[Hypertension therapy with Briserin: what role do dihydroergocristine components play?].

40 patients with essential hypertension were subjected to an analysis of efficacy and safety of the three-component-combination Briserin (Reserpine, Clopamide, Dihydroergocristine). After double-blind and randomized allocation, one group received the two constituents Reserpine/Clopamide, another the full combination Briserin and a third first Reserpine/Clopamide and Briserin afterwards. Both types of treatment proved equi-effective in terms of blood pressure reduction with the blood pressure values falling below 150/90 mm Hg within one week. The most important finding resided in the improved orthostatic tolerance due to Briserin. Maximal systolic pressure drop during standing and the tachycardia associated were significantly reduced by Briserin, i.e. by the influence of Dihydroergocristine. In addition, there was a corresponding difference in terms of subjective complaints due to orthostasis. The same held true for general symptoms related to hypertension such as headache, dizziness, undue tiredness and sleeplessness. Patients preferred treatment with Briserin as compared to the other regimen. The discussion deals with the clinical-pharmacological impact of the orthostatic regulation quality within the framework of antihypertensive treatment.
