Non aqueous titration may be used to determine the percentage purity of weak bases or weak acid drugs. Such drugs include H1 Antihistamines such as LOR.

Amphiprotic solvents are used to act as a medium. CH3COOH forms an onium ion intermediary with HClO4 which readily donates a proton to LOR.The endpoint is determined by potentiometry or using indicators such as crystal violate.
