GS-441524 is a plasma metabolite of the antiviral prodrug remdesivir that has a half-life of 24 hours in humans. It has been found to be effective in fighting off feline coronavirus strains, responsible for the lethal disease feline infectious peritonitis (FIP), in in vitro tests.
FIP is caused by an immune defect or deficiency which causes white blood cells to replicate the virus as opposed to fighting it. Those cats whose immune system is not able to fight the virus, develop into wet FIP, while those who have a partial immune response develop dry FIP.
GS441524 is a nucleoside analog that acts as an alternative substrate and chain terminator. In simple terms, it interrupts the chain reaction of the virus, stopping its replication. This powerful nucleoside is proving to be a promising drug in combating this deadly infection in cats.

Feline Infectious Peritonitis (FIP) is a fatal viral disease in cats caused by a mutation of the feline coronavirus (FCoV). While most cats infected with FCoV do not develop FIP, in some cases, the virus mutates and triggers an abnormal immune response, leading to FIP.
FCoV is common in multi-cat environments like shelters and catteries. The virus is primarily transmitted through fecal-oral contact, where cats ingest the virus from contaminated surfaces, litter boxes, or grooming each other.
Diagnosing FIP is challenging and often involves a combination of clinical signs, laboratory tests, and ruling out other diseases. Common diagnostic steps include:
1. Blood tests: Elevated protein levels, high white blood cell count, and low albumin-to-globulin ratio.
2. Imaging: Ultrasound or X-rays to detect fluid accumulation.
3. Fluid analysis: Testing the fluid from the abdomen or chest for elevated protein levels and specific cell types.
4. Biopsy: Histopathological examination of affected tissues can provide a definitive diagnosis.
Recommended dosage: 10mg/KG * body weight kg
Taking time: Both taken before and after meals is ok. It is recommended to take it at a fixed time every day.
Taking method: Take it directly. If the cat does not eat it, it can also be mixed in the feed.
Storage: Store at room temperature or Store at 2~4 ° C. Avoid light. Shelf life is one year.
Recommended treatment for 12 weeks.
1. Introduction to the drug
Ingredients: GS441524 is a nucleoside analog that works by inhibiting viral RNA polymerase.
Indications: Mainly used to treat feline infectious peritonitis (FIP), especially wet and dry FIP.
2. Usage
Dosage: The dosage is usually calculated based on the cat's weight. The general recommended dose is 4-10 mg/kg per day. The specific dosage should be adjusted by the veterinarian based on the cat's condition and response.
Dosage frequency: Usually once a day for at least 12 weeks. Severe cases may require longer treatment.
Dosage: The tablets should be fed directly to the cat or mixed into a small amount of food to ensure that they are completely swallowed.
3. Side effects
Common side effects: May include symptoms such as loss of appetite, nausea, vomiting, and fatigue.
Serious side effects: Rare, but may include abnormal liver and kidney function. Regular blood tests are required to monitor the cat's health.
4. Precautions
Regular check-ups: During treatment, it is recommended to take the cat to the veterinarian for regular check-ups to ensure that the treatment is effective and no serious side effects occur.
Storage Conditions: The tablets should be stored in a dry, cool place away from direct sunlight and high temperatures.
