Alginate-diltiazem hydrochloride beads: optimization of formulation factors, in vitro and in vivo availability.

Alginate beads containing diltiazem hydrochloride (DTZ) were prepared by the ionotropic gelation method. The effects of various factors (alginate concentration, additives type, calcium chloride concentration and curing time) on the efficiency of drug loading were investigated. The formulation containing a mixture of 0.8% methylcellulose (MC) and 4% alginate cured in 2% calcium chloride for 6 h ...

Evaluation of furosemide-loaded alginate microspheres prepared by ionotropic external gelation technique.

Alginate microspheres containing furosemide were prepared by the ionotropic external gelation technique using Ca2+, Al3+ and Ba2+ ions. The incorporation efficiency of the prepared microspheres ranged between 65% and 93%. The effect of sodium alginate concentration, cross-linking ions and drying conditions was evaluated with respect to entrapment efficiency, particle size, surface characteristi...
