The product should be used with caution in patients with reduced left ventricular function. Patients with bradycardia (risk of exacerbation), first degree AV block or prolonged PR interval should be observed closely. Cases of acute renal failure secondary to decreased renal perfusion have been reported in patients with existing cardiac disease especially reduced left ventricular function, severe bradycardia or severe hypotension.
Careful monitoring of renal function is advised. Diltiazem is considered unsafe in patients with acute porphyria. Prior to general anaesthesia, the anaesthetist must be informed of ongoing diltiazem treatment. Depression of cardiac contractility, conductivity and automaticity, as well as the vascular dilatation associated with anaesthetics may be potentiated by calcium channel blockers.
Increase of plasma concentrations of diltiazem may be observed in the elderly and in patients with renal or hepatic insufficiency. The contraindications and precautions should be carefully observed and close monitoring, particularly of heart rate, should be carried out at the beginning of treatment.
Calcium channel blocking agents, such as diltiazem, may be associated with mood changes, including depression. Like other calcium channel antagonists, diltiazem has an inhibitory effect on intestinal motility. Therefore it should be used with caution in patients at risk of developing an intestinal obstruction.
Tablet residues from slow release formulations of the product may pass into the patient’s stools; however, this finding has no clinical relevance. Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.
This medicine contains less than 1mmol sodium (23mg) per capsule, that is to say essentially ‘sodium-free’.
Hypersensitivity to diltiazem or to any of the excipients. Pregnancy and in women of child bearing capacity. Patients with severe bradycardia (less than 40 bpm), second or third degree heart block, sick sinus syndrome, decompensated cardiac failure, patients with left ventricular failure with pulmonary congestion.
