(hyoscine butylbromide)
Trade name of the medicinal product
BUSCOPAN Ampoules 20 mg/ml solution for injection.
Qualitative and quantitative composition
Each 1 ml ampoule contains 20 mg hyoscine butylbromide. For
excipients, see List of excipients
Pharmaceutical form
Solution for injection. A colourless or almost colourless, clear
Clinical particulars
Therapeutic indications
BUSCOPAN Ampoules are indicated in acute spasm, as in renal or
biliary colic, in radiology for differential diagnosis of obstruction
and to reduce spasm and pain in pyelography, and in other
diagnostic procedures where spasm may be a problem, e.g. gastroduodenal endoscopy.
Posology and method of administration
Adults: One ampoule (20 mg) intramuscularly or intravenously,
repeated after half an hour if necessary. Intravenous injection
should be performed ‘slowly’, (in rare cases a marked drop in blood
pressure and even shock may be produced by BUSCOPAN). When
used in endoscopy this dose may need to be repeated more frequently.
Maximum daily dose of 100 mg.
Special populations
No specific information on the use of this product in the elderly is
available. Clinical trials have included patients over 65 years and
no adverse reactions specific to this age group have been reported.
Paediatric population
Not recommended for children
BUSCOPAN Ampoules should not be taken on a continuous daily
basis or for extended periods without investigating the cause of
abdominal pain.
Diluent: BUSCOPAN injection solution may be diluted with
dextrose or with sodium chloride 0.9% injection solutions.
BUSCOPAN Ampoules should not be administered to patients with
myasthenia gravis, megacolon, narrow angle glaucoma, tachycardia,
prostatic enlargement with urinary retention, mechanical stenoses
in the region of the gastrointestinal tract or paralytic ileus.
BUSCOPAN should not be used in patients who have demonstrated
prior hypersensitivity to hyoscine butylbromide or any other
component of the product.
BUSCOPAN Ampoules should not be given by intramuscular
injection to patients being treated with anticoagulant drugs since
intramuscular haematoma may occur.
Special warnings and precautions for use
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, appropriate diagnostic
measures are needed to investigate the etiology of the symptoms.
BUSCOPAN Ampoules 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.

Because of the possibility that anticholinergics may reduce
sweating, BUSCOPAN should be administered with caution to
patients with pyrexia.
Elevation of intraocular pressure may be produced by the
administration of anticholinergic agents such as BUSCOPAN in
patients with undiagnosed and therefore untreated narrow angle
glaucoma. Therefore, patients should seek urgent
ophthalmological advice in case they should develop a painful, red
eye with loss of vision after the injection of 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.
Interaction with other medicinal products and other forms
of interaction
The anticholinergic effect of drugs such as tri- and tetracyclic
antidepressants, antihistamines, quinidine, amantadine,
antipsychotics (e.g. phenothiazines, butyrophenones),
disopyramide and other anticholinergics (e.g. tiotropium,
ipratropium, atropine-like compounds) may be intensified by
BUSCOPAN. The tachycardic effects of beta-adrenergic agents may
be enhanced by BUSCOPAN.
Concomitant treatment with dopamine antagonists such as
metoclopramide may result in diminution of the effects of both
drugs on the gastrointestinal tract.
Fertility, pregnancy and lactation
There are limited data from the use of hyoscine butylbromide in
pregnant women. Animal studies are insufficient with respect to
reproductive toxicity (see Pre-clinical safety data). As a
precautionary measure BUSCOPAN is not recommended during
There is insufficient information on the excretion of hyoscine
butylbromide and its metabolites in human milk. A risk to the
breastfeeding child cannot be excluded. Use of BUSCOPAN during
breastfeeding is not recommended
No studies on the effects on human fertility have been conducted.
Effects on ability to drive and use machines
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 Ampoules.
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 machinery.
Undesirable effects
Many of the listed undesirable effects can be assigned to the
anticholinergic properties of BUSCOPAN. Adverse events have
been ranked under headings of frequency using the following
Very common

Injection site pain, particularly after intramuscular use, occurs.
Hyoscine butylbromide, the active ingredient of BUSCOPAN, due to
its chemical structure as a quaternary ammonium derivate, is not
expected to enter the central nervous system. Hyoscine
butylbromide does not readily pass the blood-brain barrier.
However, it cannot totally be ruled out that under certain
circumstances psychiatric disorders (e.g. confusion) may also
occur after administration of BUSCOPAN.
*This adverse reaction has been observed in post-marketing
experience. With 95% certainty, the frequency category is not
greater than common, but might be lower. A precise frequency
estimation is not possible as the adverse drug reaction did not
occur in a clinical trial database of 185 patients.
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

Pharmacokinetic properties
Absorption and distribution
After intravenous administration hyoscine butylbromide is rapidly
distributed (t½α = 4 min, t½β = 29 min) into the tissues. The
volume of distribution (Vss) is 128 L (corresponding to approx.
1.7 L/kg). 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 placenta in vitro.
Metabolism and elimination
The main metabolic pathway is the hydrolytic cleavage of the ester
bond. The half-life of the terminal elimination phase (t½γ) 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.
Paediatric population
No particular pharmacokinetic studies concerning hyoscine
butylbromide have been performed in children.
Pre-clinical safety data
In limited reproductive toxicity studies hyoscine butylbromide
showed no evidence of teratogenicity in rats at 200 mg/kg in the
diet or in rabbits at 200 mg/kg by oral gavage or 50 mg/kg by
subcutaneous injection. Fertility in the rat was not impaired at
doses up to 200 mg/kg in the diet.

Once opened, use immediately and discard any unused contents.

Symptoms: Serious signs of poisoning following acute
overdosage have not been observed in man. In the case of
overdosage, anticholinergic symptoms such as urinary retention,
dry mouth, reddening of the skin, tachycardia, inhibition of
gastrointestinal motility and transient visual disturbances may
occur, and Cheynes-Stokes respiration has been reported.

Special precautions for storage
Store below 30˚C
Store in the outer carton in order to protect from light.

Therapy: Symptoms of BUSCOPAN overdosage respond to
parasympathomimetics. For patients with glaucoma, pilocarpine
should be given locally. Cardiovascular complications should be
treated according to usual therapeutic principles. In case of
respiratory paralysis, intubation and artificial respiration.
Catheterisation may be required for urinary retention.
