WARNINGS:
Human Safety Warnings:
Not for use in humans. Keep out of reach of children.
Wear gloves and protective eye wear when handling or administering this product to prevent accidental exposure. In case of accidental eye, oral or skin exposure, flush with water. If wearing contact lenses, eyes should be rinsed first, then remove contact lenses and continue rinsing. Remove contaminated clothing. Ropinirole is a dopamine agonist. Seek medical attention if accidental exposure occurs and show the package insert or label to the physician. Exposure to this drug may cause adverse reactions such as headache, nausea, vomiting, dizziness, orthostatic hypotension, and sleepiness. Avoid contact with the product if pregnant, planning to become pregnant, or breast-feeding, as exposure has been shown to have adverse effects on embryo-fetal development based on rodent studies.
Animal Safety Warnings:
This product should be administered by veterinary personnel.
Dogs should be monitored for CLEVOR-associated clinical signs, including protracted vomiting, salivation, muscle tremors, evidence of abdominal discomfort, lethargy, transient tachycardia, transient decrease in blood pressure and signs of ocular irritation, including conjunctival hyperemia, mild blepharospasm, and protrusion of the third eyelid. These clinical signs are related to the pharmacological action of ropinirole.
To stop protracted vomiting, administer metoclopramide (dopamine D2 antagonist) at a dose of 0.5 mg/kg intravenously (IV) or subcutaneously (SQ). Metoclopramide also decreases the prevalence of most CLEVOR-associated clinical signs.
-
PRECAUTIONS:
The safe use of CLEVOR has not been evaluated in dogs with cardiac disease or cardiovascular compromise. CLEVOR can cause transient tachycardia and transient decreased systolic blood pressure.
The safe use of CLEVOR has not been evaluated in dogs with hepatic impairment. CLEVOR is metabolized by the liver.
The safe use of CLEVOR has not been evaluated in dogs younger than 4.5 months of age and weight less than 4 pounds.
The safe use of CLEVOR has not been evaluated in dogs that are pregnant, lactating, or intended for breeding.
-
ADVERSE REACTIONS:
Safety was evaluated during a field study that enrolled 132 dogs (100 in the CLEVOR group and 32 in the vehicle control group). CLEVOR was administered as drops into the eyes at the dose as directed by the dosing table (see DOSAGE AND ADMINISTRATION). The following table shows the number of dogs exhibiting ocular, systemic, and clinical pathology adverse reactions.

CLINICAL PHARMACOLOGY:
Ropinirole is a full dopamine agonist with selectivity for the dopamine D2-like receptor family. Ropinirole induces vomiting by activating the D2-like receptors in the chemoreceptor trigger zone, located in the area postrema, which transmits the information to the vomiting center to trigger vomiting.
Absorption: Ropinirole solution is rapidly absorbed after ocular administration in dogs. The systemic bioavailability of the drug by this route of administration is 18 to 28%. The maximum concentration (Cmax) after ocular administration at the target dose level of 3.75 mg/m2 was 25.6 ± 7.75 ng/mL at 10 to 20 minutes (Tmax). Cmax in dogs that had to be re-dosed 20 minutes after the first administration was 34.2 ± 11.0 ng/mL at a Tmax of 10 to 60 minutes. Vomiting generally starts before the Cmax in plasma is reached. No direct correlation between the drug concentration in plasma and the duration of vomiting was observed after ocular administration.
Distribution: Ropinirole has a relatively large apparent volume of distribution. In dogs the volume of distribution (Vd) was 5.63 ± 1.40 L/kg after intravenous administration. The fraction bound to plasma proteins in dogs has been reported as 37%.1
Metabolism and Elimination: Ropinirole is mainly eliminated by hepatic metabolism.1,2
The half-life of elimination (t½) is approximately 4 hours after intravenous administration to dogs. Biotransformation occurs by dealkylation, hydroxylation and subsequent conjugation with glucuronic acid or oxidation to carboxylic acid.3,4 Excretion occurs mainly as metabolites in the urine.

EFFECTIVENESS:
Effectiveness was demonstrated in a multi-center, vehicle-controlled, randomized and masked field study in client-owned dogs of various breeds. Dogs enrolled in the study were 7 months to 15 years of age and weighed 1.9 to 66.3 kg. In this study, 132 dogs were enrolled and randomized to treatment with CLEVOR (n=100) or vehicle control (n=32). The effectiveness evaluation population included 99 CLEVOR treated dogs and 29 vehicle control dogs.
Dogs received a dose administered as drops into the eye(s) approximately 1 hour after a meal. The dose was administered according to weight (see Dosage and Administration). If the dog did not vomit within 20 minutes of the first dose, a second dose was administered.
Treatment success was defined for each dog as vomiting within 30 minutes of treatment. The percent of treatment success for CLEVOR was greater than vehicle control. The confidence interval around the estimated success rate 0.969 was (0.831, 0.995).
Table 3. Number and % Effectiveness for CLEVOR and Vehicle Control Time to Vomit CLEVOR ®
(n=99)Vehicle Control
(n=29)0-30 minutes 94 (95%) 0 (0%) The time to first vomition, the number of times the dog vomited, and the description of vomit were evaluated as secondary variables and support the effectiveness of CLEVOR for induction of vomiting in dogs. Eighty-five dogs (86%) in the CLEVOR group vomited within 20 minutes and therefore did not require a second dose. The time to first vomition ranged from 3 minutes to 37 minutes with a mean of 12 minutes. The duration between first and last vomiting episodes ranged from 0 to 108 minutes with a mean duration of 23 minutes. Eight dogs had vomiting episodes over a duration longer than an hour. Five of these eight dogs were administered an antiemetic (metoclopramide). The number of vomits ranged from 0 to 13 vomits with a mean of 4.8 vomits per dog. Of the dogs that vomited, 96% of the dogs produced a vomit containing the meal that had been fed approximately one hour prior to CLEVOR administration.

ANIMAL SAFETY:
In a laboratory study, 32 healthy Beagle dogs aged 4.5 - 5.5 months were administered CLEVOR at 1X, 3X, and 5X the proposed labeled dose of 2.7-5.4 mg/m2 (0.23-0.31 mg/kg), repeated once after 20 minutes [total dose of 8.5-10.6 mg/m2 (0.45-0.62 mg/kg)] (dose divided between both eyes), for 3 days.
Dogs in the CLEVOR groups generally vomited within 5 - 10 minutes of dose administration and none of the dogs in the saline group vomited. Vomiting occurred as often as every 1 - 2 minutes and lasted 1 - 2 hours. Additional systemic effects of CLEVOR included retching, salivation, hunched posture, tremors, labored breathing, lethargy, ventral and lateral recumbency, transient tachycardia, transient decrease in indirect systolic blood pressure (but not less than 125 mmHg), and a dose dependent decrease in body temperature (although all temperatures remained within normal limits). Local ocular effects of CLEVOR included ocular discharge, hyperemia, conjunctival erythema, blepharospasm, ptosis, third eyelid elevation, and positive corneal fluorescein staining. All CLEVOR-related observations resolved within 6 hours post-dosing. There was a dose dependent decrease in food consumption for dogs in the CLEVOR groups. Some dogs in the CLEVOR groups also had slight decreases in body weight. There were no effects on gross or microscopic pathology.
