Inhaled prostacyclin derivative; vasodilator; some systemic absorption with inhibition of platelet aggregation possible
Administered via specific types of nebulizer machine
Improves symptoms in patients with pulmonary arterial hypertension.

The clearance of intravenous iloprost is decreased in patients with hepatic impairment. Inhaled iloprost has not been evaluated in patients with hepatic impairment. Consider increasing the dosing interval (e.g., 3—4 hours between doses depending on the patient's response at the end of the dose interval) in patients with Child Pugh Class B or C hepatic impairment.

No dosage adjustment is required for patients with renal impairment who are not on dialysis.
Intermittent hemodialysis
Use inhaled iloprost with caution in patients on dialysis. In clinical trials, the clearance of intravenous iloprost was decreased in patients with end-stage renal failure requiring intermittent dialysis; however, inhaled iloprost has not been evaluated in patients with renal failure. The effect of dialysis on iloprost has not been evaluated.

Acetaminophen; Ibuprofen: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.

Aldesleukin, IL-2: (Moderate) Iloprost may potentiate the hypotension seen with aldesleukin, IL 2.
Alemtuzumab: (Moderate) Alemtuzumab may cause hypotension. Careful monitoring of blood pressure and hypotensive symptoms is recommended especially in patients with ischemic heart disease and in patients on antihypertensive agents.
Alfuzosin: (Moderate) The concomitant administration of alpha-blockers with other antihypertensive agents can cause additive hypotensive effects. This interaction can be therapeutically advantageous, but dosages must be adjusted accordingly.
Aliskiren: (Moderate) Aliskiren can enhance the effects of iloprost on blood pressure if given concomitantly. This additive effect may be desirable, but dosages must be adjusted accordingly. Blood pressure and electrolytes should be routinely monitored in patients receiving aliskiren.
Aliskiren; Hydrochlorothiazide, HCTZ: (Moderate) Aliskiren can enhance the effects of iloprost on blood pressure if given concomitantly. This additive effect may be desirable, but dosages must be adjusted accordingly. Blood pressure and electrolytes should be routinely monitored in patients receiving aliskiren.
Alprostadil: (Minor) Systemic alprostadil and epoprostenol are both prostaglandins that reduce blood pressure, and would not be commonly prescribed together at the same time. The concomitant use of systemic alprostadil injection and epoprostenol would be expected to cause additive hypotension. Systemic drug interactions with the urethral suppository (MUSE) or alprostadil intracavernous injection are unlikely in most patients because low or undetectable amounts of the drug are found in the peripheral venous circulation following administration. In those men with significant corpora cavernosa venous leakage, hypotension might be more likely. Use caution with in-clinic dosing for erectile dysfunction (ED) and monitor for the effects on blood pressure. However, in clinical trials with alprostadil intracavernous injection, anti-hypertensive agents had no apparent effect on the safety and efficacy of alprostadil.

Anticoagulants: (Moderate) When used concurrently with anticoagulants, inhaled iloprost may increase the risk of bleeding.
Apraclonidine: (Minor) Alpha blockers as a class may reduce heart rate and blood pressure. While no specific drug interactions have been identified with systemic agents and apraclonidine during clinical trials, it is theoretically possible that additive blood pressure reductions could occur when apraclonidine is combined with the use of antihypertensive agents. Patients using cardiovascular drugs concomitantly with apraclonidine should have their pulse and blood pressure monitored periodically.
Aripiprazole: (Minor) Aripiprazole may enhance the hypotensive effects of antihypertensive agents.

Intravenous vasopressors may be used in the emergency management of pulmonary hypertension patients when needed, but hemodynamic monitoring and careful monitoring of cardiac status are needed to avoid ischemia and other complications.
Asenapine: (Moderate) Secondary to alpha-blockade, asenapine can produce vasodilation that may result in additive effects during concurrent use of antihypertensive agents. The potential reduction in blood pressure can precipitate orthostatic hypotension and associated dizziness, tachycardia, and syncope. If concurrent use of asenapine and antihypertensive agents is necessary, patients should be counseled on measures to prevent orthostatic hypotension, such as sitting on the edge of the bed for several minutes prior to standing in the morning and rising slowly from a seated position. Close monitoring of blood pressure is recommended until the full effects of the combination therapy are known.

