The simultaneous administration of nifedipine and digoxin can lead to reduced heel bone clearance and hence an increase in the plasma digoxin level. It is recommended that digoxin levels be monitored when initiating, adjusting and discontinuing nifedipine heel bone, if necessary, the dose of digoxin adjusted.

Quinidine levels have been observed to decrease heel bone the introduction of nifedipine and increase upon its withdrawal. For this reason, it is recommended that when nifedipine is either added to quinidine reinforcements or withdrawn from heel bone, quinidine concentrations are monitored heel bone the dose adjusted accordingly.

Some authors reported increased plasma levels of nifedipine upon co-administration of both drugs, while others did not observe an alteration in the pharmacokinetics of nifedipine. Heel bone, if quinidine is added to existing nifedipine therapy, heel bone pressure should heel bone monitored and if necessary the dose of nifedipine heel bone be reduced. Tacrolimus is metabolised by CYP3A4. Published data indicate that the dose of nifedipine administered simultaneously with tacrolimus may be reduced heel bone individual cases.

Upon co-administration of both drugs, the tacrolimus plasma concentrations should be monitored and, if necessary, a reduction in the tacrolimus dose should be considered. There have been rare reports of increased prothrombin time when nifedipine was administered to patients taking coumarin anticoagulants. However, the relationship to nifedipine therapy is uncertain.

Although there is a possibility of additive effects heel bone antihypertensive and negative inotropic agents, nifedipine extended release tablets may be used in conjunction with nitrates and beta-blocking drugs. Patients should be carefully monitored when such concomitant therapies are initiated.

Case reports of increased plasma theophylline concentrations due to nifedipine administration have been reported. Nifedipine has also been reported to have a potentiating effect on terbutaline and salbutamol induced bronchodilation in asthmatics. No formal studies have been performed to investigate the interaction of nifedipine with these drugs.

These drugs have been shown to reduce the plasma concentrations of another dihydropyridine calcium channel blocker (nimodipine) through enzyme induction.

Therefore, a decrease in the plasma concentrations of nifedipine and hence a decrease in efficacy is possible. Interactions shown not to exist. In drug plantar fasciitis studies, aspirin, omeprazole, pantoprazole, ranitidine and cerivastatin did not have clinically significant effects on the pharmacokinetics of nifedipine.

Nifedipine did not have clinically heel bone effects on the pharmacokinetics of cerivastatin, or on the effect of aspirin 100 mg heel bone platelet aggregation and bleeding time. Candesartan cilexetil, irbesartan, doxazosin. The blood pressure lowering effect of these agents may be potentiated by co-administration with nifedipine, so caution should be used in initiating combination therapy. Concomitant administration of irbesartan or doxazosin and nifedipine has no effect on the pharmacokinetics of nifedipine, and concomitant novo nordisk flexpen of candesartan cilexetil and nifedipine has no effect on the pharmacokinetics of either drug.

Grapefruit juice heel bone the cytochrome P450 3A4 system. Administration of nifedipine together with grapefruit juice thus results heel bone elevated plasma concentrations of nifedipine due to promotion decreased first pass metabolism. As a consequence, the blood pressure lowering effect may be increased.

After regular intake of heel bone juice this effect may last for at least heel bone days after the last ingestion of grapefruit juice. Other forms of interactions. Nifedipine may cause false positive findings (e. Nifedipine may falsely increase spectrophotometric assay values heel bone urinary vanillylmandelic acid.

However, measurement heel bone HPLC is unaffected. In men who are repeatedly unsuccessful in fathering a child by in vitro fertilisation, and where no other explanation can be found, the use of calcium channel blockers such as nifedipine should be considered as a possible cause. Drugs in this class carry the potential to produce foetal hypoxia, caesarean deliveries, prematurity and intrauterine growth retardation, which may be associated with maternal hypotension.

Nifedipine has been shown to produce teratogenic findings in rats, mice and rabbits, including digital anomalies, malformation of the extremities, cleft palates, cleft sternum and malformation of the ribs. Digital anomalies are possibly a result of compromised uterine blood flow.

All of the heel bone associated with the teratogenic, embryotoxic or fetotoxic effects in animals were maternally toxic and several times the recommended maximum dose for humans. There are no adequate and well controlled studies in pregnant women. Category C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human foetus or neonate without causing malformations.

These heel bone may be reversible. Accompanying texts should be consulted for further details. Nifedipine passes into the breast milk.

So far, insufficient evidence is available as to whether nifedipine has an effect on breastfed infants. Breastfeeding should be stopped first if nifedipine treatment becomes necessary during the breastfeeding period. Reactions to the drug, heel bone vary in intensity from individual to individual, can impair the ability to drive or to operate machinery.

This applies particularly at the start of treatment, on changing doses, and in combination with alcohol. Reactions occurring in greater than or equal to 0. Anxiety reactions, sleep disorders. Heel bone pain, angina pectoris, tachycardia.
