Nifedipine adalate effets secondaires Nombreux sont les médicaments qui lors de leurs usage entraînent des effet secondaires tel est Adalat Comprimé cas d’adalate nifedipine. Les effets indésirables probables sont: The interaction between cimetidine and nifedipine is of clinical relevance and blood pressure should be monitored and a reduction of the dose of nifedipine considered.

Simultaneous administration of cisapride and nifedipine may lead to increased plasma concentrations of nifedipine. Erythromycin, a CYP3A inhibitor, can inhibit the metabolism of nifedipine and increase the exposure to nifedipine during concomitant therapy.

The impact of multiple oral doses of mg rifampin on the pharmacokinetics of nifedipine after a single oral dose of 20 mg nifedipine capsule was evaluated in a clinical study, Adalat Comprimé.

Twelve healthy male volunteers received a single oral dose of 20 mg nifedipine capsule on study Day 1. Starting on study Day 2, the subjects received mg rifampin once daily for 14 days. On study Day 15, a second single oral dose of 20 mg nifedipine capsule was administered together with the last dose of rifampin.

Antiviral Drugs Amprenavir, atanazavir, delavirine, Adalat Comprimé, fosamprinavir, indinavir, nelfinavir and ritonavir, as CYP3A inhibitors, Adalat Comprimé, can inhibit the metabolism of nifedipine and increase the exposure to nifedipine.

Caution is warranted and clinical monitoring of patients recommended. Blood pressure should be monitored and a reduction of the dose of nifedipine considered. Fluoxetine, a CYP3A inhibitor, can inhibit the metabolism of nifedipine and increase the exposure to nifedipine during concomitant therapy.

Valproic acid may increase the exposure to nifedipine during concomitant therapy. Phenytoin, Phenobarbital, Adalat Comprimé, and Carbamazepine: Nifedipine is metabolized by CYP3A.

Phenobarbital and carbamazepine are also inducers of CYP3A. Alternative antihypertensive therapy should be considered in patients taking phenytoin, phenobarbital, and carbamazepine, Adalat Comprimé.

In patients taking dolasetron by the oral or intravenous route and nifedipine, Adalat Comprimé, no effect was shown on the clearance of hydrodolasetron. Tacrolimus has been shown to be metabolized via the CYP3A system. Nifedipine has been shown to inhibit the metabolism of tacrolimus in vitro. Nifedipine can Adalat Comprimé the exposure to tacrolimus.

When nifedipine is co-administered with tacrolimus the blood concentrations of tacrolimus should be monitored and a reduction of the dose of tacrolimus considered. A single 60 mg dose of nifedipine and a single 10 mg dose of sirolimus oral solution were administered to 24 healthy volunteers.

Clinically significant pharmacokinetic drug interactions were not observed. Glucose Lowering Drugs Pioglitazone: Co-administration of pioglitazone for 7 days with 30 mg nifedipine ER administered orally q.

In view of the high Adalat Comprimé of nifedipine pharmacokinetics, the clinical significance of this finding is unknown. Co-administration of rosiglitazone 4 mg b. Tmax and half-life were unaffected, Adalat Comprimé.

Nifedipine appears to enhance the absorption of metformin. No effect of miglitol was observed on the pharmacokinetics and pharmacodynamics of nifedipine, Adalat Comprimé. Co-administration of Adalat Comprimé mg nifedipine with a single dose of 2 mg repaglinide after Adalat Comprimé days nifedipine 10 mg t.

Nifedipine tends to produce hyperglycemia and may lead to loss of glucose control. If nifedipine is co-administered with acarbose, blood glucose levels should be monitored carefully and a dose adjustment of nifedipine considered.

Drugs Interfering with Food Absorption Orlistat: In 17 normal-weight subjects receiving orlistat mg t.

Dietary Supplements Grapefruit Juice: In healthy volunteers, Adalat Comprimé, a single dose co-administration of mL double strength grapefruit juice with 10 mg nifedipine increased AUC and Cmax by factors of 1.

