Additionally, Amifostine has been found to reduce the radiation damage to normal lung tissue in certain breast cancer patients (Hensley, 2018).

Administration

Amifostine is administered intravenously and is rapidly cleared through vascular permeation. The drug is hydrolyzed in the plasma, producing its active metabolite, WR-1065.

This metabolite is transported into the cells, where it is activated by enzymes, including aldehyde dehydrogenase. After activation, WR-1065 helps protect the cells from oxidative stress by scavenging free radicals and stimulating antioxidant enzymes.

The dose of Amifostine used depends on the type of chemotherapeutic agent used in the treatment and can range from 400-1500 mg/m.

Amifostine Working Principle

Amifostine works by reducing the side effects of cancer treatments and promoting the body’s natural ability to repair DNA. The drug acts as a free radical scavenger, which reduces the production of reactive oxygen species (ROS) that cause DNA damage and cell death (Kikuchi, 2021).

When cellular ROS levels are reduced, it increases the cellular ability to survive under conditions of hypoxia and promotes enhanced genetic expression.

Due to its potent antioxidant properties, Amifostine helps to prevent and repair DNA damage in healthy cells, which can be caused by radiation and chemotherapy (Vranic, 2016).

Additionally, the drug can boost the activity of antioxidant enzymes such as catalase, superoxide dismutase, and glutathione peroxidase, which help to protect the cells from further damage. Amifostine has been shown to reduce the side effects of cisplatin, which is a chemotherapy drug used in the treatment of cancers such as ovarian cancer.

Cisplatin can damage the inner ear hair cells, which can lead to hearing loss. Amifostine has been demonstrated to significantly reduce cisplatin-induced ototoxicity by scavenging free radicals before they cause any damage to cellular components (Meyers, 1997).

Conclusion

In summary, Amifostine is a cytoprotective drug that reduces the side effects of chemotherapeutic agents and radiation. The drug helps the body to repair DNA damage caused by ROS, hypoxia, and chemotherapy.

By stimulating the activity of antioxidant enzymes and scavenging free radicals, Amifostine can mitigate the toxicity of platinum-containing chemotherapeutic agents such as cisplatin.
