Efficacy of Nasal Naphazoline Hydrocloride + Pheniramine Maleate + Panthenol Compared With Naphazoline Hydrocloride in the Symptomatic Control of Nasal Congestion and Nasopharyngeal

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

The common cold is a major cause of nasal obstruction and reaches children and adults twice or more times a year. At the moment, there is no cure for the common cold, and therefore the reduction of symptoms is the focus of treatment.

The study was designed to parallel distribution, with two equal groups, with one group will receive treatment with a combination of naphazoline hydrocloride + pheniramine maleate + panthenol and the other will receive treatment with naphazoline hydrocloride.

Condition Intervention Phase
Flu Cold Allergic Disorder of Respiratory System Drug: naphazoline hydrocloride Drug: Naphazoline hydrocloride + Pheniramine Maleate + Panthenol Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Double-blind, Prospective, Monocentric, Superior Efficacy and Safety of Naphazoline Hydrocloride + Pheniramine Maleate + Panthenol Compared With Naphazoline Hydrocloride in the Symptomatic Control of Nasal Congestion and Nasopharyngeal Due to Colds or Other Upper Respiratory Allergies

Further study details as provided by EMS:

Primary Outcome Measures:
  • Efficacy of treatment in nasal congestion reduction based on Peak Flow Nasal Inspiratory (PFNI) assay [ Time Frame: Day 5 ]

    The individual response rate to the nasal congestion reduction is calculated by measuring the peak flow nasal inspiratory (PFNI) during the first and last visit.

    The response rate is calculated using the following formula:

    Response rate = (PFNIvi - PFNIvf) / PFNIvi


    • PFNIvi: PFNI in the first visit;
    • PFNIvf: PFNI at the last visit;

Secondary Outcome Measures:
  • Safety will be evaluated by the Adverse events occurence [ Time Frame: Day 5 ]
    Adverse events will be collected and followed in order to evaluate safety and tolerability

Estimated Enrollment: 212
