RESUMO

BACKGROUND: Allergic rhinitis (AR) has shown an increasing prevalence leading to a considerable medical and social burden. Nasal congestion is the cardinal symptom of AR, and the upper respiratory tract is most affected by this long-lasting ailment. Intranasal corticosteroids alleviate nasal congestion, along with other symptoms of AR, but their effect is not evident immediately. Oxymetazoline has a rapid onset of action, but its use should be limited to 3-5 days. OBJECTIVE: The study aimed to evaluate the safety and effectiveness of the fixed-dose combination nasal spray containing fluticasone furoate and oxymetazoline hydrochloride (FF + OXY) 27.5/50 mcg once daily in patients with AR in a real-world clinical setting. METHODS: The study was a prospective, open-label, single-arm, multicenter, real-world observational study conducted in patients with AR for a period of 28 days. Patients (n = 388) with a diagnosis of AR were treated with a combination of FF + OXY nasal spray. Total nasal symptom score (TNSS), total ocular symptom score (TOSS) and total symptom score (TSS) were documented at baseline and at the end of study period. The overall effectiveness of treatment with FF + OXY was rated by the investigators as very good/good/satisfactory/poor (4-point Likert scale) for each patient. RESULTS: Treatment with FF + OXY resulted in significant reduction in the TNSS, TOSS and TSS, from 7.18 ± 3.38 at baseline to 0.20 ± 0.84 (p < 0.001), from 2.34 ± 2.29 at baseline to 0.09 ± 0.53 (p < 0.001), from 9.51 ± 4.94 at baseline to 0.29 ± 1.32 (p < 0.001) at 28 days respectively. With respect to effectiveness, the investigators reported very good effectiveness in 52.12% of patients. No serious adverse events were reported. CONCLUSION: The fixed-dose combination of once-daily fluticasone furoate and oxymetazoline hydrochloride nasal spray 27.5/50 mcg was effective in relieving the nasal congestion and reduction of TNSS, TOSS and TSS in patients suffering from AR. The combination was safe and well tolerated with no rebound congestion throughout the treatment period.

RESUMO

A 72-year-old female with epiphora presented for outpatient punctoplasty with probing and lacrimal stent placement. Oxymetazoline was administered intranasally and the case was completed in standard fashion. Postoperatively, the patient desaturated with a workup revealing elevated cardiac enzymes, pulmonary congestion, and sinus bradycardia. However, the final cardiac testing was noncontributory, suggesting flash pulmonary edema secondary to intranasal oxymetazoline. This case highlights a rare presentation of pulmonary compromise secondary to oxymetazoline, emphasizing the importance of intraoperative and postoperative vigilance in simple outpatient procedures.

RESUMO

BACKGROUND: Since there is currently no conclusion on the efficacy and adverse effects of oxymetazoline, this meta-analysis attempts to explore its efficacy and adverse events, so as to provide guidance for clinical medication. METHODS: We searched PubMed, Embase, and Cochrane Library from the establishment of the database to May 2021. We included studies that patients were randomly assigned to receive oxymetazoline or vehicle, and we excluded duplicate publications, research without full text, incomplete information or inability to conduct data extraction, animal experiments, reviews, and systematic reviews. STATA 15.1 was used to analyze the data. RESULTS: The pooled results show that the 3 (RR = 1.76, 95% CI: 1.53-2.03), 6 (RR = 1.71, 95% CI: 1.47-2.00), 9 (RR = 1.63, 95% CI: 1.40-1.90), 12 (RR = 1.41, 95% CI: 1.18-1.67) -hours CEA success rate and the 3 (RR = 1.65, 95% CI: 1.34-2.03), 6 (RR = 1.75, 95% CI: 1.43-2.14), 9 (RR = 1.63, 95% CI: 1.33-2.00), 12 (RR = 1.78, 95% CI: 1.45-2.18) -hours SSA success rate after oxymetazoline treatment for rosacea is significantly higher than that of vehicle. Additionally, the pooled results show that the incidence of TEAEs after treatment with oxymetazoline is significantly higher than that of vehicle (RR = 1.34, 95% CI: 1.10-1.2). However, our analysis of specific adverse events found that the oxymetazoline group was only significantly higher than the vehicle group in the incidence of application-site dermatitis (RR = 8.91, 95% CI: 1.76-45.23), and there was no statistical significance in the difference in the incidence of other adverse events. CONCLUSION: Oxymetazoline is effective and can be selected for the treatment of persistent facial erythema of rosacea. Additionally, application-site dermatitis was the most important one.

