Product Detail

Carbocisteine is a widely used mucolytic expectorant with demonstrated efficacy in the treatment of respiratory conditions. This medication works by regulating the secretory function of bronchial glands, effectively reducing sputum viscosity and enhancing respiratory ciliary movement to facilitate mucus expulsion. It is primarily indicated for symptoms of thick sputum and difficult expectoration associated with chronic bronchitis, bronchial asthma, and other respiratory disorders. The product demonstrates favorable safety and tolerability profiles when used as directed, providing an effective therapeutic option for patients experiencing difficulty in expectorating respiratory secretions.

ECHEMI Editorial Reference

white to slightly off-white amorphous powder
S-carboxymethyl-L-cysteine is an L-cysteine thioether that is L-cysteine in which the hydrogen of the thiol group has been replaced by a carboxymethyl group. It has a role as a mucolytic. It is a L-cysteine thioether and a non-proteinogenic L-alpha-amino acid. It is a conjugate acid of a S-carboxylatomethyl-L-cysteine(1-).|Carbocisteine is a mucolytic that reduces the viscosity of sputum to relieve the symptoms of chronic obstructive pulmonary disorder (COPD) and bronchiectasis through easier expulsion of mucus. Carbocisteine should not be used with antitussives (cough suppressants) or medicines that dry up bronchial secretions as they are functional antagonists. Carbocisteine is produced by alkylation of cysteine with chloroacetic acid.|A compound formed when iodoacetic acid reacts with sulfhydryl groups in proteins. It has been used as an anti-infective nasal spray with mucolytic and expectorant action.
