Triprolidine hydrochloride (TPH) is chemically 2-[(1E)-1-(4methylphenyl)-3-(pyrrolidin-1-yl)prop-1-en-1-yl] pyridine (Figure 1). This is anti-allergic, Histamine H1 antagonist that blocks the action of endogenous histamine, which subsequently leads to temporary relief of negative symptoms brought on by histamine. It is used for the treatment of seasonal or perennial allergic rhinitis or non-allergic rhinitis, conjunctivitis, and mild urticaria and angioedema [1]. The most common side effects are sedation, dizziness, gastrointestinal disturbances, nausea, vomiting, and diarrhea. It may also produce blurred vision, dryness of mouth, tight of chest, blood disorders including agranulocytosis, and hemolytic anemia [2]. Literature survey revealed that few analytical methods have been reported for the determination of TPH in plasma using Thin-layer chromatography [3] simultaneous determination of TPH with other anti-histamines [4][5][6] other agents [7,8]. Few methods have been developed for the determination of triprolidine by highperformance liquid chromatography (HPLC) [9] and spectrophotometric method [10]. Spectrophotometric and HPLC [11] determination of TPH and its metabolite in biological samples using liquid chromatographymass spectrometry [12]. Capillary Zone Electrophoresis Method for Quality Control Analysis of TPH with other drugs [13] degradation studies of TPH and Stability indicating Ultra Performance Liquid Chromatography method [14]. New plastic membrane and carbon paste ion elective electrodes for the determination of triprolidine [15]. TPH is usually administered in combination with dextromethorphan and/or phenylpropanolamine and also with paracetamol [16].
