Enalaprilat SteriMax (Enalaprilat)
Enalaprilat SteriMax (Enalaprilat) Uses, Dosage, Side Effects, Food Interaction and all others data.
Enalaprilat SteriMax (Enalaprilat) is the active metabolite of the orally available pro-drug, enalapril. Used in the treatment of hypertension, enalapril is an ACE inhibitor that prevents Angiotensin Converting Enzyme (ACE) from transforming angiotensin I into angiotensin II. As angiotensin II is responsible for vasoconstriction and sodium reabsorption in the proximal tubule of the kidney, down-regulation of this protein results in reduced blood pressure and blood fluid volume. Enalaprilat SteriMax (Enalaprilat) was originally created to overcome the limitations of the first ACE inhibitor, captopril, which had numerous side effects and left a metallic taste in the mouth. Removal of the problematic thiol group from captopril resulted in enalaprilat, which was then modified further with an ester to create the orally available pro-drug enalapril.
Enalaprilat SteriMax (Enalaprilat) is poorly orally available and is therefore only available as an intravenous injection for the treatment of hypertension when oral therapy is not possible.
Enalaprilat SteriMax (Enalaprilat) injection results in the reduction of both supine and standing systolic and diastolic blood pressure, usually with no orthostatic component. Symptomatic postural hypotension is therefore infrequent, although it might be anticipated in volume-depleted patients. The onset of action usually occurs within fifteen minutes of administration with the maximum effect occurring within one to four hours. The abrupt withdrawal of enalaprilat has not been associated with a rapid increase in blood pressure.The duration of hemodynamic effects appears to be dose-related. However, for the recommended dose, the duration of action in most patients is approximately six hours.Following administration of enalapril, there is an increase in renal blood flow; glomerular filtration rate is usually unchanged. The effects appear to be similar in patients with renovascular hypertension.

Uses
Enalaprilat SteriMax (Enalaprilat) is an antihypertensive agent used for the management of hypertension when oral therapy is not practical.
Enalaprilat SteriMax (Enalaprilat) injection is indicated for the treatment of hypertension when oral therapy is not practical.
Enalaprilat SteriMax (Enalaprilat) is also used to associated treatment for these conditions: Diabetic Nephropathy, Heart Failure, High Blood Pressure (Hypertension), Left Ventricular Dysfunction
How Enalaprilat SteriMax (Enalaprilat) works
Enalaprilat SteriMax (Enalaprilat) is the active metabolite of the orally available pro-drug, enalapril. Used in the treatment of hypertension, enalapril is an ACE inhibitor that prevents Angiotensin Converting Enzyme (ACE) from transforming angiotensin I into angiotensin II. As angiotensin II is responsible for vasoconstriction and sodium reabsorption in the proximal tubule of the kidney, down-regulation of this protein results in reduced blood pressure and blood fluid volume
Toxicity
Adverse experiences occurring in 0.5 to 1.0 percent of patients in controlled clinical trials included: myocardial infarction, fatigue, dizziness, fever, rash and constipation. Angioedema has also been reported in patients receiving enalaprilat, with an incidence higher in black than in non-black patients. Angioedema associated with laryngeal edema may be fatal. If angioedema of the face, extremities, lips, tongue, glottis and/or larynx occurs, treatment with enalaprilat should be discontinued and appropriate therapy instituted immediately .
Rarer adverse effects that are less likely, but should be monitored for, include development of anaphylaxis, hypotension, agranulocytosis, hepatic failure, hyperkalemia, and persistent cough.
Furthermore, ACE inhibitors should be avoided during pregnancy as they can cause fetal and neonatal morbidity and death. When pregnancy is detected, ACE inhibitors should be discontinued as soon as possible. Use during the second and third trimesters of pregnancy has been associated with fetal and neonatal injury, including hypotension, neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, and death.
Food Interaction
No interactions found.[Moderate] GENERALLY AVOID: Moderate-to-high dietary intake of potassium can cause hyperkalemia in some patients who are using angiotensin converting enzyme (ACE) inhibitors.
In some cases, affected patients were using a potassium-rich salt substitute.
ACE inhibitors can promote hyperkalemia through inhibition of the renin-aldosterone-angiotensin (RAA) system.
MANAGEMENT: It is recommended that patients who are taking ACE inhibitors be advised to avoid moderately high or high potassium dietary intake.
Particular attention should be paid to the potassium content of salt substitutes.
Enalaprilat SteriMax (Enalaprilat) Drug Interaction
Major: spironolactone, sulfamethoxazole / trimethoprim, sulfamethoxazole / trimethoprimModerate: aspirin, aspirin, lorazepam, ibuprofen, enoxaparin, quetiapine, alprazolamUnknown: lactobacillus acidophilus, ursodiol, albumin human, cefazolin, testosterone, donepezil, moxifloxacin, botulism immune globulin, Allergy , pantoprazole
Enalaprilat SteriMax (Enalaprilat) Disease Interaction
Major: angioedema, bone marrow suppression, CHF, hemodialysis, hyperkalemia, hypotensionModerate: liver disease, renal dysfunction
Elimination Route
Enalaprilat SteriMax (Enalaprilat) is poorly absorbed following oral administration, and is therefore only available as an intravenous injection.
Half Life
11 hr
Clearance
The disposition of enalaprilat in patients with renal insufficiency is similar to that in patients with normal renal function until the glomerular filtration rate is 30 mL/min or less. Renal clearance was 158 ± 47 ml/min.
Elimination Route
Excretion of enalaprilat is primarily renal with more than 90 percent of an administered dose recovered in the urine as unchanged drug within 24 hours.
