What is Squalamine?

Squalamine is a chemical produced from the stomach and the liver of the spiny dogfish shark. Squalamine can also be made in the laboratory.

People take squalamine as an antibiotic to fight bacterial infections.

The lab-made version of squalamine is sometimes applied directly to the skin as an antibiotic.

Some researchers are studying squalamine to see if it might be effective against solid tumors in children. Other researchers are studying squalamine in combination with a prescription high blood pressure medication called captopril. They want to see if this combination is a good treatment for eye disease caused by diabetes.

Don't confuse squalamine with shark cartilage, which is prepared from the cartilage of spiny dogfish shark, hammerhead shark (Sphyrna lewini), and other shark species.
