background: influenza outbreak has become a great lifethreateningdisease in the world. nasal vaccines can inducesystemic igg and mucosal iga antibody responses, whichestablish two layers of immune defense against the infectiouspathogens like influenza. mucosal vaccines must overcomeseveral limitations, including the mucociliary clearance andinefficient uptake of soluble antigens. therefore, nas...

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...

A time-course study was performed to assess lung concentrations and bioactivities of a fully human monoclonal antibody (mAb) targeting Pseudomonas aeruginosa (PA) flagella type b (LST-007) following intra-nasal administration. Intra-nasal administration of LST-007 (5 mg/kg) resulted in high mAb concentrations (11 μg/ml) within the bronchoalveolar lavage (BAL) fluid at 15 min post-administration...

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...

objective: several medications have been used for sedation in children in dentistry and intra-nasal route has been reported to be an efficient way regarding patient cooperation. the aim of the present study was to compare the changes in physiologic parameters following intra-nasal midazolam and ketamine administration.   methods: in this randomized cross-over double-blind trial, 17 uncooperativ...

Drugs used to treat brain or central nervous system disorder suffer from shortfall of absorption and reaching brain due to blood brain barrier and cerebro spinal fluid barrier. Intra nasal administration of brain targeted drug delivery system is gaining popularity to circumvent blood brain barrier and enhance drug availability in brain. It also shows promising reduction of systemic adverse effe...

Non-human primates are the animals closest to humans for use in influenza A virus challenge studies, in terms of their phylogenetic relatedness, physiology and immune systems. Previous studies have shown that cynomolgus macaques (Macaca fascicularis) are permissive for infection with H1N1pdm influenza virus. These studies have typically used combined challenge routes, with the majority being in...

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 ...

Part 2 of this paper deals with the techniques for drug delivery of topical and injectable local anaesthetics. The various routes of local anaesthetic delivery (epidural, peripheral, wound catheters, intra-nasal, intra-vesical, intra-articular, intra-osseous) are explored. To enhance transdermal local anaesthetic permeation, additional methods to the use of an eutectic mixture of local anaesthe...
