Enalapril worldwide experience.

Abstract

Overall, the worldwide experience on enalapril to date is very encouraging. The drug produces good to excellent responses in 54 to 66 percent of patients with essential hypertension and is at least as effective as either diuretics or beta blockers. The effects of enalapril compared with those of diuretics confirm that patients more dependent upon the renin-angiotensin system respond better. When hydrochlorothiazide is administered concomitantly with enalapril, almost all patients respond, with good long-term maintenance. In patients with severe hypertension, Blocadren or Aldomet may be added in addition to hydrochlorothiazide and will produce additional benefit. Enalapril attenuates the adverse metabolic effects of hydrochlorothiazide, particularly hypokalemia. Overall, although the efficacy of enalapril and that of captopril are similar, enalapril is better tolerated and does not appear to be associated with any significant occurrence of captopril-type side effects, particularly the skin rash and loss of taste. As expected, enalapril and other converting inhibitors may be associated with azotemia in patients with bilateral renovascular hypertension.

Rapid quantification of lisinopril in human plasma by liquid chromatography/tandem mass spectrometry.

An assay based on protein precipitation and liquid chromatography/tandem mass spectrometry (LC-MS/MS) has been developed and validated for the quantitative analysis of lisinopril in human plasma. After the addition of enalaprilat as internal standard (IS), plasma samples were prepared by one-step protein precipitation using perchloric acid followed by an isocratic elution with 10 mm ammonium acetate buffer (pH adjusted to 5.0 with acetic acid)-methanol (70:30, v/v) on a Phenomenex Luna 5 mu C(18) (2) column. Detection was performed on a triple-quadrupole mass spectrometer utilizing an electrospray ionization (ESI) interface operating in positive ion and selected reaction monitoring (SRM) mode with the precursor to product ion transitions m/z 406 --> 246 for lisinopril and m/z 349 --> 206 for enalaprilat. Calibration curves of lisinopril in human plasma were linear (r = 0.9973-0.9998) over the concentration range 2-200 ng/mL with acceptable accuracy and precision. The limit of detection and lower limit of quantification in human plasma were 1 and 2 ng/mL, respectively. The validated LC-MS/MS method has been successfully applied to a preliminary pharmacokinetic study of lisinopril in Chinese healthy male volunteers.

Renin-induced hypertension in Wilms tumor patients.

BACKGROUND: Since the report that hypertension associated with Wilms tumor (WT) may be renin-induced, no larger series than 13 patients have been published. Nevertheless, angiotensin converting enzyme (ACE) inhibitors have become treatment of choice for hypertension in WT patients. The purpose of this study was to investigate the correlation between plasma renin levels and blood pressure in a larger cohort of WT patients. PROCEDURE: In this retrospective, single-center study, data on blood pressure and plasma renin were analyzed in 86 WT patients treated according to the consecutive SIOP protocols 6, 9, 93-01, and 2001. RESULTS: At diagnosis, 47 WT patients suffered from hypertension (55%). In 31 of these patients plasma renin levels were analyzed; increased plasma renin levels were found in 25/31 patients (81%). In contrast, normal plasma renin levels were measured in 8/13 of the patients with a normal blood pressure (P = 0.012). Twenty-eight children received antihypertensive treatment before surgery, in 25 of them blood pressure normalized before surgery. Blood pressure was normal directly after surgery in all patients but 4, in whom blood pressure recovered to normal within a few weeks. CONCLUSIONS: This retrospective study shows that hypertension in WT patients is associated with elevated plasma renin levels, indicating that ACE inhibitors may be a good therapeutic option in at least a subset of WT patients with hypertension before nephrectomy.
