1. What is Lacerol and what is it used for
Lacerol belongs to a group of medications called calcium channel blockers. They work by dilating blood vessels and reducing the heart's oxygen needs.
This medication is used for:
? Treatment and prevention of chest angina, including Prinzmetal's angina (vasospastic angina).
? Treatment of high blood pressure (hypertension).
2. What you need to know before starting to take Lacerol
Do not take Lacerol
- if you are allergic to diltiazem or any other component of this medication (listed in section 6),
- in case of shock
- if you have any heart disease, such as left ventricular insufficiency with pulmonary congestion
- if you have severe low blood pressure (severe hypotension)
- if you have had a heart attack
- if you have certain heart rhythm disorders, such as: bradycardia - less than 40 beats/minute -, second- or third-degree block in patients without a pacemaker, sick sinus node disease in patients without a pacemaker
- if you are being treated with dantrolene in perfusion (a medication to relax muscles).
- if you are already taking a medication that contains ivabradina for the treatment of certain heart diseases
if you are taking a medication that contains lomitapida, used to treat 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 woman of childbearing age and are not using 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 insufficiency, bradycardia (slow heart rate), or first-degree atrioventricular block (a type of heart rhythm disorder) detected by electrocardiogram, your doctor will need to closely monitor you.
- in case of general anesthesia, you should inform the anesthesiologist that you are being treated with this medication.
- if you are an elderly patient or have kidney or liver disease (renal or hepatic insufficiency), diltiazem blood levels may be higher, so your heart rate will need to be closely monitored at the start of treatment.
- if you experience 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 of toxic compounds in the liver, including porphyrins and their precursors).
- if you have low blood pressure: treatment with diltiazem may cause excessive blood pressure drop. Your doctor will inform you about how to avoid symptoms resulting from hypotension and what measures to take if these symptoms occur.
- the use of diltiazem has been associated with skin reactions. Your doctor will assess these symptoms and indicate the measures to take.
- diltiazem has significant hepatic metabolism, being excreted by the kidneys as well as by bile. Like other medications administered for prolonged periods, laboratory parameters should be regularly monitored.
- It can cause an increase in liver enzymes, which is usually reversible if treatment is discontinued. Your doctor will perform periodic checks.
- If you have a history of heart failure, new difficulty breathing, slow heartbeats, or low blood pressure. Cases of kidney damage have been reported in patients with these conditions; your doctor may need to monitor your kidney function.
Children and adolescents
The efficacy and safety of use in children have not been established. Therefore, the use of Lacerol is not recommended in children and adolescents (under 18 years of age).
Other medications and Lacerol
Inform your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication.
Contraindicated use:
- Dantrolene: the simultaneous use of diltiazem with dantrolene (in perfusion) is contraindicated.
- Ivabradina (see section "Do not take Lacerol").
- Medications containing lomitapida used to treat high cholesterol levels. Diltiazem can increase lomitapida concentration and may increase the likelihood and severity of liver-related side effects.
- Effects of other medications on Lacerol
The following medications can increase the effects of Lacerol by increasing its blood concentration:
- 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 can decrease the effects of Lacerol by reducing its blood concentration:
- phenytoin (used to treat epilepsy)
- St. John's Wort (used for fatigue, tiredness, or sleep disorders)
- rifampicin (antibiotic)
- Effects of Lacerol on other medications
Lacerol can increase the effects of the following medications by increasing their blood concentrations or enhancing their effect:
- phenytoin, carbamazepine (used to treat epilepsy),
- midazolam, triazolam, buspirone (used to treat anxiety),
- digoxin (used to treat heart diseases),
- cyclosporine, sirolimus (used to suppress the immune system),
- methylprednisolone (corticosteroid used to treat inflammatory disorders),
- simvastatin and lovastatin (medications to reduce cholesterol and other fatty substances in the blood),
- theophylline (used to treat asthma)
- medications that reduce blood clot formation (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 illnesses): may increase the risk of intense agitation (psychotic episodes)
- X-ray contrast medium: patients treated with diltiazem may experience increased cardiovascular effects, such as hypotension, when administered an intravenous bolus of an ionic X-ray contrast medium. Special caution is required in patients who receive concomitant diltiazem and X-ray contrast medium.
General information to keep in mind:
- Antiplatelet medications (medications that prevent platelet aggregation): the possibility of an additive effect on platelet aggregation of diltiazem and antiplatelet medications (such as acetylsalicylic acid, ticagrelor, cilostazol) should be considered.
- Medications metabolized by the CYP3A4 enzyme, as this may result in a decrease in diltiazem blood levels or an increase in the levels of any medications administered with it.
- Patient monitoring is recommended for those consuming grapefruit juice, as it may increase the adverse effects of diltiazem. Grapefruit juice should be avoided if an interaction is suspected.
- Cilostazol: by inhibiting cilostazol metabolism, diltiazem increases its pharmacological activity.
The combined use of Lacerol with other medications should be done under medical supervision and with gradual dose adjustment.
Taking Lacerol with food and beverages
It is recommended to take this medication preferably before meals.
Grapefruit juice should be avoided (see section "Other medications and Lacerol").
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.
This medication should not be administered to pregnant women or women of childbearing age who are not using an effective contraceptive method.
This medication should not be taken during breastfeeding, as it passes into breast milk. If the doctor considers it essential to take this medication, the baby should be fed with an alternative method.
Driving and using machines
The ability to drive and use machines may be impaired, especially at the start of treatment with diltiazem.
