one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
discussion while this novel type of drug delivery is known as a suitable substitute for oral and parenteral administration, it was well accepted and extensively mentioned in persian medical and pharmaceutical manuscripts and other traditional systems of medicine as well. accordingly, medieval pharmaceutical standpoints on nasal dosage forms could still be an interesting subject of study. theref...
objective(s): drug delivery via mucosal routes has been confirmed to be effective in inducing strong immune responses. liposomes could enhance immune responses and mucoadhesive potentials, make them useful mucosal drug delivery systems. coating of liposomes by mucoadhesive polymers succeeded in enhancing immune responses. our studies aim at preparation and characterization of trimethylchitosan-...
Nasal drug delivery has now been recognized as a promising route for drug delivery due to its capability of transporting a drug to systemic circulation and central nervous system. Though nasal mucosa offers improved bioavailability and quick onset of action of the drug, main disadvantage associated with nasal drug delivery is mucocilliary clearance due to which drug particles get cleared from t...
the objective of the present work was to formulate and evaluate mucoadhesive in situ nasal gels of loratadine. this drug delivery system may overcome the first-pass metabolism and subsequently improve the bioavailability of the drug. a total of 16 formulations of in situ nasal gels were prepared using different polymeric ratios of hydroxypropyl methylcellulose (hpmc k-100) and xanthan gum. all ...

Nasal route of drug delivery is commonly known for treatment of local ailments like-cold, cough, rhinitis etc. Recently, efforts have been made to deliver various drugs, specially peptides and proteins, through nasal route for systemic use; utilizing the principles and concepts of rate controlled drug delivery and various polymers and absorption promoters. Considering the large number of proble...
Intra nasal drug delivery system (INDDS) has emerged as a noninvasive alternative for delivering peptides, proteins and other therapeutic agents, specifically to CNS (Central nervous system). This route is well suitable for systemic delivery because of high vasculature, permeability, elimination of hepatic first pass metabolism and low enzymatic environment of the nasal cavity. This route of de...
the nasal cavity possesses many advantages as a site for drug delivery, such as, ease of administration, applicability for long term treatments and a large surface area for absorption. one important limiting factor for nasal drug delivery is the limited time available for absorption within the nasal cavity due to mucociliary clearance. several drug delivery systems including different kinds of ...
