Film dosage forms (FDs) containing valsartan (VST), a popular antihypertensive drug, were prepared using a casting method with sodium alginate and other polysaccharides as the film base. Drug dissolution profiles of the FDs were investigated in limited medium. The FDs were 170-200 μm thick and were easy to handle. All FDs immediately swelled and disintegrated in the medium. About 23% of the VST...
Supercritically dried aerogels of several polysaccharides (chitin, chitosan, alginate, alginic acid, kcarrageenan, andagar) havebeencharacterisedbyphysisorptionofN2. Surface areas ashighas570m g have been measured. The nature of the functional groups of the polysaccharide significantly influences the adsorption of N2 on the surface of the aerogel. The net enthalpy of adsorption increases with t...
