Oriheal Petvomi Fix Ondansetron Veterinary Antiemetic for Dogs & Cats
Oriheal Petvomi Fix is a veterinary prescription antiemetic formulation containing Ondansetron (as Ondansetron IP), a selective 5-HT3 (serotonin type 3) receptor antagonist, manufactured by Oriheal Lifesciences. Indicated for the management of nausea, vomiting, and emesis in dogs and cats associated with chemotherapy, gastroenteritis, post-operative recovery, uraemia, hepatic disease, and other conditions causing central or peripheral 5-HT3-mediated emesis. Available in three formulations: 4mg palatable tablets, 8mg palatable tablets, and 2mg/5ml oral suspension (60ml) for small patients and precise weight-based dosing.
Composition
-
Petvomi Fix 4mg Tablets: Ondansetron IP — 4mg per tablet
-
Petvomi Fix 8mg Tablets: Ondansetron IP — 8mg per tablet
-
Petvomi Fix 2mg/5ml Suspension: Ondansetron IP — 2mg per 5ml; 60ml bottle
Mechanism of Action
- Ondansetron selectively blocks 5-HT3 (serotonin type 3) receptors in the chemoreceptor trigger zone (CTZ), vagal afferents of the GI tract, and nucleus tractus solitarius — the primary peripheral and central pathways triggering nausea and vomiting in dogs and cats
- Does not block dopamine (D2) receptors — minimal sedation and extrapyramidal side effects compared to metoclopramide
Therapeutic Class
- Veterinary selective 5-HT3 receptor antagonist antiemetic prescription tablets and suspension for dogs and cats — nausea, vomiting, chemotherapy-induced emesis, and gastroenteritis management
Key Benefits
- Selective 5-HT3 antagonism — targeted antiemetic action at both central (CTZ) and peripheral (vagal GI) serotonin receptors; effective for both central and peripheral triggers of nausea and vomiting
- Chemotherapy-induced nausea and vomiting (CINV) — first-choice antiemetic for CINV in veterinary oncology; serotonin release from enterochromaffin cells is the primary mediator of CINV
- Gastroenteritis — effective for vomiting associated with acute and chronic gastroenteritis, parvoviral enteritis, and GI inflammation
- Post-operative and uraemic vomiting — controls emesis in hospitalised and post-surgical patients
- Palatable formulation — all three forms are designed for easy oral administration in dogs and cats
- Suspension (2mg/5ml / 60ml) — enables precise weight-based dosing; preferred for small dogs, cats, and puppies/kittens
Indications
- Chemotherapy-induced nausea and vomiting (CINV) in dogs and cats
- Acute and chronic vomiting associated with gastroenteritis and GI inflammation
- Post-operative nausea and vomiting
- Uraemic and hepatic disease-associated vomiting
- Parvoviral enteritis — supportive antiemetic care
- General nausea and emesis management where 5-HT3 pathway involvement is suspected
Directions for Use
- Administer orally as directed by a licensed veterinarian
- Dosage based on body weight and indication — typical veterinary dose: 0.1–0.2 mg/kg PO every 8–12 hours; confirm exact protocol from veterinary prescription
- Tablets: can be given with or without food; palatable formulation aids voluntary acceptance
- Suspension: shake well before use; measure accurately using dosing syringe; store in refrigerator after opening if directed on label
Safety Information
- Prescription medicine — for veterinary use only; administer under licensed veterinary supervision
- Ondansetron may prolong the QT interval — use with caution in patients with pre-existing cardiac arrhythmias or receiving other QT-prolonging drugs
- Use with caution in patients with hepatic impairment — Ondansetron is hepatically metabolised; reduce dose or frequency in severe hepatic disease
- Drug interactions — avoid concurrent use with apomorphine (may reduce apomorphine's emetic efficacy); consult veterinarian regarding concurrent medications
- Keep out of reach of children; store tablets in a cool, dry place away from direct sunlight; see suspension label for storage requirements
