Vitreoretinal diseases are refractory to both topical and systemic pharmacological approaches because of specific environment of the eye. That is, the cornea, the sclera, nasolacrimal drainage of tears, frontward stream of aqueous humor, blood-aqueous barrier, and blood-retinal barrier strictly limit penetration and diffusion of drug into the retina. However, recent advances in intraocular drug delivery systems (DDS) have Read More

Transdermal drug delivery offers certain advantages over conventional oral or parenteral administration. However, transdermal delivery is not available to many promising therapeutic agents, especially high molecular weight hydrophilic compounds. This is due to the excellent barrier property of the superficial skin layer, the stratum corneum (SC). Only drugs with very specific physicochemical properties (molecular we Read More

In this paper, a comprehensive review of recent patents concerning the molecular self-assembly of peptides, peptide amphiphiles and peptidomimetics into molecules through nanoarchitectures to hydrogels is provided. Their potential applications in the field of drug delivery and tissue engineering have been highlighted. The design rules of this rapidly growing field are centered mainly on the construction of peptid Read More

Oral combination drug delivery systems have been proven to be highly beneficial and vital in the treatment of several dreadful diseases such as cancer, HIV (AIDS) and tuberculosis. Further, pharmaceutical companies have often explored the strategy of combination drug therapy for treating diseases such as diabetes (Type 2), cardiovascular diseases, central nervous system (CNS) disorders, and for treating several other micr Read More

Pellets exhibit major therapeutic and technical advantages which have established them as an exceptionally useful dosage form. A plethora of processes and materials is available for the production of pellets, which practically allows inexhaustible configurations contributing to the flexibility and versatility of pellets as drug delivery systems. The scope of this review is to summarize the recent literature on pelletization process Read More
