Carbocysteine More Info

Carbocysteine is a mucolytic agent used primarily to treat respiratory conditions characterized by thick, sticky mucus, such as chronic bronchitis and chronic obstructive pulmonary disease (COPD). It helps break down mucus, making it easier to cough up.

Mechanism of Action

Carbocysteine works by breaking disulfide bonds in mucoproteins, which are components of mucus. This action reduces the viscosity of mucus, facilitating its clearance from the airways and improving respiratory function.

Applications

Carbocysteine is used for:
Chronic Bronchitis: It helps manage symptoms by reducing mucus viscosity and improving expectoration.
Chronic Obstructive Pulmonary Disease (COPD): Carbocysteine is used to alleviate symptoms associated with COPD, such as chronic cough and sputum production.
Other Respiratory Conditions: It may be used off-label for conditions like asthma or bronchiectasis.

Safety and Side Effects

Carbocysteine is generally well-tolerated, but some side effects may occur:
Common Side Effects:
Gastrointestinal disturbances (nausea, diarrhea)
Headache
Dizziness
Allergic reactions (rare)
Less Common Side Effects:
Skin rash or itching
Increased risk of bronchospasm in asthmatic patients
Serious side effects require immediate medical attention.

Routes of Administration

Carbocysteine is administered orally in capsule or syrup form.

Pharmacokinetics

Absorption: Carbocysteine is well absorbed after oral administration.
Distribution: It has a moderate volume of distribution, indicating distribution into tissues.
Metabolism: Carbocysteine is metabolized by the liver.
Elimination: The half-life of carbocysteine is approximately 1.5 hours. It is primarily excreted via urine.

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S-carboxymethyl-L-cysteine is an L-cysteine thioether that is L-cysteine in which the hydrogen of the thiol group has been replaced by a carboxymethyl group.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.
