Study Notes
Pharmacology in Veterinary Medicine
- Opioid agonists include naturally occurring narcotics such as opium and paregoric, as well as synthetic narcotics like meperidine, butorphanol tartrate, and fentanyl
- Opioid antagonists, like naloxone and diprenorphine, are used to block the effects of opioid agonists by binding with opiate receptors
- Neuroleptanalgesics, a combination of an opioid and tranquilizer, are used for sedation, restraint, and anesthesia, with agents including fentanyl & droperidol, acepromazine & morphine, and xylazine & butorphanol
- Drugs to prevent or control seizures include diazepam, phenobarbital, primidone, phenytoin sodium, potassium bromide, and clorazepate, but may have adverse side effects such as drowsiness and CNS depression
- Inhalants, like isoflurane, are converted from liquid to gas by an anesthetic vaporizer and delivered to the lungs to produce unconsciousness, analgesia, and muscle relaxation
- CNS stimulants, such as doxapram, are used to treat respiratory depression or arrest and may have adverse side effects like hypertension, seizures, and hyperventilation
- Neuromuscular blocking drugs, including succinylcholine chloride and nondepolarizing agents like tubocurarine and pancuronium, are muscle relaxants used as an adjunct to general anesthesia and to facilitate intubation
- Behavioral pharmacotherapy addresses separation anxiety, fears, phobias, unruliness, hyperactivity, compulsive disorders, cognitive dysfunction, and inappropriate elimination in animals
- Antianxiety medications like benzodiazepines (diazepam, alprazolam, lorazepam) and azapirones (buspirone) are used to control fears and phobias, separation anxiety, aggression, and anxiety-induced stereotypes
- Antidepressants, including tricyclics like amitriptyline and serotonin reuptake inhibitors like fluoxetine, are used to treat separation anxiety, obsessive disorders, fearful aggression, and hyperactivity, but may have adverse effects such as sedation and anorexia
- Miscellaneous behavior modifiers, like synthetic progestins megestrol acetate and medroxyprogesterone, are used for urine spraying/marking, intermale aggression, and dominance aggression, but may cause adverse side effects such as transient diabetes mellitus
- Euthanasia agents like pentobarbital sodium and T-61 are used for humane euthanasia, but may lead to adverse side effects like muscle twitching and agonal breathing
