Thrombotic diseases, as potentially induced by blood clots or vascular embolization, frequently occur with high rates of mortalities worldwide. Current drug thrombolysis, a primary clinical therapy, may increase fatal risk of hemorrhage when thrombolysis agents become systemically distributed. Given current thrombolysis limitations, some novel drug delivery systems based on nanoparticles have been recently exploited to achieve a more controlled release of loaded thrombolytic agents, able to respond to environmental changes, and resulting in a safer thrombolysis. In this review, the authors outline and discuss some prominent examples of early and recent thrombolytic agent delivery systems using controlled release by physical stimuli (shear, sound and light). Shear-sensitive systems are designed to exploit the specific biomechanical feature of thrombosis, that is, the increased blood shear stress. Sound- and light-sensitive systems reflect "remote control" of drug release by responding to external ultrasound or light stimulus. These smart thrombolytic drug delivery systems hold promise for more effective and safer future thrombolytic therapy.

Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers.
