Actikor 5 mg Film-coated Tablets for Dogs


QUALITATIVE AND QUANTITATIVE COMPOSITION


Each film-coated tablet contains:

Active substance:

Benazepril 4.6 mg (equivalent to 5 mg of benazepril hydrochloride).


Excipient(s):

For a full list of excipients, see section 6.1.


PHARMACEUTICAL FORM


Film-coated tablets


Yellow coloured, oval, biconvex, film-coated tablets with a breakline on one side and plain on the other side.


The tablets can be divided into equal halves.


4. CLINICAL PARTICULARS


4.1 Target species


Dog


4.2 Indications for use, specifying the target species


Dogs weighing more than 5 kg:


Treatment of congestive heart failure associated with, in particular, dilated cardiomyopathy or mitral insufficiency


4.3 Contraindications


Do not use in any dog that has evidence of cardiac output failure for example due to aortic stenosis.

Do not use in cases of hypersensitivity to benazepril or to any other ACE inhibitors or to any of the excipient(s).

For usein pregnant, lactating and breeding animals, please refer Section 4.7.


4.4 Special warnings for each target species


None


4.5 Special precautions for use


Special precautions for use in animals


No evidence of renal toxicity has been observed in dogs during clinical trials. As is routine in cases of renal insufficiency, it is recommended to monitor plasma creatinine and urea during therapy.

Special precautions to be taken by the person administering the veterinary medicinal product to animals



4.6 Adverse reactions (frequency and seriousness)


At the start of the treatment, a decrease of the blood pressure and a transient increase of plasma concentrations of creatinine may occur. In rare cases fatigue or drowsiness may be observed and transient signs of hypotension, such as lethargy and ataxia may occur.


4.7 Use during pregnancy, lactation or lay


Studies in laboratory animals (rats) have shown embryotoxic effects of benazepril at non-maternotoxic doses (malformations of the foetal urinary system). Benazepril administered to cats at a daily dose of 10 mg / kg for 52 weeks resulted in the reduction of ovary / oviduct weights. In humans ACE inhibitors have been found to be teratogenic during pregnancy.

Do not use in breeding, pregnant or lactating dogs as the safety of the product in these animals has not been tested.


4.8 Interaction with other medicinal products and other forms of interaction


None known in dogs


In dogs with heart failure, Benazepril hydrochloride has been given in combination with digoxin, diuretics and anti-arrythmic drugs without demonstrable adverse interactions. In human, the combination of ACE inhibitors and NSAIDs can lead to reduced anti-hypertensive efficacy or impaired renal function. The combination of Actikor tablet and other anti-hypertensive agents (e.g. calcium channel blockers, -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 closely monitored 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 benazepril in combination with a potassium sparing diuretic as life threatening reactions are a possibility.


4.9 Amounts to be administered and administration route


For oral use


The therapeutic oral dose is 0.25 mg benazepril hydrochloride / kg body weight once daily, with or without food according to the following dose regime:


Dogs weighing 5-10 kg: ½ Actikor 5 mg tablet

Dogs weighing 11-20 kg: 1 Actikor 5 mg tablet.

Dogs weighing 21-40 kg: ½ Actikor 20 mg tablet

Dogs weighing 41-80 kg: 1 Actikor 20 mg tablet.


The dose may be doubled (0.5 mg benazepril hydrochloride / kg body weight) still administered once daily, if judged clinically necessary and advised by the veterinary surgeon.


In case of using halved tablets: Return any remaining half tablet to the opened blister pocket and store it below 30°C. Use the remaining half tablet for the next administration.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary


In normal dogs, overdosage up to 200-fold of benazepril hydrochloride was asymptomatic. Transient reversible hypotension may occur in cases of accidental overdosage. Therapy should consist of intravenous infusion of warm isotonic saline.


4.11 Withdrawal period(s)


Not applicable.


5. PHARMACOLOGICAL PROPERTIES


Pharmaceutical group:Cardiovascular system, agents acting on the renin- angiotensin 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 angiotensin converting enzyme (ACE), thus preventing the conversion of inactive angiotensin I to active angiotensin II. Therefore, it blocks effects mediated by angiotensin II, including vasoconstriction of both arteries and veins, retention of sodium and water by the kidney.


The product causes long-lasting inhibition of plasma ACE activity with more than 95% inhibition at peak effect and significant activity (>80%) persisting 24 hours after dosing.


5.2 Pharmacokinetic particulars


After oral administration of benazepril hydrochloride, peak levels of benazepril are attained rapidly (tmax 0.5 h) and decline quickly as the drug is partially metabolised by liver enzymes to benazeprilat. Unchanged benazepril and hydrophilic metabolites account for the remainder. Peak benazeprilat concentrations (Cmax of 26.7 ng/ml after a dose of 0.5 mg/kg benazepril hydrochloride) are achieved with a Tmax of 1.25h. The systemic bioavailability is incomplete (~13%) due to incomplete absorption (38%) and first pass metabolism.

Benazeprilat concentrations decline biphasically: the initial fast phase (t1/2=1.7h) represents elimination of free drug, while the terminal phase (t1/2=19h) reflects the release of benazeprilat that was bound to ACE, mainly in the tissues. Benazepril and benazeprilat are extensively bound to plasma proteins, 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 Actikor tablet 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 via the biliary (54%) and urinary (46%) routes.The clearance of benazeprilat is not affected in dogs with impaired renal function and therefore no adjustment of Actikor tablet dose is required in cases of renal insufficiency.
