Target species
Dogs
Indications for use
Treatment of congestive heart failure
Contra-indications
Do not use in case of hypersensitivity to the active substance or to any of the excipients.
Do not use in cases of hypotension, hypovolaemia, hyponatraemia or acute renal failure.
Do not use in cases of cardiac output failure due to aortic or pulmonary stenosis.
Do not use during pregnancy or lactation (see section Use during pregnancy, lactation or lay).
Special precautions for use
Special precautions for use in animals
No evidence of renal toxicity of the veterinary medicinal product has been observed during clinical trials, however, as is routine in cases of chronic kidney disease, it is recommended to monitor plasma creatinine, urea and erythrocyte counts during therapy.
The safety and efficacy of the product has not been examined in dogs weighing less than 2.5 kg
Special precautions to be taken by the person administering the product to animals
Wash hands after use.
In case of accidental oral ingestion, seek medical advice immediately and show the label or the package leaflet to the physician.
Pregnant women should take special care to avoid accidental oral exposure, because angiotensin converting enzyme (ACE) inhibitors have been found to affect the unborn child during pregnancy in humans.
Adverse reactions (frequency and seriousness)
In double-blind clinical trials in dogs with congestive heart failure, the product was well tolerated with an incidence of adverse reactions lower than observed in placebo-treated dogs.
A small number of dogs may exhibit transient vomiting, incoordination or signs of fatigue.
In dogs with chronic kidney disease, the product may increase plasma creatinine concentrations at the start of therapy. A moderate increase in plasma creatinine concentrations following administration of ACE inhibitors is compatible with the reduction in glomerular hypertension induced by these agents, and is therefore not necessarily a reason to stop therapy in the absence of other signs.
Use during pregnancy, lactation or lay
Do not use during pregnancy or lactation. The safety of the product has not been established in breeding, pregnant or lactating dogs. In cats benazepril reduced the weight of the ovaries and the ovarian ducts when given at a daily dose of 10 mg/kg for 52 weeks. Embryotoxic effects (foetal urinary tract malformation) were seen in trials with laboratory animals (rats) at maternally nontoxic doses.
Interaction with other medicinal products and other forms of interaction
In dogs with congestive heart failure, this product has been given in combination with digoxin, diuretics, pimobendan and anti-arrhythmic veterinary medicinal products without demonstrable adverse interactions.
In humans, the association of ACE inhibitors and Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) can lead to reduced anti-hypertensive efficacy or impaired renal function. The combination of this product and other anti-hypertensive agents (e.g. calcium channel blockers, β-blockers or diuretics), anaesthetics or sedatives may lead to additive hypotensive effects. Therefore, concurrent use of NSAIDs or other medications with a hypotensive effect should be considered with care. Renal function and signs of hypotension (lethargy, weakness etc) should be monitored closely and treated as necessary.
Interactions with potassium preserving diuretics like spironolactone, triamterene or amiloride cannot be ruled out. It is recommended to monitor plasma potassium levels when using this product in combination with a potassium sparing diuretic because of the risk of hyperkalaemia.
Amounts to be administered and administration route
The product should be given orally once daily, with or without food. The duration of treatment is unlimited.
Dogs: The product should be administered orally at a minimum dose of 0.25 mg (range 0.25-0.5) benazepril hydrochloride/kg body weight once daily, according to the following tables:
Nelio 5mg:
Weight of Dog (kg) | Standard dose | Double dose |
2.5 - 5 | 1⁄4 tablet | ½ tablet |
>5 - 10 | ½ tablet | 1 tablet |
>10 - 15 | 3⁄4 tablet | 1 ½ tablets |
>15 - 20 | 1 tablet | 2 tablets |
Nelio 20mg:
Weight of dog (kg) | Standard dose | Double dose |
>20 - 40 | ½ tablet | 1 tablet |
>40 - 60 | 3⁄4 tablet | 1 ½ tablets |
>60 - 80 | 1 tablet | 2 tablets |
The dose may be doubled, still administered once daily, to a minimum dose of 0.5 mg/kg (range 0.5-1.0), if judged clinically necessary and advised by the veterinary surgeon.
In case of use of quarters or half tablets: Put the remaining quantity of the tablet back into the blister pocket and use for the next administration.
The tablets are flavoured and may be taken spontaneously by dogs, but can also be administered directly into the dog’s mouth or be given with food if necessary.
Instruction on how to divide the tablet: Put the tablet on an even surface, with its scored side facing down (convex face up). With the tip of the forefinger, exert slight vertical pressure on the middle of the tablet to break it along its width into halves. Then, in order to obtain quarters, exert slight pressure on the middle of one half with the forefinger to break it into two parts.
Overdose (symptoms, emergency procedures, antidotes), if necessary
The product reduced erythrocyte counts in normal dogs when dosed at 150 mg/kg body weight once daily for 12 months, but this effect was not observed at the recommended dose during clinical trials in dogs.
Transient reversible hypotension may occur in case of accidental overdose. Therapy should consist of intravenous infusion with warm isotonic saline.
