制造商: Manufacturer:Novartis Pharmaceuticals Corp Pharmacological Class:Antihypertensive (renin inhibitor + dihydropyridine [DHP] calcium channel blocker [CCB]). Active Ingredient(s):Aliskiren 150mg, amlodipine 5mg; tablets. Also:TEKAMLO 150mg/10mg Indication(s):Hypertension. Pharmacology:Tekamlo combines aliskiren, a direct renin inhibitor, with the calcium channel blocker, amlodipine, for the treatment of hypertension. Patients whose blood pressure (BP) is inadequately controlled by monotherapy with aliskiren or amlodipine (or another DHP CCB) can be switched to this combination product. Alternatively, this product can be substituted for the individually-titrated components, or it may be used as initial therapy. The effects of this combined product on BP are the result of complementary mechanisms that regulate BP, vasoconstriction, and sodium excretion. Aliskiren reduces plasma renin activity and inhibits the conversion of angiotensinogen to angiotensin I, resulting in a decrease in BP. Amlodipine inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. It is also a peripheral arterial vasodilator that reduces peripheral vascular resistance and BP. Clinical Trials:Aliskiren and amlodipine were studied alone and in combination in an 8-week, randomized, multifactorial study comparing various dose combinations with placebo. Over five thousand patients with mild to moderate hypertension (DBP 90–109mmHg) were enrolled. Treatment with Tekamlo resulted in an overall significantly greater reduction in diastolic and systolic BP compared to treatment with the respective monotherapy drugs. In other studies, patients with moderate to severe hypertension (SBP 160–200 mmHg) were given initial therapy with either aliskiren + amlodipine or amlodipine monotherapy. In one study involving 484 patients, the treatment difference between combination therapy and amlodipine alone at 8 weeks was 7.1/3.8mmHg. In a study involving 443 Black patients, the treatment difference was 5.2/3.8mmHg. Legal Classification:Rx Adults:Give once daily, consistently with regard to meals. Initial therapy: One 150mg/5mg tablet daily. Add-on: switch when BP is not controlled with aliskiren or any DHP CCB alone. Replacement therapy: switch from previously-titrated components. Titrate at 2 to 4-week intervals (slow titration in hepatic impairment or heart failure); max one 300mg/10mg tablet daily. Children:Not recommended. Warnings/Precautions:Pregnancy (Cat.D; avoid); discontinue as soon as pregnancy detected. Correct salt/volume depletion before starting or start under close supervision. Severe obstructive coronary disease; increased risk of angina or MI with CCB upon dose initiation or change. Moderate to severe renal dysfunction; consider monitoring electrolytes. History of dialysis. Nephrotic syndrome. Renovascular hypertension. Renal artery stenosis. Severe hepatic impairment. Heart failure. Monitor for hyperkalemia (esp. in diabetics on ACE inhibitors). Nursing mothers: not recommended. Interaction(s):Concomitant cyclosporine: not recommended. Caution with ACE inhibitors, K+ supplements, K+ sparing diuretics, K+ containing salt substitutes. May antagonize furosemide. Potentiated by atorvastatin, ketoconazole. Antagonized by irbesartan. Adverse Reaction(s):Peripheral edema; diarrhea, cough, rash, hyperuricemia; rare: angioedema (discontinue if occurs, do not restart), hypotension.
