Aim To investigate the effects of carbocisteine treatment in the reduction of frequency of productive cough episodes, preventing disease progression and improving the quality of life as well as the tolerability of the administered treatment and patient compliance during the study. Methods This observational, non-interventional, multicenter, cohort study included 501 patients with chronic obstructive pulmonary disease (COPD) who were administrated carbocisteine capsules 375 mg and followed up during the next 15 days. The patients were observed at 3 points, baseline and two additional assessments. General clinical condition of patients, along with the spirometry testing at all three points were examined. Thr quality of life was assessed on the 1st and 3rd observation with Leicester Cough Questionnaire. Tolerability and patient compliance were measured throughout the study. Results There was a significant change of forced expiratory volume in 1 second (FEV1) status between the second and third observation (p=0.002). Examination of general symptoms showed a statistically significant reduction in cough by 74.9%, in sputum production by 48.5%, in dyspnea by 29% and in fatigue by 50%. After the administration of carbocisteine the median value of overall quality of life was 3.79 (3.63 - 3.89). Conclusion 375mg carbocisteine capsules were found to be effective and well-tolerated in the treatment of COPD, with a small percentage of reported mild adverse reactions and with a significant improvement of quality of life.

Background: Nifuroxazide is well known and often used anti-diarrhoeal medicine which has been pushed back from routine practice in recent years and often replaced with probiotics. Even probiotics are accepted and placed in some therapeutic guidelines for diarrhoea treatment, there are no enough evidence for its effectiveness and no comparative efficacy data with nifuroxazide in treatment of acute diarrhea. Patients and Methods: In open, prospective observational study, the efficacy and safety of nifuroxazide were compared with a probiotic containing lactic acid bacteria in the treatment of acute diarrhoea. A total number of 169 adult patients were included in this study, who administered nifuroxazide in the dose of 200 mg/4 times a day, while they took preparation containing lactic acid bacteria (1,2 x 107 live lyophilised lactic-acid bacteria) three times a day for three days. Results: Mean time to last unformed stool (TLUS) in a group which was treated with nifuroxazide was two days, while it took five days for the stool normalisation in the group using probiotic (p=0.0001). Conclusions: Orally administered nifuroxazide has demonstrated better efficiency as compared to probiotic in treating acute diarrhoea, and both medicines have shown the same safety and tolerance in this study.

Introduction: Tonsillopharyngitis (sore throat) is a common disease mainly related to the seasonal common cold. To relieve unpleasant symptoms and discomfort of acute tonsillopharyngitis associated with common cold, patients usually take some non-prescription drugs. The aim: The primary aim of this study was to assess subjective determinations of the efficacy and the safety/tolerability of an oral spray comprising a combination of lysozyme chloride and cetylpyridinium chloride in those patients. Material and methods: The study involved 1727 patients with tonsillopharyngitis associated with common cold and treated with the studied drug, in the period from December 2014 through March 2015. Results: In total, 95% of patients rated the studied drug to be well, very well and excellently effective. In 32% of patients, the symptoms were relieved 10 minutes after the application of the spray. Significant correlations were found between the two subjective assessments of the drug efficiency with the total of 74.11% (95% CI: 73.41, 77.47%) of patients who said that the feeling of pain in the throat completely disappeared after the drug administration, evaluated the impact/effect of the drug was very good or good (Pearson Chi Square=391.401, p<0.001). The effectiveness was significantly better in patients with up to two episodes of common cold a year (Pearson Chi Square=6.101; p=0.014). The studied drug was rated to be well, very well and excellently tolerated by 97% of patients. Conclusion: According to patients’ subjective assessment, the combination of lysozyme chloride and cetylpyridinium chloride in a formulation of spray can quickly, efficiently and safely resolve the symptoms of acute tonsillopharyngitis associated with common cold.
