Comparative evaluation of rapidity of action of benzydamine hydrochloride 0.3% oromucosal spray and benzydamine hydrochloride 3 mg lozenges in patients with acute sore throat: A phase IV randomized trial.

ABSTRACT:

Background

Acute sore throat (ST) can occur as part of a common cold of viral origin or caused by pharyngeal bacterial pathogens. The majority of patients with acute ST complain of pain on swallowing and dry scratchiness which can have a negative impact on the quality of life (QoL). This study aimed to evaluate the time to pain relief in patients with acute ST, following a single administration of benzydamine hydrochloride (HCl) 0.3% oromucosal spray or benzydamine HCl 3 mg lozenges.

Methods

This multicenter, randomized, active-controlled, open label, parallel-group, international phase IV study was conducted at 12 investigational centers in Poland, Hungary, and Russian Federation. The study population consisted of 363 adult patients with recent onset (≤3 days) of ST and a diagnosis of tonsillopharyngitis. The primary endpoint was to assess the efficacy of benzydamine HCl in ST pain relief at 2 minutes after a single-dose administration. Secondary endpoints included, among others, the assessment of a first perceived ST relief at 1 minute after a single-dose administration of benzydamine HCl spray or lozenge.

Results

Both the spray and lozenges are effective in providing a ST relief starting already at 2 minutes after a single administration, with an effect lasting up to up to 4 hours. Clinical efficacy after 7 days of treatment and a good safety profile were also demonstrated.

Conclusion

Anesthetic and analgesic properties of benzydamine spray and lozenges effectively addressed the patient priority of a rapid relief of symptoms of upper respiratory tract infections (URTI).

Project description:BackgroundLozenges containing lidocaine and cetylpyridinium chloride (CPC) are commonly used for the treatment of sore throat. The lidocaine acts locally to provide pain relief and the CPC has an antiseptic effect. Mebucaine CL, a well-established fixed-combination sore throat lozenge, contains 1 mg lidocaine and 2 mg CPC. Single-agent lozenges containing 8 mg lidocaine have also been demonstrated to be significantly superior to placebo in confirmatory pain intensity assessments. This study compared a new lozenge formulation, containing 8 mg lidocaine and 2 mg CPC, with the currently marketed lozenge for the treatment and relief of sore throat symptoms in subjects diagnosed with a sore throat due to an upper respiratory tract infection (URTI).MethodsIn this double-blind parallel-group study, 250 adults with a sore throat due to an URTI were randomized to receive a single lozenge containing either 8 mg lidocaine + 2 mg CPC (n = 125) or 1 mg lidocaine + 2 mg CPC (n = 125). The primary efficacy endpoint of the study was the change in sore throat pain intensity (STPI) between baseline (immediately pre-treatment) and the 2-h post-dose assessment, measured on a 100 mm visual analog scale. STPI was measured at baseline and regular intervals up to 240 min after the lozenge was administered (evaluated in clinic). Any difficulty in swallowing and time to onset and duration of the analgesic effect were also assessed.ResultsNo increase in efficacy was demonstrated with the higher dose of lidocaine. The difference in the 2-h post-dose change in STPI was not statistically significant between the treatments. There was only one statistically significant difference between the treatments in all of the efficacy outcomes assessed: pain relief scores at 4 h post-dose were higher with 1 mg lidocaine + 2 mg CPC than with 8 mg lidocaine + 2 mg CPC (P = 0.0461). The most commonly reported adverse event (AE) was a headache; the only other AE experienced by more than one subject was throat irritation. No severe adverse events were reported during the assessment period.ConclusionsThe modest difference in the pattern of effectiveness between the two treatments observed in this study does not support use of the 8 mg lidocaine + 2 mg CPC lozenge.Trial registrationClinicalTrials.gov, NCT01265446 .

Project description:BackgroundBenzydamine for oromucosal use is indicated in the relief of pain and irritation of the mouth and throat. It is an indazole derivative, non-steroidal anti-inflammatory drug, with combined local anesthetic and analgesic properties, and antiseptic activity, marketed under the brand name "Tantum Verde". The aim of this study was to explore knowledge and prescriptive/advising attitudes among general practitioners (GPs) and pharmacists (PHs) with regard to the topical treatment of sore throat and other irritative/inflammatory conditions of the oropharynx, with a focus on benzydamine. These findings could be important to increase awareness on benzydamine efficacy in sore throat and stomatological conditions, and to reinforce knowledge on the characteristics of benzydamine and its mechanisms of action among healthcare professionals (pediatricians, otolaryngologists, oncologists, etc.).Materials and methodsAn online questionnaire survey was performed among PHs and GPs in four European countries (Italy, Germany, Russia and Poland).ResultsBoth GPs and PHs proved to have an excellent knowledge and mastery of the constituents effective against oral symptoms. Among all the principles, benzydamine hydrochloride is the most recognized as certainly suitable for the topical treatment of sore throat symptoms and various inflammatory/irritative conditions of the oral cavity. It is recommended by about 90% of PHs and prescribed by 80% of GPs, mainly to solve the ailments caused by sore throats and stomatitis, especially for its anti-inflammatory, analgesic and anesthetic characteristics. Also in the pediatric field, benzydamine hydrochloride is recommended: among GPs, a high percentage (about 40%) prescribes it like the remedies based on dichlorobenzyl alcohol-sodium benzoate, which are instead more often recommended by PHs (44% against 37%).ConclusionAlthough the public has a lot of confidence in this treatment, GPs and PHs do not recommend/prescribe benzydamine as a first-line treatment of sore throat and other irritative/inflammatory conditions of the oropharynx. To increase the knowledge of benzydamine among these healthcare professionals, it would be important to emphasize its characteristics and the different irritative/inflammatory conditions of the oropharynx in which it can be used.

Project description:BackgroundAntibiotics are inappropriately prescribed to many people with sore throat. As most cases of sore throat are viral and/or self-limiting, guidelines recommend symptomatic management as first-line treatment. This paper reviews the available clinical evidence for the efficacy and safety of low-dose (8.75 mg) flurbiprofen, locally delivered to the throat for the symptomatic management of pharyngitis/sore throat.MethodA literature search was performed on 27 February 2019 using PubMed. Studies that met the following criteria were included in a narrative review: (1) studies evaluating the effectiveness of flurbiprofen for pharyngitis/sore throat; (2) randomized controlled studies; (3) locally administered formulation of study drug/comparator; and (4) flurbiprofen administered at 8.75 mg dose (single- or multiple-dose administration).ResultsA total of 17 papers were included in the review: 15 publications reporting data from nine unique clinical studies of flurbiprofen for acute pharyngitis, and two reporting studies of flurbiprofen for the prevention of postoperative sore throat (POST). Studies in acute pharyngitis demonstrated that single- and multiple-dose flurbiprofen 8.75 mg, locally administered in lozenge, spray or microgranule form, was well tolerated and provided early onset and long-lasting symptomatic relief from throat pain and soreness, sensation of swollen throat, difficulty swallowing, and other associated symptoms. This included patients with more severe symptoms, patients with confirmed Streptococcus A/C sore throat, and patients taking concomitant antibiotics. In addition, a single preoperative dose of flurbiprofen lozenge was shown to be effective for relieving early POST in patients undergoing general anesthesia.ConclusionLocally administered, low-dose flurbiprofen offers a useful first-line treatment option for symptomatic relief in patients with "uncomplicated" acute pharyngitis/sore throat associated with upper respiratory tract infection, thus potentially helping to reduce unnecessary antibiotic prescribing. It also offers an effective preoperative treatment option for the reduction of early POST severity and incidence.
