- Capsules should not be sucked or chewed.

- The use of diltiazem hydrochloride in diabetic patients may require adjustment of their control.

- Plasma diltiazem concentrations can be increased in the elderly and 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.

- Prior to general anaesthesia, the anaesthetist must be informed of ongoing diltiazem treatment. The 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.

- The product should be used with caution in patients with hepatic dysfunction. Abnormalities of liver function may occur during therapy. Very occasional reports of abnormal liver function have been received; these reactions have been reversible upon discontinuation of therapy.

- First degree AV block or prolonged PR interval. Diltiazem prolongs AV node refractory periods without significantly prolonging sinus node recovery time, except in patients with sick sinus syndrome. This effect may rarely result in abnormally slow heart rates (particularly in patients with sick sinus syndrome) or second or third degree AV block.

- Close observation is necessary in patients with reduced left ventricular function and bradycardia (risk of exacerbation) or with a 1st degree AV block detected on the electrocardiogram (risk of exacerbation and rarely of complete block) or prolonged PR interval.

- Diltiazem is not recommended for use in patients with acute porphyria unless other safer alternatives are not available.

- There have been reports of calcium-channel blockers exacerbating muscle weakness in patients with myasthenia gravis. Diltiazem should be used with caution in such patients.

- 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 to develop 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.

- Diltiazem does not affect the glucose or endogenous insulin responses to hypoglycaemia.

- Owing to the presence of sucrose, patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.

As with any drug given over prolonged periods, laboratory parameters should be monitored at regular intervals.

Rare instances of hyperglycaemia have been reported in association with diltiazem hydrochloride. The use of diltiazem in diabetic patients may require adjustment of their control.

Precaution should be taken in patients with reduced left ventricular function. Patients should be observed closely if they have bradycardia (risk of exacerbation), first degree AV block detected on the electrocardiogram (risk of exacerbation and rarely, of complete block) or prolonged PR interval.

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.

The clinical effects of acute overdose can involve pronounced hypotension possibly leading to collapse, sinus bradycardia with or without isorhythmic dissociation, and atrioventricular conduction disturbances.

Experience of overdosage in man is limited but cases of spontaneous recovery have been reported. However, it is recommended that patients with suspected overdose should be placed under observation in a coronary care unit with facilities available for treatment of any possible hypotension and conduction disturbances that may occur. Conduction disturbances may be managed by temporary cardiac pacing. Most patients suffering from overdosage of diltiazem become hypotensive within 8 hours of ingestion. With bradycardia and first to third degree atrioventricular block also developing cardiac arrest may ensue. Hyperglycaemia is also a recognised complication. The elimination half-life of diltiazem after overdosage is estimated to be about 5.5 - 10.2 hours. If a patient presents early after overdose, gastric lavage should be performed under hospital supervision and activated charcoal administered to reduce diltiazem absorption.

Hypotension should be corrected with plasma expanders, intravenous calcium gluconate and inotropic agents (dopamine, dobutamine or isoprenaline). Symptomatic bradycardia and high grade AV block may respond to atropine, isoprenaline or occasionally cardiac pacing which may be useful if cardiac standstill occurs.

Proposed corrective treatments: atropine, vasopressors, inotropic agents, glucagon and calcium gluconate infusion.

Symptoms

The clinical effects of acute overdose can involve pronounced hypotension possibly leading to collapse, sinus bradycardia with or without isorhythmic dissociation, and atrioventricular conduction disturbances. It is recommended that patients with suspected overdose should be placed under observation in a coronary care unit.

Most patients suffering from overdosage of diltiazem become hypotensive within 8 hours of ingestion. With bradycardia and first to third degree atrioventricular block also developing, cardiac arrest may ensue. Hyperglycaemia is also a recognised complication. The elimination half-life of diltiazem after overdosage is estimated to be about 5.5-10.2 hours.

The following may be linked to renal impairment in patients; polyuri, pollakiuria, nocturia, acute kidney injury, acute interstitiel nephritis.

Management

Treatment, in a hospital setting, will include gastric lavage with administration of activated charcoal to reduce diltiazem absorption and/or osmotic diuresis. Conduction disturbances may be managed by temporary cardiac pacing. Proposed corrective treatments: Hypotension should be corrected with plasma expanders, vasopressors, glucagon, calcium gluconate infusion and inotropic agents (e.g. dopamine, dobutamine or isoprenaline). Symptomatic bradycardia and high grade AV block may respond to atropine, isoprenaline or occasionally cardiac pacing which may be useful if cardiac standstill occurs.

Lacerol Retard SR capsules are prolonged release capsules and effects may be slow in onset and prolonged, therefore, monitoring should be carried out for longer periods than following overdose with immediate-release dosage forms.

Pharmacotherapeutic group: Calcium channel Blocker, ATC code: C08D B01

Mechanism of action

Diltiazem is a calcium channel antagonist which restricts the entry of calcium ions into the cell through the slow voltage dependent channels and reduces the liberation of calcium from the endoplasmic reticulum. This results in a reduced amount of available intracellular calcium. The haemodynamic actions of diltiazem are:

Peripheral and coronary vasodilatation.

