4. Clinical particulars
4.1 Target species
Cattle and horses.
4.2 Indications for use, specifying the target species
The in vitroactivity covers most common Gram-positive and Gram-negative bacteria including Actinobacillusspp., Actinomycesbovis, Bordetella spp., Corynebacteriumspp., Klebsiellaspp., Listeriamonocytogenes, Nocardia spp., Pasteurellaspp., Proteusspp., Salmonellaspp., Staphylococcusspp., and Streptococcusspp.
Indications: The injection may be used in the treatment of a wide range of diseases and conditions of bacterial origin in cattle and horses.
Respiratory infections of bacterial origin including pneumonia, rhinitis, bronchitis and secondary bacterial infections following virus pneumonia mycoplasmal infections.
Urogenital tract infections including cystitis, vaginitis, urethritis, nephritis and metritis.
Alimentary tract infections, neonatal diarrhoea, salmonellosis and post- weaning enteritis.
4.3 Contraindications
Do not administer by the intraperitoneal or subcutaneous route.
Do not administer to horses exhibiting cardiac arrhythmias. Such arrhythmias may be associated with the administration of certain anaesthetic and sedative agents.
4.4 Special warnings for each target species
Very occasionally, temporary irritating swellings may appear at the site of injection.
4.5 Special precautions for use
i. Special precautions for use in animals
The following warnings are applicable to all Trimethoprim Sulfonamide combinations for use in the horse.
Cardiac and respiratory shocks in horses have been observed, mostly after intravenous injection.
The injection solution should be approximately at body temperature. At the first signs of intolerance, the injection should be interrupted and shock treatment initiated. The product should be injected slowly over as long a period as is reasonably practical.
The intravenous route of administration is contra-indicated in the case of previous or concurrent administration of central nervous system depressants (e.g. anaesthetics, neuroleptics).
The possibility of an anaphylactic or hypersensitivity reaction occurring following administration on rare occasions must be borne in mind.
As with all trimethoprim sulphonamide formulations the possibility of potential damage to the kidney or liver or haematopoetic system should be considered.
ii. Special precautions to be taken by the person administering the veterinary medicinal product to animals
Care should be taken to avoid accidental injection and contact with the skin.
Wash hands after use.
Sulphonamides may cause hypersensitivity (allergy) following, injection, inhalation, ingestion or skin contact. Hypersensitivity to sulphonamides may lead to cross reactions with other antibiotics. Allergic reactions to these substances may occasionally be serious.
Do not handle this product if you know you are sensitive to sulphonamides.
If you develop symptoms following exposure such as skin rash, you should seek medical advice and show the doctor this warning.
4.6 Adverse reactions (frequency and seriousness)
Very occasionally, temporary irritating swellings may appear at the site of injection.
4.7 Use during pregnancy, lactation or lay
Studies during pregnancy have not been conducted. Use with care in pregnant animals.
4.8 Interaction with other medicinal products and other forms of interactions
Because of the competitive action of the sulphonamides, their activity may be antagonised by the presence of any of the following:
Para-Aminobenzoic acid (PABA) and related compounds, particularly local anaesthetics with a PABA nucleus such as procaine, butacaine and benzocaine, but also compounds associated with those such as procaine penicillin. It is recommended that local anaesthetics of the procaine group should not be used during treatment with Bimotrim Co Injection.
Some members of the Vitamin B complex, such as nicotinamide, folic acid, choline and precursors of these.
Proteins which combine loosely with the sulphonamides and at least temporarily reduce their antibacterial activity. Gelatin, albumin, peptone and serum protein all antagonise the sulphonamides. Associated with this group are products of cell and tissue death, especially pus, which also acts as a non-vascular, mechanical barrier.
A number of other compounds, including enzymes, glucose and mercuric chloride, are all reported to have antagonistic effects against sulphonamides.
4.9 Amounts to be administered and administration route
Dose: 15mg/kg (equivalent to 1 ml per 16 kg bodyweight) daily. Daily dosing should be repeated for two days after symptoms have resolved up to a maximum of 5 days.
Route of administration:
Cattle: By slow intravenous or intramuscular injection. Intramuscular injection is the preferred route and should be given into the neck.
Horses: By slow intravenous injection.
4.10 Overdose (symptoms, emergency procedure. antidotes), if necessary
Do not exceed the recommended dose or treat animals for more than 5 consecutive days.
4.11 Withdrawal periods
Cattle: Meat & offal: 10 days. Milk: 60 hours
Horses: Not to be used in horses intended for human consumption.
Treated horses may never be slaughtered for human consumption.
The horse must have been declared as not intended for human consumption under national horse passport legislation.
5. Pharmacological properties
The two active ingredients (Sulfadoxine and Trimethoprim) produce a sequential double blockade of bacterial synthesis of folic acid, giving a level of activity many times greater than that obtained from either drug alone. Both are eliminated from plasma partly by metabolism and partly by excretion of the unchanged compounds in urine or faeces.
50% of total Trimethoprim (TMP) is bound to plasma protein whereas the binding of Sulfadoxine depends on total plasma concentration and varies between 14 and 72%. Trimethoprim has a high therapeutic index and a wide antibacterial activity in vitro.Trimethoprim is more lipophilic and penetrates tissues better than sulphadoxine, which is reflected by its consistently higher distribution volume. Highest concentrations of Trimethoprim are found in liver and kidney while sulphadoxine is detected in high concentrations in liver, kidney, duodenum and lung.
