Proton pump inhibitors for the treatment of cancer in companion animals.
Abstract: The treatment of cancer presents a clinical challenge both in human and veterinary medicine. Chemotherapy protocols require the use of toxic drugs that are not always specific, do not selectively target cancerous cells thus resulting in many side effects. A recent therapeutic approach takes advantage of the altered acidity of the tumour microenvironment by using proton pump inhibitors (PPIs) to block the hydrogen transport out of the cell. The alteration of the extracellular pH kills tumour cells, reverses drug resistance, and reduces cancer metastasis. Human clinical trials have prompted to consider this as a viable and safe option for the treatment of cancer in companion animals. Preliminary animal studies suggest that the same positive outcome could be achievable. The purpose of this review is to support investigations into the use of PPIs for cancer treatment cancer in companion animals by considering the evidence available in both human and veterinary medicine.

This research article explores the potential of proton pump inhibitors (PPIs) for treating cancer in pets, using evidence from both human and veterinary medicine. PPIs affect the acidity of the cancerous environment, which can kill tumor cells, improve medicinal effectiveness, and reduce the spread of cancer.
Understanding Proton Pump Inhibitors (PPIs)
- Proton pump inhibitors (PPIs) are a class of drugs primarily used to treat gastrointestinal disorders such as ulcers and gastroesophageal reflux disease.
- These drugs function by reducing the production of stomach acid, which in turn helps to alleviate symptoms of these disorders.
- However, recent research has suggested that they may also have cancer-fighting properties.
The Role of PPIs in Cancer Treatment
- Cancer treatment often involves the use of chemotherapy, which unfortunately does not selectively target cancer cells and can result in numerous adverse side effects.
- It has been discovered that cancerous cells often have an altered acidity – a trait that PPIs can potentially exploit to target these cells specifically.
- By using PPIs, it’s possible to block the transport of hydrogen out of the cancer cell, which alters the extracellular pH levels. This alteration can lead to the death of tumor cells, a reduction in the resistance to drugs, and decreased cancer metastasis.
Potential for PPIs in Veterinary Medicine
- The results derived from human clinical trials suggest the potential viability of PPIs as a treatment option for cancer in companion animals.
- There have been preliminary studies conducted in animals that support this assertion, however the results are still early-stage and require further validation.
- Use of PPIs in treating cancer in pets is a relatively novel approach, and extensive research is needed to fully understand its efficacy, safety, and best practices.
- The aim of this review is to stimulate further research into the use of PPIs for cancer treatment in companion animals, stressing the importance of examining the existing available evidence in both human and veterinary medicine.
