Carbocisteine 375mg Capsules
Each capsule contains carbocisteine 375mg.
For the full list of excipients, see section 6.1.
Size 0 capsule with opaque blue cap and opaque yellow body, containing white to off-white odourless powder.
Carbocisteine is a mucolytic agent for the adjunctive therapy of respiratory tract disorders characterised by excessive, viscous mucus, including chronic obstructive airways disease.
Adults including the elderly
Dosage is based upon an initial daily dosage of 2250 mg carbocisteine (6 capsules) in divided doses, reducing to 1500 mg (4 capsules) daily in divided doses when a satisfactory response is obtained. For example, two capsules three times a day reducing to one capsule four times a day.
This formulation is not recommended for use in children.
Method of administration
For oral use.
• Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
• Use in patients with active peptic ulceration.
Caution is recommended in the elderly, in those with a history of gastroduodenal ulcers, or those taking concomitant medications known to cause gastrointestinal bleeding. If gastrointestinal bleeding occurs, patients should discontinue medication.
There are no known interactions with other medicinal products or other forms of interaction.
Although tests in mammalian species have revealed no teratogenic effects, carbocisteine is not recommended during the first trimester of pregnancy.
It is unknown whether carbocisteine and / or its metabolites are excreted in human milk. A risk to the newborn or infant cannot be excluded.
A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from carbocisteine therapy taking into account the benefit of breast feeding for the child and the benefit of therapy for the woman.

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via Yellow Card Scheme Website: www.mhra.gov.uk/yellowcard
Gastric lavage may be beneficial, followed by observation. Gastrointestinal disturbance is the most likely symptom of carbocisteine overdosage.
Pharmacotherapeutic group: Mucolytic, ATC code: R05C B03
Mechanism of action
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.
The administration of carbocisteine to animals exposed to irritants indicates that the glycoprotein secreted remains normal; administration after exposure indicates that return to the normal state is accelerated.
Studies in humans have demonstrated that carbocisteine reduces goblet cell hyperplasia. Carbocisteine can therefore play a role in the management of disorders characterised by abnormal mucus.
Carbocisteine is rapidly absorbed from the GI tract.
Equilibrium pharmacokinetics were established in healthy volunteers following administration of carbocisteine 375mg capsules, 2 capsules t.d.s. for seven days. The mean Tmax was 2.0 hours (range 1.0 –3.0); T½ 1.87 hours (range 1.4 – 2.5); KEL 0.387 hour-1 (range 0.28 – 0.50) and AUC0-7.5 was 39.26 mcg.hr/ml (range 26.0 – 62.4). Values for derived pharmacokinetic values were CLS 331ml.min-1; VD 105.2 L and VD 1.4 L/Kg.
