4.3 Contraindications

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

Do not administer to rabbits, hamsters, guinea pigs, chinchillas, horses or ruminants because ingestionof clindamycin by these species may result in severe gastro-intestinal disturbance.

4.4 Special warnings for each target species

None.

4.5 Special precautions for use

Special precautions for use in animals

The chewable tablets are flavoured. In order to avoid any accidental ingestion, store tablets out of reach of the animals.

Use of the product should be based on susceptibility testing of the bacteria isolated from the animal.

Official and local antimicrobial policies should be taken into account when the product is used.

Use of the product deviating from the instructions given in the SPC may increase the prevalence of bacteria resistant to clindamycin and may decrease the effectiveness of treatment with lincomycin or macrolide antimicrobials due to the potential for cross‑resistance

Clindamycin and erythromycin show parallel resistance. Partial cross-resistance has been demonstrated between clindamycin, erythromycin and other macrolides antibiotics.

During prolonged therapy of one month or greater, periodic liver and kidney function tests and blood counts should be performed.

Animals with severe renal and/or very severe hepatic disturbances accompanied by severe metabolic aberrations should be dosed with caution and should be monitored by serum examination during high-dose clindamycin therapy.

The use of the product is not recommended in suckling puppies.

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

People with known hypersensitivity to lincosamides (lincomycin and clindamycin)should avoid contact with the veterinary medicinal product.

Wash hands after handling tablets.

Accidental ingestion may result in gastro-intestinal effects such as abdominal pain and diarrhoea. Care should be taken to avoid accidental ingestion.

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

4.6 Adverse reactions (frequency and seriousness)

Vomiting and diarrhoea have occasionally been observed.

Clindamycin sometimes causes the overgrowth of non-sensitive organisms such as clostridia and yeasts. In cases of superinfection, appropriate measures must be taken according to the clinical situation.

4.7 Use during pregnancy, lactation or lay

While high dose studies in rats suggest that clindamycin is not a teratogen and does not significantly affect the breeding performance of males and females, safety in gestating bitches or breeding male dogs has not been established.

Clindamycin crosses the placental and the blood-milk barrier.

Treatment of lactating females can cause diarrhoea in puppies.

Use the product only according to the benefit/risk assessment by the responsible veterinarian.

4.8 Interaction with other medicinal products and other forms of interaction

Clindamycin hydrochloride has been shown to have neuromuscular blocking properties that may enhance the action of other neuromuscular blocking agents. The product should be used with caution in animals receiving such agents.

Clindamycin should not be combined with erythromycin or other macrolides to prevent macrolide-induced resistance to clindamycin.

Clindamycin may reduce plasma levels of cyclosporin with a risk of lack of activity.

During the simultaneous use of clindamycin and aminoglycosides (eg gentamicin), the risk of adverse interactions (acute renal failure) cannot be excluded.

4.9 Amounts to be administered and administration route

For oral administration

• 5.5 mg/kg of bodyweight every 12 hours for 7-10 days, or

• 11 mg/kg of bodyweight every 24 hours for 7-10 days

If no clinical response is seen within 4 days, redetermine the diagnosis.

• 5.5 mg/kg of bodyweight every 12 hours, or

• 11 mg/kg of bodyweight every 24 hours

Therapy of superficial pyoderma is usually recommended for 21 days, with extension of therapy based on clinical judgement.

If no clinical response is seen within 14 days, the treatment should be stopped and the diagnosis redetermined.

For example:

Weight (kg)	Number of tablets per administration
2.5 – 3.4	¼ tab
3.4- 4.4	Use Zodon 88 mg
4.5 – 6.5	½ tab
6.6– 10.0	¾ tab
10.1 – 13.5	1 tab
13.6 – 17.0	1 + ¼ tab
17.1 – 20.5	1+ ½ tab
20.6 – 23.9	1 + ¾ tab
24.0 – 27.0	tabs

Weight (kg)	Number of tablets per administration
2.5- 4.4	Use Zodon 88 mg
4.5 – 6.5	¼ tab
6.6– 13.5	½ tab
13.6 – 20.5	¾ tab
20.6 – 27.0	1 tab

To ensure a correct dosage, body weight should be determined as accurately as possible to avoid under-dosing.

The tablets are flavoured. They can be administered directly into the mouth of the animals or with a small quantity of food.

