[Undesirable effects and interaction to angiotensin converting enzyme inhibitors therapy].

UNLABELLED

By their intervention upon the mechanisms regulating the vascular tone, renal plasma flow and direct actions of chemical structures, angiotensin-converting enzyme (ACE) inhibitors may determine undesirable effects. These effects formed the object of a 5-year retrospective study (1995-1999) carried out at the IIIrd Medical Clinic of Iasi. During this interval ACE inhibitors were administrated to 2178 patients with hypertensive and coronary disorders or heart failure of various causes. Different generations of ACE inhibitors were used, but captopril, enalapril and lysinopril were the most commonly administered. Undesirable effects were recorded in 161 patients (7.3%). The following side-effects, single or associated, were recorded: 38 patients (23.6%) had increasing blood pressure proportional with ACEI dose, 80 patients (49.7%) had decreasing blood pressure at low doses ACEI, 23 patients (14.4%) had kidney failure, 2 patients (1.2%) had both increasing blood pressure and kidney failure, 3 patients (1.9%) had both decreasing blood pressure and kidney failure, 6 patients (3.8%) had dry cough, one patient (0.6%) had kidney failure with decrease blood pressure and allergic dermatitis, 4 patients (2.4%) had allergic dermatitis, and 4 patients (2.4%) had headache, vertigo, paresthesia.

CONCLUSIONS

The treatment with ACE inhibitors has to be carefully initiated under strict clinical and biological monitoring, preferably in hospital setting. No drug associations that favor the undesirable effects of ACE inhibitors were reported.
