Bayer Negasunt Powder 20g is a specially formulated powder designed for veterinary use, providing a convenient way to apply antibacterial treatment to wounds. Veterinarians prescribe this product for various conditions, such as wounds affected by maggots, foot lesions associated with FMD (Foot-and-Mouth Disease), surgical wounds, accidental wounds, and navel infections.

What Is Negasunt?

Negasunt Powder ingredients (Coumaphos and Propoxur) are substances that directly inhibit the activity of acetylcholinesterase (AChE), an enzyme responsible for breaking down the neurotransmitter acetylcholine in the body. By inhibiting AChE, these compounds cause a buildup of acetylcholine in the spaces between nerve cells, leading to continuous stimulation of cholinergic receptors in both the central and peripheral nervous systems. This prolonged stimulation prevents the normal termination of nerve signals, resulting in excessive excitation and severe disruption of normal bodily movements in parasites. Ultimately, this paralysis induced by overstimulation leads to the parasites’ rapid death.

On the other hand, sulfanilamide acts as a competitive inhibitor of a bacterial enzyme called dihydropteroate synthetase, which utilizes a substance called para-aminobenzoic acid (PABA) for synthesizing essential folic acid. By inhibiting this enzyme, sulfanilamide interferes with the bacteria’s ability to produce folic acid, which is crucial for their replication and survival. Without folic acid, bacterial replication becomes impossible.

In summary, the combination of these ingredients offers an effective approach for treating various types of wounds in animals while combating bacteria and parasites through different mechanisms of action.


Negasunt powder content is as follows:

  • Coumaphos 3%;
  • Propoxur 2%;
  • Sulfanilamide 5%.

Coumaphos is an organophosphate insecticide used in veterinary medicine to control external parasites such as ticks, lice, and mites.

Propoxur is a carbamate insecticide that controls various external parasites in pets, including fleas and ticks. It is commonly found in some dog and cat flea and tick control products.

Sulfanilamide is an antibiotic belonging to the sulfonamide class. It has antimicrobial properties and is used in human and veterinary medicine to treat certain bacterial infections.

Forms of Negasunt

It is available in two different forms.


It is formulated as a powder, which is manufactured for convenient application. The powdered form allows for easy dusting onto the affected area. Veterinarians prescribe this powder to treat conditions such as maggot-infested wounds, foot lesions related to FMD (Foot-and-Mouth Disease), surgical wounds, accidental wounds, and navel infections in animals.


The best Negasunt spray for maggots formulation provides a convenient way to apply the product to the affected area. This form may be preferred for situations where a direct spray application is more suitable or when it is challenging to use the powdered form. Veterinarians also prescribe aerosol from Bayer for dogs for the same conditions mentioned earlier.


What is Negasunt powder used for?

In veterinary medicine, it is typically used to treat certain animal conditions. It is specifically formulated for convenient application as an antibacterial wound dressing. Here are some situations where this powder may be used:

  • Maggoted wounds: When animals have wounds infested with maggots, this product can be applied to help eliminate the maggots and treat the underlying wound.
  • Foot lesions associated with FMD (Foot-and-Mouth Disease): FMD can cause painful and debilitating foot lesions in animals. It can be prescribed by veterinarians to aid in the treatment of these lesions.
  • Surgical wounds: After surgical procedures, the powder can be used as a part of the wound care regimen to prevent or treat bacterial infections and promote healing.
