with an increase in left ventricular end-systolic and end-diastolic diameter) in
Doberman Pinschers following echocardiographic diagnosis of cardiac disease.
To ensure a correct dosage, the bodyweight should be determined as accurately as
possible.
A dosage range of 0.2 mg to 0.6 mg pimobendan/kg bodyweight, divided into two
daily doses, should be respected. The preferrable daily dose is 0.5 mg
pimobendan/kg bodyweight divided into two daily doses given approximately
12 hours apart (i.e., 0.25 mg pimobendan/kg bodyweight equivalent to 0.17 ml of the
veterinary medicinal product twice daily).
The solution should be given using the measuring syringe provided in the package.
The syringe has a kg bodyweight scale with 0.5 kg increments up to a bodyweight of
12 kg and fits onto the bottle. Each 1 kg increment corresponds to 0.25 mg
pimonbendan. The total bodyweight of the animal should be used for each
administration. For example, for a 6 kg dog, the veterinary medicinal product should
be drawn up to the 6 kg mark on the syringe for each administration (this equates to
a 0.25 mg pimobendan/kg bodyweight dose per administration). Do not exceed the
recommended dosage.
Each dose should be given directly into the mouth on an empty stomach,
approximately one hour before feeding. After administration, close the bottle tightly
using the cap. Clean the outside of the syringe by wiping with a clean, dry cloth or
tissue after each use. The contaminated tissue should be immediately disposed of.
If the syringe clogs, rinse without removing the plunger by using water and wiping the
outside of the syringe dry with a clean cloth or tissue. To avoid contamination, use
the provided syringe only to administer this oral solution. The used syringe should be
stored with the veterinary medicinal product in the original carton.
Pimobendan may also be used in combination with a diuretic e.g., furosemide.
Advice on correct administration
The veterinary medicinal product consists of a bottle
sealed with a child-resistant cap A, a second child-resistant
cap with integrated plug-in adapter B and a measuring
dosing syringe with a kg-bodyweight scale C.
Do not shake the bottle prior to use (this avoids foaming).
Open the bottle in an upright position by pressing down on
the child-resistant cap A and simultaneously turning the
cap anticlockwise. Discard the white cap A.
Tightly close the bottle using the cap B and turn
simultaneously the cap clockwise. The cap B contains an
integrated plug-in adapter which should automatically
attach to the bottle A. Ensure the cap is tightly closed to
appropriately insert plug.
Remove the cap B from the bottle by pressing down on the
child-resistant cap and simultaneously turning the cap
anticlockwise and gently push the end of the dosing
syringe
Turn the bottle and syringe upside down.
Pull the plunger out and fill the dosing syringe to the dose
prescribed by your veterinarian.
Turn the bottle upright and remove the dosing syringe from
the bottle Close the bottle with cap B.
Put the end of the doing syringe C into your dog´s mouth
and push the plunger to give the prescribed dose.

excipients.

Special precautions for safe use in the target species:
In dogs with existing diabetes mellitus, blood glucose should be tested regularly
during treatment with pimobendan.
For use in the preclinical stage of dilated cardiomyopathy (asymptomatic with an
increase in left ventricular end-systolic and end-diastolic diameter), a diagnosis
should be made by means of a comprehensive cardiac examination (incl.
echocardiographic examination and possibly Holter monitoring).
Monitoring of cardiac function and morphology is recommended in animals treated
with pimobendan.
