NIFEDIPINE, treat heart diseases, high blood pressure indication

  • The drug is used to treat heart diseases associated with insufficient oxygen supply to the heart muscle and to treat high blood pressure.
  • The drug is used in
    • Symptoms (e.g. pain or tightness in the chest area) in conditions with insufficient oxygen supply to the heart muscle (angina pectoris):
      • under stress: chronically stable angina pectoris (stress angina)
      • due to vasospasm: vasospastic angina pectoris (Prinzmetal's angina, variant angina)
    • non-organic hypertension
    • hypertensive crisis
  • Notice:
    • In patients with non-organ related hypertension or chronic angina pectoris treated with nifedipine immediate-release formulations (this preparation is one of them), there is evidence of a dose-dependent increase in cardiovascular complications (e.g. myocardial infarction) and an increase resulting in mortality. Therefore, the drug should only be used in these two diseases if other drugs are not indicated.

NIFEDIPINE, treat heart diseases, high blood pressure dosage

  • Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
  • Treatment should be individualized as much as possible, depending on the severity of the disease and the patient's response.
  • Depending on the clinical picture in question, the recommended dose should be gradually reached.
  • Patients with severe problems with blood flow to the brain (cerebrovascular disease) should be treated with a lower dose.
  • An adjustment of the nifedipine dose may be necessary if other medicinal products that inhibit or enhance a certain enzyme system (cytochrome P450 3A4) are used concomitantly.
  • dosage
    • Unless otherwise prescribed by the doctor, the usual dose for adults is:
      • Coronary heart disease
        • high blood pressure

NIFEDIPINE, treat heart diseases, high blood pressure interactions

  • When taking the preparation with other medicines
    • Tell your doctor or pharmacist if you are taking/using, have recently taken/used or might take/use any other medicines.
    • What other medicines affect the way this medicine works?
      • Nifedipine (the active ingredient in this medicine) is broken down with the participation of a specific enzyme system (cytochrome P450 3A4). Therefore, the concomitant use of drugs that affect this enzyme system can, in principle, lead to interactions of these drugs with the preparation.
      • Both the extent and duration of interactions should be considered if the drug is to be taken with the drugs listed below.
      • Weakening of the effect of other medicines:
        • Phenytoin (active substance used to treat cardiac arrhythmias and epilepsy): Reduces the effectiveness of nifedipine. If both drugs are taken at the same time, the reaction to nifedipine (the active ingredient in this drug) should be observed and an increase in the dose of this drug should be considered if necessary. After stopping the use of phenytoin, the dose of nifedipine may need to be adjusted again.
        • Carbamazepine and phenobarbital (active substances used to treat epilepsy): Taking this medicine at the same time can lead to a weakened effect of the preparation.
        • Rifampicin (anti-tuberculosis medicine): Causes the body to break down nifedipine (the active ingredient in this medicine) more quickly. Rifampicin must not be used concomitantly with treatment with nifedipine, since effective blood levels of nifedipine are not achieved.
      • Enhancement of the nifedipine effects and side effects by other drugs:
        • If you are using the following other medicines concomitantly with this product, blood pressure should be monitored and a reduction in the dose of Nifedipine ratiopharm 20 mg/ml considered, if necessary:
          • Certain antibiotics (e.g. erythromycin)
          • fluoxetine and nefazodone (anti-sad mood remedies, antidepressants)
          • Ritonavir (anti-HIV medicine)
          • Certain antifungal medicines (e.g. ketoconazole)
          • Quinupristin / Dalfopristin (antibiotics)
          • cimetidine (medicine against stomach and intestinal ulcers)
          • valproic acid (anti-epilepsy medicine)
          • tricyclic antidepressants (medicines for depression)
          • vasodilators (medicines that dilate blood vessels)
          • cisapride (drug that speeds up bowel movement)
    • How does this preparation affect the effects of other medicines?
      • Antihypertensive drugs:
        • The blood pressure-lowering effect of other medicines of different active substance groups can be increased by this preparation, e.g. B. from:
          • Diuretics (water pills)
          • beta-receptor blockers (medicines for high blood pressure)
          • ACE inhibitors (medicines for high blood pressure)
          • angiotensin receptor antagonists (medicines for high blood pressure)
          • other calcium antagonists (medicines for high blood pressure)
          • alpha-receptor blockers (medicines for high blood pressure and heart failure)
          • PDE 5 inhibitors (medicines to treat erectile dysfunction)
          • Alpha-methyldopa (medicine for high blood pressure)
        • In the case of simultaneous treatment with beta-receptor blockers (active substance group of antihypertensive drugs), signs of heart failure may occasionally occur. Your doctor will carefully monitor the course of treatment in these cases.
      • Digoxin (active ingredient to strengthen the heart), theophylline (active ingredient to widen the bronchi): The concentration of these medicines in the blood may increase. Signs of digoxin overdose should be observed and, if necessary, the digoxin dose reduced by the doctor (after determining the digoxin concentration in the blood).
      • Vincristine (active ingredient for the treatment of tumours): The excretion of vincristine is reduced, which can increase the side effects of vincristine. Your doctor may prescribe a reduction in the dose of vincristine.
      • Cephalosporins (drugs used to treat infections): levels of cephalosporins in the blood may be increased.
      • Quinidine (active substance for the treatment of cardiac arrhythmias): In individual cases, the preparation causes a drop in the quinidine content in the blood or the discontinuation of nifedipine causes a significant increase (control of the quinidine content in the blood!). In other cases, quinidine has also been reported to increase blood levels of nifedipine. It is therefore recommended that blood pressure is carefully monitored when both drugs are used concomitantly. If necessary, the dose of this medicine should be reduced.
      • Tacrolimus (active ingredient to prevent transplant rejection after e.g. liver and kidney transplants): If nifedipine is taken at the same time, increased tacrolimus blood levels may occur, so that the tacrolimus dose should be reduced in individual cases. Regular monitoring of tacrolimus blood levels is recommended.
      • Magnesium sulfate (intravenous): When co-administered with nifedipine, an excessive fall in blood pressure may occur.
  • Take with food, drink and alcohol
    • Grapefruit juice can increase the blood pressure lowering effect of this medicine. This effect lasts for at least 3 days after the last ingestion of grapefruit juice. Consuming grapefruit or grapefruit juice should therefore be avoided in connection with the nifedipine treatment.
