A double-blind clinical study with Monydrin tablets in patients with non-allergic chronic rhinitis.
Oral combination preparations (antihistamine + sympathomimetic) are widely used for nasal and sinus congestion without the presence of allergy. The use of antihistamine in these cases may be questioned. Evaluation of the clinical effect of only a sympathomimetic agent on patients with nonallergic rhinitis is performed in a double-blind clinical study on seventy patients. Phenylpropanolamine (50 mg and 100 mg) was compared with placebo. It was found that 100 mg phenylpropanolamine was significantly more active than 50 mg or placebo administered orally as a sustained-release tablet twice daily. No side-effects such as CNS stimulation and influence on blood pressure were seen at any of the dose levels.
