4 CLINICAL PARTICULARS
4.1 Therapeutic indications
Molap is indicated for the treatment of essential hypertension either alone or in combination with other antihypertensive agents, including B-adrenoceptor antagonists, diuretics, and ACE-inhibitors.
4.2 Posology and method of administration
Posology
The treatment of hypertension should be adapted to the severity of the condition, and according to the individual response.
The recommended initial dose is 2 mg once daily. The dose may be increased to 4 mg (and then, if necessary, to 6 mg) after adequate time has been allowed for the full pharmacological effect to occur. In practice, this should not be less than 3 to 4 weeks. Daily doses above 6 mg have not been shown to be significantly more effective.
Molap should be taken at the same time each day, preferably in the morning.
The treatment with Molap may be continued indefinitely.
Patients with hepatic impairment:
Lacidipine is metabolised primarily by the liver and therefore in patients with hepatic impairment, the bioavailability of Molap may be increased and the hypotensive effect enhanced. These patients should be carefully monitored, and in severe cases, a dose reduction may be necessary.
Patients with renal impairment:
As Molap is not cleared by the kidneys, the dose does not require modification in patients with kidney disease.
Pediatric population:
Since no experience has been gained with lacidipine in children, the administration of Molap is not recommended in children and adolescents <18 years.
Elderly:
No dose adjustment is necessary in the elderly.
Method of administration
For oral administration
4.3 Contraindications
Molap is contraindicated in patients with known hypersensitivity to the active substance or to any of the excipients listed in section 6.1. Molap should only be used with great care in patients with a previous allergic reaction to another dihydropyridine because there is a theoretical risk of cross-reactivity.
In addition, dihydropyridines have been shown to reduce coronary arterial blood-flow in patients with aortic stenosis and in such patients Molap is contraindicated.
As with other calcium antagonists, lacidipine should be discontinued in patients who develop cardiogenic shock and unstable angina.
Lacidipine should not be used during or within one month of a myocardial infarction and in case of severe left ventricular failure.
4.4 Special warnings and precautions for use
In specialised studies lacidipine has been shown not to affect the spontaneous function of the SA node or to cause prolonged conduction within the AV node. However, the theoretical potential for a calcium antagonist to affect the activity of the SA and AV nodes should be noted, and therefore lacidipine should be used with caution in patients with pre-existing abnormalities in the activity of the SA and AV nodes.
As has been reported with other dihydropyridine calcium channel antagonists, lacidipine should be used with caution in patients with congenital or documented acquired QT prolongation. Lacidipine should also be used with caution in patients treated concomitantly with medications known to prolong the QT interval such as class I and III antiarrhythmics, tricyclic antidepressants, some antipsychotics, antibiotics (e.g. erythromycin) and some antihistamines (e.g. terfenadine).
As with other calcium antagonists, lacidipine should be used with caution in patients with poor cardiac reserve.
There is no evidence that lacidipine is useful for secondary prevention of myocardial infarction.
The efficacy and safety of lacidipine tablets in the treatment of malignant hypertension has not been established.
Lacidipine should be used with caution in patients with impaired liver function because antihypertensive effect may be increased.
There is no evidence that lacidipine impairs glucose tolerance or alters diabetic control.
This product contains Lactose Monohydrate. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.
4.5 Interaction with other medicinal products and other forms of interaction
Lacidipine is known to be metabolised by cytochrome CYP3A4 and, therefore, caution should be exercised when lacidipine is administered with drugs which inhibit the CYP 3A4 enzyme, such as ketoconazole, itraconazole, or with drugs which induce CYP 3A4, such as phenytoin, carbamazepin, phenobarbital and rifampicin and posology of lacidipine should be adjusted if needed.
Other antihypertensive agents
Co-administration of lacidipine with other agents recognised to have a hypotensive effect, including anti-hypertensive agents, (e.g. diuretics, beta-blockers or ACE-inhibitors), may have an additive hypotensive effect. However, no specific interaction problems have been identified in studies with common antihypertensive agents (e.g. beta-blockers and diuretics) or with digoxin, tolbutamide or warfarin.
The plasma level of lacidipine may be increased by simultaneous administration of cimetidine.
Alcohol
As with all antihypertensives (vasodilators) caution is recommended when alcohol is consumed since this may increase the effects.
Grapefruit juice
As with other dihydropyridines, lacidipine should not be taken with grapefruit juice as bioavailability may be altered.
Lacidipine is highly protein-bound (more than 95%) to albumin and alpha-1-glycoprotein.
In clinical studies in patients with a renal transplant treated with cyclosporin, lacidipine reversed the decrease in renal plasma flow and glomerular filtration rate induced by cyclosporin.
Concomitant use of lacidipine and corticoids or tetracosactide might decrease antihypertensive effect.
4.6 Fertility, pregnancy and lactation
Pregnancy:
There are no clinical data on the use of this drug in pregnant women.
