4. CLINICAL PARTICULARS OF NELIO 20 mg
4.1 Target species
4.2 Indications for use,specifying the target species
- Treatment of congestive heart failure
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 (section 4.7).
4.4 Special warnings for each target species
4.5 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
(ii) Special precautions to be taken by the person administering the veterinary medicinal 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.
4.6 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..
4.7 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.
4.8 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.
4.9 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.
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 table:
Weight of dog (kg): Standard dose; Double dose
>20-40: 0.5 tablet; 1 tablet
>40-60: 0.75 tablet; 1 ½ tablet
>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.
4.10 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.

5. PHARMACOLOGICAL PROPERTIES OF NELIO 20 mg
Pharmacotherapeutic group: Cardiovascular system, ACE Inhibitors, plain, Benazepril.
ATCvet code: QC09AA07
5.1 Pharmacodynamic properties
Benazepril hydrochloride is a prodrug hydrolysed in vivo to its active metabolite, benazeprilat.
Benazeprilat is a highly potent and selective inhibitor of ACE, thus preventing the conversion of inactive angiotensin I to active angiotensin II and thereby also reducing synthesis of aldosterone. Therefore, it blocks effects mediated by angiotensin II and aldosterone, including vasoconstriction of both arteries and veins, retention of sodium and water by the kidney and remodelling effects (including pathological cardiac hypertrophy and degenerative renal changes).
The product causes long-lasting inhibition of plasma ACE activity in dogs, with more than 95% inhibition at peak effect and significant activity (>80%) persisting 24 hours after dosing.
The product reduces the blood pressure and volume load on the heart in dogs with congestive heart failure.
5.2 Pharmacokinetic particulars
After oral administration of benazepril hydrochloride, peak levels of benazepril are attained rapidly (Tmax 0.5 hour) and decline quickly as the active substance is partially metabolised by liver enzymes to benazeprilat. The systemic bioavailability is incomplete (~13%) due to incomplete absorption (38%) and first pass metabolism.
Peak benazeprilat concentrations (Cmax of 30 ng/ml after a dose of 0.5 mg/kg benazepril hydrochloride) are achieved with a Tmax of 1.5 hours.
Benazeprilat concentrations decline biphasically: the initial fast phase (t1/2=1.7 hours) represents elimination of free drug, while the terminal phase (t1/2=19 hours) reflects the release of benazeprilat that was bound to ACE, mainly in the tissues.
Benazepril and benazeprilat are extensively bound to plasma proteins (85-90%), and in tissues are found mainly in the liver and kidney.
There is no significant difference in the pharmacokinetics of benazeprilat when benazepril hydrochloride is administered to fed or fasted dogs. Repeated administration of the product leads to slight bioaccumulation of benazeprilat (R=1.47 with 0.5 mg/kg), steady state being achieved within a few days (4 days).
Benazeprilat is excreted 54% via the biliary and 46% via the urinary route. The clearance of benazeprilat is not affected in dogs with impaired renal function and therefore no adjustment of the product dose is required in cases of renal insufficiency.
