e renin-angiotensin-aldosterone system.
Renal impairment and kidney transplantation:
When Sevikar is used in patients with impaired renal function, periodic monitoring of serum potassium and creatinine levels is recommended. Use of Sevikar is not recommended in patients with severe renal impairment (creatinine clearance < 20 mL/min) (see sections 4.2, 5.2). There is no experience of the administration of Sevikar in patients with a recent kidney transplant or in patients with end-stage renal impairment (i.e. creatinine clearance < 12 mL/min).
Dual blockade of the renin-angiotensin-aldosterone system (RAAS):
There is evidence that the concomitant use of ACE-inhibitors, angiotensin II receptor blockers or aliskiren increases the risk of hypotension, hyperkalaemia and decreased renal function (including acute renal failure). Dual blockade of RAAS through the combined use of ACE-inhibitors, angiotensin II receptor blockers or aliskiren is therefore not recommended (see sections 4.5 and 5.1).
If dual blockade therapy is considered absolutely necessary, this should only occur under specialist supervision and subject to frequent close monitoring of renal function, electrolytes and blood pressure.
ACE-inhibitors and angiotensin II receptor blockers should not be used concomitantly in patients with diabetic nephropathy.
Hepatic impairment:
Exposure to amlodipine and olmesartan medoxomil is increased in patients with hepatic impairment (see section 5.2). Care should be taken when Sevikar is administered in patients with mild to moderate hepatic impairment. In moderately impaired patients, the dose of olmesartan medoxomil should not exceed 20 mg (see section 4.2). In patients with impaired hepatic function, amlodipine should be initiated at the lower end of the dosing range and caution should be used, both on initial treatment and when increasing the dose. Use of Sevikar in patients with severe hepatic impairment is contraindicated (see section 4.3).
Hyperkalaemia:
As with other angiotensin II antagonists and ACE inhibitors, hyperkalaemia may occur during treatment, especially in the presence of renal impairment and/or heart failure (see section 4.5). Close monitoring of serum potassium levels in at-risk patients is recommended.
Concomitant use with potassium supplements, potassium-sparing diuretics, salt substitutes containing potassium, or other medicinal products that may increase potassium levels (heparin, etc.) should be undertaken with caution and with frequent monitoring of potassium levels.
Lithium:
As with other angiotensin II receptor antagonists, the concomitant use of Sevikar and lithium is not recommended (see section 4.5).
Aortic or mitral valve stenosis; obstructive hypertrophic cardiomyopathy:
Due to the amlodipine component of Sevikar, as with all other vasodilators, special caution is indicated in patients suffering from aortic or mitral valve stenosis, or obstructive hypertrophic cardiomyopathy.
Primary aldosteronism:
Patients with primary aldosteronism generally will not respond to antihypertensive medicinal products acting through inhibition of the renin-angiotensin system. Therefore, the use of Sevikar is not recommended in such patients.
Heart failure:
As a consequence of the inhibition of the renin-angiotensin-aldosterone system, changes in renal function may be anticipated in susceptible individuals. In patients with severe heart failure whose renal func |
