The World Health Organization's ATC classification organizes medical drugs based on therapeutic properties, chemical composition, and anatomy. It helps make essential medicines readily available globally and is widely used in the pharmaceutical industry.
Acetylcysteine is N-acetyl derivative of cysteine. Used as a mucolytic agent to reduce the viscosity of mucous secretions.
Ambroxol induces activation of the surfactant system by acting directly on the type II pneumocytes of the alveoles and the Clara cells in the region of the small airways. It promotes the formation and outward transfer of surface-active material in the alveolar and bronchial region of the foetal and adult lungs.
Bromhexine is an expectorant used in the treatment of respiratory disorders associated with viscid or excessive mucus. Bromhexine is a synthetic derivative of the herbal active ingredient vasicine. It has been shown to increase the proportion of serous bronchial secretion, making it more easily expectorated. It is indicated as “secretolytic therapy in bronchopulmonary diseases associated with abnormal mucus secretion and impaired mucus transport”.
Carbocisteine (5-carboxymethyl L-cysteine) has been shown in normal and bronchitic animal models to affect the nature and amount of mucus glycoprotein that is secreted by the respiratory tract. An increase in the acid:neutral glycoprotein ratio of the mucus and a transformation of serous cells to mucus cells is known to be the initial response to irritation and will normally be followed by hypersecretion.
Recombinant human DNase is a genetically engineered version of a naturally occurring human enzyme which cleaves extracellular DNA. In vitro, dornase alfa hydrolyses DNA in sputum and greatly reduces the viscoelasticity of cystic fibrosis sputum.
Erdosteine is a mucolytic agent reducing the viscosity of mucus and purulent sputum. Erdosteine is a prodrug, becoming active after metabolism whereby free thiol groups are formed.
Mesna is an antidote, and offers the possibility of reliably preventing urotoxic side-effects associated with aggressive cancer chemotherapy using oxazaphosphorine cytostatics.
Sobrerol is a mucolytic known due its emplyment in therapy for respiratory diseases. In preclinical studies sobrerol, administered daily at the oral dose of 400 mg/rat, markedly decreased the monocrotaline-induced alterations and regulate the development of pulmonary hypertension. Treatment with sobrerol was well tolerated and significantly reduced frontal headache and rhinorrhoea, efficacy being confirmed by rhinomanometry.
