in induction of systemic and mucosal immunity, particulate antigens are more effective than soluble antigens possibly because they are more efficiently endocytosed by mucosal-associated lymphoid tissue (malt) m cells. in this study, we determined the systemic and mucosal immune responses in rabbits following intranasal immunization of tetanus toxoid tt and cpg-odn encapsulated within plga nanos...

The principal routes of cocaine administration are oral, intranasal, intravenous, and inhalation. The slang terms for these routes are, respectively, "chewing," "snorting," "mainlining," "injecting," and "smoking" (including freebase and crack cocaine). Cocaine use ranges from occasional use to repeated or compulsive use, with a variety of patterns between these extremes. There is no safe way t...

with low oral bioavailability due to to extensive gastrointestinal breakdown or high hepatic first-pass effect. Intranasal delivery of drugs to reach the system has been widely studied and a number of reports is available in the literature (1). The concentration-time profiles of drugs achieved after nasal administration are often similar to those after intravenous administration, with resultant...

Currently, mucosal vaccine administration has stood out as an easier and non-invasive application method. It can also be used to induce local systemic immune responses. In the COVID-19 pandemic context, nasal oral vaccines have been developed based on different technological platforms. This review addressed relevant aspects of administration, with emphasis vaccinations, in addition importance u...

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...

The clinical effects of an oral administration of a hop water extract (HWE) on the improvement of Japanese cedar pollinosis (JCPsis) symptoms were investigated. In a double-blind, placebo-controlled trial, 39 subjects took a drink containing either 100 mg of HWE or a placebo for 12 weeks during the pollen season. Nasal symptoms (sneezing attacks, nasal discharge, and nasal obstruction) were ass...

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...

is perhaps the most preferred by patients and clinicians alike. However, peroral administration of drugs has disadvantages, such as hepatic first-pass metabolism and enzymatic degradation within the gastrointestinal (GI) tract, that prohibit oral administration of certain classes of drugs, especially peptides and proteins. Consequently, other absorptive mucosa are considered as potential sites ...