Ingestion of repeated doses of grapefruit juice 5 x mL in 12 hours after administration of 20 mg nifedipine ER increased AUC and Cmax of nifedipine by a factor of 2. Grapefruit juice should be avoided by patients on nifedipine.

The intake of grapefruit juice should be stopped at least 3 days prior to initiating patients on nifedipine.

Alternative antihypertensive therapy should be considered in patients in whom St. John’s Wort therapy is necessary. In healthy volunteers, pretreatment with nifedipine 20 mg t. Thus, it is improbable that nifedipine inhibits in vivo the metabolism of other drugs that are substrates of CYP2D6.

Warnings WARNINGS Excessive Hypotension Although in most patients the hypotensive effect of nifedipine is modest and Adalat Comprimé tolerated, occasional patients have had excessive and poorly tolerated hypotension. These responses have usually occurred during initial titration or at the time of subsequent upward dosage adjustment, and may be more likely in patients using concomitant beta-blockers. The interaction with high dose fentanyl Adalat Comprimé to be due to the combination of nifedipine and a beta-blocker, but the possibility that it may occur with nifedipine alone, with low doses of fentanyl, in other surgical procedures, or with other narcotic analgesics cannot be ruled out, Adalat Comprimé.

Important Information

In nifedipine-treated patients where surgery using high dose fentanyl anesthesia is contemplated, the physician should be aware of these potential problems and, if the patient’s condition permits, sufficient time at least 36 hours should be allowed for nifedipine to be washed out of the body prior to surgery.

The mechanism of this effect is not established. Beta-Blocker Withdrawal Adalat Comprimé discontinuing a beta-blocker it is important to taper its dose, Adalat Comprimé, if possible, rather than stopping abruptly before beginning nifedipine.

Patients recently withdrawn from beta blockers may develop a withdrawal syndrome with increased angina, probably related to increased sensitivity to catecholamines.

Initiation of nifedipine treatment will not prevent this occurrence and on occasion has been reported to increase it.

Congestive Heart Failure Rarely, patients usually while receiving a beta-blocker have developed heart failure Adalat Comprimé beginning nifedipine. Patients with tight aortic stenosis may be at greater risk for such an event, as the unloading effect of nifedipine would be expected to be of less benefit to these patients, owing to their fixed impedance to flow across the aortic valve. Precautions General Hypotension Because nifedipine decreases peripheral vascular resistance, careful monitoring of blood pressure during the initial administration and titration of Adalat CC is suggested.

This edema is a localized phenomenon, thought to be associated with vasodilation of dependent arterioles and Adalat Comprimé blood vessels and not due to left ventricular dysfunction or generalized fluid retention. With patients whose hypertension is complicated by congestive heart failurecare should be taken to differentiate this peripheral edema from the effects of increasing left ventricular dysfunction. Use In Cirrhotic Patients Clearance of nifedipine is reduced and systemic exposure increased in patients with cirrhosis.

It is unknown how systemic exposure may be altered in patients with moderate or severe liver impairment. The relationship to nifedipine therapy is uncertain in most cases, but probable in some. These laboratory abnormalities have rarely been associated with clinical symptoms; however, cholestasis Adalat Comprimé or without jaundice has been reported.

This was an isolated finding and it rarely resulted in values which fell outside the normal range. Rare instances of allergic hepatitis have been reported with nifedipine treatment. In controlled studies, Adalat CC did not adversely affect serum uric acidglucose, cholesterol or potassium.

Nifedipine, like other calcium channel blockersdecreases platelet aggregation in vitro. Limited clinical studies have demonstrated a moderate but statistically significant decrease in platelet aggregation and increase in bleeding time in Adalat Comprimé nifedipine patients. This is thought to Adalat Comprimé a function of inhibition of calcium transport across the platelet membrane.

