Active clinical trials for "Common Cold"

National clinical trial, phase III, multicenter, randomized, prospective, double-blind, parallel, placebo-controlled, which one hundred and fifty (150) subjects of both sexes aged equal or more than 18 years will be randomly allocated to one the drug group or placebo group.

This will be a randomized, double-blind, placebo controlled, parallel-group Phase 2 study to evaluate the efficacy of a new formulation of phenylephrine HCl and a currently marketed phenylephrine HCl for relief of nasal congestion in subjects with naturally occurring cold symptoms.

Nasal glucocorticosteroids (GCS) are considered first-line therapy for both allergic and non-allergic rhinitis.1-3 Nasal congestion can persist despite maximum treatment with intranasal GCS. No other drugs are superior to intranasal GCS in relieving nasal congestion. For example, antihistamines are not effective in relieving congestion.1 Oral decongestants are somewhat beneficial in relieving nasal congestion but can elevate blood pressure, cause restlessness, and cause urinary retention. Oxymetazoline, however, is a potent decongestant and the addition of it to a nasal GCS should add a considerable decongestant benefit. It may also be beneficial in patients with persistent nighttime congestion despite maximum dosages of nasal GCS. Oxymetazoline is currently recommended for three days use because of the proposed risk of rhinitis medicamentosa,4 which is increased nasal congestion caused by prolonged use of nasal decongestant sprays.5-8 The term RM was coined early in the twentieth century after several case reports described patients developing rebound congestion after using first generation intranasal decongestants such as privine hydrochloride and ephedrine for prolonged periods6,7. The histopathology and mechanism of RM has been based on animal models which may not be pertinent to humans.9-13 Studies using oxymetazoline, a newer intranasal decongestant, in individuals without rhinitis have shown conflicting evidence for the development of RM.14-16 For example, normal individuals without rhinitis using oxymetazoline three times daily for four weeks did not develop RM.17 Also, it is unknown the frequency of administration and dosage of oxymetazoline it takes to induce RM or whether RM is just a return to a patient's baseline nasal congestion as present before beginning oxymetazoline. It is also unknown whether RM is more likely or only occurs with older vasoconstrictors such as privine hydrochloride and ephedrine rather than oxymetazoline. Nasal GCS reduce the amount of rebound congestion in patients with perennial allergic rhinitis who have reportedly developed RM.18 Nasal GCS decrease nasal mucosa edema, recruitment of neutrophils and mononuclear cells, cytokine production, and late-phase nasal mediators.19-21 They may offer a protective benefit from the risk of developing RM. Oxymetazoline may also decrease inferior turbinate hypertrophy thereby permitting better adsorption of the nasal GCS. Hypothesis The addition of oxymetazoline to a nasal GCS for fourteen days will decrease the amount of congestion in subjects with allergic or non-allergic rhinitis with persistent congestion despite maximum recommended dosages of a nasal GCS. It is also hypothesized that nasal GCS protect against the development of RM secondary to oxymetazoline.

15 mg dextromethorphan hydrobromide will be better than placebo with respect to reducing the number of coughs over 6 hours and reducing the subjective severity of cough over 6 hours.

This study will be a prospective observation of the use of commercially available hemp and cannabis products marketed for immune support.

Study to assess the efficacy and safety of XC8, film-coated tablets, 10 mg in comparison with placebo in patients with dry non-productive cough against acute respiratory infection.

The study is planned to evaluate the therapeutic efficacy and safety of Ingavirin®, syrup, 30 mg/5 ml, in the treatment of influenza or other acute respiratory infections in children from 6 months to 2 years compared with placebo.

The purpose of this study is to determine whether Ingavirin ® dosed 30 mg daily is effective and safe in the treatment of influenza and other acute respiratory viral infections in the course of standard therapy in 3-6 years old patients.

The purpose of this study is to investigate the efficacy of Phytus in Acute Cough

The purpose of this study is to determine whether Ingavirin ® dosed 60 mg daily is effective and safe in the treatment of influenza and other acute respiratory viral infections in 7-12 years old patients.
