What is Ponazuril?
Origin and Primary Use
Ponazuril is an antiprotozoal medication derived from toltrazuril, developed to treat coccidiosis in various animals, including dogs, cats, and horses. It is particularly effective against Cystoisospora (formerly Isospora) species, the most common cause of coccidiosis in dogs.
How Ponazuril Works in Dogs
Ponazuril interferes with the metabolic processes of protozoa, disrupting their ability to reproduce and survive. By targeting the parasites’ cellular structures, it effectively eradicates the infection within a few days of administration.
Availability
Ponazuril is primarily available as a veterinary prescription medication, though some formulations may be found through compounding pharmacies. It is not an over-the-counter drug, meaning a veterinarian must prescribe the appropriate dosage for a dog’s specific condition.
Ponazuril Liquid Solution: What You Need to Know
Formulation and Concentration
Ponazuril liquid solution is commonly available in a 5% (50 mg/mL) concentration. This liquid form allows for precise dosing based on a dog’s weight, ensuring effective treatment.
How It Differs from Other Antiparasitic Treatments
Unlike traditional dewormers, which primarily target intestinal worms, Ponazuril is designed to combat protozoal infections. It provides faster relief and is often used as a single-dose treatment, compared to multi-day regimens required for some antibiotics and dewormers.
Storage and Handling
To maintain the effectiveness of Ponazuril liquid solution:
- Store at room temperature (59-86°F or 15-30°C).
- Keep away from direct sunlight and moisture.
- Shake well before use if required by the formulation.
- Always use a clean syringe or dropper for administration.
Ponazuril Dose for Dogs Chart
Standard Dosage Guidelines
The recommended Ponazuril dose for dogs is 5 mg per kilogram (2.27 mg per pound) of body weight.
Dosage Chart
| Dog’s Weight | Dosage (5 mg/kg) | Equivalent in 50 mg/mL Solution |
|---|---|---|
| 2 lbs (0.9 kg) | 4.5 mg | 0.09 mL |
| 5 lbs (2.3 kg) | 11.5 mg | 0.23 mL |
| 10 lbs (4.5 kg) | 22.7 mg | 0.45 mL |
| 20 lbs (9.1 kg) | 45.5 mg | 0.91 mL |
| 40 lbs (18.2 kg) | 91 mg | 1.82 mL |
| 60 lbs (27.3 kg) | 136 mg | 2.73 mL |
| 80 lbs (36.4 kg) | 182 mg | 3.64 mL |
| 100 lbs (45.5 kg) | 227 mg | 4.55 mL |
Example Calculation:
A 15 lb (6.8 kg) dog would require:
- 6.8 kg × 5 mg/kg = 34 mg Ponazuril
- 34 mg ÷ 50 mg/mL = 0.68 mL of liquid solution
Frequency and Duration of Treatment
- Standard Protocol: A single dose is often effective.
- Severe Cases: A second dose may be administered 24-48 hours later, as directed by a veterinarian.
- Puppies vs. Adults: Puppies may require closer monitoring due to immature immune systems.
Administration Tips
- Use an oral syringe for precise measurement.
- Administer directly into the mouth or mix with a small amount of food.
- Ensure complete ingestion—if the dog spits it out, do not redose immediately; consult your veterinarian.
