ABSTRACT
Long-acting injectables (LAIs) and implants are designed to release a drug at a controlled rate for a specic duration and thereby achieve therapeutic drug concentrations for a prolonged period. This chapter describes a variety of LAIs and implant platforms that are currently commercially available, or at an advanced stage of development. This chapter is closely related to Chapter 5, which describes parenteral drug delivery from a targeting perspective, as opposed to the controlled-release perspective that is described here.