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

In dogs, oral doses of clindamycinup to 300 mg/kg/day did not result in toxicity. Dogs receiving 600 mg/kg/day of clindamycindeveloped anorexia, vomiting and weight loss. In cases of overdose, discontinue treatment immediately and establish symptomatic treatment

4.11 Withdrawal period(s)

Not applicable.

5. PHARMACOLOGICAL PROPERTIES

Pharmacotherapeutic group: Anti-infectives for systemic use, lincosamides

ATC Vet Code: QJ01FF01

5.1 Pharmacodynamic properties

Mode of action

Clindamycin is a semi-synthetic antibiotic produced by 7(S)-chloro substitution of the 7(R)-hydroxy group of the natural antibiotic produced by Streptomyces lincolnensis var. lincolnensis.

Clindamycin acts by a bacteriostatic mechanism where the drug interferes with protein synthesis within the bacterial cell, thus inhibiting the growth and multiplication of the bacteria. Clindamycin binds to the 23S ribosomal RNA component of the 50S subunit. This prevents amino acids binding on these ribosomes, and therefore inhibits peptide bond formation.The ribosomal sites are close to those bound by macrolides, streptogramins or chloramphenicol.

Antibacterial spectrum

Clindamycin is a moderate spectrum antimicrobial drug.

Susceptible microorganisms (S):

Clindamycin has in vitro activity against the following micro-organisms (see the following MICs):

• Aerobic Gram-positive cocci, including: Staphylococcus aureus and Staphylococcus pseudintermedius (penicillinase and non-penicillinase producing strains), Streptococcus spp. (except Streptococcus faecalis).

• Anaerobic Gram-negative bacilli, including: Bacteroides spp., Fusobacterium necrophorum.

• Clostridia: Most Clostridium perfringens are susceptible.

MIC data

CLSI clindamycin veterinary breakpoints are available for dogs in Staphylococcusspp. and Streptococci-ß-haemolytic group in skin and soft tissue infections: S ≤0.5μg/ml; I=1-2μg/ml; R ≥4μg/ml.(CLSI July 2013).

Type and mechanism of resistance

Clindamycin belongs to the lincosamide group of antibiotics. Resistance can develop to the lincosamides alone, but more commonly cross-resistance occurs among macrolides, lincosamides and streptogramin B antibiotics (MLS_Bgroup). Resistance is the result of methylation of adenine residues in the 23S RNA of the 50S ribosomal subunit, which prevents drug binding to the target site. Different bacterial species are able to synthesize an enzyme, encoded by a series of structurally related erythromycin ribosomal methylase (erm) genes. In pathogenic bacteria, these determinants are mostly borne by plasmids and transposons that are self-transferable. The erm genes occur predominantly as variants erm(A) and erm(C) in Staphylococcus aureusand as variant erm(B) in Staphylococcus pseudintermedius, streptococci and enterococci . Bacteria resistant to macrolides but initially susceptible to clindamycin, rapidly develop resistance to clindamycin when exposed to macrolides. These bacteria present a risk ofin vivoselection of constitutive mutants.

MLS_Binducible resistance is not detected by standard in vitro susceptibility testing methods. The CLSI recommends the D-zone test to be routinely performed in veterinary diagnostic laboratories in order to detect clinical isolates with inducible resistance phenotype. Clindamycin use should be discouraged in these patients.

The incidence of resistance to lincosamides in Staphylococcus spp. appears to be wide-ranging in Europe. Recent studies (2010) report an incidence between 25 to 40%.

5.2 Pharmacokinetic particulars

Absorption:

Clindamycin hydrochloride is rapidly absorbed from the canine gastrointestinal tract following oral administration.

Serum values:

After oral administration of 13.1 mg/kg bodyweight, the maximal plasma concentration of

6.4 µg/ml (Mean C_max) is reached within 50 minutes (Mean T_max). The biological plasma half-life of clindamycin in the dog is approximately 5 hours. No accumulation of bioactivity has been observed in dogs after several oral administrations.

Metabolism and Excretion:

Extensive research of the metabolism and excretion pattern of clindamycin shows that the parent molecule as well as bioactive and bio-inactive metabolites are excreted via the urine and faeces.

Nearly all bioactivity in the serum following oral administration is due to the parent molecule (clindamycin)
