4. CLINICAL PARTICULARS
4.1 Target Species
Cattle (adult), horses and dogs.

and as a diagnostic aid in more severe equine colics.
For the control of diarrhoea in cattle, horses and dogs particularly
when pain or abdominal discomfort is present.

4.4 Special warnings for each target species
4.5 Special Precautions for Use
i. Special precautions for use in animals
ii. Special Precautions to be taken by the person administering the product to animals
Take care to avoid self-injection. In a very small number of people, metamizole can cause reversible, but potentially serious agranulocytosis and other reactions such as skin allergy.
Avoid use of the product if you are known to be sensitive to pyrazolones, or are sensitive to aspirin.
Wash any splashes from the skin.
If accidental self-injection occurs, seek medical advice and show the Doctor the product packaging.
4.6 Adverse reactions (frequency and seriousness)
In horses, a slight transient increase in heart rate may be observed due to the parasympatholytic activity of butylscopolaminiumbromide (hyoscine butylbromide).
4.7 Use during Pregnancy, lactation or lay
Studies in laboratory animals (rabbit, rat) have not produced any evidence of a teratogenic effect. No information on use during pregnancy in the target species is available and therefore this product should not be used.
4.8 Interaction with other medicinal products and other forms of interaction.
The effects of metamizole and/or butylscopolamine bromide may be potentiated by concurrent use of other anticholinergic or analgesic drugs.
4.9 Amounts to be administered and administration route
Use aseptic techniques.
Horses: 5 ml Buscopan Compositum per 100 kg body weight by intravenous injection only.
Adult Cattle: 5 ml Buscopan Compositum per 100 kg body weight by intravenous or intramuscular injection
Dogs; 0.1 ml Buscopan Compositum per kg body weight by intravenous or intramuscular injection
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
The acute toxicity of both compounds is very low. In studies with rats the symptoms were non-specific and included ataxia, mydriasis, tachycardia, prostration, convulsions, coma and respiratory signs.
Symptomatic treatment should be initiated in case of overdosage.
4.11 Withdrawal Periods
Meat and Offal:
Horses - 12 days

5. PHARMACOLOGICAL PROPERTIES
ATC Vet Code:QA03DB04 : antispasmodic in combination with analgesic
5.1 Pharmacodynamic properties
Butylscopolamine bromide is a spasmolytic agent with particular activity on the smooth muscle of the digestive and urinary systems. It antagonises the actions of acetylcholine at the muscarinic receptor and also has some activity at nicotinic receptors. Its pharmacological profile is similar to atropine, the main member of this class.
5.2 Pharmacokinetic properties
The quarternary ammonium structure confers poor absorption after oral administration and prevents penetration of the central nervous system after parenteral administration. 17-24% is plasma protein bound and plasma elimination half-life is 2-3 hours. It is excreted mostly unchanged - about 54% via the kidneys in urine after parenteral administration. After oral administration, only around 1% is excreted in urine.
Metamizole is a non-steroidal anti-inflammatory drug of the pyrazolone group and also has analgesic and anti-pyretic effects. It is rapidly absorbed with absolute bioavailability of nearly 100%. The primary metabolite in plasma and urine is 4-methyl-aminoantipyrine (MAA), which is pharmacologically active with a plasma half life of around 6 hours. Other metabolites are present in smaller quantities. The metabolites are bound (to various degrees) to plasma proteins, with 56% MAA bound. Excretion occurs mainly via the kidney, with 50-70% of the dose eliminated in urine, depending on species.