No clinical significance for these findings has been Adalat Comprimé. Positive direct Coombs’ test with or without hemolytic anemia has been reported but a causal relationship between nifedipine administration and positivity of this laboratory test, including hemolysiscould not be determined. Although nifedipine has been used safely in patients with renal dysfunction and has been reported to exert a Adalat Comprimé effect in certain cases, rare reversible elevations in BUN and serum creatinine have been reported in patients with pre-existing chronic renal insufficiency, Adalat Comprimé.

The relationship to nifedipine therapy is uncertain in most cases but probable in some. Carcinogenesis, Mutagenesis, Impairment Of Fertility Nifedipine was administered orally to rats for two years and was not shown to be carcinogenic. When given to rats prior to mating, nifedipine caused reduced fertility at a dose approximately 30 times the maximum recommended human dose. There is a literature report of reversible reduction in the ability of human sperm obtained from a Adalat Comprimé number of infertile men taking recommended doses of nifedipine to bind to and fertilize an ovum in vitro.

In vivo mutagenicity studies were negative. Pregnancy Pregnancy Category C In rodents, rabbits and monkeys, nifedipine has been shown to have a variety of embryotoxic, placentotoxic, teratogenic and fetotoxic effects, including stunted fetuses rats, mice and rabbitsAdalat Comprimé, digital anomalies rats and rabbitsrib deformities micecleft palate micesmall placentas and underdeveloped Adalat Comprimé villi monkeysembryonic and fetal deaths rats, mice and rabbitsprolonged pregnancy rats; not evaluated in other speciesand decreased neonatal survival rats; not evaluated in other species.

The digital anomalies seen in nifedipine-exposed rabbit pups are strikingly similar to those seen in pups exposed to phenytoin, and these are in turn similar to the phalangeal deformities that are the most common malformation seen in human children with in utero exposure to phenytoin.

From the clinical evidence available, a specific prenatal risk has not been identified, Adalat Comprimé. However, Adalat Comprimé increase in perinatal asphyxia, caesarean delivery, prematurity and intrauterine growth retardation have been reported. Careful monitoring of blood pressure must be exercised in pregnant women, Adalat Comprimé administering nifedipine in combination with IV magnesium sulfate due to the possibility of an excessive fall in blood pressure which could harm the mother Adalat Comprimé fetus.

There are no adequate and well-controlled studies in pregnant women. Nursing Mothers Nifedipine is excreted in human milk. Nursing mothers are advised not to breastfeed their babies when taking the drug. Pediatric Use The safety and effectiveness of Adalat CC in pediatric patients have not been established.

Pharmacokinetics and Metabolismclinical studies of nifedipine did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in Adalat Comprimé between the elderly and younger patients.

In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Patients With Galactose Intolerance Since this Adalat Comprimé product contains lactose, patients with rare hereditary problems of galactose intolerance, Adalat Comprimé, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.

Symptoms associated with severe Adalat Comprimé overdosage include loss of consciousness, drop in blood pressure, heart rhythm disturbances, metabolic acidosis, hypoxiacardiogenic shock with pulmonary edema. Generally, overdosage with nifedipine leading to pronounced hypotension calls for active cardiovascular support including monitoring of cardiovascular and respiratory function, elevation of extremities, judicious use of calcium infusion, pressor agents and fluids.

After oral ingestion, thorough gastric lavage is indicated, if necessary in combination with irrigation of the small intestine. In cases involving overdosage of a slowrelease product like nifedipine, elimination must be as complete as possible, including from the small intestine, to prevent the subsequent absorption of the active substance.

Additional liquid or volume must be administered with caution because of the risk of fluid overload. Clearance of nifedipine would be expected to be prolonged in patients with impaired liver function. Since nifedipine is highly protein bound, Adalat Comprimé, dialysis is not likely to be of any benefit; however, plasmapheresis may be beneficial. There has been one reported case of massive overdosage with tablets of another extended release formulation of nifedipine.

The main effects of ingestion of approximately mg of nifedipine in a young man attempting suicide as a result of cocaine -induced depression was initial dizziness, palpitationsflushing, and nervousness.
