Intranasal administration is an attractive option for local and systemic delivery of many therapeutic agents. The nasal mucosa is – compared to other mucous membranes – easily accessible and provides a practical entrance portal for small and large molecules. Intranasal administration offers a rapid onset of therapeutic effects, no firstpass effect ,no gastrointestinal degradation or lung toxici...
Most drugs cannot be given orally because of significant degradation in the GIT or first pass metabolism in the liver. Nasal route for the delivery of some drugs offers an alternative in the pharmaceutical industry. The present review deals with the utility of the nasal route for the delivery of drugs to the brain as a microemulsion system in the treatment of a number of ailments like migraine,...
INTRODUCTION Use of submicrometer particles combined with condensational growth techniques has been proposed to reduce drug losses within components of high-flow nasal cannula therapy systems and to enhance the dose reaching the lower respiratory tract. These methods have been evaluated using continuous inhalation flow rather than realistic inhalation/exhalation breathing cycles. The goal of th...
Intranasal administration provides a non-invasive drug delivery route that has been proposed to target macromolecules either to the brain via direct extracellular cranial nerve-associated pathways or to the periphery via absorption into the systemic circulation. Delivering drugs to nasal regions that have lower vascular density and/or permeability may allow more drug to access the extracellular...
Unpreserved nasal sprays are the latest trend in nasal drug delivery. Different technologies are discussed here in the context of mechanically protected systems, which may provide additional benefits. New test protocols are suggested to evaluate the improved microbiological protection that can be achieved.
Almost 40% of active Pharmaceutical ingredients have low oral bioavailability, high hepatic first-pass metabolism and also less efficient in crossing the blood brain barrier for brain targeting through oral delivery. To overcome this problem the various system such as: nasal spray, gels, emulsions, droplets, suspensions, powders and thermoreversible mucoadhesive gels etc have been studied for n...
INTRODUCTION Lobular capillary hemangioma (LCH) is a benign lesion of vascular origin. It rarely involves nasal cavity which most commonly manifests as progressive nasal obstruction and epistaxis. CASE REPORT In this report we present a case of LCH of the nasal cavity which occurred approximately one month after delivery. There was no recurrence after complete endoscopic resection during one ...
INTRODUCTION Fungal infection of the paranasal sinuses is an increasingly recognized entity both in immunocompetent and immunocompromised individuals. Treatment has been via use of either surgical or medical modalities, or a combination of the two. Here, we present a case of utilization of intra-antral application of an anti-fungal agent in the management of recurrent fungal sinusitis in an ind...
BACKGROUND Nasal cycling may present negative consequences for oxygen-dependent patients using a nasal cannula. This study investigates the effects of nasal cycling on the delivered F(IO2) via nasal cannula in an anatomic model following a baseline study comparing right and left prong nasal cannula oxygen flow delivery. METHODS Flow from right and left nasal cannula prongs were measured simul...
