Study Description

Brief Summary:

The purpose of the study is to evaluate the local tolerability and the systemic availability of benzydamine, if any, after single and multiple dose treatment with the test formulation containing cetylpyridinium chloride 0.05% + benzydamine hydrochloride 0.15% + mucoadhesive polymer and with the reference formulation Tantum Verde Bocca containing cetylpyridinium chloride 0.05% + benzydamine hydrochloride 0.15% to healthy subjects , under fasting conditions, in two consecutive study periods.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Test product CTP/BNZ with mucus adhesive polymer; A multiple dose of the Cetylpyridinium Chloride 0.05%+Benzydamine HCl 0.15% (CTP/BNZ) + mucus adhesive polymer is administered to healthy subjects twice a day for 7 days, under fasting conditions in two subsequent periods according to the randomised cross-over design.	Drug: Cetylpyridinium Chloride 0.05% + Benzydamine HCl 0.15% + mucus adhesive polymer; Test product will be applied twice a day (b.i.d) every 12 h once in the morning and once in the evening for 6 consecutive days (from Day 1 to Day 6) and once in the morning on Day 7 for a total of 13 dose
Active Comparator: Reference product CTP/BNZ - Tantum Verde Bocca; A multiple dose of the Cetylpyridinium Chloride 0.05%+Benzydamine HCl 0.15% (CTP/BNZ) Tantum Verde Bocca is administered to healthy subjects twice a day for 7 days, under fasting conditions in two subsequent periods according to the randomised cross-over design.	Drug: Cetylpyridinium Chloride 0.05% + Benzydamine HCl 0.15%; Reference Product will be applied twice a day (b.i.d) every 12 h once in the morning and once in the evening for 6 consecutive days (from Day 1 to Day 6) and once in the morning on Day 7 for a total of 13 dose; Other Name: Tantum verde bocca

Outcome Measures

Primary Outcome Measures :

1. Change in Local Adverse Reactions (ADRs) [ Time Frame: Change before and after each administration up to Day 8 ]
   Local ADRs reported by the subjects through a 4-point scale according to a local tolerability scale (degree of severity of reactions from 0 to 3. 0=none; 1=mild 2= moderate; 3= severe) as 0-3 scores for burning sensation, irritation, pruritus, dry mouth, salivary hypersecretion and dysphagia. If the score assigned will be 1, 2 or 3, the local AE will classified as a TEAE of mild, moderate or severe severity, respectively.

Secondary Outcome Measures :

1. Systemic availability of benzydamine (free base) through Cmax. [ Time Frame: Day 1: pre-dose, 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 12 h after the first dose. Days 7-8: pre-dose, 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 12, 16, 24 h after the last dose. ]
   Systemic availability of benzydamine (free base) by measurement of plasma concentrations.
2. Systemic availability of benzydamine (free base) through AUC(0-t). [ Time Frame: Day 1: pre-dose, 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 12 h after the first dose. Days 7-8: pre-dose, 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 12, 16, 24 h after the last dose. ]
   Systemic availability of benzydamine (free base) by measurement of area under the plasma concentration-time curve [AUC(0-t)].
3. Incidence of AEs [ Time Frame: Through study completion, an average of three weeks ]
   General tolerability and safety of the study products assessed through monitoring of AEs including clinically significant abnormalities in laboratory assays (haematology, blood chemistry, urinalysis).
4. Palatability [ Time Frame: Day 7 (after the last dose of each study period). ]
   Organoleptic properties of the study products evaluated through a ORGANOLEPTIC AND EASE OF USE CHARACTERISTICS questionnaire.
