Non-aqueous system are well known as solvent or drug suspension vehicles and oleogels micro emulsion with no aqueous phase (anhydrous, non-aqueous oil-in-oil emulsion) have had relatively scant attention yet may have uses as drug reservoir as well as template for the preparation of microemulsion combination with a cosurfactant. Microemulsions have emerged as novel vehicles for drug delivery whi...

(TDDS), additionally called ‘ Transdermal patches,’ square measures dose form design to deliver a The human skin is readily accessible surface for drug delivery. Drug Delivery Systems therapeutically effective quantity of across patients skin. In order therapeutics agents through the systemic effect, comprehensive morphological , biophysical and physicochemical properties are be considered. del...

this review presents a brief outline of our current knowledge of the structure and chemical composition of the outer membrane vesicles (omvs), originating from the surface of gram negative bacteria including their outer membrane proteins and lipopolysaccharides. moreover, the functional roles and applications of omvs in medical research such as omv-based vaccines, omv adjuvants properties, omv ...

intravitreal injection is the most common approach for drug delivery to the posterior segment in humans. however, following the injection, drugs are rapidly eliminated from the vitreous, with half-lives up to a few days. depending on the rate of clearance from the vitreous, large boluses and frequent administrations may be required to ensure therapeutic levels over an extended period of time. m...

Chitosan with excellent biodegradable and biocompatible characteristics has received attention as an oral drug delivery vehicle for controlled-release formulations. In this study an enteric-coated capsule containing theophylline-chitosan beads based on 23 factorial designs was prepared as a colon drug delivery system. The theophylline-chitosan gel beads were formulated by adding the drug-contai...

Microfluidics is undoubtedly an influential technology that is currently revolutionizing the chemical and biological studies by replicating laboratory bench-top technology on a miniature chip-scale device. In the area of drug delivery science, microfluidics offers advantages, such as precise dosage, ideal delivery, target-precise delivery, sustainable and controlled release, multiple dosing, an...

The controlled release of drugs in slow and sustained manner is one of the major challenges in drug delivery system. Targeting of drug to the particular site is an important aspect of drug delivery system. Microparticles were initially developed as carrier for vaccines & anticancer drugs. They have now been used to increase the efficiency of drug delivery system & improve release profile & for ...

Drug delivery systems, particularly nanomaterial-based drug delivery systems, possess a tremendous amount of potential to improve diagnostic and therapeutic effects of drugs. Controlled drug delivery targeted to a specific disease is designed to significantly improve the pharmaceutical effects of drugs and reduce their side effects. Unfortunately, only a few targeted drug delivery systems can a...

nowadays apphcanon of nanotubes in biology and medicinal science is more investigated. nanotubes can passthroueh cell walls and transport and release drugs in special tissues. the purpose of this paper is to investigatethe interaction of a nanotube having hydroxyl functional groups (oh) with an anticancer agent. in this worktransporting of an anticancer drug named 2-(2-amino 6,7-dimethyl pterid...

carvacrol is one of the main components of the eo of some labiatae (laminaceae) members like oregano, thyme and savory. carvacrol has a lot of health benefits for example, antibacterial, and antioxidant activity.we synthesized some silicon derivatives of carvacrol, and characterized them by standard methods. then the monomer of dimethylvinylsilyl carvacrol was synthesized. copolymer of this mon...
