MolnuFIP™ delivers pure EIDD-1931, the active antiviral metabolite of molnupiravir, in a formulation designed exclusively for feline physiology. By using EIDD-1931 directly—rather than modifying human molnupiravir capsules—MolnuFIP™ provides a more precise, consistent, and veterinary-appropriate approach to FIP care.

 

Purpose-Built Feline Formulation

Each MolnuFIP™ capsule contains 15 mg of EIDD-1931, equivalent in activity to approximately 66 mg of molnupiravir (EIDD-2801).

This formulation is optimized for:

 

  • Feline metabolic rate

  • Gastrointestinal absorption profile

  • Reliable dose–response performance

 

The result is accurate, predictable antiviral activity with reduced variability compared to human-intended products.

 

Proven Antiviral Potency

Published research demonstrates that:

 

  • EIDD-1931 exhibits up to 10× greater in-vitro antiviral potency compared with molnupiravir (EIDD-2801).

  • EIDD-1931 demonstrates 7.3× higher potency than GS-441524 under similar test conditions.

 

This potency advantage enables therapeutic efficacy at lower milligram doses, supporting improved tolerability and rapid clinical response.

  • Wet FIP (effusive)

  • Dry FIP (non-effusive)

  • Mixed or transitional presentations

 

Additional formulation benefits:

  • Optimized for feline metabolism and tissue penetration

  • Highly consistent blood-level performance

  • Designed to support low relapse incidence when used according to veterinary guidance

  • Scientifically grounded formulation

  • Consistent mg-per-kg dosing

  • No need to modify human medications

    Gengivoestomatite associada a Calicivirus

    No 3° dia o meu gato voltou a comer, a dor desapareceu. No 13° dia as lesões estavam reduzidas a 20%.

    Tratamento ainda em curso mas os resultados são surpreendentes.

    Depois de 1 ano passado em antibióticos, depo-medrol, extrações dentárias, em que nada resultou, o animal alimentado à seringa por recusa total em comer, com pânico da comida, das taças e de mim, este era o último recurso.

    Só lamento não ter tido conhecimento mais cedo do tratamento MolnuFip.

    Muito obrigada!
