Pharmacological properties

Pharmacotherapeutic group: Endectocides

ATC vet Code : QP54AB51 (milbemycin oxime, combinations)

5.1 Pharmacodynamic properties

Milbemycin oxime belongs to the group of macrocyclic lactones, isolated from the fermentation of Streptomyces hygroscopicus var. aureolacrimosus. It is active against mites, against larval and adult stages of nematodes as well as against larvae of Dirofilaria immitis.

The activity of milbemycin is related to its action on invertebrate neurotransmission: Milbemycin oxime, like avermectins and other milbemycins, increases nematode and insect membrane permeability to chloride ions via glutamate-gated chloride ion channels (related to vertebrate GABAA and glycine receptors). This leads to hyperpolarisation of the neuromuscular membrane and flaccid paralysis and death of the parasite.

Praziquantel is an acylated pyrazino-isoquinoline derivative. Praziquantel is active against cestodes and trematodes. It modifies the permeability for calcium (influx of Ca2+) in the membranes of the parasite inducing an imbalance in the membrane structures, leading to membrane depolarisation and almost instantaneous contraction of the musculature (tetany), rapid vacuolization of the syncytial tegument and subsequent tegumental disintegration (blebbing), resulting in easier expulsion from the gastrointestinal tract or death of the parasite.

5.2 Pharmacokinetic particulars

After oral administration of praziquantel in the dog, peak serum levels of parent are rapidly attained (Tmax approximately 0.5-4 hours) and decline quickly (t1/2 approximately 1.5 hours). There is a substantial hepatic first-pass effect, with very rapid and almost complete hepatic biotransformation, principally to monohydroxylated (also some di- and tri-hydroxylated) derivatives, which are mostly glucuronide and/or sulfate conjugated before excretion. Plasma binding is about 80%. Excretion is fast and complete (about 90% in 2 days); the principal route of elimination is renal.

After oral administration of milbemycin oxime in dogs, peak plasma levels occur at about 2-4 hours, and decline with a half-life of the unmetabolised milbemycin oxime of 1-4 days. Bioavailability is about 80%.

In the rat, metabolism appears to be complete although slow, since unchanged milbemycin oxime has not been found in urine or feces. Main metabolites in the rat are monohydroxylated derivatives, attributable to hepatic biotransformation. In addition to relatively high liver concentrations, there is some concentration in fat, reflecting its lipophilicity.

Indications

In dogs: treatment of mixed infections by adult cestodes and nematodes of the following species susceptible to praziquantel and milbemycin oxime:

- Cestodes:

Dipylidium caninum Taenia spp.

Echinococcus spp.

Mesocestoides spp.

- Nematodes:

Ancylostoma caninum Toxocara canis Toxascaris leonina Trichuris vulpis Crenosoma vulpis (Reduction of the level of infection) Angiostrongylus vasorum (Reduction of the level of infection by immature adult (L5) and adult parasite stages; see specific treatment and prevention disease schedules under SPC point “4.9 Amounts to be administered and administration route”) Thelazia callipaeda (see specific treatment schedule under section 4.9 “Amounts to be administered and administration route”)

The product can also be used in the prevention of heartworm disease (Dirofilaria immitis) if concomitant treatment against cestodes is indicated.

3

Dosage

Minimum recommended dose rate: 0.5 mg of milbemycin oxime and 5 mg of praziquantel per kg are given once orally.

The product should be administered with or after some food.

Depending on the bodyweight of the dog, the practical dosing is as follows:

In cases when heartworm disease prevention is used and at the same time treatment against tapeworm is required, Elanco Milbemycin - Praziquantel 12.5 mg/125 mg tablets for dogs can replace the monovalent product for the prevention of heartworm disease.

For treatment of Angiostrongylus vasorum infections , milbemycin oxime should be given four times at weekly intervals. It is recommended, where concomitant treatment against cestodes is indicated, to treat once with Elanco Milbemycin - Praziquantel 12.5 mg/125 mg tablets for dogs and continue with the monovalent product containing milbemycin oxime alone, for the remaining three weekly treatments.

