Alkaline phosphate is not a disease or a condition and therefore no medicine can "cure" it. Alkaline phosphate is an enzyme found throughout the body. Most common sites are liver, bone, placenta, and intestines. Each source of alkaline phosphate has a slightly different version of it called an isoenzyme. Blood tests can specifically test alkaline phosphate's isoenzyme to determine the source of that specific alkaline phosphate.
Alkaline phosphate can be elevated during normal moments of life such as healing broken bones, pregnancy and growth spurts in children.
However an elevated alkaline phosphate can also signal several problems including types of cancer. Bone and liver problems are the most common illnesses that increase alkaline phosphate but it is also elevated in germ cell tumors, viral hepatitis, inflammatory bowel disease (IBS), and mono.
Several medications can alter the alkaline phosphate levels as well such as birth controls, certain antibiotics, some antidepressants, and some diabetic medications.
