Amiodarone to prevent recurrence of atrial fibrillation. Cyclophosphamide-induced depression of the antioxidant defense mechanisms of the lung Venkatesan N, Chandrakasan G . Amiodarone will be given at a loading dose of 400 mg per day for two week and then lowered to 200 mg daily for 6 months at which point the dose will be lowered to 1000 mg per week.

Reduce the dose of warfarin by one-third to two-thirds if amiodarone is added, and monitor the international normalized ratio (INR) once a week for the first 7 weeks of concurrent treatment.

In about 6% of patients, amiodarone-induced pneumotoxicity (AIPT) can be seen and is dose and duration dependent.An interesting feature of our case was the rapid onset of parenchymal lesions after high-dose cyclophosphamide. The dose of amiodarone will then be lowered every six, as long as the patient has a satisfactory response. It is characterized by cough, dyspnea, fever, fatigue, reticular to reticulonodular lesions on chest radiograph and a restrictive pattern seen on pulmonary function tests. This large prospective trial demonstrated superiority of low dose amiodarone over propafenone or sotalol in preventing recurrences of AF. Atrial fibrillation (AF) is one of the most common forms of cardiac disturbances, diagnosed in an estimated 2.7 million to 6.1 million people in the United States, with prevalence increasing with age.

The potential for enhanced lung toxicity secondary to combination of amiodarone and cyclophosphamide is discussed. You are using a browser version with limited support for CSS. The incidence of thrombophlebitis, bradycardia, and hypotension was quite high, reported to be around 15% to 30% in many of the trials. At the time of admission he was being evaluated for a bone marrow transplant and had received a single dose of cyclophosphamide (4000 mg/mAn admission physical examination revealed a dyspneic man with a blood pressure of 160/80 mm Hg, pulse 90, temperature 37.1°C and a respiratory rate of 20. Hematoxylin and eosin stained, original magnification 400×.Amiodarone is increasingly being used for managing cardiac dysrhythmias.

He denied any cough, hemoptysis, fever or phlegm. (B) Chest radiograph post thoracentesis revealing normal left lung parenchyma with a minimal left pleural effusion and unchanged right lung parenchymal opacities.A left side thoracentesis performed on hospital day 2 yielded 1400 cmHistopathology of the right lung transbronchial biopsy showing mononuclear interstitial pneumonitis and intra-alveolar macrophages with granular and foamy cytoplasm (arrows), typical of amiodarone toxicity. Physicians caring for these patients should be alert to the possible enhanced lung toxicity using this combination of drugs. Study Investigators.

Treatment-related lung toxicity has been reported in 10–64% of patients who undergo antineoplastic chemotherapy for various malignancies.A 59-year-old Caucasian male with dendritic cell sarcoma was admitted to hospital with a 2 day history of progressive shortness of breath. Be aware that amiodarone has a long half-life (25–100 days); thus, interactions may occur for … In about 6% of patients, amiodarone-induced pneumotoxicity (AIPT) can be seen and is dose and duration dependent. For Atrial Fibrillation: I don't ever like taking new medicines especially those that can have severe side effects. Bone Marrow Transplantation Chest examination was significant for end inspiratory crackles in the right infrascapular region with absent breath sounds on the left side posteriorly below the mid interscapular region. Amiodarone and cyclophosphamide: potential for enhanced lung toxicity Clinically, cyclophosphamide may cause two types of lung toxicities.