RESUMO

BACKGROUND: Eyelid ptosis following periocular onabotulinumtoxinA (BoNT-A) treatment is a known complication that can be frustrating for both patients and practitioners. Iatrogenic blepharoptosis occurs due to local spread of the BoNT-A from the periocular region into the levator palpebrae superioris muscle. Although injectors should have a thorough understanding of the relevant anatomy in order to prevent it, BoNT-A induced ptosis can occur even in the most experienced hands. OBJECTIVES: The aim of this study was to describe a case series of patients treated effectively with topical oxymetazoline HCl 0.1% and pretarsal BoNT-A injections in the setting of botox-induced ptosis. METHODS: The study group consisted of 8 patients who had undergone recent cosmetic BoNT-A treatment preceding the sudden onset of unilateral upper eyelid ptosis. RESULTS: A diagnosis of severe ptosis (>3 mm) was made in all the cases in this series. Pretarsal BoNT-A injections alone or in association with topical administration of Upneeq eyedrops (Upneeq, Osmotica Pharmaceuticals, Marietta, GA) significantly reversed the ptosis in all treated cases. CONCLUSIONS: This is the first documented case series of patients treated effectively with topical oxymetazoline HCl 0.1% and pretarsal BoNT-A injections in the setting of botox-induced ptosis. This treatment combination is a safe and effective option in these cases.

RESUMO

Post-acne erythema (PAE) is one of the most common sequelae of acne inflammation. Unfortunately, the treatment of PAE remains challenging due to limited effective topical treatments. The objectives of this study were to evaluate the efficacy and safety of topical oxymetazoline hydrochloride (OxH) 0.05% solution for PAE. This study was a split-face, participants-and investigators-blinded, randomized, placebo-controlled trial conducted between December 2021 and March 2022 in Bangkok, Thailand. Healthy adults aged from 18 to 45 years with mild to severe PAE, according to the Clinician's Erythema Assessment (CEA), on both sides of the face were eligible. After randomization, each participant applied the OxH to one side of their face and a placebo to the contralateral face twice daily for 12 weeks. The primary outcome was PAE lesion counts. The secondary outcomes were erythema index, clinical response rate at week 12 ("clear," "almost clear," or "at least two-grade improvement" by CEA), and patient satisfaction scores. A total of 30 participants were enrolled. The OxH-treated skin showed a significantly greater mean difference (MD) reduction in PAE lesion counts than the placebo after 8 weeks of treatment (4.30, 95% confidence interval [CI] 1.42-7.18). Similarly, the MD reduction of the erythema index was higher in the OxH-treated skin from the second week (11.82, 95% CI 8.48-15.15). Additionally, the OxH-treated side also achieved a higher clinical response rate after 8 weeks of treatment (40.00% vs. 6.67%; p = 0.002) and rated higher satisfaction than those using the placebo at the end of the study (mean [standard deviation] satisfaction score 8.30 [0.18] vs 7.40 [0.18], P < 0.001). There were no serious adverse events or flares of erythema during the study. In conclusion, our study demonstrated that the topical OxH 0.05% solution was effective, well-tolerated, and safe for reducing PAE without a rebound effect. It could be a choice of PAE management.

RESUMO

BACKGROUND: Facial persistent erythema is recognized as difficult feature to treat in rosacea. Topical Oxymetazoline cream 1% has been used to treat persistent facial erythema in rosacea patients for some years. OBJECTIVE: To quantitatively synthesize the benefits and harms of Oxymetazoline cream 1% in real-world clinical management of treatment response and adverse events. METHODS: The clinical researches before June 1, 2022 published on online databases including PubMed, Web of Science, Embase and Cochrane Library were meta-analyzed. RESULTS: A total of 2298 participants were included, and the improvement rate of two-grade Clinician Erythema Assessment score (CEA) and Subject Self-Assessment for rosacea facial redness score (SSA) in Oxymetazoline group was 38% (95%CI 28-48) and 25% (95%CI 22-27), respectively, at the 4th week of the dosing. The comprehensive rate of treatment-related TEAEs in Oxymetazoline group was 7% (95%CI 5-8). The rate of stinging/burning was 15% (95%CI 10-19), pruritus was 15% (95%CI 9-22), dryness was 23% (95%CI 18-28), and scaling was 17% (95%CI 12-22) in analysis of dermal tolerability. And topical Oxymetazoline cream 1.0% presented a very low rebound rate of erythema (1%, 95%CI 0-2). CONCLUSIONS: These real-world data on Oxymetazoline cream 1% in rosacea-associated erythema may help making clinic decision and informing treatment expectations, and more clinic trials on longer-term dosing or the combination treatment with oral medication and energy-based therapy are worth exploring.

