A liquid pharmaceutical suspension for oral administration containing a bismuth-containing pharmaceutical agent, a suspension system, and water. The suspension system can contain from about 0.001% to about 0.2% gellan gum and from about 0.001% to about 0.75% magnesium aluminum silicate.

Bismuth containing liquid pharmaceutical suspensions

A method of producing a liquid pharmaceutical suspension by mixing magnesium aluminum silicate, gellan gum, bismuth subsalicylate, and methyl cellulose.

Method for making bismuth containing liquid pharmaceutical suspensions

A paint containing a surfactant system capable of structuring a non-aqueous liquid composition, wherein the surfactant system comprises at least about 5% of a structuring particle. The surfactant system preferably further comprises a surfactant selected from the group consisting of anionic, nonionic, cationic, amphoteric surfactants and mixtures thereof. A well dispersed mixture of a non-aqueous liquid, for example, a nonionic surfactant, and at least about 25%, by weight of the surfactant system results in the mixture having a yield of at least about 2.0 Pa when measured at 20 sec and 25&deg; C. Moreover, the surfactant system should exhibit a peak when measured by SAXS x-ray diffraction, wherein the peak's center is between about the 1.5 to 2.5 v positions on the 2 theta axis. The structuring particles are most preferably structuring particles of sulfate and linear alkyl benzene sulfonate.
