Hepatic and renal toxicities of indomethacin acid, salt form and complexed forms with hydroxypropyl‐β‐cyclodextrin on Wistar rats after oral administration

Indomethacin (IM), a non‐steroidal anti‐inflammatory drug, has the capacity to induce hepatic and renal injuries when administrated systemically. The aim of this study is to assess the IM absorption from complexed forms when orally administered to rats, by means of a comparative evaluation of its capacity to induce hepatic and renal injury in different forms, namely IM acid, IM sodium salt or IM complexed with hydroxypropyl‐β‐cyclodextrin (HP‐β‐CD), using freeze‐ and spray‐drying methods.
