Largely known as a growth factor receptor antagonist Suramin is currently only used in the treatment of river blindness (onchocerciasis) as well as African sleeping sickness (trypanosomiasis). This medication is not approved by the USA FDA, but it is on the World Health Organization’s List of Essential Medicines. Unfortunately, it is not absorbed through the stomach or intestines, so ingesting it will unfortunately not provide the terapeutic that you are hoping for.
