WE HELP VETS AND PETS!

Compounding allows veterinarians to broaden their prescribing abilities and offer patient-specific dosages.

Pharmacists Helping Vets and Pets

Our specialty service should not be viewed as competition with local veterinarians; rather, compounding allows veterinarians to broaden their prescribing abilities and to offer [dosage] forms that are patient-specific in strength and formulation. Therefore, the goal of compounding for the veterinary patient is to enhance the veterinarian’s ability to treat patients in a more effective and efficient manner…

“Compounding can make medicating animals easier if the pharmacist prepares flavored chews that animals accept readily…. Furthermore, the amount of medication incorporated into the chews, capsules, [topical or transdermal], or liquid preparations can be formulated to the specific request of the veterinarian, thereby eliminating the need to cut-up tablets and divide the contents of commercially prepared capsules… As manufacturers decide that certain products are no longer economically rewarding to market, the list of commercially prepared veterinary medication becomes smaller. At present, the armamentarium of medications available for animals is less than perfect. Cherry-flavored Amoxicillin or orange-flavored Cephalexin may not be [appealing to a cat or monkey]…”

Our compounding pharmacy can prepare for vets and pets:

  • Flavored medications
  • Medicine in ideal size, strength, and dosage form
  • Unavailable medications
  • Combinations to improve compliance

Compounding is actually a means to an end. We work together with veterinarians and their clients and patients to solve medication problems by compounding specialized medications that meet the unique needs of each animal – pets, exotics, horses, or zoo animals. Let us know how we can help you and the animals in your care.

Metronidazole

Metronidazole is effective against a variety of obligate anaerobic bacteria as well as anaerobic protozoa such as Giardia and Trichomonas. “Various salts of metronidazole with improved palatability are now available for veterinary patients… Cats and birds accept the benzoate salt much more willingly than they accept metronidazole HCl and do not seem to be stressed by its administration.”

Metronidazole should be used with caution in patients with hepatic dysfunction. Therapy should be promptly discontinued if abnormal neurological signs appear, including nystagmus, ataxia, seizures, and rigidity. All benzene moieties must be conjugated with glucuronide to facilitate elimination and this pathway is inefficient in cats. Therefore, doses of metronidazole benzoate above 200 mg/kg/day may produce signs of cumulative toxicity in cats within 48 to 72 hours.

Esophageal Strictures Secondary to Administration of Doxycycline Tablets

“The most common causes of esophageal strictures in dogs and cats are gastroesophageal reflux during anesthesia, persistent vomiting, or ingestion of foreign bodies or caustic agents. In humans, esophageal retention of oral medication is a common cause of severe esophagitis. Of the medications proven to lead to esophageal ulceration, doxycycline is most often implicated. It has been suggested that pill-induced esophagitis also could occur in small animals…” Drug-induced esophageal ulceration usually occurs when tablets are taken with little or no water and adhere to the esophageal mucosa. Once this occurs, flushing with large quantities of liquid fails to wash the medication into the stomach. Melendez et al. of Colorado State University College of Veterinary Medicine report on three cases of presumptive doxycycline-induced esophagitis in cats, with resultant stricture formation. All cats had been administered fractions of doxycycline tablets one to three weeks before presenting with a chief complaint of regurgitation. “Two of the cases developed regurgitation within 7 days after initiation of therapy with doxycycline. One cat, which was treated while at an animal shelter, was noted to be regurgitating the day that it was adopted, approximately 2 weeks after being treated with doxycycline. No other cause of esophageal stricture formation could be identified.” If a pet that has received a doxycycline tablet shows sign of esophagitis (dysphagia, excessive salivation, inappetence, and regurgitation), the doxycycline tablets should be discontinued. Suggested therapy for esophagitis includes sucralfate slurries, a prokinetic agent (i.e. cisapride) to increase lower esophageal sphincter tone, and anti-inflammatory doses of glucocorticoids to prevent stricture formation.

Doxycycline can be compounded as a stable flavored liquid preparation or other palatable dosage form to meet the specific needs of each animal and owner.

