Cardiac emergencies ■■ Asystole or pulseless electrical activity Adrenaline: 20 μg (micrograms)/kg i.v. – this is equivalent to 1 ml/5 kg using 1:10,000 concentration (100 μg/ml). Double dose if used intratracheally. ■■ Hyperkalaemic myocardial toxicity Calcium: 50–150 mg/kg calcium (boro)gluconate = 0.5–1.5 ml/kg of a 10% solution i.v. over 20–30 min or Soluble insulin: 0.5 IU/kg i.v. followed by 2–3 g of dextrose/unit of insulin (for urinary tract obstruction but not hypoadrenocorticism). Half the dextrose should be given as a bolus and the remainder administered i.v. over 4–6h. ■■ Other bradyarrhythmias Atropine: 0.01–0.03 mg/kg i.v. – this is equivalent to 0.3–1 ml/20 kg using 0.6 mg/ml solution. ■■ Ventricular tachycardia Lidocaine: Dogs: 2–8 mg/kg i.v. in 2 mg/kg boluses, followed by a constant rate i.v. infusion of 0.025–0.1 mg/kg/min. Cats: 0.25–2.0 mg/kg i.v. slowly in 0.25–0.5 mg/kg boluses followed by a constant rate i.v. infusion of 0.01–0.04 mg/kg/min. Pulmonary emergencies ■■ Respiratory arrest Doxapram: 5–10 mg/kg i.v., repeat according to need; duration of effect is approximately 15–20 min.

Everyone involved in its production hopes you find it a useful C resource. There are 12 new drug monographs and there have been many deletions since the last edition as older drugs become D unavailable or newer drugs make them obsolete. Most of the remaining monographs have had minor revisions and some have had E major changes. The Appendix has been thoroughly revised and some of the information has been moved to the BSAVA website, where it is F accessible to BSAVA members. G The labelling of veterinary medicines has also been examined in greater depth than ever before. The law is clear, but not practical, and H veterinary surgeons must tread a fine line between compliance and practical solutions. Client Information Leaflets (CILs) are available I from the BSAVA for a number of the drugs listed in the Formulary which do not have a marketing authorization for veterinary use in the J UK. These leaflets go a long way towards providing practical information in a client-friendly format. However, they are not a K substitute for explaining the ‘Cascade’ system to owners and the details of the particular drugs that have been prescribed. L Drug formularies are progressively evolving works and the latest M updates are available on the BSAVA website. The doses provided should always be read in conjunction with the rest of the monograph, N which contains important information on the use of the drug. In an ideal world, all the information in this book would be based on O peer-reviewed literature. In reality, we rely on the experience of our Editorial Panel to integrate, and often extrapolate from, the variable P sources of information. Q I would, once again, like to thank the dedication of my colleagues on the Editorial Panel who have examined each monograph for scientific R accuracy, relevance and practical application. I am also grateful to the publishing team at Woodrow House for their assistance and S patience. I am indebted to the many readers and BSAVA members who have taken time to discuss with me and comment on entries in T the Formulary. U Ian Ramsey January 2014 V W X Y Z 1 Prelims.indd 6 11/02/2014 14:54 BSAVA Small Animal Formulary 8th edition vii Foreword A B The BSAVA Small Animal Formulary continues to be one of the Association’s most valued practical resources for veterinary surgeons C and is one of our key membership benefits. The availability of the Formulary as an app version for mobile devices has enhanced D enormously the rapid accessibility of this fundamental information in a practice setting. E Professor Ian Ramsey and his team are to be congratulated on bringing out this new and updated 8th edition of the Formulary. As F with previous editions of the Formulary, a number of new drug monographs have been added, whilst those drugs that are no longer G available to the veterinary profession have been removed. The major new addition to this 8th edition of the Formulary is the introduction of H examples of immunosuppressive protocols to the Appendix. I In recent years the prescribing of veterinary medicines has continued to have political prominence. In particular, concerns over J antimicrobial resistance in human and veterinary medicine have captured attention on a global scale. BSAVA, in collaboration with the K Small Animal Medicine Society (SAMSoc), has led the response of small animal practitioners to this debate. The PROTECT poster and L accompanying literature (freely available on the BSAVA website) provides practitioners with key facts and strategies to minimize M antimicrobial resistance in small animal practice. It is pleasing that the PROTECT concept has been adopted by other UK and N international associations in promoting this important message. O Professor Michael J.

The rINN generic name is used where this has been O R agreed. When a choice of names is available the more commonly T N used in the UK has been provided. The list of trade names is not I necessarily comprehensive, and the mention or exclusion of any particular commercial product is not a recommendation or otherwise as to its value. Any omission of a product that is authorized for a particular small animal indication is purely accidental. All monographs were updated in the period July–December 2013. Products that are not authorized for veterinary use by the Veterinary Medicines Directorate are marked with an asterisk. Note that an indication that a product is authorized does not necessarily mean that it is authorized for all species and indications listed in the monograph; users should check individual data sheets. You may also wish to refer to the VMD’s Product Information Database (www.vmd.defra.gov.uk/ ProductInformationDatabase/). • Formulations. Only medicines and formulations that are available in the UK have been included – many others are available outside the UK and some medicines in different formulations. Common trade names of human medicines are provided. In many cases they are available as generic formulations and may be cheaper. However, be careful of assuming that the bioavailability of one brand is the same as that of another. Avoid switching between brands unnecessarily. • Action and Use. Veterinary surgeons using this publication are warned that many of the drugs and doses listed are not currently authorized by the Veterinary Medicines Directorate (VMD) or the European Agency for the Evaluation of Medicinal Products (EMEA) (either at all or for a particular species), or manufacturers’ recommendations may be limited to particular indications. The decision, and therefore the responsibility, for prescribing any drug for an animal lies solely with the veterinary surgeon. Expert assistance should be obtained when necessary. The ‘cascade’ and its implications are discussed below. • Safety and handling. This section only outlines specific risks and precautions for a particular drug that are in addition to the general advice given below in the ‘Health and safety in dispensing’ section. A separate Appendix deals with chemotherapeutic drugs. • Contraindications and Adverse reactions: The list of adverse reactions is not intended to be comprehensive and is limited to those effects that may be of clinical significance. The information for both of these sections is taken from published veterinary and human references and not just from product literature. • Drug interactions. A listing of those interactions which may be of clinical significance. • Doses. These are based on those recommended by the manufacturers in their data sheets and package inserts, or are 2 Intro.indd 8 11/02/2014 14:58
