This was a randomized, double-blind vehicle controlled study aimed at investigating the effects on nasal function of 7 days treatment with the topical decongestant oxymetazoline (0.05% w/v). Fifty healthy volunteers took part in the study and these were randomly allocated to three treatment groups (i) daily oxymetazoline (b.i.d. 150 μl per nostril) (ii) intermittent oxymetazoline, with oxymetazoline being substituted for vehicle at the morning doses on days 1, 3, and 7; and (iii) daily vehicle (b.i.d. 150 μl per nostril). The nasal airway was assessed by measurement of nasal airway resistance (NAR) using posterior rhinomanometry, subjective scaling of nasal patency by means of a visual analogue scale (VAS), and clinical visual examination. On days 1, 2, 3, and 7, NAR and VAS measurements were obtained before the morning dose and up to 6 hours after dosing; clinical visual examinations were also performed before dosing on these days. NAR and VAS measurements were also made following withdrawal of treatment on Days 8 and 9. Nonparametric analysis of the results showed that therapeutic tolerance to oxymetazoline did not develop over the 7-day treatment period, and visual examination of the nasal mucosa failed to find significant evidence of rhinitis. Evidence of rebound nasal congestion was found following 3 days of oxymetazoline treatment, with baseline NAR within the daily and intermittent oxymetazoline groups being significantly greater on Day 3 compared to Day 1 (p < 0.05). However, there was a trend toward increasing baseline NAR in the vehicle group over the course of the study, suggesting that the vehicle may have contributed to the rebound congestion. Following the withdrawal of treatments, only the intermittent oxymetazoline group had significantly higher NAR on Days 8 and 9 compared to Day 1 (p < 0.05). Subjective VAS measurements generally followed trends in NAR.

Introduction. Antihistamines are the most commonly prescribed class of medications for the treatment of allergic rhinitis (AR). However, they are also widely used in the treatment of inflammatory diseases of the ENT organs. One such drug is levocytirizine, (R) an enantiomer of cetirizine, which is a selective antagonist of peripheral histamine H1-receptors. This article analyzes the properties of levocytirizine in terms of safety and efficacy in allergic rhinitis.Aim of the study is to assess the efficacy of levocetirizine in patients with seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR) versus placebo, and safety for patients with allergic rhinitis.Materials and methods. In this, double-blind, placebo-controlled study, 52 patients with year-round allergic rhinitis and 28 patients with seasonal allergic rhinitis were randomized to receive levocetirizine 5 mg/day once or placebo. Mean overall measures of five symptoms (nasal congestion, nasal itching, itchy eyes, rhinorrhea, and sneezing) were compared between treatment groups at 1, 2, and 4 weeks. All individual symptom scores were also examined.Results. Levocetirizine showed a significant improvement in the condition of patients with CAR and SAR over the entire treatment period compared to placebo. Assessment of individual symptoms showed statistically significant differences in favor of levocetirizine. Conclusion. Levocetirizine is an effective, safe, and well-tolerated drug for the treatment of allergic rhinitis.

Objective: Vardenafil has been shown to be efficacious in patients with erectile dysfunction (ED). We evaluated first-dose and repeat-dose response to vardenafil 20 mg.Methods: This randomized, placebo-controlled study consisted of a 4-week, treatment-free run-in phase; a 1-week, open-label challenge phase; and a 12-week, double-blind treatment phase. Primary efficacy was assessed in terms of reliability of insertion based on dose as measured by the Sexual Encounter Profile question 2 (SEP2). We assessed safety by evaluating adverse events (AEs).Results: Baseline patient characteristics in the 2 treatment groups were similar. The most common comorbidities were hypertension (41%), dyslipidemia (28%) and diabetes mellitus (24%). Of the 573 patients receiving the 20-mg vardenafil challenge dose, 464 (81%) achieved first-time successful penetration (SEP2), and 401 (70%) reported successful erection maintenance (SEP3). Patients receiving vardenafil 20 mg had statistically (p < 0.001) and clinically superior SEP2 rates (85%) through weeks 0–12, compared with patients receiving placebo (45%). The increase in reliability of insertion was seen within the first 4 weeks of treatment. Vardenafil therapy was statistically (p < 0.001) and clinically superior to placebo for all secondary efficacy end points as well. Most AEs associated with vardenafil were mild to moderate, with headache, flushing and nasal congestion most frequently reported.Conclusion: Vardenafil 20 mg had a high first-dose success rate for both SEP2 (81%) and SEP3 (70%); this was maintained through to the study end point (85% for SEP2 and 78% for SEP3). These findings were achieved in men with frequentlyassociated comorbidities including hypertension, dyslipidemia and diabetes.

