With angina pectoris and vasospastic angina pectoris - 5-10 mg / day, once. In order to prevent angina attacks - 10 mg / day.
Amlodipine is prescribed with caution in patients with impaired liver function as a hypotensive agent, at an initial dose of 2.5 mg (1/2 tablet of 5 mg), and 5 mg as an antianginal drug.
In elderly patients, T1 / 2 of amlodipine may increase and CC may decrease. Dose changes are not required, but closer monitoring of patients is necessary.
Dose changes are not required with simultaneous administration with thiazide diuretics, beta-blockers and ACE inhibitors.
No dose changes are required in patients with renal failure.
