Application

Magnesium stearate has been used as a tablet and capsule lubricant. It has also been used for preparing microcapsules.

Biochem/physiol Actions

Magnesium stearate is the magnesium salt of stearic acid that possess lubricating properties and hence prevents ingredients from sticking to manufacturing equipment during the compression of chemical powders into solid tablets. Dry coating of drugs with magnesium stearate leads to flow improvement, flow-aid and lubrication effects, tabletability as well as non-inhibited dissolution rate.
