Vomiting, diarrhoea and pruritus have been reported very rarely in spontaneous reports.

• – uncommon (more than 1 but less than 10 animals in 1,000 animals treated)

• – very rare (less than 1 animal in 10,000 animals treated, including isolated reports).

If you notice any side effects, even those not already listed in this package leaflet or you think that the medicine has not worked, please inform your veterinary surgeon.

• 7. TARGET SPECIES

Dogs.

• 8. DOSAGE FOR EACH SPECIES, ROUTE(S) AND METHOD OF ADMINISTRATION

This fixed combination product should only be used in dogs which require both active substances to be administered concomitantly at this fixed dose.

Oral use.

Cardalis chewable tablets should be administered to the dog once a day at a dosage of 0.25 mg/kg bodyweight benazepril hydrochloride (HCl) and 2 mg/kg bodyweight (bw) spironolactone, according to the following dosage table.

Bodyweight (kg) of dog	Strength and number of tablets to be administered:
	Cardalis 2.5 mg/20 mg chewable tablets	Cardalis 5 mg/40 mg chewable tablets	Cardalis 10 mg/80 mg chewable tablets
2.5 – 5	*/2

10 – 20		1
20 – 40			1
40 – 60			1 + */2
60 – 80			2

ADVICE ON CORRECT ADMINISTRATION

The tablets should be administered either mixed with a small amount of food offered to the dog just prior to the main meal, or with the meal itself. The tablets contain beef flavouring to improve palatability, and in a field study conducted in dogs with chronic degenerative valvular disease the tablets were voluntarily and fully consumed 92% of the time when offered either with or without food.

Not applicable.

• 11. SPECIAL STORAGE CONDITIONS

Keep out of the sight and reach of children.

This veterinary medicinal product does not require any special storage conditions.

Do not use this veterinary medicinal product after the expiry date which is stated on the bottle.

Shelf-life after first opening the bottle: 6 months.

• 12. SPECIAL WARNING(S)

Special precautions for use in animals

Kidney function and serum potassium levels should be evaluated before initiating the treatment with benazepril (hydrochloride) and spironolactone, especially in dogs which may suffer hypoadrenocor­ticism, hyperkalaemia or hyponatraemia. Unlike in humans, an increased incidence of hyperkalaemia was not observed in clinical trials performed in dogs with this combination. However, regular monitoring of renal function and serum potassium levels is recommended in dogs with renal impairment, as they may have an increased risk of hyperkalaemia during treatment with this product.

Due to the antiandrogenic effect of spironolactone, it is not recommended to administer the veterinary medicinal product to growing dogs.

Reversible prostatic atrophy in entire male dogs treated with spironolactone was noted in a Target Animal Safety study at the recommended dose.

The product should be used with caution in dogs with hepatic dysfunction because it may alter the extensive biotransformation of spironolactone in liver.

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

People with known hypersensitivity to spironolactone or benazepril should avoid contact with the product.

Pregnant women should take special care to avoid accidental oral exposure because ACE inhibitors have been found to affect the unborn child during pregnancy in humans.

Accidental ingestion, particularly by children, may lead to adverse events such as drowsiness, nausea and vomiting and diarrhoea, and skin rashes.

In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the label to the physician.

Wash hands after use.

Pregnancy and lactation

Do not use during pregnancy and lactation. Embryotoxic effects (foetal urinary tract malformation) were seen in trials of benazepril (as hydrochloride) with laboratory animals (rats) at maternally nontoxic doses.

Interaction with other medicinal products and other forms of interaction

Furosemide has been used together with this combination of benazepril (hydrochloride) and spironolactone in dogs with heart failure without any clinical evidence of adverse interactions. The concomitant administration of the product with other anti-hypertensive agents (e.g. calcium channel blockers, p-blockers or diuretics), anaesthetics or sedatives may potentially lead to additive hypotensive effects.

The concomitant administration of this veterinary medicinal product with other potassium-sparing treatments (such as B-blockers, calcium channels blockers, angiotensin receptor blockers) may potentially lead to hyperkalaemia (see section „Special precautions for use in animals“).

The concomitant use of NSAIDs with this veterinary medicinal product may reduce its antihypertensive effect, its natriuretic effect and increase the level of serum potassium. Therefore, dogs treated concomitantly with an NSAID should be closely monitored and correctly hydrated.

The administration of deoxycorticosterone with the product may lead to a moderate reduction of the natriuretic effects (reduction of urinary sodium excretion) of spironolactone.

Spironolactone decreases digoxin elimination and hence raises digoxin plasma concentration. As the therapeutic index for digoxin is very narrow, it is advisable to monitor closely dogs receiving both digoxin and a combination of benazepril (hydrochloride) and spironolactone.

Spironolactone may cause both induction and inhibition of cytochrome P450 enzymes and could affect the metabolism of other substances utilizing these metabolic pathways. Therefore, the product should be used with caution with other veterinary medicinal products which induce, inhibit, or which are metabolised by these enzymes.

Overdose (symptoms, emergency procedures, antidotes)

After administration of up to 10 times the recommended dose (2.5 mg/kg bw benazepril hydrochloride, 20 mg/kg spironolactone) to healthy dogs, dose dependent adverse effects were noted, see section „Adverse reactions“.

Daily overdoses to healthy dogs, i.e. 6 times (1.5 mg/kg bw benazepril hydrochloride, 12 mg/kg bw spironolactone) and 10 times (2.5 mg/kg bw benazepril hydrochloride, 20 mg/kg bw spironolactone) the recommended dose, led to a slight dose related decrease in red cell mass. However, this very slight decrease was transient, the red cell mass remained within the normal range, and the finding was not considered to be of clinical importance.

A dose related but moderate compensatory physiological hypertrophy of zona glomerulosa of the adrenal glands was also observed at doses of 3 times and greater of the recommended dose. This hypertrophy does not seem to be linked to any pathology and was observed to be reversible upon discontinuation of the treatment.

In case of the accidental ingestion by a dog of many Cardalis chewable tablets, there is no specific antidote or treatment. It is therefore recommended to induce vomiting, and then carry out gastric lavage (depending on the risk assessment) and monitor electrolytes. Symptomatic treatment, e.g., fluid therapy, should also be provided.