Oral Itraconazole for Therapy of Dermatophytosis Caused by Microsporum canis

Itraconazole could be an effective alternative to griseofulvin that has toxic effects (particularly in puppies based on this author’s experience) and frequent therapeutic relapses. Itraconazole has also been used to successfully treat M. canis infection of cats and guinea pigs.

Chloramphenicol Suspension for Birds & Small Animals

Since chloramphenicol palmitate is no longer commercially available, we contacted our compounding pharmacist for an alternative for use in our avian and other small patients, such as rabbits and rodents. The pharmacist prepared a cola flavored suspension containing 30 mg/ml of chloramphenicol palmitate, which could be administered using a small oral syringe. However, birds did not like the taste and it was reformulated into a tutti fruitti and pina colada syrup. The “animal appropriate” flavor has really helped with compliance, because now the birds and small animals like to take their medicine!

Note: To avoid potential antagonism, chloramphenicol should not be administered simultaneously with penicillin or streptomycin. Chloramphenicol-containing preparations should not be administered in conjunction with, or two hours prior to, the induction of general anesthesia with pentobarbital.
When administered orally in dogs, chloramphenicol is well-tolerated, has high clinical efficacy, and a low incidence of side effects. The recommended canine dosage is 25 mg/lb of body weight every six hours.

Precautions: Chloramphenicol should be administered cautiously to animals with hematopoietic dysfunction, or impaired kidney or liver function.

Antibiotic Treats for Feline Abscess

Submitted by: Michael Briggs, Pharm.D. Veterinarian: Rich Marchetti, D.V.M.
Patient: One year old non-castrated short-haired male cat with abscess from wound received in fight. The owner reported that the cat, who is usually affectionate and friendly toward the owner and house dog, had been withdrawn, on guard, and growling for approximately three days. A thorn-like projection near the tail was found by the owner, who immediately took the cat to the veterinarian. The cat was anesthetized and the veterinarian cleaned, debrided, and shaved the area of the wound, and prescribed amoxicillin 100 mg daily for ten days. The owner was instructed to keep the cat inside for the duration of therapy, to minimize the risk of superinfection and avoid additional injury.

Medication Problem: The cat refused to take liquids, and was also resistant to taking tablets (“pilling”). The required dose of antibiotic was too high for transdermal treatment (due to the amount of gel that would need to be applied for each dose).
Solution: The veterinarian called our compounding pharmacy and asked if we could come up with a palatable dosage form. We formulated a fish-flavored chewable treat containing amoxicillin 100 mg to be given once daily for ten days. This dosage form offers the advantage of ease of administration, decreases the potential for dosing errors, and greatly increases patient compliance. The cat readily consumed the amoxicillin “treat”. The wound did not heal in a ten day period, so five additional days of therapy were required.

Comment: Our pharmacy has compounded this preparation more than ten times with a 100% success rate.

Intranasal Clotrimazole for Treatment of Nasal Aspergillosis in Dogs

“Treatment of nasal aspergillosis with systemic antifungal medications, such as thiabendazole, ketoconazole, and fluconazole, has been disappointing because the response rate is only 43 to 60%. Response to oral administration of itraconazole has been approximately 60 to 70%… Topical administration of the imidazoles, enilconazole, and clotrimazole is more effective than orally administered antifungal medications.”

Topical administration of clotrimazole resulted in resolution of clinical disease in 65% of dogs after 1 treatment and 87% of dogs after one or more treatments. Topical administration of clotrimazole, using either technique, was an effective treatment for nasal aspergillosis in dogs. Use of non-invasive intranasal infusion of clotrimazole eliminated the need for surgical trephination of frontal sinuses in many dogs and was associated with fewer complications. Nasal discharge ceased in most dogs 2 weeks after topical treatment, and the authors now recommend re-treatment with clotrimazole if nasal discharge has not improved 2 weeks after treatment.
“[Damage] of the cribriform plate may contraindicate use of topical treatment; complications arising from leakage of antifungal medications into the CNS in dogs with fungal rhinitis have not been evaluated.”
