Lacerol belongs to a group of medications called calcium channel blockers. They act by dilating blood vessels and at the same time reducing the heart's oxygen needs.

This medication is used for:

?The treatment and prevention of chest angina, including Prinzmetal's angina (vasospastic).

?The treatment of high blood pressure (hypertension).

Do not take Lacerol

• if you are allergic to diltiazem or any of the other ingredients in this medication (listed in section 6),
• in case of shock
• if you have any heart disease such as left ventricular heart failure with pulmonary congestion
• if you have severe low blood pressure (hypotension)
• if you are experiencing an acute myocardial infarction
• if you have certain heart rhythm disorders, such as: bradycardia (less than 40 beats per minute), blockage, second or third degree in patients without a pacemaker, sinus node disease in patients without a pacemaker
• if you are being treated with dantrolene in infusion (a medication to relax muscles).
• if you are already taking a medication that contains ivabradina for the treatment of some heart diseases

heart diseases

• if you are already taking a medication that contains lomitapida used for the treatment of high cholesterol levels (see section “Other medications and Lacerol”).
• if you are pregnant or think you may be pregnant

• if you are breastfeeding,
• if you are a fertile woman and do not use an appropriate contraceptive method.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Lacerol.

• if you have heart conditions such as left ventricular heart failure, bradycardia (slow heart rate) or first-degree atrioventricular blockage (a type of heart rhythm disorder) detected by electrocardiogram, your doctor will need to closely monitor you.
• in the case of general anesthesia, you must inform the anesthesiologist that you are being treated with this medication.
• if you are an elderly patient or if you have kidney or liver disease (renal or hepatic insufficiency), the diltiazem concentration in the blood may be higher, so you will need to closely monitor your heart rate at the beginning of treatment.
• if you perceive mood changes or are at risk of depression.
• if you are at risk of developing intestinal obstruction, as diltiazem, like other medications in the same group, can decrease intestinal movement.
• if you have diabetes mellitus, as diltiazem can increase blood sugar levels.
• if you have acute porphyria (a disease characterized by the accumulation in the liver of toxic compounds including porphyrins and their precursors).
• if you experience hypotension: treatment with diltiazem can lead to excessive lowering of blood pressure. Your doctor will inform you about how to avoid symptoms resulting from hypotension and what measures to take if these symptoms occur.
• diltiazem has been associated with skin reactions. Your doctor will evaluate these symptoms and indicate the measures to take.
• diltiazem has significant hepatic metabolism, excreted by the kidneys as well as by the bile. Like other medications administered over prolonged periods of time, laboratory parameters must be regularly monitored.
• it may cause an increase in liver enzymes, which is usually reversible if treatment is discontinued, your doctor will perform regular checks.
• if you have a history of heart failure, new difficulty breathing, slow heart rate, or low blood pressure. Cases of kidney damage have been reported in patients with these conditions, your doctor may need to monitor your renal function.

Children and adolescents

There is no established efficacy and safety of use in children. Therefore, Lacerol is not recommended for use in children and adolescents (under 18 years old).

Other medications and Lacerol

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

Contraindicated use:

• Dantrolene: the simultaneous use of diltiazem with dantrolene (in infusion) is contraindicated.
• Ivabradina (see section “Do not take Lacerol”).
• • Medications containing lomitapida used for the treatment of high cholesterol levels. Diltiazem may increase the concentration of lomitapida and may increase the likelihood and severity of side effects related to the liver

•Effects of other medications on Lacerol

The following medications may increase the effects of Lacerol by increasing its concentration in the blood:

• fluconazole and other antifungals (used to treat fungal infections),
• erythromycin and other macrolides (antibiotics),
• ritonavir (used to treat viral infections),

• amiodarone and other antiarrhythmics (used to decrease heart rate),

• cimetidine and ranitidine (used to decrease stomach acid production).

The following medications may decrease the effects of Lacerol by reducing its concentration in the blood:

• phenytoin (used to treat epilepsy)
• St. John's Wort (used in cases of weakness, fatigue, or sleep disturbances)
• rifampicin (antibiotic)

•Effects of Lacerol on other medications

Lacerol may increase the effects of the following medications by increasing their concentrations in the blood or potentiating their effect:

• phenytoin, carbamazepine (used to treat epilepsy),
• midazolam, triazolam, buspirone (used to treat anxiety),
• digoxin (used to treat heart diseases),
• ciclosporin, sirolimus (used to suppress the immune system),
• prednisolone (corticosteroid used to treat inflammatory problems),

• simvastatin and lovastatin (medications to reduce cholesterol and other fatty substances in the blood),
• theophylline (used to treat asthma)

• blood thinners (oral anticoagulants, such as acenocoumarol or warfarin),
• rifampicin (antibiotic),
• medications used to reduce blood pressure (nitrates, alpha and beta blockers, diuretics, angiotensin-converting enzyme inhibitors) and to decrease heart rate (amiodarone)
• anesthetics
• lithium salts (used to treat certain mental disorders): may increase the risk of intense agitation (psychotic episodes)
• contrast medium for X-rays: patients treated with diltiazem may experience increased cardiovascular effects, such as hypotension, when administered an intravenous bolus of an ionic contrast medium for X-rays. Special caution is required in patients who receive diltiazem and an ionic contrast medium for X-rays concomitantly.

General information to be taken into account:

• Antiplatelet medications (medications that prevent platelets from aggregating and forming a blood clot): the possibility of additive effect on platelet aggregation of diltiazem and antiplatelet medications (such as aspirin, ticagrelor, cilostazol) should be considered.

• Medications metabolized by the CYP3A4 enzyme, as this may result in a decrease in the amount of diltiazem in the blood or an increase in the amount of any medication administered with it.
• Patients who consume grapefruit juice should be monitored, as it may increase the adverse effects of diltiazem. Grapefruit juice should be avoided if an interaction is suspected.
• Cilostazol: by inhibiting the metabolism of cilostazol, diltiazem increases its pharmacological activity.

The concomitant use of Lacerol with other medications should be carried out under medical control and adjusting the doses progressively.

Taking Lacerol with food and drinks

It is recommended to take this medication preferably before meals.

Consuming grapefruit juice should be avoided (see section “Other medications and Lacerol”)
