In case severe, unexplained abdominal pain persists or worsens, or occurs together with symptoms

like fever, nausea, vomiting, changes in bowel movements, abdominal tenderness, decreased blood

pressure, fainting or blood in stool, medical advice should immediately be sought where appropriate

diagnostic measures are needed to investigate the etiology of the symptoms.

Hyoscine may cause drowsiness: patients so affected should not drive or operate machinery. Patients

should abstain from alcohol. However, as a quaternary ammonium compound with low lipid

solubility, BUSCOPAN cannot cross the blood/brain barrier easily and only rarely causes the central

nervous system side effects associated with atropine and hyoscine.

After parenteral administration of BUSCOPAN, patients with visual accommodation disturbances

should not drive or operate machinery until vision has normalised.

Because of the potential risk of anticholinergic complications, BUSCOPAN and BUSCOPAN

FORTE tablets should be administered with caution in patients susceptible to narrow angle

glaucoma, intestinal or urinary outlet obstruction, and those inclined to tachyarrhythmia.

Elevation of intraocular pressure may be produced by the administration of anticholinergics such as

BUSCOPAN and BUSCOPAN FORTE in patients with undiagnosed and therefore untreated narrow

angle glaucoma. Therefore, patients should seek urgent ophthalmological advice if they should

develop a painful, red eye with loss of vision after the injection of BUSCOPAN and BUSCOPAN


After parenteral administration of BUSCOPAN, cases of anaphylaxis including episodes of shock

have been observed. As with all drugs causing such reactions, patients receiving BUSCOPAN by

injection should be kept under observation.

Caution is needed in patients with cardiac conditions submitted to parenteral treatment with

BUSCOPAN. Monitoring of these patient is advised.

BUSCOPAN injection can cause tachycardia, hypotension and anaphylaxis, therefore use with

caution in patients with cardiac conditions such as cardiac failure, coronary heart disease, cardiac

arrhythmia or hypertension, and in cardiac surgery. Monitoring of these patients is advised.

Emergency equipment and personnel trained in its use must be readily available.

One sugar-coated tablet of 10 mg contains 41.2 mg sucrose, resulting in 329.6 mg sucrose per

maximum recommended daily dose. Patients with the rare hereditary condition of fructose

intolerance should not take this medicine.

One film-coated tablet of 20 mg contains 138.5 mg lactose, resulting in 554 mg lactose per

maximum recommended daily dose. Patients with the rare hereditary conditions of galactose

intolerance e.g. galactosaemia, the Lapp lactase deficiency or glucose-galactose malabsorption

should not take this medicine.

There is limited data from the use of hyoscine-N-butylbromide in pregnant women.

Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity

(please refer to Section 5.3).

There is insufficient information on the excretion of hyoscine-N-butylbromide and its metabolites in

human milk.

As a precautionary measure, it is preferable to avoid the use of BUSCOPAN and BUSCOPAN

FORTE during pregnancy and lactation.

No studies on the effects on human fertility have been conducted (please refer to Section 5.3).



No studies on the effects on the ability to drive and use machines have been performed. However,

patients should be advised that they may experience undesirable effects such as accommodation

disorder or dizziness during treatment with BUSCOPAN injection. Therefore, caution should be

recommended when driving a car or operating machinery. If patients experience accommodation

disorder or dizziness, they should avoid potentially hazardous tasks such as driving or operating

Nervous system disorders

Very rarely in the national post marketing surveillance data base, there have been isolated reports

following parenteral administration of coma, hallucinations, dystonia, confusion, agitation and

dizziness from which the patient recovered after drug withdrawal and appropriate treatment. In very

rare cases, dyspnoea has been reported.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicine is important. It allows

continued monitoring of the benefit/risk balance of the medicine. Healthcare professionals are asked

to report any suspected adverse reactions https://nzphvc.otago.ac.nz/reporting/.




Serious signs of poisoning following acute overdosage have not been observed in man. In case of

overdose, anticholinergic symptoms such as urinary retention, dry mouth, reddening of skin,

tachycardia, inhibition of gastrointestinal motility, and transient visual disturbances may occur.


In the case of oral poisoning, gastric lavage with activated charcoal should be followed by

magnesium sulphate (15%). Symptoms of BUSCOPAN and BUSCOPAN FORTE overdosage

respond to parasympathomimetics. For patients with glaucoma, urgent ophthalmological advice

should be sought and pilocarpine should be given locally. If necessary, parasympathomimetics

should be administered, e.g. neostigmine 0.5-2.5 mg i.m. or i.v. Cardiovascular complications as a

result of using this medicine should be treated according to usual therapeutic principles. In case of

respiratory paralysis: intubation, artificial respiration should be considered. Catheterisation may be

required for urinary retention. In addition, appropriate supportive measures should be used as

gastrointestinal, biliary and urinary tracts. As a quaternary ammonium derivative, hyoscine-N-

butylbromide does not enter the central nervous system. Therefore, anticholinergic side effects at the

central nervous system do not occur. Peripheral anticholinergic effects result from a ganglion-

blocking action within the visceral wall as well as from anti-muscarinic activity.




