(RS)-Carbocisteine is primarily used as a mucolytic agent in the treatment of respiratory conditions. It works by breaking down the disulfide bonds in mucus, making it less viscous and easier to expel from the airways. This property makes it particularly effective in managing chronic obstructive pulmonary disease (COPD), bronchitis, and other respiratory disorders characterized by excessive mucus production. Additionally, it is often prescribed to patients with sinusitis or otitis media to help alleviate symptoms associated with thickened mucus. The compound is also known to enhance the efficacy of antibiotics in respiratory infections by improving their penetration into the mucus layer. Its use is common in both adult and pediatric populations, providing relief from persistent cough and congestion.
