A heparin salt having a reduced sodium content being essentially sodium free and having a selectively high calcium or other selected salt content. A process for making these heparin salts by reaction with the selected metal salt, including, optionally, dialysis or precipitation. A typical heparin salt is a calcium heparin essentially free of sodium (like containing less than about 1% by weight of sodium), or mixed calcium-sodium heparin with a limited, predetermined content of sodium. Drug compositions containing these heparin salts and a pharmaceutical carrier. The drugs made from these heparin salts are useful as anti-coagulants.
