Nanosuspension is a novel drug formulation for the delivery of hydrophobic drugs. The problem medications that are poorly water-soluble and have low bioavailability countered by nanosuspension technology. Solubility significant physiochemical element influences absorption therapeutic effectiveness. Poor aqueous solubility has potential to impair development. technology can improve drug's stabil...

In the present update on ocular drug delivery system, particulate carrier, the tremendous advances in ocular drug delivery system, the polymers used in particulate carriers for ocular dosage forms, the use of drug complexes and other technological advances are discussed. This review focuses on recent literature regarding mucoadhesive particulate dosage forms with special attention to in vivo st...

Several drug delivery systems have been proposed to overcome physiological barriers, improving ocular bioavailability. Systemic routes are seldom used due to the blood-ocular barrier. Novel drug delivery systems based on nanotechnology techniques have been developed to overcome ocular physiological barriers. This non-systematic review suggests the utilization of a transitory blood-ocular breakd...

Objective(s):  The aim of this study was to prepare a nanosuspension formulation as a new vehicle for the improvement of the ocular delivery of vitamin A.  Material and Methods:   Formulations were designed based on full factorial design. A high pressure homogenization technique was used to produce nanosuspensions. Fifteen formulations were prepared by the use of different combinations of surfa...

The chronic glaucoma with open angle is the second leading cause of blindness in the world. Ophthalmic drug delivery is one of the most interesting and challenging endeavors facing the pharmaceutical scientist. Poor bioavailability of drugs from ocular dosage form is mainly due to the tear production, non-productive absorption, transient residence time, and impermeability of corneal epithelium....
