Nasal drug delivery may be used for either local or systemic effects. Low molecular weight drugs with are rapidly absorbed through nasal mucosa. The main reasons for this are the high permeability, fairly wide absorption area, porous and thin endothelial basement membrane of the nasal epithelium. Despite the many advantages of the nasal route, limitations such as the high molecular weight (HMW)...
In most circumstances, a nasal route for the delivery of pulmonary aerosol medications is rarely considered; however, in specific instances, this route may be quite useful. Consider, for example, the delivery of aerosol treatments during humidified high-flow nasal cannula use in pediatric critical care, or continuous aerosol delivery via cannula for medications with short durations of action. T...
The aim of this review is to provide information regarding significant aspects and challenges in developing nasal sprays. This article outlined the relevant anatomy, physiology & biological, physicochemical pharmaceutical factors that must be considered during formulation development Nasal drug delivery system most preferable route than other routes administration as it gives rapid onset ac...
Since ancient times, drugs have been administered via the nasal route for therapeutic and recreational purposes. The interest in, and importance, of the systemic effects of drugs administered through the nasal route, have expanded over recent decades. Intra-nasal administration of drugs offers an interesting alternative for achieving systemic therapeutic effects of drugs that are comparable to ...
We have used the carbon dioxide (CO(2)) laser and the gallium aluminium arsenide (GaAlAs) diode laser with flexible fiber delivery instruments for vaporization of the inferior nasal turbinate in pediatric patients since 1993. Under endoscopic control, the whole inferior turbinate was vaporized by 5-10 W laser output delivered via an optical fiber. Generally, the nasal mucosa changes into normal...
Recently, intranasal delivery of insulin as an alternative route of parenteral administration has been widely studied because it bears close resemblance to the 'pulsatile' pattern of endogenous insulin secretion during meal time. However, insulin is not well absorbed through nasal mucosa because of its large molecular size, hydrophilicity and low permeability through the membrane. This review d...
Topical drug delivery to poorly ventilated paranasal sinuses is challenging. Pulsating aerosols can improve the deposition of drugs like cortisol in sinuses. The current study compares effect Budesonid administered as pulsating aerosol comparison conventional nasal spray
A new anthrax vaccine under clinical investigation is based on recombinant Bacillus anthracis protective antigen (rPA). Here, we investigated microneedle-based cutaneous and nasal mucosal delivery of rPA in mice and rabbits. In mice, intradermal (id) delivery achieved up to 90% seroconversion after a single dose, compared with 20% after intramuscular (im) injection. Intranasal (inl) delivery of...
