Pharmacological properties

Pharmacotherapeutic group: peripheral vasodilator; purine derivatives; propentofylline ATCvet Code: QC04AD90

5.1 Pharmacodynamic properties

Propentofylline has been shown to increase blood flow, particularly of the heart and skeletal muscle. It also increases the blood flow of the brain and therefore its oxygen supply, without increasing the brain's glucose demand. It has a modest positive chronotropic effect and a marked positive ionotropic effect. In addition, it has been shown to have an anti-arrhythmic effect in dogs with myocardial ischemia and a bronchodilator action equivalent to that of aminofylline.

Propentofylline inhibits platelet aggregation and improves the flow properties of erythrocytes.

It has a direct effect on the heart and reduces peripheral vascular resistance thereby lowering cardiac load.

Propentofylline may increase willingness to exercise and exercise tolerance, particularly in older dogs.

5.2 Pharmacokinetic particulars

After oral administration propentofylline is fast and completely absorbed and quickly distributed in the tissues. Given orally to dogs, maximum plasma levels are reached already after 15 minutes.

The half-life is about 30 minutes and the bioavailability for the parent substance amounts to about 30%. There are a number of effective metabolites and the biotransformation takes place mainly in the liver. Propentofylline is excreted in the form of its metabolites between 80-90% via the kidneys. The rest is eliminated with the faeces. There is no accumulation.

Dosage

The basic dosage is 6-10 mg propentofylline/kg bodyweight daily, divided into two 3-5 mg/kg doses as follows:

To ensure administration of the correct dose, the body weight of the animal should be determined before treatment.

More accurate dosing may be achieved by using either quarters of the 100mg tablets or a combination of 100 mg and 50 mg tablets. Dogs of less than 20 kg can be given Vitofyllin 50 mg film-coated tablets for dogs.

The tablets can be administered directly onto the back of the dog's tongue or can be mixed in a small ball of food and should be administered at least 30 minutes before feeding.