Decrease in myocardial oxygen consumption.

Reduction of blood pressure particularly in hypertension.

Increase in renal blood flow and urinary sodium excretion

Diltiazem has pharmacologic actions similar to those of other calcium channel blocking agents such as nifedipine or verapamil. The principal physiologic action of diltiazem is to inhibit the transmembrane influx of extracellular calcium ions across the membranes of myocardial cells and vascular smooth muscle cells.

Calcium plays important roles in the excitation-contraction coupling processes of the heart and vascular smooth muscle cells and in the electrical discharge of the specialised conduction cells of the heart. The membranes of these cells contain numerous channels that carry a slow inward current and that are selective for calcium.

By inhibiting calcium influx, diltiazem inhibits the contractile processes of cardiac and vascular smooth muscle, thereby dilating the main coronary and systemic arteries. Dilation of systemic arteries by diltiazem results in a decrease in total peripheral resistance, a decrease in systemic blood pressure and a decrease in the afterload of the heart. The reduction in afterload, seen at rest and with exercise, and its resultant decrease in myocardial oxygen consumption are thought to be responsible for the beneficial effects of diltiazem in patients with chronic stable angina pectoris. In patients with prinzmetal variant angina, inhibition of spontaneous and ergonovine-induced coronary artery spasm by diltiazem results in increased myocardial oxygen delivery.

Pharmacotherapeutic group: Selective calcium channel blockers with direct cardiac effects:

ATC code: C08DB01

Diltiazem hydrochloride is a calcium-channel blocking agent. It is a peripheral and coronary vasodilator with some negative inotropic activity. Diltiazem inhibits cardiac conduction particularly at the sino-atrial and atrioventricular nodes. It is used in the management of classical and vasospastic angina pectoris and it is also used in the treatment of essential hypertension.

a) General Characteristics

Absorption

When taken orally diltiazem is almost completely absorbed. Despite this, the absolute bioavailability is 40% due to extensive first pass metabolism. Bioavailability is not affected by age. Diltiazem is 78-87% bound to plasma proteins but only 35-40% to albumin. The peak plasma concentration is reached in about three hours after single dose of diltiazem 90 mg CR tablets. The Cmax value was 50-65 ng/ml. Capsules seem to have a similar bioavailability to tablets (30-40%), with peak concentrations for the prolonged release product after 8-11 hours compared with 1-2 hours after the conventional release product. The relatively low bioavailability is due to first pass metabolism in the liver to an active metabolite.

Distribution

Diltiazem hydrochloride is lipophilic and has a high volume of distribution. Typical study results are in the range of 3-8 litres/kg. Protein binding is about 80% and is not concentration-dependent at levels likely to be found clinically. Protein binding does not appear to be influenced by phenylbutazone, warfarin, propranolol, salicylic acid or digoxin.

Metabolism

Diltiazem hydrochloride is extensively metabolised in the liver by deacetylation and N-demethylation followed by O-demethylation or deacetylation. N-monodesmethyl diltiazem is the predominant metabolite followed quantitatively by the desacetyl metabolite, which has some hypotensive potency. The efficacy of the metabolites, desacetyl diltiazem and N-monodesmethyl diltiazem is 25-50% and about 20% respectively of that of diltiazem. In liver function disorders delayed metabolism in the liver is likely. These metabolites are converted to conjugates, generally the glucuronide or the sulphate.

Elimination

Diltiazem is excreted in the form of its metabolites (about 35%) and in the non-metabolised form (about 2-4%) via the kidneys while about 60% is excreted via the faeces Diltiazem is mainly excreted as metabolites in the urine and faeces and only 1-3% of the dose is excreted as the parent compound in urine. The average elimination half life period for diltiazem is 6-8 hours but may vary between 2 and 11 hours. Although the elimination half life is not changed after repeated oral administration, diltiazem and also the desacetyl metabolite show a slight accumulation in the plasma.

b) Characteristics in Patients

Decreased first-pass metabolism in the elderly tends to result in increased plasma concentrations of calcium antagonists but no major changes have been found with diltiazem. Renal impairment did not cause significant changes in diltiazem pharmacokinetics. Plasma concentrations of diltiazem also tend to be higher in hepatic cirrhosis due to impaired oxidative metabolism.

Absorption

Diltiazem is rapidly and almost completely absorbed from the gastro-intestinal tract following oral administration, but undergoes extensive first-pass hepatic metabolism. The bioavailability has been reported to be about 40%, although there is considerable inter-individual variation in plasma concentrations.

Distribution

Diltiazem is about 80% bound to plasma proteins.

Biotransformation

It is extensively metabolised in the liver; one of the metabolites, desacetyl diltiazem has been reported to have 25 to 50% of the activity of the parent compound. The half-life is reported to be about 3 to 4 hours.

Elimination

Approximately 60% of the dose is excreted in the bile and 35 to 40% in the urine, and 2 to 4% as unchanged diltiazem.

The prolonged-release formulation is designed for twice daily dosage.
