Successful homing of drugs to the desired biological compartment of the host usually depends on the intrinsic properties of the drug molecules. However, it can always be manipulated by appropriate designing of the carrier/ delivery system, as little can be done to influence the target and its surroundings. Various carrier systems have emerged to deliver drugs to macrophages, albeit the efficacy, reliability and selectivity of these carriers are still in question. To date, the most extensively studied carriers are liposomes and microspheres. In fact, physicochemical properties of these carriers can alter their efficacy and specificity to a great extent. These properties include hydrophilicity, surface charge, composition, concentration, and presence of various target specific ligands on their surface. Incidentally, the particulate nature of these vehicles may facilitate passive homing of the entrapped drug molecules to the macrophages, which may harbour many of the important pathogens in their intracellular compartments, such as Mycobacterium sps, Leishmania and dengue virus etc., belonging to three different major classes of microbes. Moreover, macrophages upon interaction with particulate drug delivery vehicles may act as secondary drug depot, thus helping in localized delivery of the drug at the infected site. In the present article, a comprehensive review of literature is presented on the suitability of some lipid-based and polymeric materials as vehicles in delivery of drugs to macrophages in parasitic infections.
