Current development in nanoformulations of docetaxel.
Summary of "Current development in nanoformulations of docetaxel."
Introduction: Docetaxel (DTX) has been proven as one of the most important cytotoxic agents, and its clinical ef´Čücacy against many cancers is superior to paclitaxel. DTX in commercial formulation contains the non-ionic surfactant Tween 80 (polysorbate 80) and 13% ethanol; the side effects caused by DTX and the solvent have considerably limited its clinical use. In recent decades, the emergence of nanoformulations provides new modes of actions in DTX. Many nano-sized carriers can help DTX transport through leaky tumor capillary fenestrations into the tumor cells. Moreover, these particles can be modified for binding to specific sites such as cancer cell membranes, cytoplasmic or nuclear receptors. Areas covered: The authors focus on nanoformulations related to DTX delivery, covering their preparation, physicochemical properties and the in vitro and in vivo actions against tumor cells. The challenges involved in the development of nanoformulations for DTX are also discussed. Expert opinion: Although nanoformulations such as liposome, micelle, nanoparticle, nanoemulsion greatly improve the solubility, activity and distribution of DTX in vivo, significant hurdles remain concerning aspects of nanoformulations such as quality control, physicochemical stability, storage conditions, large-scale production and controlled manufacture technology, in vivo metabolism, excretion, acute and chronic toxicity, etc. In-depth studies in these areas are essential to making DTX nanoformulations applicable in clinic and commercially available viable.

Medical and Biotech [MESH] Definitions
Therapeutic introduction of ions of soluble salts into tissues by means of electric current. In medical literature it is commonly used to indicate the process of increasing the penetration of drugs into surface tissues by the application of electric current. It has nothing to do with ION EXCHANGE; AIR IONIZATION nor PHONOPHORESIS, none of which requires current.
Electric Stimulation Therapy
Application of electric current in treatment without the generation of perceptible heat. It includes electric stimulation of nerves or muscles, passage of current into the body, or use of interrupted current of low intensity to raise the threshold of the skin to pain.
Work consisting of a formal report giving details of the investigation and results of a medical or other scientific problem. When issued by a government agency or comparable official body, its contents may be classified, unclassified, or declassified with regard to security clearance. This publication type may also cover a scientific paper or article that records the current state or current position of scientific research and development. If so labeled by the editor or publisher, this publication type may be properly used for journal articles.
Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. Energy sources are commonly direct current (DC-shock) or alternating current at radiofrequencies (usually 750 kHz). The technique is used most often to ablate the AV junction and/or accessory pathways in order to interrupt AV conduction and produce AV block in the treatment of various tachyarrhythmias.
