Comparative Analysis of Classic and Novel Antitussives on Cough Suppression in Guinea Pigs. (PubMed, Pharmaceutics) - " This study evaluated and compared the antitussive efficacy of classic (codeine, cloperastine, dextromethorphan, levodropropizine) and novel (gefapixant) agents using a citric acid-induced cough model in guinea pigs. These findings highlight the potential clinical relevance of both centrally and peripherally acting non-opioid alternatives. Continued investigation of these agents may help address the unmet need for safer and more effective cough treatments."

Pharmacologic Interventions for Symptomatic Treatment of Cough among Adults with Lung Malignancy: A Systematic Review and Meta-Analysis (APSR 2025) - "Results : Thirteen studies met the inclusion criteria and these examined the use of aprepitant (two), levodropropizine (three), opioid and its derivatives (six), paroxetine (one), and pregabalin (one). Aprepitant showed significant improvement in cough among lung cancer patients. Additional good quality trials are recommended to refine and expand current guideline recommendations."

PHARMACOLOGIC INTERVENTIONS FOR SYMPTOMATIC TREATMENT OF COUGH AMONG ADULTS WITH LUNG MALIGNANCY: A SYSTEMATIC REVIEW AND META-ANALYSIS (CHEST 2025) - " Thirteen studies met the inclusion criteria and these examined the use of aprepitant (two studies), levodropropizine (three studies), opioid and its derivatives (six studies), paroxetine (one study), and pregabalin (one study). The most common presenting symptom of lung cancer remains undertreated with limited pharmacologic options available. Aprepitant showed significant improvement in cough among lung cancer patients. There remains a need increase the quality and number of studies in the effectiveness of medications for cough in lung cancer."

PREVALENCE AND ASSOCIATED RISK FACTORS OF HEPATITIS B VIRUS INFECTION IN LAFIA METROPOLIS, NASARAWA STATE, NIGERIA. (PubMed, Afr J Infect Dis) - "A cross-sectional study was conducted from September to November 2023, utilizing a validated questionnaire to assess 461 randomly selected participants from four communities (Azuba, Bukan Sidi, Danka Sarki, and Doka), representing diverse sociodemographic profiles and varying degrees of exposure to risk factors associated with HBV infection...These findings highlight the need for targeted public health interventions and policies aimed at reducing HBV transmission among high-risk sociodemographic groups in Lafia Metropolis. This approach could potentially reduce the burden of HBV and improve health outcomes in affected communities."

Peripheral antitussives affect temporal features of tracheobronchial coughing in cats. (PubMed, J Appl Physiol (1985)) - "Peripherally acting antitussives 3-Aminopropylphosphinic Acid (3APPi, 5mg/kg) and levodropropizine (Levo, 3mg/kg) were injected i.v. in anesthetized spontaneously breathing cats (13 males, 2 females; 4.38 ± 0.19 kg)...Peripherally induced cough suppression is accompanied with changes in cough temporal characteristics that are not observed after administration of centrally acting antitussives. The motor output produced by the cough central pattern generator differs significantly when coughing is perturbed by peripherally and centrally acting antitussives."

Levodropropizine for children and adolescents with acute post-viral cough: an evidence-based choice. (PubMed, Minerva Pediatr (Torino)) - "Non-pharmacological remedies tend to be safe, but few substances have a documented degree of efficacy. Therefore, when managing children and adolescents with a post-viral cough, the practical approach may be based on levodropropizine use, which is preferable when the cough is particularly persistent and disturbs sleep."

Pharmacokinetic Analysis of Levodropropizine and Its Potential Therapeutic Advantages Considering Eosinophil Levels and Clinical Indications. (PubMed, Pharmaceuticals (Basel)) - "Interestingly, changes in an individual's plasma exposure to levodropropizine depending on eosinophil levels could be interpreted as a therapeutic advantage based on pharmacokinetic benefits linked to the clinical indications for levodropropizine. This study presents effective candidate covariates that can explain the inter-individual pharmacokinetic variability of levodropropizine and provides a useful perspective on the first-line choice of levodropropizine in the treatment of inflammatory respiratory diseases."
