Brief Summary

The goal of this clinical trial is to examine the effectiveness of intranasal-administered Chlorpheniramine Maleate in COVID-19-positive participants as part of early treatment for COVID-19. The main questions it aims to answer are:

* To assess the efficacy of nasal spray with Chlorpheniramine (0.4%) for improving clinical recovery in COVID-19 patients.

* To assess the efficacy, safety, and tolerability of nasal spray with Chlorpheniramine (0.4%) as an adjunct to the standard of care in reducing hospitalizations and improving clinical recovery in adult patients with mild COVID-19.

Detailed Description

The main goal of the present study is to examine the effectiveness of CPM intranasal spray as part of early treatment for COVID-19. The study will test the hypothesis that intranasal CPM would accelerate clinical recovery, particularly the alleviation of sensory symptoms and URS, in patients with COVID-19.

Primary Outcome Measures
NameTimeMethod
Visual Analog Scale (VAS)Baseline through day 7

Change from baseline visual analog scale (VAS) to day 7

The VAS is a quantitative method that evaluates the severity of symptoms on a scale of 1-10 (no signs to worst symptoms). A 10 cm line is used to grade the severity of symptoms from "no symptoms" (0 cm) to "the highest level of symptoms" (10 cm).

Daily symptoms score (DSS)Baseline through day 7

Change from baseline daily symptoms score (DSS) to day 7

The DSS is an instrument comprised of a four-point severity rating scale ranging from 0 to 3.

0 = no symptoms

1. = mild symptoms

2. = moderate symptoms

3. = severe symptoms.

Secondary Outcome Measures
NameTimeMethod
HospitalizationBaseline through Day 28

The proportion of Hospitalizations

MortalityBaseline through Day 28

Rate of mortality

The proportion of subjects reporting olfactory functionBaseline through Day 7

Olfactory function reported on a four-point severity rating scale ranging from 0 to 3.

0-normal

1. slightly damaged

2. moderately damaged

3. away

The proportion of subjects reporting the presence of upper respiratory symptomsBaseline through Day 7

The proportion of subjects reporting the presence of upper respiratory symptoms (anosmia, ageusia, cough, and nasal congestion) using a yes or no scale.

Yes- Present No- No symptoms present
