Milbemycin Oxime

## Milbemycin Oxime (CAS 129496-10-2): Key Functions and Uses

1. **Veterinary Antiparasitic Agent**
Milbemycin Oxime is a semi-synthetic macrocyclic lactone used primarily in veterinary medicine. It provides broad antiparasitic activity against susceptible internal parasites affecting companion animals.

2. **Heartworm Disease Prevention**
In approved veterinary formulations, Milbemycin Oxime helps prevent heartworm disease caused by immature stages of *Dirofilaria immitis*. Regular administration according to the product label can interrupt parasite development before adult heartworms become established.

3. **Control of Gastrointestinal Nematodes**
Depending on the animal species and approved formulation, it is used to control or remove susceptible gastrointestinal worms, including **roundworms, hookworms, and whipworms** in dogs and cats.

4. **Mechanism of Antiparasitic Action**
Milbemycin Oxime acts on parasite ligand-gated ion channels, including glutamate-gated chloride channels. This disrupts nerve and muscle signaling, leading to paralysis and elimination of susceptible parasites.

5. **Companion-Animal Health Applications**
The active ingredient is incorporated into veterinary products for dogs, puppies, cats, and kittens. Some combination products pair Milbemycin Oxime with other active ingredients to broaden parasite coverage, such as adding tapeworm control or flea-management effects.

6. **Research and Pharmaceutical Development**
CAS 129496-10-2 is used in veterinary pharmacology, antiparasitic drug development, formulation research, analytical testing, pharmacokinetic studies, and investigations of parasite susceptibility and resistance.

7. **Quality and Procurement Considerations**
When sourcing Milbemycin Oxime, buyers should verify identity, purity, assay, isomer or composition profile, residual solvents, particle size, certificate of analysis, storage conditions, and target-species approvals. Useful SEO keywords include **Milbemycin Oxime, CAS 129496-10-2, veterinary antiparasitic, macrocyclic lactone, heartworm prevention, roundworm control, hookworm treatment, whipworm control, and pet parasite medicine**.

8. **Important Veterinary and Safety Notice**
Milbemycin Oxime should be used only in approved veterinary formulations and at label-directed doses under professional guidance. Product suitability may vary by species, age, weight, health status, and parasite infection. Research-grade material is for laboratory use only and is not intended for self-medication, unauthorized animal treatment, food, or household applications.
