Application field
1. Veterinary Clinical Cases: This is the core application scenario for GS441. For each cat diagnosed with FIP, the veterinarian will develop a medication regimen based on the specific condition. For example, if the cats has wet FIP and accompanied effusion, GS441 can reduce the effusion; for cat with dry FIP with organ damage, GS441 can inhibit viral replication to protect organs; for cats which have neurological FIP, it is better to use higher dose, and combining it with anti-inflammatory drugs, this can further enhance the treatment effect.
2. Pet Emergency Treatment Scenarios: When veterinary hospitals receive emergency cases of acute FIP, such as sudden large pleural effusion causing respiratory distress or acute neurological symptoms leading to seizures, this medication can serve as a core emergency treatment. Rapid administration by the veterinarian can quickly inhibit viral spread, alleviate critical symptoms, and buy time for subsequent symptomatic treatment such as effusion drainage, reducing the acute mortality rate of affected cats.
3. Animal Medical Research and Experiment Scenarios: Widely used in laboratories of universities, veterinary research institutions, and animal pharmaceutical companies. On the one hand, it can be used to study the pathogenesis of feline viral infection (FIP) caused by mutations in feline coronaviruses and to explore how drugs affect viral replication. On the other hand, it can also be used for experiments such as comparing drug efficacy and optimizing dosage. For example, by using treatment data of different dosages for different types of FIP, it can provide experimental evidence for improving clinical dosing standards and developing similar antiviral drugs.
