“…Several high-performance liquid chromatography methods have been developed for measuring hydrochlorothiazide concentration in pharmaceutical preparations (European Pharmacopoeia, 2002;Daniels and Vanderwielen, 1981;Stewart and Clark, 1986;Kartal and Erk, 1999;Zecevic et al, 2000;Hertzog et al, 2002;Jonczyk and Nowakowska, 2001).…”

“…Various analytical methods such as HPLC [9][10][11][12], differential pulse voltameter [13], stability indicating determination [14], photometric determination of HCTZ [15] were reported. BF is official in USP [16], whereas HCTZ is official in USP, IP [17] and BP [18].…”

“…However, an additional unknown degradate was detected after 16 h in either 0.1 N HCl or 0.1 N NaOH solution. 5 Thomas et al 6 reported analysis of bulk HCTZ by micellar electrokinetic capillary chromatography, and found three unknown peaks, which were not identi®ed in their work.…”

“…Deppeler 4 found that solid forms of HCTZ could be stored at ambient temperature for 5 years without evidence of degradation. Stress testing of HCTZ, 5 either 3 months at room temperature (10 mg HCTZ/mL methanol) or 4 days at 1008C (dry powder HCTZ), yielded only the degradate DSA. However, an additional unknown degradate was detected after 16 h in either 0.1 N HCl or 0.1 N NaOH solution.…”