ABSTRACT Oral valacyclovir is better absorbed than oral acyclovir, increasing acyclovir bioavailability three- to fivefold. This provides the opportunity to explore whether high systemic acyclovir concentrations are effective in the treatment of cold sores (herpes labialis). Two randomized, double-blind, placebo-controlled studies were conducted. Subjects were provided with 2 g of valacyclovir twice daily for 1 day (1-day treatment), 2 g of valacyclovir twice daily for 1 day and then 1 g of valacyclovir twice daily for 1 day (2-day treatment), or a matching placebo and instructed to initiate treatment upon the first symptoms of a cold sore. In study 1, the median duration of the episode (primary endpoint) was reduced by 1.0 day (P = 0.001) with 1-day treatment and 0.5 days (P = 0.009) with 2-day treatment compared to placebo. Similarly, the mean duration of the episode was statistically significantly reduced by 1.1 days with 1-day treatment and 0.7 days with 2-day treatment compared to placebo. The proportion of subjects in whom cold sore lesion development was prevented and/or blocked was increased by 6.4% (P = 0.096) with 1-day treatment and 8.5% (P = 0.061) with 2-day treatment compared to placebo. The time to lesion healing and time to cessation of pain and/or discomfort were statistically significantly reduced with valacyclovir compared to placebo. In study 2, results similar to those in study 1 were obtained. AEs were similar across treatment groups. These studies provide evidence supporting a simple, 1-day valacyclovir treatment regimen for cold sores that is safe and effective. The 1-day valacyclovir regimen offers patients a unique and convenient dosing alternative compared to available topical therapies.

Objective. Circumcision is a common neonatal surgical procedure routinely performed without the use of anesthesia. The purpose of this study was to evaluate the safety and efficacy of topical lidocaine cream as an anesthetic for circumcision. Methods. Thirty newborns were studied in a randomized, double-blind, placebo-controlled study; 15 received a topical 30% lidocaine cream and 15 received the cream base alone. Vital signs were recorded, and preoperative and postoperative serum β-endorphin and lidocaine concentrations were measured. A videotape of the newborn was used to score behavioral changes. Results. Comparisions of the vital signs precircumcision and postcircumcision showed no differences between the placebo and treatment groups, with the exception of mean systolic blood pressure, which significantly increased in the placebo-treated newborns (P &lt; .05). Serum β-endorphin concentrations increased postoperatively in 11 of 15 subjects receiving placebo, but decreased or remained unchanged in 10 of 15 subjects receiving lidocaine (P = .03, Fisher's exact test). When stress-related behaviors in the precircumcision and post-circumcision periods were compared, the mean increase in their occurrence was greater in the placebo than in the treatment group. There was no significant absorption of lidocaine as measured in the serum. Conclusion. Topical application of a 30% lidocaine cream as used in this study may be a safe and efficacious anesthetic for circumcision.

Abstract Background Epidermolysis bullosa (EB) is a rare genetic disorder that manifests as blistering and/or skin erosion. There is no approved treatment for EB; current standard of care consists of wound and pain management. SD-101 6% is a topical cream containing 6% allantoin that was developed for treating skin lesions in patients with EB. The aim of this phase 3, multicenter, randomized, double-blind, vehicle-controlled study was to assess the efficacy and safety of SD-101 6% cream versus vehicle (0% allantoin) on lesions in patients with EB. Methods Eligible patients were ≥1 month old, had a diagnosis of EB (simplex, recessive dystrophic, or intermediate junctional) and a target wound 10–50 cm2 in size that was present for ≥21 days. Patients were randomly assigned to SD-101 6% cream or vehicle, which was applied topically once a day to the entire body for 3 months. Primary efficacy endpoints were time to complete target wound closure within 3 months and the proportion of patients who experienced complete target wound closure within 3 months. Post hoc subgroup analyses were conducted by patient age and in those with body surface area index of total body wound burden ≥5% at baseline. Results In total, 169 patients were enrolled and randomly assigned to SD-101 6% (n = 82) or vehicle (n = 87). Baseline demographics and disease characteristics were similar between treatment groups. There were no statistically significant differences between treatment groups in time to target wound closure (hazard ratio, 1.004; 95% confidence interval [CI] 0.651, 1.549; P = 0.985) or proportion of patients with complete target wound closure within 3 months (odds ratio [95% CI], 0.733 [0.365, 1.474]; nominal P = 0.390). A positive trend toward faster wound closure with SD-101 6% versus vehicle was observed in patients aged 2 to <12 years and those with total body wound burden ≥5% at baseline. SD-101 6% cream was well tolerated. Conclusions SD-101 6% cream for treatment of EB-associated lesions was not more effective than vehicle in shortening the time to complete target wound closure or achieving complete target wound closure within 3 months.