As a quaternary ammonium compound, hyoscine-N-butylbromide is highly polar and hence only

partially absorbed following oral (8%) administration. After oral administration of single doses of

hyoscine butylbromide in the range of 20 to 400 mg, mean peak plasma concentrations between

0.11 ng/mL and 2.04 ng/mL were found at approximately 2 hours. In the same dose range, the

observed mean AUC0-tz-values varied from 0.37 to 10.7 ng h/mL. The median absolute

bioavailabilities of different dosage forms, i.e. coated tablets, suppositoires and oral solution,

containing 100 mg of hyoscine butylbromide each were found to be less than 1%.


After intravenous administration hyoscine butylbromide is rapidly distributed (t


= 4 min, t


29 min) into the tissues. The volume of distribution (V

) is 128 L (corresponding to approx. 1.7


Because of its high affinity for muscarinic receptors and nicotinic receptors, hyoscine butylbromide

is mainly distributed on muscle cells of the abdominal and pelvic area as well as in the intramural

ganglia of the abdominal organs. Plasma protein binding (albumin) of hyoscine butylbromide is

approximately 4.4%. Animal studies demonstrate that hyoscine butylbromide does not pass the

blood-brain barrier, but no clinical data to this effect is available. Hyoscine butylbromide (1 mM)

has been observed to interact with the choline transport (1.4 nM) in epithelial cells of human


in vitro

Metabolism and elimination

Following oral administration of single doses in the range of 100 to 400 mg, the terminal elimination

half-lives ranged from 6.2 to 10.6 hours. The main metabolic pathway is the hydrolytic cleavage of

the ester bond. Orally administered hyoscine butylbromide is excreted in the faeces and in the urine.

Studies in man show that 2 to 5% of radioactive doses is eliminated renally after oral, and 0.7 to

1.6% after rectal administration. Approximately 90% of recovered radioactivity can be found in the

faeces after oral administration. The urinary excretion of hyoscine butylbromide is less than 0.1% of

the dose. The mean apparent oral clearances after oral doses of 100 to 400 mg range from 881 to

1420 L/min, whereas the corresponding volumes of distribution for the same range vary from 6.13

to 11.3 x 105 L, probably due to very low systemic availability. The metabolites excreted via the

renal route bind poorly to the muscarinic receptors and are therefore not considered to contribute to

the effect of the hyoscine butylbromide

New Zealand Data Sheet

Buscopan & Buscopan Forte - Hyoscine butylbromide

Property of the Sanofi group - strictly confidential

Page 8


The half-life of the terminal elimination phase (t


) is approximately 5 hours. The total clearance is

1.2 L/min. Clinical studies with radiolabeled hyoscine butylbromide show that after intravenous

injection 42 to 61% of the radioactive dose is excreted renally and 28.3 to 37% faecally. The portion

of unchanged active ingredient excreted in the urine is approximately 50%. The metabolites

excreted via the renal route bind poorly to the muscarinic receptors and are therefore not considered

to contribute to the effect of the hyoscine butylbromide.



Acutely, hyoscine butylbromide has a low index of toxicity: oral LD50 values were 1000-3000

mg/kg in mice, 1040-3300 mg/kg in rats, and 600 mg/kg in dogs. Toxic signs were ataxia and

decreased muscle tone, additionally, in mice tremor and convulsions, in dogs mydriasis, dry mucous

membranes and tachycardia. Deaths from respiratory arrest occurred within 24 h. The intravenous

LD50 values of hyoscine butylbromide were 10-23 mg/kg in mice and 18 mg/kg in rats.

In repeated oral dose toxicity studies over 4 weeks, rats tolerated 500 mg/kg = "no observed adverse

effect level (NOAEL)". At 2000 mg/kg, by the action on parasympathetic ganglia of visceral area,

hyoscine butylbromide paralysed the gastrointestinal function resulting in obstipation. Eleven out of

50 rats died. Haematology and clinical chemistry results did not show dose-related variations.

Over 26 weeks, rats tolerated 200 mg/kg, while at 250 and 1000 mg/kg, the gastro-intestinal

function was depressed and deaths occurred. The NOAEL of the 39-week oral (capsule) dog study

was 30 mg/kg. The majority of clinical findings were attributable to acute effects of hyoscine

butylbromide at high dosages (200 mg/kg). No adverse histopathological findings were observed.

A repeated intravenous dose of 1 mg/kg was well tolerated by rats in a 4-week study. At 3 mg/kg,

convulsions occurred immediately after injection. Rats dosed with 9 mg/kg died from respiratory


Dogs treated intravenously over 5 weeks at 2 x 1, 2 x 3 and 2 x 9 mg/kg, showed a dose- dependent

mydriasis in all treated animals, in addition at 2 x 9 mg/kg, ataxia, salivation and decreased body

weight and food intake were observed. The solutions were locally well tolerated.

After repeated i.m. injection, the dose of 10 mg/kg was systemically well tolerated, but lesions of

muscles at the site of injection were distinctly increased if compared to control rats. At 60 and 120

mg/kg, mortality was high and local damages were dose-dependently increased.

Hyoscine butylbromide was neither embryotoxic nor teratogenic at oral doses of up to 200 mg/kg in

the diet (rat) and 200 mg/kg by gavage or 50 mg/kg s.c. (rabbit). Fertility was not impaired at doses

of up to 200 mg/kg p.o.

Like other cationic drugs, hyoscine butylbromide interacts with the choline transport system of

human placental epithelial cells in vitro. Transfer of hyoscine butylbromide to the foetal

compartment has not been proved.

Hyoscine butylbromide-suppositories were locally well tolerated.
