Pharmacology of Molnupiravir. Molnupiravir is a prodrug that is metabolized to the cytidine nucleoside analogue N(4)-hydroxycytidine (NHC). Intracellularly, NHC is phosphorylated into the active triphosphate (NHC-TP), which is incorporated into FIP RNA, resulting in an accumulation of errors in the viral genome that leads to inhibition of viral replication. 1 Molnupiravir and NHC have “The present study describes a very substantial cohort of 307 cats with a presumed or confirmed diagnosis of FIP treated using specific regulated veterinary compounded nucleoside analogues of known composition in countries where these products can be legally prescribed by veterinary surgeons to cats under their carein the present study, all three treatment protocols (ie, remdesivir alone cats (gabapentin for analgesia in cats = 5 – 10 mg/kg or 25 – 50 mg per cat, PO, BID) • The use of pre-hospital gabapentin has been the single most effective tool for reducing fear and anxiety in healthy cats that I and many clinicians have used. • Expect that cats will be ataxic and slow but not overtly sedate on this dose of gabapentin. Prior to February 2019, feline infectious peritonitis was a guaranteed death sentence to cats. Thanks to a lifetime of dedication and devotion, Dr Niels Pedersen of UC Davis discovered the cure for FIP: the nucleoside analog GS-441524, also referred to as “GS”. Considered an almost routinely fatal disease until the development of this unique compound in 2018, GS-441524 has been shown to be a safe and effective therapy for the treatment of FIP in cats in a number of clinical trials carried out primarily in Australia and the UK. Feline-friendly formulations prescribed by veterinarians for the treatment of Feline Infectious Peritonitis (FIP). Learn More Cats: the connoisseurs of comfort and perhaps the most opinionated patients in the animal kingdom. In cats, gabapentin is most often used as a pain medication for chronic pain, such as from arthritis. Gabapentin is also recognized as beneficial in reducing the fear responses that a kitty may have to the stress of handling and being examined at the vet. Historically, three major pharmacological approaches have been employed to treat FIP: (1) immunomodulators to stimulate the patient’s immune system non-specifically to reduce the clinical effects of the virus through a robust immune response, (2) immunosuppressive agents to dampen clinical signs temporarily, and (3) re-purposed human antiviral d Very young kittens, cats older than 10 with comorbidities that result in isosthenuria, immunocompromised cats, and cats that have been previously catheterized or have polyuria. A 3-year-old male cat with hematuria that vocalizes when he's urinating is highly unlikely to have a UTI, and he doesn't need antibiotics. Long-term use of corticosteroids with GS is strongly discouraged as it can mask improvement signs caused by the GS, especially in cats with neurological FIP, it has no curative power, and may interfere with the development of a protective immune response to the FIP virus. #2 Ask your vet for a prescription of gabapentin. This is a very safe medication with a wide dosing range. Dosing typically starts at 25mg – 50mg. Please confirm with your vet and treatment advisor. This will help calm your kitty before the injections and reduce pain. It is recommended to give gabapentin 1-2 hrs before each injection. 441524 for treatment of cats with naturally occurring feline infectious peritonitis. J. Feline Med. Surg. 2019, 21, 271–281 5. Dickinson PJ, Bannasch M, Thomasy SM, et al. Antiviral treatment using the adenosine nucleoside analogue GS-441524 in cats with clinically diagnosed neurological feline infectious peritonitis. NB: The sedative dose (>20 mg/kg) is higher than the analgesic dose of gabapentin in cats (gabapentin for analgesia in cats = 5 – 10 mg/kg or 25 – 50 mg per cat, PO, BID) The use of pre-hospital gabapentin has been the single most effective tool for reducing fear and anxiety in healthy cats that I and many clinicians have used. The Research FIP was considered fatal until the discovery of GC-376 and GS-441524, which can be used to treat this condition. 1. This prospective case series investigated the survival and clinical course of 28 cats with FIP administered compounded remdesivir (a prodrug of GS-441524) as monotherapy, with some cats transitioning to compounded oral GS-441524. A mild pain medication, Gabapentin, can be given orally prior to the injection to prevent pain. However, most cats using GS injections tolerate the treatment and do not need any pain medication or sedative.
