| Pharmacodynamic Properties |
Mode of Action: Closantel uncouples oxidative phosphorylation in parasite mitochondria, leading to a disruption of ATP production. This results in energy depletion and parasite death. Spectrum of Activity: Effective against adult and immature stages of Fasciola hepatica (liver fluke). Active against certain gastrointestinal nematodes (e.g., Haemonchus contortus). Effective against blood-sucking ectoparasites such as ticks, mites, and lice. Onset & Duration: Provides long-lasting activity due to strong binding to plasma proteins, particularly albumin. |
| Storage | Store in a tightly sealed container. Keep in a cool, dry place away from light. Recommended storage temperature: below 25 °C. |
| MSDS | Provide as per request after the order or contract is signed. |
