| Abstract | ||
| The interaction between temazepam and b-cyclodextrin (b-CD) or hydroxypropyl b-cyclodextrin (HPb-CD) was studied in aqueous solution. The attempts made to obtain temazepam-cyclodextrin complexes in the solid state through freeze drying or slow evaporation under nitrogen of equimolar solutions of temazepam-CD failed to separate these inclusion compounds. On the other hand, co-grinding of temazepam with b-CD or HPb-CD although showed no evidence of formation of inclusion complexes, yet gave rise to very fast dissolution compared to non-treated temazepam or its physical mixtures with CD. Furthermore, the co-grinding of temazepam with Avicel PH 101 (microcrystalline ,cellulose) improved temazepam dissolution to nearly the same extent as those of b-CD or HPb- CD. | ||
