Drug Interactions between fluconazole and Lutrate Depot

The use of fluconazole has been rarely associated with hepatotoxicity. Reversible idiosyncratic hepatitis, cholestasis and fatal fulminant hepatic failure have been reported, the latter occurring primarily in patients with serious underlying medical conditions and taking multiple concomitant medications. Liver function tests should be performed periodically in patients with preexisting hepatic abnormalities, particularly during prolonged therapy. Treatment should be withdrawn if persistent elevations or worsening of liver enzyme levels occur.

Some azole antifungals have been associated with prolongation of the QT interval on the ECG. Rare cases of QT prolongation and torsade de pointes have been reported during postmarketing experience; such reports usually involved seriously ill patients with multiple confounding risk factors, such as structural heart disease, electrolyte abnormalities, and concomitant medications. These drugs should be administered with caution to patients with potentially proarrhythmic conditions, such as congenital/acquired QT prolongation, cardiomyopathy (especially when heart failure is present), sinus bradycardia, and existing symptomatic arrhythmias. Concomitant use with other medications that have potential to increase the risk of cardiotoxicity should be avoided.

Increased risk of developing myocardial infarction, sudden cardiac death and stroke has been reported in association with the use of GnRH agonists such as leuprolide, and triptorelin. Cardiovascular risk factors should be evaluated carefully before treatment initiation. Patients should be monitored for symptoms and signs suggestive of development or cardiovascular disease and should be managed according to current clinical practice.

Androgen deprivation therapy may prolong the QT/QTc interval. Health care providers should consider if benefits of therapy outweigh the potential risks in patients with congenital long QT syndrome, congestive heart failure, electrolyte abnormalities, or taking other drugs that can also prolong the QT interval. Consider periodic monitoring of EKG and electrolytes.

Hyperglycemia and an increased risk of developing diabetes have been reported in men receiving GnRH agonists such as leuprolide and triptorelin. Caution is advised in patients with diabetes as treatment with these agents may risk glycemic control. Monitor blood glucose and/or HbA1c periodically in patients receiving treatment.

Androgen deprivation therapy may prolong the QT/QTc interval. Health care providers should consider if benefits of therapy outweigh the potential risks in patients with congenital long QT syndrome, congestive heart failure, electrolyte abnormalities, or taking other drugs that can also prolong the QT interval. Consider periodic monitoring of EKG and electrolytes.

Fluconazole is substantially removed by hemodialysis. Plasma levels of fluconazole has been shown to reduce by 50% following 3 hours of dialysis. Fluconazole should be administered after hemodialysis.

Androgen deprivation therapy may prolong the QT/QTc interval. Health care providers should consider if benefits of therapy outweigh the potential risks in patients with congenital long QT syndrome, congestive heart failure, electrolyte abnormalities, or taking other drugs that can also prolong the QT interval. Consider periodic monitoring of EKG and electrolytes.

Decreased bone density has been reported in men who have had orchiectomy or who have been treated with a GnRH agonist analog as leuprolide. It can be anticipated that long periods of medical castration in men will have effects on bone density. Bone density loss may not be reversible. Therapy with leuprolide should be administered cautiously in patients with major risk factors for decreased bone mineral content, such as chronic alcohol and/or tobacco use, a strong family history of osteoporosis, or chronic use of drugs that can reduce bone mass (e.g., anticonvulsants, corticosteroids). Therapy beyond six months with gonadotropin-releasing hormone analogs is not recommended for patients with major risk factors for decreased bone mineral content.

Fluconazole is primarily eliminated by the kidney. Patients with renal impairment may be at greater risk for adverse effects from fluconazole due to decreased drug clearance. Dosage adjustments are recommended for patients with moderate to severe renal impairment (CrCl <= 50 mL/min) receiving multiple doses of the drug.

Convulsions have been observed in patients taking leuprolide, including patients who have a history of seizures, epilepsy, or brain disorders, and in those taking medications associated with convulsions. Convulsions have also been reported in patients without any of these conditions. Caution is advised in patients with a history of seizures.
