Summary
The acute and long-term (6 months) effects of captopril (C) were studied in 23 patients with previously uncontrolled severe (DBP>120 mmHg) hypertension of different origin: essential (EH)n=10, renovascular (RVH)n=9, and renal (RH)n=4. In addition, four patients were treated with renal transplant artery stenosis and hypertension (TRVH), refractory to conventional therapy. Before treatment supine blood pressure (BP, mmHg) averaged: 205/131 (EH), 204/124 (RVH), 207/132 (RH) and 194/117 (TRVH). All patients received diuretics and other antihypertensive drugs, the dosages of which are expressed in arbitrary equivalent units (U) per day (UD=diuretics; UA=other antihypertensive drugs). Antihypertensive therapy before study:UD: EH 1.6; RVH 1.0;UA: EH 7.3; RVH 5.5. After admission, C dosage was increased from 25 mg to a maximum of 150 mg t.i.d. Antihypertensive treatment was reduced as far as possible. DBP decrease after 25 mg C was related to pretreatment PRA in RVH only. After 3 months of C treatment, BP decreased to 190/116 in EH and 145/89 in RVH (EH vs RVHP<0.01), 158/98 in RH, and 154/90 in TRVH. After 6 months, BP response was maintained in RH and TRVH. BP increased slightly in RVH to 158/102 mmHg, mainly because of impaired renal function in three patients with bilateral renovascular disease. In EH,BP decreased to 167/109, since three non-responders were taken out of the group. After 6 months, EH still received higher dosages of antihypertensive drugs than RVH. Acute and chronic hypotensive effects of C were not significantly correlated. Side-effects occurred in five patients: skin rash and pruritus [2], taste disturbances [1], proteinuria [1], and acute renal failure in one patient with TRVH. In our hands, captopril in combination with diuretics was significantly more potent in severe RVH than in EH. Dosages and side-effects of other antihypertensive drugs could be markedly reduced in most patients, which may improve long-term drug compliance.
Zusammenfassung
Akut- und Langzeitwirkungen (6 Monate) von Captopril (C) wurden bei 23 Patienten mit schwerer, unbehandelbarer (diast. Blutdruck >120 mmHg) Hypertonie unterschiedlicher Ätiologie untersucht: Essentielle (EH)n=10, renovaskuläre (RVH)n=9 und renale (RH)n=4, Hypertonie. Zusätzlich wurden 4 Patienten mit therapie-refraktärer Hypertonie und Nierentransplantatarterienstenose (TRVH) behandelt. Der Blutdruck (BP, mmHg) vor Therapie betrug im Mittel: 205/131 (EH), 204/124 (RVH), 207/132 (RH), 194/117 (TRVH). Alle Patienten erhielten Diuretika sowie andere Antihypertensiva, deren Dosierungen in Äquivalenzeinheiten (U) pro Tag angegeben werden (UD=Diuretika; UA=andere Antihypertensiva). Antihypertensive Therapie vor der Untersuchung:UD: EH 1.6; RVH 1.0;UA: EH 7.3; RVH 5.5. Nach der stationären Aufnahme erfolgte eine C-Therapie mit steigender Dosis von 25 mg auf maximal 150 mg dreimal/Tag. Die übrige antihypertensive Behandlung wurde so weit wie möglich reduziert. Der diastolische BP-Abfall nach 25 mg C stand nur bei RVH in Beziehung zur peripheren Reninaktivität (PRA). Nach 3 Monaten C-Therapie erfolgte ein BP-Abfall auf 190/116 bei EH und auf 145/89 bei RVH (P<0.01), auf 158/98 bei RH und auf 154/90 bei TRVH. Nach 6 Monaten war die Blutdrucksenkung bei RH und TRVH unverändert. In der Gruppe mit RVH kam es zu einem geringen BP-Anstieg auf 158/102, welcher vorwiegend durch die Nierenfunktionsverschlechterung bei 3 Patienten mit bilateraler Nierenarterienstenose bedingt war. In der Gruppe mit EH fiel der BP auf 167/109, da 3 „non-responder“ aus der Gruppe herausgenommen wurden. Nach 6 Monaten erhielt die Gruppe mit EH höhere Dosierungen von Antihypertensiva als Patienten mit RVH. Akut- und Langzeiteffekte von C waren nicht signifikant miteinander korreliert. Nebenwirkungen traten bei 5 Patienten auf: Hautexanthem und Juckreiz (2), Geschmacksstörungen (1), Proteinurie (1), akutes Nierenversagen bei einem Patienten mit TRVH. In der vorliegenden Untersuchung war Captopril in Kombination mit Diuretika bei schwerer RVH deutlich wirksamer als bei schwerer EH. Die Dosierung und Nebenwirkungen anderer Antihypertensiva konnte bei den meisten Patienten deutlich vermindert werden. Dadurch wird wahrscheinlich die Langzeit-Kompliance verbessert.
