Recent years have shown that nasal route can be a potential route for the systemic delivery of protein/peptide drugs as it has a considerably large absorption area (150cm2) which is highly vascularized and has permeability similar to or higher than the small intestinal mucosa. Nasal delivery of protein/peptide drugs also offers other benefits such as ease of administration, noninvasive administ...

BACKGROUND Nasal CPAP is widely used in neonatal ICUs. Aerosolized medications such as inhaled steroids and β agonists are commonly administered in-line through nasal CPAP, especially to infants with bronchopulmonary dysplasia. We hypothesized that aerosol delivery to the lungs via variable-flow nasal CPAP in an in vitro model would be unreliable, and that the delivery would depend on the posit...

Intranasal route, ensuring suitable bioavailability of medicines under circumvention of the gastrointestinal degradation and hepatic first-pass elimination, has been a popular choice for drug delivery. Among nasal dosage forms, mucoadhesive solid inserts have been shown to resist mucociliary clearance and provide a prolonged nasal residence time. Hence, the purpose of this study was the prepara...

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...

The objective of the present study was to formulate and evaluate nasal delivery system contains Ondansetron hydrochloride 4 mg/ml. Ondansetron hydrochloride loaded colloidal dispersion were prepared for nasal drug delivery using various polymers like β-cyclodextrin, hydroxyl propyl βcyclodextrin at different concentrations. The optimized formulation contains 0.02% benzalkonium chloride as a pre...

Migraine is characterized by attacks of moderate to severe intensity headache, associated with some combination of severe disability, autonomic dysfunction such as gastric stasis, poor absorption from the small bowel, and associated symptoms such as nausea, vomiting, phonophobia, photophobia and worsening with exertion [1,2]. Oral medications may not be ideally suited for those migraineurs with...

BACKGROUND Different delivery modes may affect the susceptibility to allergic diseases. It is still unknown whether early intervention with probiotics would counteract this effect. OBJECTIVES The effect of different delivery modes on immune status and nasal symptoms was investigated on established allergic rhinitis (AR) mouse model. In addition, the immunoregulatory effects and mechanisms of ...

Nasal sprays and aerosols are becoming increasingly popular methods for drug delivery. The nasal route is a non-invasive way of administering drugs with rapid uptake into the bloodstream and is considered to be important for the systematic delivery of proteins and other macromolecules. A key parameter in defining the efficiency of nasal aerosol delivery systems is the particle size distribution...
