BACKGROUND The gold standard for cobalamin deficiency treatment is administration of cobalamin by intramuscular injection. The injection is painful and inconvenient, particularly for elderly persons. Cobalamin might also be administered intranasally. Previous studies do not provide insight into the pharmacokinetics of intranasal cobalamin administration in comparison with cobalamin injection. ...
Deferoxamine (DFO) is a high-affinity iron chelator approved by the Food and Drug Administration for treating iron overload. Preclinical research suggests that systemically administered DFO prevents and treats ischemic stroke damage and intracerebral hemorrhage. However, translation into human trials has been limited, probably because of difficulties with DFO administration. A noninvasive metho...
OBJECTIVE To investigate how nasally applied substances distribute in the nose depending on the form of application. DESIGN Observer-blinded study. SETTING University hospital research unit. PARTICIPANTS Fifteen healthy volunteers aged 22 to 32 years. INTERVENTIONS Forms of application included (1) nasal drops applied with a pipette, (2) nasal spray, and (3) a system producing squirts. ...
Oxytocin has been implicated in a variety of prosocial processes but most of this work has used laboratory tasks (such as the ultimatum game or the dictator game) to evaluate oxytocin's prosocial effects. In a double blind randomized trial we examined the influence of intranasal administration of oxytocin on real, high-cost donating money to a charity without any expectation for reciprocation. ...
Of several newer delivery systems under development and investigation for the administration of opioids, the intranasal route has received a substantial amount of attention. Intranasal administration is a convenient form of delivery that is applicable to several opioids. It has the potential for self-administration, combined with a rapid onset of action, allowing for patient-controlled analgesi...
Pain is a problem that often has to be addressed in the prehospital setting. The delivery of analgesia may sometimes prove challenging due to problems establishing intravenous access or a harsh winter environment. To solve the problem of intravenous access, intranasal administration of drugs is used in some settings. In cases where vascular access was foreseen or proved hard to establish (one o...
The last two decades has seen progress in the development of potential mucoadhesive carriers for assisting with the oral and nasal administration of drugs based around the polysaccharide chitosan. This progress has been underpinned by the development of molecular assays for mucoadhesiveness focusing on the mucin component of mucus. We review the developments based around molecular or biophysica...
Background: The risk of anesthesia increases with age, so it is necessary to choose a safe and effective method. In this study, we compared the effectiveness of intranasal fentanyl with intravenous fentanyl in patients undergoing cataract surgery. Methods: This study was a triple-blind prospective randomized clinical trial (The patient, physician, and data analyzer were unaware of the patient ...
Objective(s): The Botulism syndrome is caused by types A to G of botulinum neurotoxins. The binding domains of these neurotoxins are immunogenic and considered as appropriate candidate vaccines. Due to the low immunogenicity of recombinant vaccines, there have been many studies on the use of biocompatible carriers such as chitosan nanoparticles for the delivery of these vaccines. The aim of thi...
