Pharmacological properties

4.1 ATCvet code: QJ01DB01.

4.2 Pharmacodynamics

Cefalexin is a semi-synthetic bactericidal antibiotic belonging to the cephalosporin group.

This bactericidal activity is mediated by drug binding to bacterial enzymes known as penicillin binding proteins (PBPs). Such enzymes are located on the inner membrane of the cell wall and their transpeptidase activity is required for the terminal stages of assembling this essential structure of the bacterial cell. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. The bactericidal effect of cefalexin is mainly time dependent.

Cefalexin is active against a wide range of Gram-positive and Gram-negative bacteria. The following micro-organisms have been shown to be sensitive to cefalexin in vitro: Staphylococcus spp (including penicillin-resistant strains), Streptococcus spp, Corynebacterium spp, Pasteurella multocida, Escherichia coli, Micrococcus spp, Moraxella spp.

Cefalexin is resistant to the action of staphylococcal penicillinase and is therefore active against the strains of Staphylococcus aureus that are insensitive to penicillin (or related antibiotics such as ampicillin or amoxycillin) because of production of penicillinase.

Cefalexin is also active against the majority of ampicillin-resistant E.coli.

Resistance to cefalexin can be due to one of the following mechanisms of resistance. Firstly, the production of cephalosporinases, that inactivate the antibiotic by hydrolysis of the β-lactam ring, is the most prevalent mechanism among Gram-negative bacteria. This resistance is transmitted by plasmid or chromosomally. Secondly, a decreased affinity of the PBPs (penicillin-binding proteins) for beta-lactam drugs is frequently involved for beta-lactam resistant Gram-positive bacteria. Lastly, efflux pumps, extruding the antibiotic from the bacterial cell, and structural changes in porins, reducing passive diffusion of the drug through the cell wall, may contribute to improve the resistant phenotype of a bacterium.

Well-known cross-resistance (involving the same resistance mechanism) exists between antibiotics belonging to the beta-lactam group due to structural similarities. It occurs with beta-lactamases enzymes, structural changes in porins or variations in efflux pumps. Co-resistance (different resistance mechanisms involved) has been described in E. coli due to a plasmid harbouring various resistance genes. Pseudomonas aeruginosa is known for resistance to cefalexin.

4.3 Pharmacokinetics

Following oral administration, cefalexin is rapidly and almost completely absorbed. Peak plasma concentrations in the dog (Cmax= 17.49 μg/ml) are achieved within approximately 1.5 hours (Tmax= 1.55). Cefalexin is excreted in the urine in high concentrations and has an elimination half life (T1/2) of approximately 2.5–3 hours.

Target species

Dogs.

3

Indications

Treatment of infections of the respiratory tract, gastrointestinal tract, urogenital tract, the skin and localised infections in soft tissue.

3

Dosage

Oral use.

A dose of 15 mg/kg twice daily is recommended, to be doubled where appropriate.

The veterinary medicinal product has a break mark on both sides. To enable more accurate dosing, half tablets may be used as necessary.

Treatment for five days is recommended. Any increase in dose or duration of use should be according to the benefit-risk assessment by the responsible veterinarian (e.g. in cases of chronic pyoderma).

Tablets may be added to food if necessary.

To ensure a correct dosage, body weight should be determined as accurately as possible.

The use of cefalexin tablets of lower strengths is advised for dogs with lower bodyweights.

3

Contraindications

Do not use in cases of hypersensitivity to the active substance, to other cephalosporins, to other substances of the β-lactam group or to any of the excipients.

Do not use in known cases of resistance to cephalosporins or penicillins.

Do not use in rabbits, gerbils, guinea pigs and hamsters.

3

Adverse reactions

Dogs:

*When observed, the treatment should be discontinued and occurring symptoms should be treated symptomatically.

**When observed, treatment should be stopped and the advice of the attending veterinarian should be sought.

Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system. See the package leaflet for respective contact details.

Warnings

Special precautions for safe use in target species:

Use of the veterinary medicinal product should be based on identification and susceptibility testing of the target pathogen(s) isolated from the animal. If this is not possible, therapy should be based on epidemiological information and knowledge of susceptibility of the target pathogens at local/regional level.

Use of the veterinary medicinal product should be in accordance with official, national and regional antimicrobial policies.

An antibiotic with a lower risk of antimicrobial resistance selection (lower AMEG category) should be used for first line treatment where susceptibility testing suggests the likely efficacy of this approach.

Use of the veterinary medicinal product deviating from the instructions given in the SPC may increase the prevalence of bacteria resistant to cefalexin and may decrease the effectiveness of treatment with other beta-lactam antibiotics, due to the potential for cross-resistance.

As with other antibiotics which are excreted mainly by the kidneys, unnecessary accumulation may occur in the body when renal function is impaired. In cases of known renal insufficiency, the dose should be reduced, antimicrobials known to be nephrotoxic should not be administered concurrently and the veterinary medicinal product should be used only according to the benefit-risk assessment by the responsible veterinarian.

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

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

Penicillins and cephalosporins may cause hypersensitivity (allergy) following injection, inhalation, ingestion or skin contact. Hypersensitivity to penicillin may lead to cross-reactions to cephalosporin and vice versa. Allergic reactions to these substances may occasionally be serious. People with known hypersensitivity to cefalexin should avoid contact with the veterinary medicinal product.

Handle this veterinary medicinal product with great care to avoid exposure, taking all recommended precautions. If you develop symptoms following exposure such as skin rash, you should seek medical advice immediately and show the package leaflet or the label to the physician. Swelling of the face, lips or eyes or difficulty breathing are more serious symptoms and require urgent medical attention.

To avoid accidental ingestion, particularly by a child, unused part-tablets should be returned to the open blister space and inserted back into the outer packaging. In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the label to the physician.

Wash hands after use.

Special precautions for the protection of the environment:

Not applicable.

3.11 Special restrictions for use and special conditions for use, including restrictions on the use of antimicrobial and antiparasitic veterinary medicinal products in order to limit the risk of development of resistance

To be completed in accordance with national requirements.

3

Use during pregnancy, lactation or lay

The safety of the veterinary medicinal product has not been established during pregnancy or lactation. Use only according to the benefit-risk assessment by the responsible veterinarian.

3

Interactions

The bactericidal activity of cephalosporins is reduced by concomitant administration of bacteriostatic acting compounds (macrolides, sulphonamides and tetracyclines). Nephrotoxicity can be increased when 1st generation cephalosporins are combined with polypeptide antibiotics, aminoglycosides and some diuretics (furosemide). Concomitant use with such active substances should be avoided.

3

Overdose

The administration of cefalexin has been shown to produce no serious side effects when administered at overdose.

3

Special warnings

Cross-resistance has been shown between cephalosporins and penicillins. Use of cefalexin should be carefully considered when susceptibility testing has shown resistance to penicillins because its effectiveness may be reduced.