RESUMO

OBJECTIVE: To assess for differences in postoperative otorrhea rates after tympanostomy with tube placement surgery comparing use of oxymetazoline, ofloxacin, or ciprofloxacin/dexamethasone drops prescribed in the postoperative period. METHODS: A retrospective review was conducted of 516 pediatric patients who had either bilateral or unilateral myringotomy with tube placement performed during the year 2018. Information collected from each surgery included whether there was effusion at time of surgery, type of effusion, whether an adenoidectomy was performed the same time or prior, prior history of tube placement, style of tube placed, type of drop given or prescribed on the day of surgery. Demographic information including age, sex, race, weight was recorded as well. Finally, the postoperative visit was analyzed for presence of otorrhea in the ears that had surgery. Univariate analysis was conducted to see if there was any association between the three different drops and presence of otorrhea postoperatively. RESULTS: Postoperative otorrhea was present in 50 of the 516 patients (9.7 %). We observed no significant difference between the type of drop used and postoperative otorrhea being present (p = 0.179), but prior placement of tubes was significantly correlated to postoperative otorrhea (p < 0.001). There was no relationship between type of tube used, prior tube placement, or history of adenoidectomy with type of ear drop used. CONCLUSION: Overall, there is no significant difference in the rate of postoperative otorrhea when choosing between oxymetazoline, ofloxacin, or ciprofloxacin/dexamethasone drops for use in the postoperative period after tympanostomy tube placement.

RESUMO

OBJECTIVES: Topical intranasal decongestants are essential in nasal surgery to improve operative field. There are concerns regarding safety in paediatric population. Data on safety and safe dosage are limited. This systematic review evaluated the literature on safety and dosage of intranasal decongestant in paediatric population. METHODS: We performed a systematic search of PubMed, EMBASE, Cochrane library for relevant articles. Quality assessment was done on included articles. RESULTS: A total of 10 articles were included: five case reports; three observational studies; and two randomised control trials. Decongestants evaluated were phenylephrine, oxymetazoline, epinephrine, xylometazoline, and cocaine. In total, 209 patients were included. Side effects reported included bradycardia, tachycardia and hypertension. These were mostly self-limiting and of no clinical compromise to the patients. A total of 4/209 (1.9%) of patients required treatment for these reported effects. No mortality was reported in the included studies. CONCLUSION: In the paediatric population, the literature suggests that when delivered in a pre-specified, controlled dosage, the haemodynamic effects of phenylephrine, oxymetazoline, xylometazoline are minimal and of no clinical significance. There is scope for further studies to establish safe dosage in the paediatric population given the paucity of current literature.

RESUMO

BACKGROUND: Post-inflammatory erythema (PIE) is a common sequalae of acne inflammation, persistent post acne erythema (PAE) is cosmetically unacceptable and sometimes its complete clearance could not be achieved. Oxymetazoline (OXZ) is a synthetic, direct-acting, sympathomimetic agonist that is highly selective for the 1α-adrenoceptor. It is a potent vasoconstrictor and well known for its ability to clinically 'get the red out'. AIM: The aim of this study was to evaluate the efficacy and safety of topical oxymetazoline (OXZ) 1.5% in treatment of post acne erythema (PAE) in a left to right face comparative study. METHODS: This study was conducted on 40 patients diagnosed with post acne erythema for at least 3 months, the left side of the face was treated with topical OXZ 1.5% in liposomal base and was compared to the right side to which topical lipogel was applied as a control. RESULTS: According to the investigator's global assessment of photographs and the analysis of erythema with image analysis software, topical OXZ was significantly effective in diminishing PAE when compared to topical placebo lipogel. CONCLUSION: Topical OXZ is a safe and effective treatment for post-acne erythema.

