Levodropropizine in the Management of Cough Associated with Cancer or Nonmalignant Chronic Disease–A Systematic Review

The Mechanisms Involved in Morphine Addiction: An Overview

Opioid use disorder is classified as a chronic recurrent disease of the central nervous system (CNS) which leads to personality disorders, co-morbidities and premature death. It develops as a result of long-term administration of various abused substances, along with morphine. The pharmacological action of morphine is associated with its stimulation of opioid receptors. Opioid receptors are a group of G protein-coupled receptors and activation of these receptors by ligands induces significant molecular changes inside the cell, such as an inhibition of adenylate cyclase activity, activation of potassium channels and reductions of calcium conductance. Recent data indicate that other signalling pathways also may be involved in morphine activity. Among these are phospholipase C, mitogen-activated kinases (MAP kinases) or β-arrestin. The present review focuses on major mechanisms which currently are considered as essential in morphine activity and dependence and may be important for further studies.

Global Strategy for the Diagnosis, Management, and Prevention of Chronic Obstructive Lung Disease 2017 Report. GOLD Executive Summary

This Executive Summary of the Global Strategy for the Diagnosis, Management, and Prevention of COPD, Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 report focuses primarily on the revised and novel parts of the document. The most significant changes include: (1) the assessment of chronic obstructive pulmonary disease has been refined to separate the spirometric assessment from symptom evaluation. ABCD groups are now proposed to be derived exclusively from patient symptoms and their history of exacerbations; (2) for each of the groups A to D, escalation strategies for pharmacologic treatments are proposed; (3) the concept of deescalation of therapy is introduced in the treatment assessment scheme; (4) nonpharmacologic therapies are comprehensively presented; and (5) the importance of comorbid conditions in managing chronic obstructive pulmonary disease is reviewed.

Symptomatic Treatment of Cough Among Adult Patients With Lung Cancer: CHEST Guideline and Expert Panel Report

BACKGROUND

Cough among patients with lung cancer is a common but often undertreated symptom. We used a 2015 Cochrane systematic review, among other sources of evidence, to update the recommendations and suggestions of the American College of Chest Physicians (CHEST) 2006 guideline on this topic.

METHODS

The CHEST methodologic guidelines and the Grading of Recommendations, Assessment, Development, and Evaluation framework were used. The Expert Cough Panel based their recommendations on data from the Cochrane systematic review on the topic, uncontrolled studies, case studies, and the clinical context. Final grading was reached by consensus according to the Delphi method.

RESULTS

The Cochrane systematic review identified 17 trials of primarily low-quality evidence. Such evidence was related to both nonpharmacologic (cough suppression) and pharmacologic (demulcents, opioids, peripherally acting antitussives, or local anesthetics) treatments, as well as endobronchial brachytherapy.

CONCLUSIONS

Compared with the 2006 CHEST Cough Guideline, the current recommendations and suggestions are more specific and follow a step-up approach to the management of cough among patients with lung cancer, acknowledging the low-quality evidence in the field and the urgent need to develop more effective, evidence-based interventions through high-quality research.

Shortness of breath and cough in patients in palliative care

BACKGROUND

Shortness of breath and cough are common, disturbing symptoms in patients receiving palliative care. They arise in 10% to 70% of patients with advanced cancer and in 60% to nearly 100% of patients with non-malignant underlying diseases, depending on the type of disease.

METHODS

This review is based on a selective literature search in the Medline, Embase, and PsycInfo databases and on current recommendations from Germany and other countries, as well as on the authors' personal experience.

RESULTS

Some general measures to address these problems are reassurance, development of an emergency plan, physical activity, and relaxation exercises. Supportive non-pharmacological measures may include the use of a rollator (level of evidence [LoE] 1-), a cool draft of air as from a handheld fan (LoE 1-), physiotherapy, and respiratory therapy. There is good evidence (LoE 1+) to support the administration of opioids as the medications of choice; benzodiazepines are often used, but a meta-analysis did not reveal any statistically significant benefit (LoE 1+). Expectorants can help patients who cough with marked sputum formation. Antitussants suppress the cough reflex both peripherally and centrally (LoE 1+ to 3). Opioids, including morphine (LoE 1-) and dextromethorphan (LoE 1-), are effective antitussants with low toxicity.

CONCLUSION

In most patients, shortness of breath and cough can be relieved by a series of therapeutic measures.