In endemic areas administration of the product every four weeks will prevent angiostrongylosis by reducing immature adult (L5) and adult parasite burden, where concomitant treatment against cestodes is indicated.

For the treatment of Thelazia callipaeda, milbemycin oxime should be given in 2 treatments, seven days apart. Where concomitant treatment against cestodes is indicated, Elanco Milbemycin - Praziquantel 12.5 mg/125 mg tablets for dogs can replace the monovalent product containing milbemycin oxime alone.

Contraindications

Do not use in dogs weighing less than 5 kg

Do not use in cases of hypersensitivity to the active substances or to any of the excipients

See also section 4.5 "Special precautions for use"

3

Adverse reactions

In very rare occasions, hypersensitivity reactions, systemic signs (such as lethargy), neurological signs (such as muscle tremors and ataxia) and/or gastrointestinal signs (such as emesis, diarrhea, anorexia and drooling) have been observed in dogs after administration of the veterinary medicinal product”.

The frequency of adverse reactions is defined using the following convention:

- very common (more than 1 in 10 animals treated displaying adverse reaction(s))

- common (more than 1 but less than 10 animals in 100 animals treated)

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

- rare (more than 1 but less than 10 animals in 10,000 animals treated)

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

Warnings

Special precautions for use in animals

As per good veterinary practice, animals should be weighed to ensure accurate dosing.

Treatment of dogs with a high number of circulating microfilariae can sometimes lead to the appearance of hypersensitivity reactions, such as pale mucous membranes, vomiting, trembling, laboured breathing or excessive salivation. These reactions are associated with the release of proteins from dead or dying microfilariae and are not a direct toxic effect of the product. The use in dogs suffering from microfilaremia is thus not recommended.

In heartworm risk-areas, or in the case it is known that a dog has been travelling to and from heartworm risk regions, before using Elanco Milbemycin - Praziquantel 12.5 mg/125 mg tablets for dogs, a veterinary consultation is advised to exclude the presence of any concurrent infestation of Dirofilaria immitis. In the case of a positive diagnosis, adulticidal therapy is indicated before administering Elanco Milbemycin - Praziquantel 12.5 mg/125 mg tablets for dogs.

Echinococcosis represents a hazard for humans. In case of Echinococcosis, specific guidelines on the treatment and follow up and on the safeguard of persons have to be followed. Experts or institutes of parasitology should be consulted.

No studies have been performed with severely debilitated dogs or individuals with seriously compromised kidney or liver function. The product is not recommended for such animals or only according to a benefit/risk assessment by the responsible veterinarian.

In dogs less than 4 weeks old, tape worm infection is unusual. Treatment of animals less than 4 weeks old with a combination product may therefore not be necessary.

Parasite resistance to any particular class of anthelmintic may develop following frequent, repeated use of an anthelmintic of that class

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

Wash hands after use.

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

Interactions

The concurrent use of Elanco Milbemycin - Praziquantel 12.5 mg/125 mg tablets for dogs with selamectin is well tolerated. No interactions were observed when the recommended dose of the macrocyclic lactone selamectin was administered during treatment with Elanco Milbemycin - Praziquantel 12.5 mg/125 mg tablets for dogs at the recommended dose. In the absence of further studies, caution should be taken in the case of concurrent use of Elanco Milbemycin - Praziquantel 12.5 mg/125 mg tablets for dogs and other macrocyclic lactones. Also, no such studies have been performed with reproducing animals.

3

Overdose

No other signs than those observed at the recommended dose have been observed (see section 4.6).

3

Special warnings

It is recommended to treat all the animals living in the same household concomitantly. When infection with the cestode D. caninum has been confirmed, concomitant treatment against intermediate hosts, such as fleas and lice, should be discussed with a veterinarian to prevent re-infection.

Studies with milbemycin oxime indicate that the margin of safety in certain dogs of Collie or related breeds is less than in other breeds. In these dogs, the recommended dose should be strictly observed.

The tolerance of Elanco Milbemycin - Praziquantel 12.5 mg/125 mg tablets for dogs in young puppies from these breeds has not been investigated. Clinical signs in Collies are similar to those seen in the general dog population when overdosed (see section 4.10).
