Since first described in the 1950s, prodrugs Prodrugs are substances administered in an inactive form that is then metabolized in the body in vivo into the active compound.
Enalapril increased renal blood flow, glomerular filtration rate and sodium excretion. (ABSTRACT TRUNCATED AT 250 WORDS) 2000 Jul;130(6):1339-47. doi: 10.1038/sj.bjp.0703422.Cerasola G, Cottone S, D'Ignoto G, Grasso L, Carone MB, Carapelle E, Contorno A.Salvetti A, Pedrinelli R, Arzilli F, Abdel-Haq B, Magagna A, Lucarini A, Graziadei L, Nuccorini A, Taddei S.Front Neurosci.
In sodium-deficient rats, the enalapril-sensitive component of the blood pressure was greatly reduced after salt loading, and nephrectomy blocked the antihypertensive response to enalapril in SHR. Figure 11. Published by Elsevier Inc. All rights reserved.ScienceDirect ® is a registered trademark of Elsevier B.V. Previous work in rats has shown that the prodrug ACE inhibitor, enalapril (MK-421), lowered blood pressure most effectively when PRA was elevated [sodium deficiency, two-kidney, one figure 8 hypertension, diuretic-treated spontaneously hypertensive rats (SHR)]. Start studying NAPLEX Brand-Generic Drugs. reduced preload, afterload and improved LV performance without changing the heart rate.
Enlaprilic acid did not alter the enhanced hindquarter vasoconstrictor responses to sympathetic nerve stimulation. Get this from a library! An interaction of enalaprilic acid with the sympathetic nervous system was evaluated in dogs in which adrenergic activity was enhanced as a result of diuretic-induced renin release. It is an acetoxyethyl ester prodrug of cefuroxime which is effective orally.

In rat, CS total values of tested prodrugs were over 0.7 except for enalapril. The activity depends on in vivo hydrolysis and release of cefuroxime tablets.. The mechanism of action of angiotensin converting enzyme (ACE) inhibitors to lower blood pressure remains unclear, but the weight of available data favour peripheral blockade of the formation of angiotensin II (AII). In the present studies in adult SHR, a central site of action was ruled out since the parent inhibitor, enalaprilic acid (MK-422), injected into the brain ventricles did not acutely reduce blood pressure. This site needs JavaScript to work properly. 1986 Mar;31(3):198-248. doi: 10.2165/00003495-198631030-00002.Sánchez RA, Marcó E, Gilbert HB, Raffaele P, Brito M, Giménez M, Moledo LI.Drugs. From earlier studies in SHR, the time course for blockade of angiotensin I (AI) pressor responses and the blood pressure reduction did not correspond, suggesting a tissue site of action. Enalaprilic acid at 100 micrograms/kg i.v. Further, it has been reported that the small intestines of both rat and human contain mainly CES2. In conclusion, enalapril the prodrug, and enalaprilic acid the active inhibitor, are potentially useful in the treatment of hypertension and LV failure.

Poor oral bioavailability of the active species due to poor GIT permeation was the need addressed by these prodrugs. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The conventional pharmacokinetic profile of the angiotensin converting enzyme (ACE) inhibitor, enalapril, is a lipid-soluble and relatively inactive prodrug with good oral absorption (60 to 70%), a rapid peak plasma concentration (1 hour) and rapid clearance (undetectable by 4 hours) by de-esterification in the liver to a primary active diacid metabolite, enalaprilat.
