What is Erdosteine?

Description

Erdosteine is a new expectorant introduced in France for the treatment of chronic bronchitis. Erdosteine possesses mucomodulator, mucolytic, mucokinetic and free radical scavenging properties. Its therapeutic efficacy has been demonstrated in patients affected by congestion and viscous mucus in higher and lower respiratory tracts as in acute and chronic bronchitis, sinusitis, otitis, tracheopharyngitis and coryza. Erdosteine acts through its active metabolites containing free sulfhydryl groups which are able to depolymerize the mucopolysaccharides of the excreatum by breaking the disulfide linkages (thereby lowing its viscosity). The prodrug approach provides unique characteristics to erdosteine by offering stable therapeutic efficacy and prevention of the gastric mucus from lythic phenomena. The agent was also reported to have local antiinflammatory and antielastase properties and enhances penetration of antibiotics into bronchial mucus.

Description

Erdosteine is a mucolytic agent and an antioxidant. It inhibits LPS-induced IκB kinase (IKK) activity, NF-κB-mediated transcription, and production of IL-6 and IL-1β in RAW 264.7 cells. Erdosteine (7.5 mg/kg) prevents depletion of renal catalase and glutathione peroxidase (GPX) and increases in renal malondialdehyde (MDA) and nitric oxide (NO) levels in a rat model of nephrotoxicity induced by cisplatin . It reduces spinal cord lipid peroxidation and destruction of spinal motor neurons in a rabbit model of spinal cord ischemia and reperfusion injury induced by thoracoabdominal aortic clamping. Erdosteine (150 mg/kg) reduces lung weight, MDA and protein carbonyl levels, and macrophage and neutrophil accumulation in a mouse model of acute lung injury induced by oleic acid (Item Nos. 90260 | 24659). Formulations containing erdosteine have been used in the treatment of chronic obstructive pulmonary disease (COPD).

The Uses of Erdosteine

A mucolytic, developed for the treatment of chronic obstructive bronchitis.

Indications

Fro the treatment of chronic bronchitis in adults.

Background

Erdosteine is a drug that causes a breakdown of mucus, also known as a mucolytic agent. It is a thiol derivative produced for the clinical management of chronic obstructive bronchitis, in addition to infective exacerbations of chronic bronchitis. This drug contains sulfhydryl groups which are released after erdosteine undergoes hepatic first pass metabolism. Three active metabolites result and possess mucolytic activity in addition to free radical scavenging activity. Erdosteine acts to control mucus production and control its viscosity while increasing mucociliary transport. It also combats the effects of free radicals resulting from cigarette smoke. Erdosteine has been shown to be safe and well tolerated in clinical trials. Erdosteine 300mg twice daily reduced cough (both frequency and severity) and sputum viscosity more quickly and more effectively than placebo and reduced the adhesivity of sputum more effectively than ambroxol 30mg twice daily. Co-administration of erdosteine and amoxicillin in patients with acute infective exacerbation of chronic bronchitis resulted in higher concentrations of the antibiotic in the sputum, leading to earlier and more pronounced amelioration of clinical symptoms compared with placebo. Erdosteine is associated with a low incidence of adverse events, most of which are gastrointestinal and generally mild.