Although some calcium channel blockers have been found to be teratogenic in animals, studies with lacidipine in animals have not shown malformations. At high doses, embryo-fetal lethality and toxicity were found in animals (see section 5.3). Lacidipine should only be used in pregnancy when the potential benefits for the mother outweigh the possibility of adverse effects in the fetus or neonate.
The possibility that lacidipine can cause relaxation of the uterine muscle at term should be considered (see section 5.3)
Breastfeeding:
Lacidipine and its metabolites are likely to be excreted into breast milk. Therefore the use of Molap during lactation should be avoided.
Lacidipine should only be used during lactation when the potential benefits for the mother outweigh the possibility of adverse effects in the foetus or neonate.
Fertility:
Some patients treated with calcium channel blockers have reported reversible biochemical changes in the head of spermatozoa which can make fertilization difficult.
4.7 Effects on ability to drive and use machines
Molap may cause dizziness. Patients should be warned not to drive or operate machinery if they experience dizziness or related symptoms.
4.8 Undesirable effects
Data from large clinical studies (internal and published) are used to determine the frequency of very common to uncommon side effects
Very common >1/10
Common > 1/100, <1/10
Uncommon > 1/1000, <1/100
Rare > 1/10000, <1/1000
Very rare <1/10000
Not known
Cannot be estimated from the available data
Molap is generally well tolerated. Some individuals may experience minor side effects which are related to its known pharmacological action of peripheral vasodilation. Such effects, indicated by a hash (#), are usually transient and usually disappear with continued administration of Molap at the same dosage.

Reporting of suspected adverse reaction
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard
4.9 Overdose
Symptoms:
There have been no recorded cases of Molap overdosage. The expected symptoms could comprise prolonged peripheral vasodilation associated with hypotension and tachycardia. Bradycardia or prolonged AV conduction could occur.
Therapy:
There is no specific antidote. Standard general measures for monitoring cardiac function and appropriate supportive and therapeutic measures should be used.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: dihydropyridine derivatives, ATC-code: C08CA09
Lacidipine is a specific and potent calcium antagonist with a predominant selectivity for calcium channels in the vascular smooth muscle. Its main action is to dilate peripheral arterioles, reducing peripheral vascular resistance and lowering blood pressure.
In a study of ten patients with a renal transplant, lacidipine has been shown to prevent an acute decrease in renal plasma flow and glomerular filtration rate about six hours after administering oral cyclosporin. During the trough phase of cyclosporin treatment, there was no difference in renal plasma flow and glomerular filtration rate between patients with or without lacidipine.
Following the oral administration of 4 mg lacidipine to volunteer subjects, a minimal prolongation of QTc interval has been observed (mean QTcF increase between 3.44 and 9.60 ms in young and elderly volunteers).
This was not associated with any adverse clinical effects or cardiac arrhythmias on monitoring.
5.2 Pharmacokinetic properties
Absorption
Lacidipine is a highly lipophilic compound; it is rapidly absorbed from the gastrointestinal tract following oral dosing.
Absolute bioavailability averages about 10% due to extensive first-pass metabolism in the
liver.
Peak plasma concentrations are reached between 30 and 150 minutes.
Elimination
The drug is eliminated primarily by hepatic metabolism (involving cytochrome P450 CYP3A4). There is no evidence that lacidipine causes either induction or inhibition of hepatic enzymes.
The principal metabolites possess little, if any, pharmacodynamic activity.
Approximately 70% of the administered dose is eliminated as metabolites in the faeces and the remainder as metabolites in the urine.
The average terminal half-life of lacidipine ranges from between 13 and 19 hours at steady state.
5.3 Preclinical safety data
The only significant toxicological findings with lacidipine were reversible and consistent with the known pharmacological effects of calcium antagonists at high doses - decreased myocardial contractility and gingival hyperplasia in rats and dogs and constipation in rats.
In rats treated at high doses (15mg/kg bw with a NOAEL of 2.5 mg/kg bw) up to Day 14 of gestation, intra-uterine deaths occurred and placental weights were increased. In rabbits treated at high doses (18mg/kg bw with a NOAEL of 9 mg/kg bw) between days 6 and 18 of gestation, there was a reduction in fetal weights. In rats treated before littering and during lactation, there was a reduction in body weight gain of the offspring from day 7 post partum up to weaning with concomitant effects on physical development.
In rats at high doses, an inhibitory action on intense uterine contractions was observed.
Lacidipine has no genotoxic potential in a battery of in vitro and in vivo tests. There was no evidence of carcinogenicity in mice. As with other calcium channel antagonists, a carcinogenicity study has shown an increase in benign interstitial cell tumors in rat testes.
The endocrine mechanisms believed to be involved in the production of interstitial hyperplasia and adenomas in rats are not relevant to humans
