Interest in Lipid Based Drug Delivery (LBDD) is relatively recent and relates to the developments in the past 10 to 15 years, largely driven by the growing need for novel drug delivery systems to deal with the vast majority of the new chemical entities (NCE) that have poor solubility or permeability, to improve the delivery of existing drugs, and for line extensions. Other applications include drug coating for either taste masking or protection of the active, and in sustained release dosage forms. Successful drug design with lipids depends largely on understanding the physical-chemical and physiological factors that promote or inhibit bioavailability. It requires a grasp of not only the drug candidate issues but also the role of the drug delivery system or the potential for drug-excipient interplay in vitro as well as in vivo conditions. Depending on the choice of excipient(s) and formulation techniques, it is possible to obtain a variety of systems including physical mixtures, liquid/solid solutions, solid dispersions, and Self-Micro or Self-Nano Emulsifying Drug Delivery Systems (SMEDDS/SNEDDS). These systems may then be incorporated into tablets by absorbing on to absorbents.
