Abstract The efficacy and safety of two different galenic formulations of transdermal clonidine systems were compared in 905 patients with mild to moderate essential hypertension during a 12 weeks observation period. 449 patients were treated with the matrix controlled clonidine transdermal (C-TD) system and 456 patients with the membrane controlled clonidine system (C-TTS). The mean blood pressure was reduced from 168/102 mmHg to 146/87 mmHg in the C-TD and from 169/102 mmHg to 148/88 mmHg in the C-TTS group. There was no difference in the response rate. The pattern of systemic side-effects appeared to correspond to those seen during oral clonidine treatment but with a lower frequency and intensity. The C-TD patch improved skin tolerability and the drop-out rate due to skin reactions was 2.2 times lower compared with the C-TTS group. Local skin reactions led to withdrawal in 35 of 449 C-TD treated and in 79 of 456 C-TTS treated patients. In conclusion, the improved carrier system for the transdermal clonidine treatment reduced local side-effects which in turn may further enhance acceptability and compliance in treated patients.