RESUMO

The over-the-counter nasal decongestant oxymetazoline (eg, Afrin) is used in the pediatric population for a variety of conditions in the operating room setting. Given its vasoconstrictive properties, it can have cardiovascular adverse effects when systemically absorbed. There have been several reports of cardiac and respiratory complications related to use of oxymetazoline in the pediatric population. Current US Food and Drug Administration approval for oxymetazoline is for patients ≥6 years of age, but medical professionals may elect to use it short-term and off label for younger children in particular clinical scenarios in which the potential benefit may outweigh risks (eg, active bleeding, acute respiratory distress from nasal obstruction, acute complicated sinusitis, improved surgical visualization, nasal decongestion for scope examination, other conditions, etc). To date, there have not been adequate pediatric pharmacokinetic studies of oxymetazoline, so caution should be exercised with both the quantity of dosing and the technique of administration. In the urgent care setting, emergency department, or inpatient setting, to avoid excessive administration of the medication, medical professionals should use the spray bottle in an upright position with the child upright. In addition, in the operating room setting, both monitoring the quantity used and effective communication between the surgeon and anesthesia team are important. Further studies are needed to understand the systemic absorption and effects in children in both nonsurgical and surgical nasal use of oxymetazoline.

RESUMO

OBJECTIVE: Topical oxymetazoline and brimonidine are the only medications approved for treating persistent facial erythema of rosacea. This review aims to investigate the efficacy, safety, pharmacodynamics, and pharmacokinetic properties of oxymetazoline and brimonidine. METHODS AND MATERIALS: Phase II and phase III clinical studies evaluating oxymetazoline and brimonidine were assessed to compare their efficacy and safety. RESULTS: In their respective phase III trials, both oxymetazoline and brimonidine met the primary efficacy outcome of having at least a 2-grade decrease from baseline on both the Clinician Erythema Assessment (CEA) and the Subject Self-Assessment (SSA) Scales compared to the vehicle control. Treatment related adverse events of oxymetazoline and brimonidine are most often mild and localized. CONCLUSIONS: Topical oxymetazoline and brimonidine are effective for the management of persistent facial erythema associated with rosacea with a few mild and localized adverse effects. Further long-term research is imperative to further understand their long-term effects.

RESUMO

OBJECTIVE: Rhinitis medicamentosa is drug-induced rhinitis which occurs by prolonged and overdose usage of topical nasal decongestants. There is not much of treatment choice rather than nasal steroids. In this pathological study, we have been aimed to represent the healing effects of xylitol on damaged nasal mucosa due to rhinitis medicamentosa. METHOD: 30 Wistar rats were separated into 5 groups. During 2 months, oxymetazoline was given to the first group, and saline was given to second group intranasally. First and second group animals were examined at the end of 2 months and rhinitis medicamentosa was detected. Oxymetazoline was given to the third, fourth, and fifth groups during 2 months. Then xylitol solution, mometasone, and saline were applied, respectively, for 15 days. After the experiment, rats' nasal mucosas were evaluated histopathologically. RESULTS: Xylitol and mometasone were found to be more effective than the control group in terms of histopathological changes. Effectivity of xylitol and mometasone was compared and not a significant value was determined. CONCLUSIONS: According to the results, xylitol solution is effective as mometasone, usable and well-priced in the treatment of rhinitis medicamentosa. More comprehensive and ultrastructural studies on animals and human studies with rhinometric evaluation should be performed.

RESUMO

An unmet need exists for a safe, tolerable, effective treatment for moderate to severe persistent facial erythema in patients with rosacea. This pivotal phase 3, multicenter, double-blind study evaluated the efficacy and safety of topical oxymetazoline in patients with facial erythema associated with moderate to severe rosacea. Patients were randomly assigned to treatment with oxymetazoline hydrochloride cream 1.0% or vehicle applied once daily for 29 days, and were followed for 28 days posttreatment. The primary efficacy outcome was having at least a 2-grade decrease from baseline on both the Clinician Erythema Assessment (CEA) and the Subject Self-Assessment for rosacea facial redness (SSA) scales (composite success) at 3, 6, 9, and 12 hours postdose on day 29. Safety assessments included treatment-emergent adverse events (TEAEs) and posttreatment worsening of erythema (composite CEA/SSA increase of 1-grade severity from baseline; rebound effect). A total of 440 patients (mean age, 49.5 years; 78.9% females) were randomized (oxymetazoline, n=222; vehicle, n=218); most had moderate erythema. On day 29, significantly greater proportions of oxymetazoline recipients achieved the primary efficacy outcome at each time point (P less than 0.02) and overall (P less than 0.001) compared with vehicle recipients. The incidence of discontinuation due to TEAEs was low in both groups (oxymetazoline group, 1.8%; vehicle group, 0.5%). The most common TEAEs reported during the entire study period were application-site dermatitis, application-site erythema, and headache in the oxymetazoline group (1.4% each), and headache (0.9%) in the vehicle group. Following cessation of treatment, low proportions of patients experienced rebound effect (oxymetazoline group, 2.2%; vehicle group, 1.1%). Oxymetazoline applied to the face once daily for 29 days was effective, safe, and well tolerated in patients with moderate to severe persistent facial erythema of rosacea.

