Ivy Leaf (Hedera helix) as a tool for helping with Respiratory support

Objective Introduction: Coughing is a physiological, spontaneous defense mechanism against irritants that stimulate respiratory mucosa. Productive cough should be not suppressed; instead, mucus-dissolving agents are recommended. One of the expectorants, which increases the excretion volume, is the herbal medicine derived from ivy leaves. The ivy extract contains triterpene saponins, which have secretory properties. The aim of this study was to determine the effectiveness and safety of the treatment with the medicinal product Hedussin®, containing dry ivy extract, in the therapy of productive cough in the course of the respiratory tract infection. Patients and methods Material and methods:This was a non-randomized, non-interventional, multicenter, open-label, post-authorization effectiveness study (PAES). The study group consisted of 464 patients aged 2-12 years with productive cough. The study was supported by a questionnaire that included: the type of cough etiological factor, Bronchitis Severity Score (BSS), temperature, and prescription of antibiotic therapy. Effectiveness and safety of the therapy with Hedussin® was assessed at the follow-up visit. Results Results and conclusion: Improvement in cough was reported in 93.3% subjects; improvement in chest pain on coughing was reported in 84.7%, in wheezing - in 90.0%, in dyspnoea - in 88.7%, and in auscultation changes - in 94.8%. In addition, decline or normalization of body temperature was found in 96.0% of subjects. No adverse drug reactions were reported in the study population. The non-antibiotic treated group showed similar proportions. The results of this study support the efficacy of Hedussin® prescribed for the treatment of productive cough in the course of respiratory tract infections. Hedussin® was well tolerated by sick children aged 2-12 years.

This randomized, placebo-controlled, double-blind trial was conducted to assess the efficacy and safety of ivy leaves cough liquid in the treatment of acute cough. A total of 181 adult patients with acute cough were treated with either ivy leaves cough liquid containing EA 575® or with placebo three times a day for one week. The primary efficacy outcome was cough severity (CS) assessed by Visual Analogue Scale (VAS) over the whole treatment period (area-under-the-curve (AUC0-168 h) over 7 days (visit (V)1, V2, V3, V4, and V5). The secondary endpoints were defined as the CS assessed by VAS over the whole observation period (V1 - V6) and by Bronchitis Severity Score (BSS) and Verbal Category Descriptive (VCD) score. The evaluation of the VAS, BSS and VCD score revealed that subjects treated with ivy leaves cough liquid showed statistically significant and clinically relevant reductions in CS, severity of symptoms associated with cough and bronchitis compared to the placebo group. Furthermore, a remarkable early onset of efficacy was observed as significant reductions of cough severity were detected within 48 hours after the first drug intake. At all following visits and even 7 days after the end of treatment (V6) this significant treatment advantage was detected in comparison to placebo. All adverse events (AEs) in this clinical trial were non-serious, mild or of moderate severity and not drug-related. This clinical trial proved consistent superiority of the ivy leaves cough liquid treatment versus placebo and confirmed the EA 575® preparation to be a safe and efficacious option for the treatment of acute cough.

Introduction Acute bronchitis is defined as a sudden inflammation of the bronchial tubes in the lung mainly caused by viral infection. It is characterized by a persistent cough which can be productive or dry. It is the most common disease in industrialized countries, and thus herbal expectorants enjoy a high popularity in many European countries due to their favorable risk-benefit ratio. Objective The present noninterventional study was intended to gain further data on the application of a cough syrup containing ivy leaf extract EA 575® by evaluating its efficacy and safety in children and adults with symptoms of acute bronchitis. Acetylcysteine (ACC) was chosen as comparator drug (common mono preparations). Material and Methods . The study was conducted at 25 medical practices throughout Switzerland as prospective, open, noninterventional study. Results At entry visit, all clinical assessments including coughing fits, sputum, dyspnoea, rales, severity of the diseases, and coughing quality were rated with moderate intensity in both groups. At the final visit after seven days of treatment, there was a comparable improvement in both groups for all assessments except dyspnoea and number of cough attacks which showed a higher improvement in the EA 575® group compared with ACC. Further, cough-associated sleeping disorders improved more in the EA 575® group. Both, physicians and patients described the efficacy of EA 575® comparable with acetylcysteine. Observations of the tolerability were comparable for both products. The study results indicate that ivy leaf extract might be an effective alternative to acetylcysteine with respect to the improvement of respiratory function in children and adults at a slightly better evaluation of efficacy.
