Product Introduction
GS-441524 is a nucleoside analogue antiviral compound widely referenced in veterinary discussions related to the management of feline infectious peritonitis (FIP). As antiviral treatment approaches for FIP have continued to develop, oral tablet formulations have become an increasingly practical option for cats that require long-term treatment support.
This product contains 40mg GS-441524 per tablet and is designed for oral administration in cats undergoing FIP management programs. Compared with injectable formulations, tablets provide a convenient alternative for caregivers who prefer non-injection administration during maintenance or extended treatment cycles.
Feline infectious peritonitis is caused by a mutated form of feline coronavirus. Once the virus spreads systemically, it may affect organs throughout the body and trigger severe inflammatory responses. Depending on the progression of the disease, symptoms may involve fluid accumulation, organ inflammation, eye problems, or neurological complications.
GS-441524 works by interfering with viral RNA replication inside infected cells. By reducing viral reproduction, the compound helps lower viral activity and supports immune system recovery during treatment.
The tablet formulation is manufactured under controlled production standards and packaged for stable storage and convenient daily dosing.

About Feline Infectious Peritonitis (FIP)
Feline infectious peritonitis is one of the most challenging viral diseases in feline medicine. The disease develops when feline coronavirus mutates within the cat’s body and gains the ability to spread systemically.
Veterinary professionals generally classify FIP into several forms:
Wet (Effusive) FIP
Wet FIP commonly involves fluid accumulation in the abdomen or chest cavity. Symptoms may include abdominal swelling, lethargy, and breathing difficulty.
Dry (Non-effusive) FIP
Dry FIP often affects internal organs such as the liver, kidneys, or lymph nodes without obvious fluid buildup.
Ocular FIP
Eye-related symptoms may include inflammation, discoloration of the iris, or visual impairment.
Neurological FIP
When the nervous system is affected, symptoms such as tremors, balance problems, or behavioral changes may occur.
Different forms of FIP may require different antiviral dosage strategies and treatment durations.
Reference Dosage Information
GS-441524 dosage is generally calculated according to the cat’s body weight and clinical condition. Oral tablet administration is commonly adjusted to match injectable protocol equivalents.
Reference dosage guidelines commonly used in FIP treatment programs include:
| Condition |
Suggested Dosage |
| Wet FIP |
Based on body weight and antiviral protocol |
| Dry FIP |
Higher dosage may be required compared with wet FIP |
| Ocular / Neurological FIP |
Increased antiviral support may be necessary |
| Recurrence Cases |
Dosage adjustment may be recommended |
Treatment duration and dosage adjustments should be determined according to veterinary guidance and ongoing clinical monitoring.
Advantages of Oral GS-441524 Tablets
Convenient Daily Administration
Oral tablets provide an alternative to injectable treatment and may reduce stress for both cats and caregivers during long-term therapy.
Stable 40mg Strength
Each tablet contains 40mg GS-441524, allowing consistent dosage calculation and easier administration planning.
Suitable for Long-Term Treatment Programs
Many FIP management plans require several weeks of antiviral therapy. Tablet formulations may improve convenience during extended treatment cycles.
Reduced Injection Stress
Some cats experience discomfort or skin irritation from repeated injections. Oral administration may help improve treatment compliance in these situations.
Room Temperature Storage
The tablets can be stored at room temperature under recommended conditions, simplifying transportation and daily storage management.
Typical Application Scenarios
Veterinary Clinics
Veterinarians may incorporate GS-441524 tablets into FIP treatment programs, especially during maintenance stages or when oral administration is preferred.
Animal Rescue Organizations
Rescue groups caring for multiple cats may choose oral formulations to simplify treatment routines for recovering animals.
Breeding Facilities
Breeders managing cats under veterinary supervision may use oral antiviral support when long-term administration is required.
Home Care Treatment
Some caregivers prefer tablet administration because it may be easier to manage compared with daily injections, particularly for stable cats continuing treatment at home.