RESUMO

BACKGROUND: Topical α-adrenergic agonist therapy has been developed to treat the persistent erythema of rosacea patients. Brimonidine and oxymetazoline are both topical α-adrenergic agonists. OBJECTIVES: The objective of this in vitro safety pharmacology study was to compare the potential safety profiles of brimonidine and oxymetazoline. METHODS: Brimonidine and oxymetazoline underwent pharmacological profiling with a standard panel of 151 assays, including α-adrenergic receptors and 5-hydroxytryptamine (5-HT) receptors. A valvular interstitial cell (VIC) proliferation assay was performed with oxymetazoline hydrochloride. RESULTS: Brimonidine was highly selective for the α2 adrenergic receptors, specifically α2A, whereas oxymetazoline was found to be much less selective and was highly active against a wide range of targets. Negligible activity was observed with brimonidine at the 5-HT2B receptor, whereas oxymetazoline had significant 5-HT2B receptor agonist activity and caused proliferation of mitral VICs in vitro. CONCLUSION: As the 5-HT2B receptor is potentially involved in drug-induced valvulopathy, the benefit/risk ratio should be carefully considered, especially in patients with cardiovascular disease or other comorbidities.

RESUMO

OBJECTIVE: To review and summarize topical oxymetazoline's pharmacology, pharmacokinetics, efficacy, safety, cost, and place in therapy for persistent redness associated with erythematotelangiectatic rosacea. DATA SOURCES: Literature searches of MEDLINE (1975 to September 2017), International Pharmaceutical Abstracts (1975 to September 2017), and Cochrane Database (publications through September 2017) using the terms rosacea, persistent redness, α -agonist, and oxymetazoline. STUDY SELECTION AND DATA EXTRACTION: Results were limited to studies of human subjects, English-language publications, and topical use of oxymetazoline. Relevant materials from government sources, industry, and reviews were also included. DATA SYNTHESIS: Data support the efficacy of oxymetazoline for persistent facial redness. Little study beyond clinical trials cited in the drug approval process has been conducted. Current data suggest that oxymetazoline is similar in safety and efficacy to brimonidine. Head-to-head comparisons of topical α-agonists for erythema caused by rosacea are needed. CONCLUSION: The topical α-agonist, oxymetazoline, is safe and effective for reducing persistent facial redness associated with erythematotelangiectatic subtype of rosacea. Health care practitioners selecting among treatments should consider not only the subtype of rosacea but also individual patient response, preference, and cost.

RESUMO

INTRODUCTION: Rosacea is a chronic skin condition characterized by transient and persistent erythema of the central face. The symptom of persistent erythema can be particularly frustrating for both patients and physicians as it is difficult to treat. Areas covered: Current treatment options for the treatment of rosacea include metronidazole, azelaic acid, sodium sulfacetamide-sulfur, and brimonidine. Until recently, brimonidine gel was the only option approved specifically for the treatment of facial erythema. However, oxymetazoline hydrochloride 1% cream is a newly FDA approved topical medication for adult rosacea patients. A primarily alpha-1a agonist, oxymetazoline hydrochloride (HCl) is thought to diminish erythema through vasoconstriction. Our paper seeks to evaluate evidence for topical oxymetazoline HCl with respect to its efficacy and safety for its approved indication of treating the persistent erythema associated with rosacea. Expert commentary: While assessment of available clinical trial data indicates that the medication is as effective as other available treatment for controlling rosacea-associated erythema with minimal risk of adverse effects, studies of long-term duration and direct comparison will be necessary to establish its place in treatment guidelines and clinical practice. As further evidence becomes available, the real-world clinical potential of topical oxymetazoline cream will become clearer.