Spironolactone; Hydrochlorothiazide, HCTZ: (Moderate) Amiloride can have additive effects when administered with other antihypertensive agents. These effects can be used to therapeutic advantage, but dosage adjustments may be necessary.
Sulindac: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.

Endogenous prostacyclin, a metabolite of arachidonic acid, is produced by vascular endothelium. Iloprost is a stable prostacyclin analog that produces vasodilation and antiproliferative effects similar to endogenous prostacyclin. The mechanisms by which iloprost causes vasodilation are unclear. A focus of research involves the increased concentrations of intracellular cyclic adenosine monophosphate (cAMP) that occur when iloprost binds to cell surface receptors coupled to adenylate cyclase. Furthermore, iloprost has been linked to rapid decreases in atrial natriuretic peptide and cyclic guanosine monophosphate levels and increased pulmonary clearance of big endothelin-1 in pulmonary hypertension patients. These mechanisms are thought to be involved in the vasodilatory actions of iloprost. The hemodynamic effects following the relaxation of vascular smooth muscle and subsequent vasodilation by iloprost include decreased pulmonary vascular resistance, increased cardiac index, and increased oxygen delivery.
 
The actions of iloprost on platelet aggregation mimics those of endogenous prostacyclin. Iloprost stimulates adenyl cyclase, located within the platelet membrane, in turn activating the conversion of adenosine triphosphate (ATP) to cAMP which inhibits thromboxane A2 (TXA2) generation and release from the platelet. The result of inhibition of TXA2 formation and release is blockade of the secondary phases of platelet aggregation.

Iloprost is administered by inhaled aerosolized solution. Iloprost is approximately 60% protein-bound, mainly to albumin. Iloprost is metabolized, primarily via ß-oxidation, to a pharmacologically inactive metabolite. In vitro studies reveal that cytochrome P450-dependent metabolism plays a minor role in the biotransformation of iloprost. Administration of radioactively-labeled iloprost shows recovery of 68% and 12% of iloprost in urine and feces, respectively.

Limited published data from case series and case reports have not established an association with iloprost and major birth defects, miscarriage or adverse maternal or fetal outcomes when administered to pregnant women. It is not known if iloprost crosses the placenta. The molecular weight is low enough; however, the short half-life (20 to 30 minutes) should minimize fetal exposure to the drug. In Hans-Wistar rats that received intravenous iloprost at 2-times the human dose, shortened digits of the thoracic extremity occurred in fetuses and pups. In a case report, 3 women with pulmonary hypertension initiated therapy with inhaled iloprost at 8, 19, and 17 weeks gestation. One woman suffered cardiorespiratory arrest at 25 weeks gestation. A 0.65 kg male infant was delivered via cesarean section 5 days later. The other two women delivered via cesarean section at 35 and 36 weeks gestation. All 3 infants had Apgar scores of 8 or higher at 1 minute, had no congenital anomalies, and were progressing well at follow-up. Another woman with idiopathic pulmonary arterial hypertension initiated therapy with inhaled iloprost at 24 weeks gestation. The infant was delivered via cesarean section at 34 weeks due to oligohydramnios. Intravenous iloprost was administered during the perioperative period. Both the mother and baby were discharged 8 days after the delivery and were clinically well. No additional details regarding the clinical condition of infant were provided. Although iloprost has been used in pregnant women without causing fetal harm and therapy should not be withheld because of pregnancy, pregnancy is not advised in women with pulmonary hypertension because of the high risk or morbidity and death. Pregnant women with untreated pulmonary arterial hypertension are at risk for heart failure, stroke, preterm delivery, and maternal and fetal death.

It is not known if iloprost is excreted in human milk. The molecular weight is low enough for excretion, but the short plasma half-life of the drug suggests excretion will be limited. The effect of exposure on a nursing infant is unknown. According to the manufacturer, patients should be advised to not breastfeed during iloprost therapy. An alternative drug to consider may be epoprostenol. If a breast-feeding infant experiences an adverse effect related to a maternally ingested drug, healthcare providers are encouraged to report the adverse effect to the FDA.
