Contraindications
unstable angina; within 6 months of myocardial infarction; decompensated cardiac failure (unless under close medical supervision); severe arrhythmias; congenital or acquired heart-valve defects; within 3 months of cerebrovascular events; pulmonary veno-occlusive disease; conditions which increase risk of bleeding. Common side effects
In clinical studies, common adverse reactions due to inhaled iloprost included: vasodilation (flushing, 27%), cough (39%), headache (30%), flu syndrome (14%), nausea (13%), neck spasms (12%), hypotension (11%), insomnia (8%), and fainting (syncope) (8%); other serious adverse events reported with the use of Ventavis included congestive heart failure, chest pain, supraventricular tachycardia, dyspnea, swelling of the limbs (especially around the ankles and feet), and kidney failure.Serious adverse events reported with the use of inhaled iloprost include congestive heart failure, chest pain, supraventricular tachycardia, shortness of breath, peripheral edema, and kidney failure. Warnings
Iloprost as Ventavis is intended for inhalation administration only via the I-Neb AAD or Prodose AAD Systems, pulmonary drug delivery devices. It has not been studied with any other nebulizers. Vital signs should be monitored while initiating inhaled iloprost therapy. Dose adjustments or a change in therapy should be considered if exertional syncope occurs. Inhaled iloprost should not be initiated in patients with systolic blood pressure lower than 85 mm Hg. Iloprost should be stopped immediately if signs of pulmonary edema occur. This may be a sign of pulmonary venous hypertension. Iloprost has not been evaluated in patients with chronic obstructive pulmonary disease (COPD), severe asthma, or with acute pulmonary infections.
Any patient who cannot tolerate the 5 μg dose should be maintained at 2.5 μg. Each inhalation treatment requires one entire single-use ampule. Each single-use ampule delivers a concentration of 10 μg/mL to the medication chamber of either the I-Neb AAD or Prodose AAD System, and delivers a nominal dose of either 2.5 μg or 5.0 μg to the mouthpiece. After each inhalation session, any solution remaining in the medication chamber should be discarded. Use of the remaining solution, even if the reservoir is "topped off" with fresh medication, will result in unpredictable dosing. Patients should follow the manufacturers instructions for cleaning the I-Neb AAD or Prodose AAD System components after each dose administration. Complete information regarding use of iloprost in specific populations (e.g. nursing mothers, pediatrics, patients with hepatic or renal impairment), drug interactions, and overdosage can be found in full prescribing information. Intravenous
Iloprost is also available in an intravenous form, developed and marketed by Schering AG under the trade name Ilomedine. IV iloprost is usually administered diluted, via a peripheral vein or central venous catheter. The diluted iloprost should be delivered by an accurate rate delivery system such as a syringe driver. Doses vary with individuals as side effects are better tolerated by some patients than others. The duration of the treatment is typically 3 days. This is usually repeated every 8 to 12 weeks.
