Clinical Prescribing Information
Medical monograph and safety information for healthcare professionals & patients.Indications & Clinical Uses
Amdocal Pro tablet is indicated for the treatment of hypertension as substitution therapy in patients adequately controlled with the individual products given concurrently at the same dose level as in the combination, but as separate tablets.
Dosage & Administration
One tablet once daily in patients whose blood pressure is adequately controlled with separately administered monocomponent products of the same doses as the recommended fixed-dose combination.
Contraindications
Acute heart failure or during episodes of heart failure decompensation, obstruction of the outflow tract of the left ventricle (e.g. high grade aortic stenosis), cardiogenic shock, second or third degree AV block, sick sinus syndrome, sinoatrial block, symptomatic bradycardia or hypotension, severe bronchial asthma, severe forms of peripheral arterial occlusive disease or severe forms of Raynaud’s syndrome, untreated phaeochromocytoma metabolic acidosis, hypersensitivity to bisoprolol, amlodipine, dihydropyridine derivates or to any of the excipients.

Warnings & Precautions
Patients with heart failure should be treated with caution. An increased risk of a further deterioration of the ventricular pump function cannot be excluded. Since the abrupt withdrawal of bisoprolol may lead to a transitory worsening of the clinical condition, especially in patients with ischemic heart disease, the treatment must not be stopped abruptly. Caution is advised in patients with impaired hepatic function. Beta-blockers should be avoided in patients with obstructive airways diseases unless there are compelling clinical reasons for their use. Due to the bisoprolol component treatment must be used with caution in: bronchospasm (bronchial asthma, chronic obstructive airways disease; concomitant bronchodilating therapy may be recommended); diabetes mellitus showing large fluctuations in blood glucose values, symptoms of hypoglycemia can be masked; strict fasting; ongoing desensitization therapy; first degree AV block; Prinzmetal’s angina; peripheral arterial occlusive disease. Patients with psoriasis or with a history of psoriasis should only be given beta-blockers (e.g. bisoprolol) after a careful balancing of benefits and risks. Symptoms of thyrotoxicosis may be masked. In patients undergoing general anesthesia, the anesthetist must be aware of beta-blockade. If it is thought necessary to withdraw beta blocker therapy before surgery, this should be done gradually and completed about 48 hours before anesthesia.
Pharmacology & Mechanism of Action
Amlodipine is a dihydropyridine calcium antagonist that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. The contractile processes of cardiac muscle and vascular smooth muscle are dependent upon the movement of extracellular calcium ions into these cells through specific ion channels. Amlodipine inhibits calcium ion influx across cell membranes selectively, with a greater effect on vascular smooth muscle cells than on cardiac muscle cells. Amlodipine acts directly on vessels to cause a reduction in peripheral vascular resistance and reduction in blood pressure.
Bisoprolol Fumarate is a synthetic, beta1-selective (cardioselective) adrenoceptor blocking agent, lacking intrinsic sympathomimetic and relevant membrane stabilizing activity. It only shows low affinity to the beta2 receptor of the smooth muscles of bronchi and vessels as well as to the beta2-receptors concerned with metabolic regulation. Therefore, bisoprolol is generally not to be expected to influence airway resistance and beta2-mediated metabolic effects. Its beta1-selectivity extends beyond the therapeutic dose range.
