M. Shahjahan et I. Islam, PRELIMINARY EVALUATION OF SHILAJIT AS A SUSPENDING AGENT IN ANTACID SUSPENSIONS, Drug development and industrial pharmacy, 24(11), 1998, pp. 1109-1112
The efficacy of shilajit, a gummy exudate of the plant Styrax officina
lis Linn (Family: Styraceae), was evaluated as a suspending agent for
the formulation of antacid preparations. Shilajit produced effects on
sedimentation volume similar to those produced by sodium carboxymethyl
cellulose (CMC), but at lower concentrations. it induced better flocc
ulation with a moderate increase in viscosity compared to CMC. It did
nor interfere with the acid-consuming capacity of the suspensions.
