OBJECTIVE: In this study, changes occurring in the contractility capacity of the inferior turbinate and mucociliary clearance time due to the interruption of nasal air flow were examined. MATERIAL & METHODS: A total of 23 patients undergone total laryngectomy between June 2010 and June 2012 were included in the study. Acoustic rhinometry test was performed in the patients before and after 0.05% oxymetazoline nasal topical decongestant administration. In addition, saccharin test was applied in order to measure mucociliary clearance...

Nasal blockage is the most bothersome symptom of acute rhinitis. Nasal decongestant sprays containing alpha-sympathomimetics, such as oxymetazoline and xylometazoline, have a rapid onset of action. However, this effect decreases with repeated application and, furthermore, the ciliary function of the nasal mucosa is practically paralyzed. Dexpanthenol promotes cell proliferation and protects the epithelium. Combining these two agents has demonstrated beneficial synergetic effects on the symptoms of acute rhinitis...

BACKGROUND AND PURPOSE: Agonists acting at GPCRs promote biased signalling via Gα or Gβγ subunits, GPCR kinases and β-arrestins. Since the demonstration of biased agonism has implications for drug discovery, it is essential to consider confounding factors contributing to bias. We have examined bias at human α1A -adrenoceptors stably expressed at low levels in CHO-K1 cells, identifying off-target effects at endogenous receptors that contribute to ERK1/2 phosphorylation in response to the agonist oxymetazoline...

In the clinic, approximately 30% of children with adenoid hypertrophy (AH) concomitant with allergic rhinitis (AR) report poor responses to intranasal steroids. To determine whether the combination of mometasone furoate (MF) and oxymetazoline (OXY) is more effective than either agent alone, we performed a two-stage, parallel, randomized, double-blind, double-dummy, clinical trial with 240 AH children with concomitant perennial AR. During the first stage, all children were randomly assigned to the MF or control group for six weeks of treatment...

BACKGROUND: Many treatments for the common cold exist and are sold over-the-counter. Nevertheless, evidence on the effectiveness and safety of nasal decongestants is limited. OBJECTIVES: To assess the efficacy, and short- and long-term safety, of nasal decongestants used in monotherapy to alleviate symptoms of the common cold in adults and children. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 6, June 2016), which contains the Cochrane Acute Respiratory Infections (ARI) Specialised Register, MEDLINE (1946 to July 2016), Embase (2010 to 15 July 2016), CINAHL (1981 to 15 July 2016), LILACS (1982 to July 2016), Web of Science (1955 to July 2016) and clinical trials registers...

Raynaud's phenomenon is frequently observed in systemic sclerosis (SSc) patients, and cold- or stress-induced norepinephrine (NE) has been speculated to be associated with vasoconstriction. Objective was to elucidate the role of NE in fibrosis in SSc. IL-6 is a potent stimulator of collagen production in fibroblasts. NE enhanced IL-6 production and proliferation more significantly in SSc fibroblasts than in normal fibroblasts. Furthermore, the production of IL-6 and phosphorylation of p38 in SSc fibroblasts was enhanced by adrenergic receptor (AR)β agonist, isoproterenol, but not ARα agonist, oxymetazoline...

BACKGROUND: An intranasal formulation of 3% tetracaine and 0.05% oxymetazoline (Kovanaze) received FDA approval on 29 June 2016. This formulation appears to provide sufficient local anesthesia to perform routine dental restorative (filling) procedures in maxillary teeth from second premolar forward. OBJECTIVES: The aim of this paper is to provide an overview of the efficacy, pharmacokinetics and tolerability of 3% tetracaine plus 0.05% oxymetazoline when administered intranasally...

A simple and selective reversed-phase high-performance liquid chromatography method was developed for the estimation of cromolyn sodium (CRM) with either oxymetazoline hydrochloride (OMZ) or xylometazoline hydrochloride (XMZ) in their binary mixtures. The method is based on the simultaneous separation of each drug in a reversed-phase Waters symmetry(®) C18 column (250 mm × 4.6 mm intradermally, 5-µm particle size) at 25°C. Elution was performed with a mobile phase consisting of methanol : 0.1 M phosphate buffer (60:40, v/v, pH 4...

OBJECTIVES: To identify the optimal pharmacological method of preparing patients for nasal endoscopy. METHODS: Twenty healthy volunteers were enrolled in this prospective, randomized, double-blind study. Four types of medications were applied in their nostrils with binary combinations of spray bottles on four different days in a random order: placebo (normal saline [NS]+NS), decongestant (NS+oxymetazoline), anesthetic (NS+lidocaine), and decongestant plus anesthetic (oxymetazoline+lidocaine)...

OBJECTIVES: The current study compared the amount of oxymetazoline delivered by various anesthesia providers when holding the bottle in the upright and inverted position. Additionally, the amount delivered from a full bottle and a half-full bottle was also investigated. METHODS: Using an analytical balance that was calibrated to zero, we evaluated the impact the position of the bottle and the volume of oxymetazoline in the bottle had on the amount being delivered by both anesthesia staff and trainees...

The primary objective of the current investigation was to establish the pharmacokinetic characteristics of oxymetazoline and tetracaine's primary metabolite, para-butylaminobenzoic acid (PBBA), after the intranasal administration of oxymetazoline/tetracaine. Thirty-six subjects contributing a total of 1791 plasma concentration results from 2 open-label trials were utilized. Model development was achieved using data from the second trial (N = 24) in which 0.3 mg oxymetazoline/18 mg tetracaine was administered...

PURPOSE: The compatibility of chemical gingival margin displacement agents with polyether impression materials has not been determined. The aim of this study was to evaluate the setting time of polyether impression elastomers after contact with conventional and experimental gingival displacement agents. MATERIALS AND METHODS: The study compared the setting time of two polyether impression materials: medium body (Impregum Penta Soft) and light body (Impregum Garant L DuoSoft) after contact with 10 gingival displacement agents, including 5 conventional astringents (10%, 20%, and 25% aluminum chloride, 25% aluminum sulfate, and 15...

BACKGROUND: Although nasal steroids are the mainstay treatments in nasal polyposis, up to one-half of patients do not respond and need surgical treatment. This study aimed to evaluate whether oxymetazoline administration produces any additive effect on nasal steroid therapy and whether rebound congestion develops after oxymetazoline treatment. METHODS: Sixty-eight patients with nasal polyposis were randomly assigned in a 1:1 ratio to receive either oxymetazoline plus mometasone furoate nasal spray (MFNS) or placebo plus MFNS, 2 sprays per nostril twice daily, with an interval of 5 minutes between each medication for 4 weeks...

Agnathia-otocephaly or agnathia-sinotia-microstomy syndrome is the most severe malformation affecting the first branchial arch. It is a rare congenital anomaly characterized by absence of the lower jaw and abnormal ear positioning. Prenatal diagnosis is possible on conventional 2-D ultrasound in the second trimester. Three-dimensional ultrasound enhances detection of abnormal facial phenotype, especially in surface rendering mode. In addition, 3-D volume datasets are used to produce a physical model of the anomaly...

MATERIALS AND METHODS: Four human premolars were prepared using air-rotor with air-water spray to receive full crown restoration. Three of them were treated with 21.3% aluminum chloride for 10 min, 0.05% oxymetazoline hydrochloride for 10 min, and expasyl for 2 min, respectively...
