From the Guidelines
Crofelemer is not recommended for use in adult cattle due to its specific approval and use in humans, particularly for non-infectious diarrhea in HIV/AIDS patients, and the lack of research on its safety and efficacy in cattle. The medication is derived from the latex of the Croton lechleri plant and is not indicated for veterinary use, especially in ruminants like cattle, which have a different digestive system compared to humans 1.
When considering treatments for diarrhea in adult cattle, it's crucial to consult a veterinarian to determine the underlying cause, which could be parasitic, bacterial, viral, or dietary in nature. Appropriate treatments might include oral electrolyte solutions to manage dehydration, probiotics to restore gut flora, or antibiotics if a bacterial infection is confirmed 1.
Key points to consider in managing diarrhea in adult cattle include:
- The importance of a proper diagnosis to guide treatment
- The use of supportive care such as fluid therapy and dietary adjustments
- The potential need for targeted medications based on the cause of the diarrhea
- The unsuitability of crofelemer due to its human-specific indication and the lack of data on its use in cattle
Given the physiological differences between humans and cattle, and the absence of studies supporting the use of crofelemer in veterinary medicine, especially in adult cattle, the most appropriate course of action is to follow established veterinary guidelines and consult with a veterinarian for personalized advice on treating diarrhea in cattle.
From the Research
Crofelemer and Adult Cattle
There is limited information available on the use of crofelemer in adult cattle. However, some studies have investigated the use of crofelemer in calves and other animals.
Studies on Calves
- A study published in 2015 2 investigated the effect of crofelemer extract on experimentally induced enterotoxigenic Escherichia coli diarrhea in newborn Holstein calves. The results showed that the enteric-coated formulation of crofelemer extract significantly increased fecal dry matter in the calves.
- The study suggests that crofelemer may be effective in treating secretory diarrhea in calves, but more research is needed to confirm its efficacy in adult cattle.
Mechanism of Action
- Crofelemer is a first-in-class antidiarrheal agent that targets two distinct channels, the cystic fibrosis conductance regulator and calcium-activated chloride channel, responsible for chloride and fluid secretion in the GI tract 3, 4, 5.
- It has been shown to be effective in treating secretory diarrhea in humans, particularly in patients with HIV-associated diarrhea 5, 6.
Limitations
- There are no studies available that specifically investigate the use of crofelemer in adult cattle.
- More research is needed to determine the efficacy and safety of crofelemer in adult cattle.
