Asia Pacific Isoxazoline Drugs Market Size

Isoxazoline is a relatively new chemical family of five-membered heterocyclic chemical compounds with one oxygen and one nitrogen atom next to each other. Isoxazoline compounds such as fluralaner, afoxolaner, sarolaner, and lotilaner are active components in tick repellents.

Ticks are non-flying insects that are parasites on dogs, cats, and other animals. The host must come into direct contact with a tick in order to become a parasite. Ticks are dangerous to pets because they transmit illnesses such as Lyme disease, Rocky Mountain spotted fever, ehrlichiosis, tularaemia, and STARI (Southern tick-associated rash illness). In order for illnesses to be transferred, a tick must remain attached to a host for several hours. To prevent tick bites in pets, a variety of repellents, insecticides, and growth inhibitors are commercially available.

The isoxazoline class of medicines are oral insecticides that have been approved for the treatment of ectoparasites in companion animals such as dogs and cats. These medications were initially introduced in 2013 as veterinary treatments for ticks and fleas in dogs. Several studies, however, have demonstrated their effectiveness against various veterinary and agricultural parasites. Bravecto, Credlio, Nexgard, and Simparica are examples of FDA-approved isoxazoline medications.

Innovations on current medications for new indications in oral and topical formulations, as well as increased awareness of ectoparasite prevention and control of fleas and ticks, are expected to drive market expansion. The market is divided into three sections: product type, pet kind, and geography.

Regional Analysis

In the market for isoxazoline drugs, Asia-Pacific is expected to have the largest share. During the forecast period, the market is expected to be propelled by rising adoption rates in countries such as India and China, as well as increased public awareness of pet care. Growing pet-care spending in India is expected to create plenty of opportunities. "The Indian animal healthcare industry is anticipated to reach approximately Rs. 5,500 crores (USD 770 million) (2020)," according to the Indian Federation of Animal Health Companies.

Companion animals account for around 5% of all animal healthcare spending. The paucity of isoxazoline producers in these areas also creates an opportunity for existing businesses. Furthermore, firms are aiming to have their treatments approved in India and China. Such characteristics are expected to present manufacturers with significant potential to increase their presence in these emerging countries.
