powders. These lyophilized proteins must be reconstituted prior to injection.

For lyophilized drugs intended for self-administration, reconstitution must occur at the point of use. To address this requirement, a number of adaptive devices and systems have been designed to reconstitute lyophilized drugs immediately prior to delivery. Reconstitution time of powder for injection is affected by several parameters that must be precisely controlled to develop a product with short and reproducible reconstitution time, thus ensuring patient safety.

The first wave of devices aimed at easing the process of converting a lyophilized drug into an injectable solution focused on vial systems that incorporated a vial adapter or vial transfer device. More recently, dual chamber drug cartridges and syringes go a step further and allow reconstitution to take place within the device immediately prior to injection without the need for the patient to handle vials or diluent.

Currently only a small number of lyophilized drugs are packaged, or bundled, with reconstitution devices - most lyophilized drugs for injection are typically sold in vials packaged with a diluent syringe - but this number is expanding. The high cost-per-unit-dose drugs such as recombinant proteins can easily absorb the incremental cost of point-of-care reconstitution technology. Drug marketers have learned to embrace the added cost of reconstitution systems as a way to differentiate their products in an increasingly competitive pharmaceutical landscape.

Detailed analysis of components and systems for reconstituting drugs at the point-of-care is included in a new and comprehensive report. The report - Drug Reconstitution at the Point-of-Care: Therapeutic Markets, Technologies, Strategies and Prospects - includes assessments of therapeutic market segments, market factors, as well as profiles of market participants.
