Telmisartan (TS) have developed for the treatment of hypertension as the angiotensin II receptor blocker. TS belongs to class II drug in BCS classification and it has good permeability. But, it is poorly water soluble. Biological half-life of TS is 24 hours because it has not good bioavailability (only 42∼58%). The absorption of a drug is often limited by dissolution rate. Drug dissolution is important factor to the therapeutic efficacy of a medicine. Therefore, TS requires alternative...

Hecogenin acetate (HA) is an acetylated sapogenin that has shown potential antihyperalgesic activity, inhibiting descending pain and acting in opioid receptors. However, HA exhibits poor aqueous solubility, which may limit its application. This study aims to develop amorphous solid dispersions (ASD) using five hydrophilic polymers, to characterize them and to evaluate their antihyperalgesic activity.
