FULL PRESCRIBING INFORMATION
CLINTABS DESCRIPTION
Clintabs Tablets contain clindamycin hydrochloride which is the hydrated salt of clindamycin. Clindamycin is a semisyntheic antibiotic produced by a 7(S)-chlorosubstitution of the 7(R)-hydroxyl group of a naturally produced antibiotic produced by Streptomyces lincolnensis var. lincolnensis.
Clintabs Tablets (For Use in Dogs Only)
25 mg Tablet, each white bisected tablet is marked "C" above the bisect and "25" below the bisect and contains clindamycin hydrochloride equivalent to 25 mg of clindamycin.
75 mg Tablet, each white bisected tablet is marked "C" above the bisect and "75" below the bisect and contains clindamycin hydrochloride equivalent to 75 mg of clindamycin.
150 mg Tablet, each white tablet is marked "C 150" on one side and contains clindamycin hydrochloride equivalent to 150 mg of clindamycin.
ACTIONS
Site and Mode of Action
Clindamycin is an inhibitor of protein synthesis in the bacterial cell. The site of binding appears to be in the 50S sub-unit of the ribosome. Binding occurs to the soluble RNA fraction of certain ribosomes, thereby inhibiting the binding of amino acids to those ribosomes. Clindamycin differs from cell wall inhibitors in that it causes irreversible modification of the protein-synthesizing subcellular elements at the ribosomal level.
MICROBIOLOGY
Clindamycin is a lincosaminide antimicrobial agent with activity against a wide variety of aerobic and anaerobic bacterial pathogens. Clindamycin is a bacteriostatic compound that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit. The minimum inhibitory concentrations (MICs) of Gram-positive and obligate anaerobic pathogens isolated from dogs in the United States are presented in Table 1. Bacteria were isolated in 1998-1999. All MICs were performed in accordance with the National Committee for Clinical Laboratory Standards (NCCLS).

PHARMACOLOGY
Absorption
Clindamycin hydrochloride is rapidly absorbed from the canine gastrointestinal tract.
Dog Serum Levels
Serum levels at or above 0.5 µg/mL can be maintained by oral dosing at a rate of 2.5 mg/lb of clindamycin hydrochloride every 12 hours. This same study revealed that average peak serum concentrations of clindamycin occur 1 hour and 15 minutes after oral dosing. The elimination half-life for clindamycin in dog serum was approximately 5 hours. There was no bioactivity accumulation after a regimen of multiple oral doses in healthy dogs.
METABOLISM AND EXCRETION
Extensive studies of the metabolism and excretion of clindamycin hydrochloride administered orally in animals and humans have shown that unchanged drug and bioactive and bioinactive metabolites are excreted in urine and feces. Almost all of the bioactivity detected in serum after clindamycin hydrochloride administration is due to the parent molecule (clindamycin). Urine bioactivity, however, reflects a mixture of clindamycin and active metabolites, especially N-dimethyl clindamycin and clindamycin sulfoxide.
ANIMAL SAFETY SUMMARY
Rat and Dog Data
One year oral toxicity studies in rats and dogs at doses of 30, 100 and 300 mg/kg/day (13.6, 45.5 and 136.4 mg/lb/day) have shown clindamycin hydrochloride capsules to be well tolerated. Differences did not occur in the parameters evaluated to assess toxicity when comparing groups of treated animals with contemporary controls. Rats administered clindamycin hydrochloride at 600 mg/kg/day (272.7 mg/lb/day) for six months tolerated the drug well; however, dogs orally dosed at 600 mg/kg/day (272.7 mg/lb/day) vomited, had anorexia, and subsequently lost weight. At necropsy these dogs had erosive gastritis and focal areas of necrosis of the mucosa of the gallbladder.
Safety in gestating bitches or breeding males has not been established.
INDICATIONS
Clintabs (brand of clindamycin hydrochloride) Tablets (for use in dogs only) are indicated for the treatment of infections caused by susceptible strains of the designated microorganisms in the specific conditions listed below:
Dogs
Skin infections (wounds and abscesses) due to: coagulase positive staphylococci (Staphylococcus aureus or Staphylococcus intermedius).
Deep wounds and abscesses due to Bateroides fragilis, Prevotella melaninogenicus, Fusobacterium necrophorum and Clostridium perfringens.
Dental infections due to Staphyloccus aureus, Bacteroides fragilis, Prevotella melaninogenicus, Fusobacterium necrophorum and Clostridium perfringens.
Osteomyelitis due to Staphylococcus aureus, Bacteroides fragilis, Prevotella melaninogenicus, Fusobacterium necrophorum and Clostridium perfringens.
CLINTABS CONTRAINDICATIONS
Clintabs Tablets are contraindicated in animals with a history of hypersensitivity to preparations containing clindamycin or lincomycin.
Because of potential adverse gastrointestinal effects, do not administer to rabbits, hamsters, guinea pigs, horses, chinchillas or ruminating animals.
WARNINGS
Keep out of reach of children. Not for human use.
PRECAUTIONS
During prolonged therapy of one month or greater, periodic liver and kidney function tests and blood counts should be performed.
The use of clindamycin hydrochloride occasionally results in overgrowth of non-susceptible organisms such as clostridia and yeasts. Therefore, the administration of Clintabs Tablets should be avoided in those species sensitive to the gastrointestinal effects of clindamycin (see CONTRAINDICATIONS ).
Should superinfections occur, appropriate measures should be taken as indicated by the clinical situation.
Patients with very severe renal disease and/or very severe hepatic disease accompanied by severe metabolic aberrations should be dosed with caution, and serum clindamycin levels monitored during high-dose therapy.
Clindamycin hydrochloride has been shown to have neuromuscular blocking properties that may enhance the action of other neuromuscular blocking agents. Therefore, Clintabs Tablets should be used with caution in animals receiving such agents.
Safety in gestating bitches or breeding male dogs has not been established.
CLINTABS ADVERSE REACTIONS
