Pergocoat 1mg Film-Coated Tablet for Horses

Pergolide for horses with PPID (Equine Cushing's Disease)

Pergolide is a synthetic ergot derivative that acts as a long-acting dopamine receptor agonist. In horses with Pituitary Pars Intermedia Dysfunction (PPID), pergolide works by stimulating dopamine receptors, and it has been shown to decrease plasma levels of ACTH, MSH and other pro-opiomelanocortin peptides.

PPID is diagnosed by your vet using endocrinologic laboratory tests alongside an evaluation of clinical signs. Lifelong treatment is anticipated, and the dose is adjusted to each horse's response.

About Pergocoat 1mg Film-Coated Tablets for Horses:

• Active ingredient: pergolide 1mg per tablet (equivalent to 1.31mg pergolide mesilate).
• Starting dose for 401-600kg horses: a 1mg daily starting dose is recommended for horses of 401 to 600kg.
• Once daily, by mouth: tablets can be dissolved in a small amount of water and/or mixed with molasses or other sweetener and given by syringe. Tablets should not be crushed.
• For horses aged 2 years and over that are not intended for human consumption.
• Priced per tablet, so your prescription can be dispensed in the quantity your vet prescribes.

Dispensed against your vet's prescription

Pergocoat is a prescription-only veterinary medicine. Your vet will repeat testing every 4 to 6 weeks while the dose is adjusted, then every 6 months once your horse is stable. A 0.5mg strength is also available for smaller horses. Find more for horses in our equine care range, see how we dispense pet prescriptions, or read our pet prescription questions guide.

Always follow the directions and dosage given to you by your prescriber.

Dosage

Oral use, once daily. Do not use in horses less than 2 years of age.

To facilitate administration, the required daily dose should be placed in a small amount of water and/or mixed with molasses or other sweetener and agitated until dissolved. In this case, the dissolved tablets should be administered with a syringe. The whole amount should be administered immediately. Tablets should not be crushed.

Starting dose: the starting dose is about 2 µg pergolide/kg (dose range: 1.3 to 2.5 µg/kg). The maintenance dose should then be titrated according to the individual response as determined by monitoring, resulting in an average maintenance dose of 2 µg pergolide/kg bodyweight with a dose range of 0.6 to 10 µg pergolide/kg bodyweight.

Starting doses are recommended as follows:

• Horses 200-400kg: 0.5mg daily (dosage range 1.3-2.5 µg/kg).
• Horses 401-600kg: 1.0mg daily (dosage range 1.7-2.5 µg/kg).
• Horses 601-850kg: 1.5mg daily (dosage range 1.8-2.5 µg/kg).
• Horses 851-1000kg: 2.0mg daily (dosage range 2.0-2.4 µg/kg).

Your vet will prescribe the combination of tablets that makes up the dose.

Maintenance dose: lifelong treatment is anticipated for this disease. Most horses are stabilised at an average dose of 2 µg pergolide/kg body weight. Clinical improvement with pergolide is expected within 6 to 12 weeks. Horses may respond clinically at lower or varying doses; it is therefore recommended to titrate to the lowest effective dose per individual based on response to therapy, whether it is effectiveness or signs of intolerance. Some horses may require doses as high as 10 µg pergolide/kg body weight per day. In these rare situations, appropriate additional monitoring is advised.

Following initial diagnosis, repeat endocrinologic testing for dose titration and monitoring of treatment at intervals of 4 to 6 weeks until stabilisation or improvement of clinical signs and/or diagnostic testing occurs.

If clinical signs or diagnostic testing have not yet improved at the first 4 to 6 week interval, the total daily dose may be increased by 0.25 - 0.50 mg. In case clinical signs have improved but are not yet normalised, the veterinarian may decide to titrate or not to titrate the dose, considering the individual's response/tolerance to the dose.

In case clinical signs are not adequately controlled, it is recommended to increase the total daily dose by 0.25 - 0.5 mg increments (if the drug is tolerated at that dose) every 4 to 6 weeks until stabilisation occurs. If signs of dose intolerance develop, treatment should be stopped for 2 to 3 days and reinstated at one-half of the previous dose. The total daily dose may then be titrated back up to the desired clinical effect by 0.25 - 0.5 mg increments every 2 to 4 weeks. If a dose is missed, the next scheduled dose should be administered as prescribed.

Following stabilisation, regular clinical assessment and diagnostic testing should be performed every 6 months to monitor treatment and dose. Where there is no apparent response to treatment, the diagnosis should be re-evaluated.

Before use

Do not use:

• in horses with known hypersensitivity to pergolide mesilate or other ergot derivatives or to any of the excipients.
• in horses less than 2 years of age.

Special warnings: appropriate endocrinologic laboratory tests should be conducted as well as evaluation of clinical signs in order to establish a diagnosis of PPID.

Special precautions for use in horses: as the majority of cases of PPID are diagnosed in aged horses, other pathological processes are frequently present.

Precautions for the person giving the product:

• Pergolide, like other ergot derivatives, may cause emesis, dizziness, lethargy or low blood pressure. Severe adverse events such as collapse have been observed. Ingestion may be harmful and associated with severe adverse events, especially in children or people with pre-existing heart conditions. Take utmost care to avoid accidental ingestion.
• Avoid hand-to-mouth contact. Do not eat, drink or smoke when using this product.

• This product may cause eye irritation. Avoid contact with the eyes including hand-to-eye contact when handling the tablets. Minimise exposure risks when dissolving the tablets, e.g. tablets should not be crushed. In case of contact of the dissolved product with skin, wash exposed skin with water. In the event of eye exposure, flush the affected eye immediately with water and seek medical advice.
• Wash hands after use.
• This product may cause hypersensitivity (allergy) reactions. People with known hypersensitivity to pergolide or other ergot derivatives should avoid contact with the product.
• This product may cause adverse effects due to decreased prolactin levels, which poses a particular risk to pregnant and lactating women. Pregnant or lactating women should avoid dermal contact or hand-to-mouth contact and wear gloves when administering the product.

Pregnancy and lactation: the safety has not been established during pregnancy or lactation. Pregnancy: use only according to the benefit/risk assessment by the responsible veterinarian. Lactation: the use is not recommended during lactation.

Interactions:

• Use with caution in case the product is co-administered with other drugs known to affect protein binding.
• Do not administer concurrently with dopamine antagonists, such as neuroleptics (phenothiazines - e.g. acepromazine), domperidone, or metoclopramide, as these agents may reduce the effectiveness of pergolide.

Withdrawal periods: not authorised for use 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. Not authorised for use in animals producing milk for human consumption.
