POM: Prescription only medicine
This information is intended for use by health professionals
Aurobeverine MR 200 mg modified-release capsules, hard
Each capsule contains 200 mg mebeverine hydrochloride
Excipient with known effect:
Each capsule contains up to 23.81 mg sucrose.
For the full list of excipients, see section 6.1.
Modified-release capsule, hard.
Creamy white body and creamy white cap, hard gelatin capsule (approximately 9.8 mm x 6.9 mm) filled with white to off white spherical pellets.
Adults and children over 10 years.
For the symptomatic relief of irritable bowel syndrome.
Adults and children over 10 years:
One capsule of 200 mg twice daily; one in the morning and one in the evening.
There are no safety risks for continued use up to a period of 1 year. However, once the desired effect is achieved after several weeks, the dose can be gradually reduced.
If one or more doses are missed, the patient should continue with the next dose as prescribed; the missed dose(s) should not be taken in addition to the regular dose.
Aurobeverine MR is not recommended for use in children aged under 10 years as the safety and effectiveness has not been established in this group.
No posology studies in elderly, renal and/or hepatic impaired patients have been performed. No specific risk for elderly, renal and/or hepatic impaired patients could be identified from available post-marketing data.
Method of administration
Aurobeverine MR should be swallowed with a sufficient amount of water (at least 100 ml water). They should not be chewed because the coating is intended to ensure a controlled release (see section 5.2).
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1
Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrose-isomaltese insufficiency should not take this medicine.
No interactions of mebeverine are known.
There are no or limited amounts of data from the use of mebeverine in pregnant women. Animal studies are insufficient with respect to reproductive toxicity (see section 5.3). Mebeverine is not recommended during pregnancy.
It is unknown whether mebeverine or its metabolites are excreted in human milk. The excretion of mebeverine in milk has not been studied in animals. Mebeverine should not be used during breast-feeding.
There are no clinical data on male or female fertility; however, animal studies do not indicate harmful effects of mebeverine (see section 5.3).
No studies on the effects on the ability to drive and use machines have been performed. The pharmacodynamic and pharmacokinetic profile as well as postmarketing experience do not indicate any harmful effect of mebeverine on the ability to drive or to use machines.
The following adverse reactions have been reported spontaneously during postmarketing use. A precise frequency cannot be estimated from available data.
Allergic reactions mainly but not exclusively limited to the skin have been observed.
Immune system disorders: Hypersensitivity (anaphylactic reactions).
Skin and subcutaneous tissue disorders: Urticaria, angioedema, face oedema, exanthema.
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 the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.
Theoretically CNS excitability may occur in cases of overdose. In cases where mebeverine was taken in overdose, symptoms were either absent or mild and usually rapidly reversible. Observed symptoms of overdose were of a neurological and cardiovascular nature.
No specific antidote is known and symptomatic treatment is recommended.
Gastric lavage should only be considered in case of multiple intoxication or if discovered within about one hour. Absorption reducing measures are not necessary.
Pharmacotherapeutic group: Synthetic anticholinergics, esters with tertiary amino group, ATC code: A03A A04
Mechanism of action and pharmacodynamics effects
Mebeverine is a musculotropic antispasmodic with a direct action on the smooth muscle of the gastrointestinal tract, relieving spasm without affecting normal gut motility. Since the autonomic nervous system is not involved in this mechanism of action, typical systemic anticholinergic side-effects are absent.
Clinical efficacy and safety
All formulations of mebeverine were generally safe and well tolerated in the recommended dose regimen.
Mebeverine is rapidly and completely absorbed after oral administration of tablets. The modified release formulation permits a twice daily dosing scheme.
No significant accumulation occurs after multiple doses.
Mebeverine hydrochloride is mainly metabolised by esterases, initially splitting the ester bonds into veratric acid and mebeverine alcohol. The main metabolite in plasma is DMAC (Demethylated carboxylic acid). The steady state elimination half-life of DMAC is 5.77h. During multiple dosing (200 mg b.i.d.) the Cmax of DMAC is 804 ng/ml and tmax is about 3 hrs. The relative bioavailability of the modified release capsule appears to be optimal with a mean ratio of 97%.
Mebeverine is not excreted as such, but metabolised completely; the metabolites are excreted nearly completely. Veratric acid is excreted into the urine; mebeverine alcohol is also excreted into the urine, partly as the corresponding carboxylic acid (MAC) and partly as the demethylated carboxylic acid (DMAC).
No pharmacokinetic studies have been performed in children under 10 years old.
Effects in repeat-dose toxicity studies, after oral and parenteral doses, were indicative of central nervous involvement with behavioural excitation, mainly tremor and convulsions. In the dog, the most sensitive species, these effects were seen at oral doses equivalent to 3 times the maximum recommended clinical dose of 400 mg/day based on body surface area (mg/m2) comparisons.
The reproductive toxicity of mebeverine was not sufficiently investigated in animal studies.
There was no indication of teratogenic potential in rats and rabbits. However, embryotoxic effects (reduction in litter size, increased incidence of resorption) were noticed in rats at doses equivalent to twice the maximum daily clinical dose. This effect was not observed in rabbits. No effects on male or female fertility were noted in rats at doses equivalent to the maximum clinical dose.
In conventional in vitro and in vivo genotoxicity tests mebeverine was devoid of genotoxic effects. No carcinogenicity studies have been performed.
