Lipid Emulsions as Drug Delivery Systems

Introduction

Recent advances in combinatorial chemistry techniques employed in the pharmaceutical industry have dramatically increased the number of new compounds for evaluation as drug candidates. Approximately half these new chemical entities contain hydrophobic substituents that result in the compounds exhibiting poor aqueous solubility. This lipophilic attribute offers the capability in tailoring the formulation of a new chemical entity into a lipid emulsion drug delivery system to accommodate the specific requirements of the disease with respect to stability, toxicity and efficacy in parenteral administration.

Types of Emulsions for Parenteral Drug Delivery

An emulsion is a dispersion of two or more immiscible liquids stabilised by a surfactant or emulsifier coating the droplets and preventing coalescence by reducing interfacial tension or creating a physical repulsion between the droplets (1). Two common types of emulsions are found in parenteral drug delivery systems. Water in oil emulsions (W/O) are used in sustained release of steroids and vaccines by intramuscular injection. Oil in water (O/W) or lipid emulsions can be administered by a variety of parenteral routes (for example subcutaneous, intramuscular, intra-arterial), but are predominantly injected intravenously in parenteral nutrition applications.

4th Annual Patient Recruitment and Retention in Clinical Trials

13-15 October 2008, Amsterdam

Patient recruitment is now consuming thirty percent of clinical trial time - more time than any other clinical trial activity - and almost half of all trial delays result from patient recruitment problems. As the recruiting culture becomes more sophisticated and the forces affecting patient enrollment grow more numerous and complex, pharmaceutical companies are striving to discover new strategies to facilitate enrollment in clinical trials. With increasing industry pressure to develop, test and market greater numbers of new drugs faster, pharmaceutical companies need to perform clinical trials as quickly as possible. Inefficient patient recruitment processes is a formidable barrier to pharmaceutical companies' success in launching new products. Improving the patient recruitment process is imperative to avoid wasted investments and eliminate costly delays in bringing new drugs to market -- today and even more so in the not-so-distant future. Improved patient recruitment presents one of the largest opportunities for pharmaceutical companies to eliminate delays in clinical trials, thereby making it possible to reduce time to market.  With patent time limits and large overheads meaning that any delays in the development timeline can be disastrous, a good understanding of how to successfully recruit patients for trials is vital for any company looking to succeed.
