This modification of the morphine molecule results in a drug with higher lipid solubility and ability to cross the blood-brain barrier and therefore more rapid and complete central nervous system penetration, with the result that hydromorphone is somewhat faster-acting and about eight times stronger than morphine and about three times stronger than heroin on a milligramme basis.
