[Thin layer analysis of talinolol (Cordanum) in urine--a screening method for monitoring of drug compliance in hypertensive patients].

: A simple and rapid analytical method for TLC detection of talinolol (Cordanum) is described. Because of its low technical expense it can be used for routine application in clinical laboratories. Triamteren (substance of contents of Triampur comp.) is detected simultaneously. This method has till now been applied to urine specimens of 145 hypertensive patients taking talinolol (n = 95) and triamteren (n = 50). The spectrofluorimetric analysis of talinolol was used as a reference method (r = 0.95).
