Aliskiren and Amlodipine

Generic name: aliskiren/amlodipine systemic

Brand names: Tekamlo

Boxed Warning

Fetal toxicity:

When pregnancy is detected, discontinue aliskiren/amlodipine as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus.

Pharmacology

Mechanism of Action

Aliskiren: Decreases plasma renin activity and inhibits conversion of angiotensinogen to angiotensin I.

Amlodipine: Inhibits calcium ion from entering the "slow channels" or select voltage-sensitive areas of vascular smooth muscle and myocardium during depolarization, producing a relaxation of coronary vascular smooth muscle and coronary vasodilation; increases myocardial oxygen delivery in patients with vasospastic angina. Amlodipine directly acts on vascular smooth muscle to produce peripheral arterial vasodilation reducing peripheral vascular resistance and blood pressure.

Use: Labeled Indications

Hypertension: Management of hypertension (monotherapy or in combination with other antihypertensives).

Contraindications

Hypersensitivity to aliskiren, amlodipine, or any component of the formulation; concomitant use with an ACE inhibitor or ARB in patients with diabetes.

Dosage and Administration

Dosing: Adult

Hypertension: Oral: Note: Dosage must be individualized. Prior to initiation, correct hypovolemia and/or closely monitor volume status in patients on concurrent diuretics during treatment initiation.

Initial therapy or add on therapy: Initial: Aliskiren 150 mg/amlodipine 5 mg once daily; may titrate after 2 to 4 weeks of therapy. Maximum: Aliskiren 300 mg/amlodipine 10 mg per day.

Replacement therapy: Substitute for the individually titrated components. Maximum: Aliskiren 300 mg/amlodipine 10 mg per day.

Dosing: Geriatric

Refer to adult dosing. Consider initiating with lowest dose.

Administration

Administer at the same time daily with or without a meal, but consistent administration with regards to meals is recommended.

Dietary Considerations

May be taken with or without food, however, a high-fat meal reduces absorption. Consistent administration with regards to meals is recommended.

Storage

Store at 25°C (77°F); excursions permitted to 15°C to 30°C (59°F to 86°F). Protect from heat and moisture. Dispense in original container.

Adverse Reactions

Frequencies reported with combination product. See individual monographs for additional adverse effects reported with each agent.

Warnings/Precautions

Concerns related to adverse effects:

  • Angina/MI: Increased angina and/or MI have occurred with initiation or dosage titration of dihydropyridine calcium channel blockers, including amlodipine. Reflex tachycardia may occur resulting in angina and/or MI in patients with obstructive coronary disease, especially in the absence of concurrent beta-blockade.
  • Hyperkalemia: May occur; risk increased in patients with renal impairment or diabetes, or concomitant use with ACE inhibitors, ARBs, NSAIDs, potassium-sparing diuretics, potassium supplements, and/or potassium-containing salts.
  • Hypersensitivity: Anaphylaxis and angioedema have been reported. Since the effect of aliskiren on bradykinin levels is unknown, the risk of kinin-mediated etiologies of angioedema occurring is also unknown. Use with caution in any patient with a history of angioedema (of any etiology) as angioedema has been observed with aliskiren use. Discontinue immediately following the occurrence of anaphylaxis or angioedema; do not readminister. Prolonged frequent monitoring may be required especially if tongue, glottis, or larynx are involved as they are associated with airway obstruction. Patients with a history of airway surgery may have a higher risk of airway obstruction. Aggressive, early, and appropriate management is critical.
  • Hypotension: During the initiation of therapy, symptomatic hypotension may occur, particularly in volume or salt-depleted patients or with concomitant use of other agents acting on the renin-angiotensin-aldosterone system. Prior to initiation, correct hypovolemia or salt depletion, or closely monitor during treatment initiation. If hypotension does occur, this is not a contraindication for further use; once blood pressure has been stabilized, aliskiren usually can be continued without difficulty.
  • Renal effects: Changes in renal function, including acute renal failure, may occur with aliskiren; risk is increased in patients with renal artery stenosis, severe heart failure, post-myocardial infarction, volume depletion, or patients receiving ARB, ACEI, or NSAIDs. Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in renal function.
  • Peripheral edema: The most common side effect of amlodipine is peripheral edema; occurs within 2 to 3 weeks of starting therapy.

Disease-related concerns:

  • Aortic stenosis: Use amlodipine with extreme caution in patients with severe aortic stenosis; may reduce coronary perfusion resulting in ischemia.
  • Diabetes: Use in patients with diabetes has demonstrated an increased incidence of renal impairment, hypotension, and hyperkalemia; use is contraindicated in patients with diabetes who are taking an ACE inhibitor or ARB.
  • Hepatic impairment: Use with caution in patients with hepatic impairment; consider using lower doses.
  • Hypertrophic cardiomyopathy (HCM) with outflow tract obstruction: Use amlodipine with caution in patients with HCM and outflow tract obstruction since reduction in afterload may worsen symptoms associated with this condition.
  • Renal impairment: Use with caution in patients with renal impairment; risk of developing acute renal failure and hyperkalemia is increased. Avoid concomitant use with an ACE inhibitor or ARB in patients with CrCl <60 mL/minute.

Concurrent drug therapy:

  • Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

  • Elderly: Exposure to amlodipine is increased in the elderly; consider using lowest initial dose.
  • Pregnancy: [US Boxed Warning]: Drugs that act on the renin-angiotensin system can cause injury and death to the developing fetus. Discontinue as soon as possible once pregnancy is detected.

Pregnancy Considerations

[US Boxed Warning]: Drugs that act on the renin-angiotensin system can cause injury and death to the developing fetus. Discontinue as soon as possible once pregnancy is detected. See individual agents for additional information.

Patient Education

  • Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
  • Patient may experience cough, loss of strength and energy, diarrhea, or flu-like symptoms. Have patient report immediately to prescriber signs of liver problems (dark urine, fatigue, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or yellow skin), signs of kidney problems (unable to pass urine, blood in the urine, change in amount of urine passed, or weight gain), signs of high potassium (abnormal heartbeat, confusion, dizziness, passing out, weakness, shortness of breath, numbness or tingling feeling), severe dizziness, passing out, chest pain, shortness of breath, excessive weight gain, swelling of arm or leg, difficulty swallowing, stiff muscles, tremors, abnormal movements, or signs of Stevens-Johnson syndrome/toxic epidermal necrolysis (red, swollen, blistered, or peeling skin [with or without fever]; red or irritated eyes; or sores in mouth, throat, nose, or eyes) (HCAHPS).
  • Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