BackgroundThis study compared the efficacy and tolerability of paroxetine with placebo in the treatment of panic disorder.MethodAfter three weeks of placebo, patients received 12 weeks of treatment with paroxetine (20, 40, or 60 mg) or placebo, and finally two weeks of placebo. Dosages were adjusted according to efficacy and tolerability. Standardised cognitive therapy was given to all patients. The primary measure of outcome was reduction in the number of panic attacks.ResultsAnalysis of the results showed statistically significant differences in favour of paroxetine between the two treatment groups in two out of the three primary measures of outcome, i.e. 50% reduction in total number of panic attacks and number of panic attacks reduced to one or zero over the study period. For the third measure of outcome, the mean change in the total number of attacks from baseline, there was a positive trend in favour of paroxetine. The results of the primary measures of outcome were strongly supported by the results of the secondary efficacy measures of outcome. In addition, paroxetine, at all doses, was very well tolerated.ConclusionParoxetine plus cognitive therapy was significantly more effective than placebo plus cognitive therapy in the treatment of panic disorder.

Background This study evaluated the efficacy of montelukast in reducing seasonal allergic rhinitis symptoms in Japanese children with Japanese cedar (JC) pollinosis induced in an artificial exposure chamber (OHIO Chamber). Methods Pediatric patients aged 10 to 15 years sensitive to JC pollen entered a randomized, double-blind, single-site, crossover study. After confirmation of an allergic response to a JC pollen exposure for 3 hours in the OHIO Chamber during the screening period, subjects received either montelukast 5 mg chewable tablets or placebo for a 7-day treatment period, followed by a 3-hour pollen exposure in the chamber. After a 7-day washout period, subjects crossed over to the other treatment. Subjects were instructed to self-assess their nasal symptoms using 5-point scale for every 30 minutes. The primary end point was the change from baseline (just before entering the exposure chamber for each exposure) in total nasal symptom score (TNSS; the sum of nasal congestion, nasal discharge, and sneezing scores) over 3 hours of pollen exposure. Adverse events (AEs) were evaluated throughout the study. Results A total of 220 subjects (median age, 12 years) received treatment. For TNSS, the between-group difference in the change (95% confidence interval) was −0.01 (−0.11 to 0.10); the change between placebo and montelukast 5 mg was not significant. TNSS in the screening and treatment periods after receiving placebo for 7 days was 1.58 and 1.31, respectively, suggesting a placebo response. On account of high placebo response, a post hoc analysis was conducted. The analysis in a subgroup of subjects who did not show placebo response demonstrated a difference in the efficacy between montelukast and placebo (nominal P < .037). The most common AE was positive urine protein (4.6% with montelukast vs 7.8% with placebo). Conclusions Although montelukast was well tolerated, this study did not demonstrate a treatment difference between active drug and placebo in Japanese children exposed to JC pollen in the OHIO Chamber.

Objective.This phase I study aimed to systematically assess the safety, local tolerability, pharmacokinetics, and preliminary efficacy of topical icotinib hydrochloride cream in patients with mild to moderate plaque psoriasis.Materials and Methods.Eligible Chinese adult patients with mild to moderate psoriasis were assigned to the icotinib cream or vehicle group. Icotinib cream with increasing concentrations (0.5%, 1.0%, 2.0%, and 4.0%) or vehicle were administered by the fingertip unit method to the skin lesions twice a day for 4 weeks. Safety assessments included the incidence and severity of adverse events (AEs), local tolerability at the treatment area, vital signs, and laboratory examinations. Plasma levels of icotinib were also measured for the pharmacokinetics calculation. The efficacy was preliminarily explored by assessing the improvement in the severity level using Target Plaque Severity Score (TPSS) and overall improvement using the Psoriasis Area Severity Index (PASI) and Dermatological Quality Life Index.Results.Forty-one patients were enrolled and qualified for safety analysis. 27 (65.9%) patients experienced at least one AE, of which application-site adverse drug reactions (ADRs) were reported in 6 (14.6%) patients. All ADRs were of grade 1 or 2, most common irritation (4.5%), itching (3.1%), and erythema (2.4%), and resolved during follow-up. The systemic exposure to icotinib was very low; the highest plasma concentration was 0.214 ng/mL, while the area under the curve from 0 to 12 hours was 1.626 h·ng/mL. The TPSS improved for all icotinib groups after treatment in a dose- and time-dependent manner.Conclusion.This phase 1 study demonstrated favorable safety, tolerable toxicity, and preliminary efficacy of icotinib cream in patients with mild to moderate psoriasis. The dose concentration of 2.0% (twice daily based on the fingertip unit method) is recommended for further study.Study Design.This is a single-center, randomized, double-blind, and vehicle-controlled study.
