Hypertension:
Indications for: LOTREL
Hypertension (not for initial therapy).
Adult Dosage:
For patients not adequately controlled with amlodipine or benazepril monotherapy or in those who show inability to achieve BP control with amlodipine without developing edema: initially 2.5mg/10mg once daily; may titrate up to 10mg/40mg once daily if BP remains uncontrolled. Replacement therapy: may be substituted for titrated components. CrCl ≤30mL/min: not recommended. Hepatic impairment, elderly: consider lower doses.
Children Dosage:
Not established.
LOTREL Contraindications:
History of ACEI-associated or other angioedema. Concomitant aliskiren in patients with diabetes. Concomitant neprilysin inhibitor (eg, sacubitril); do not administer within 36hrs of switching to or from sacubitril/valsartan.
Boxed Warning:
Fetal toxicity.
LOTREL Warnings/Precautions:
Fetal toxicity may develop; discontinue if pregnancy is detected. Correct salt/volume depletion prior to initiation. Renal or hepatic impairment. Dialysis (esp. high-flux membrane). Renal artery stenosis. CHF. Severe obstructive coronary artery disease. Severe aortic or mitral stenosis. Obstructive hypertrophic cardiomyopathy. Diabetes. Surgery. Discontinue and treat if angioedema, laryngeal edema, jaundice or marked elevation of liver enzymes develop. Monitor BP, electrolytes and renal function. Black patients may have higher rate of angioedema than non-black patients. Elderly. Neonates. Pregnancy: monitor. Nursing mothers.
LOTREL Classification:
Calcium channel blocker (CCB) (dihydropyridine) + ACE inhibitor.
LOTREL Interactions:
See Contraindications. Increased risk of angioedema with concomitant neprilysin inhibitor or mTOR inhibitor (eg, temsirolimus, sirolimus, everolimus). Dual inhibition of the renin-angiotensin system with ARBs, ACEIs, or aliskiren may increase risk of hypotension, hyperkalemia, renal function changes; monitor closely, in general, avoid combined use of RAS inhibitors. Avoid aliskiren in renal impairment (CrCl <60mL/min). Hyperkalemia with K+supplements, K+ -sparing diuretics, or salt substitutes. May increase lithium levels; monitor. Potentiates simvastatin (max 20mg daily). Potentiated by diuretics, CYP3A4 inhibitors. Nitritoid reactions with concomitant injectable gold (sodium aurothiomalate); rare. May be antagonized by, and renal toxicity potentiated by, NSAIDs, including selective COX-2 inhibitors (monitor renal function periodically in elderly and/or volume depleted). Hypoglycemia with insulin and oral antidiabetics; rare.
Adverse Reactions:
Cough, edema, fatigue, dizziness, GI upset, angioedema, hypotension, hyperkalemia, palpitations, flushing, anaphylactoid reactions; rare: hepatic failure.
Drug Elimination:
Benazepril: renal (primarily), biliary. Amlodipine: renal.
