Vitofyllin is given to older dogs to improve their alertness and energy levels. It has a variety of effects in the body, including improving blood flow to the brain and to muscles, stimulating brain function and acting as an anti-oxidant against free radicals. The usual dose rate is 3-5mg per kilogram bodyweight, given twice daily. Vitofyllin is not absorbed well from the stomach if food is present, so it is much better to give on an empty stomach (or with a tiny morsel of food) and then to feed 30 minutes later.

Vivitonin 50 mg Tablets and Vivitonin 100 mg Tablets


Vivitonin 50 mg tablets are orange-yellow, film-coated tablets, quarter-scored on one side. Each tablet contains 50 mg of the xanthine derivative Propentofylline.

Vivitonin 100 mg tablets are orange-yellow, oblong film-coated tablets, half-scored on one side. Each tablet contains 100 mg of the xanthine derivative Propentofylline.


For improvement in dullness, lethargy and overall demeanour in dogs. Vivitonin is particularly useful in older dogs, where it may increase willingness to exercise and exercise tolerance.

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 inotropic 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 aminophylline.

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.

Vitofylin 50mg

ALAN RIDLEY (tagno1)

  • VioVet customer since 2015
  • From: Durham, United Kingdom

Since our Lakeland bitch was prescribed vitofylin for vestibular syndrome she seems to be drinking lots more water, is this a side effect?

  • Veterinary Advisor

Polydipsia (excessive water consumption) is not a known side effect of Vitofyllin. If your dog is drinking more than normal it would be best for your vet to take a look at her since there may be another underlying cause such as Cushings, Diabetes or Hyperthyroidism.
