Iloprost Waymade (Iloprost Trometamol)

Iloprost Waymade, a prostacyclin analog, acts on the pulmonary vascular and microvascular pathways to improve blood flow.

• Pulmonary arterial hypertension: reduces pulmonary arterial pressure and improves exercise capacity.
• Digital ulcers associated with systemic sclerosis: promotes ulcer healing and reduces pain.
• Severe Raynaud's phenomenon in systemic sclerosis: decreases frequency of attacks and improves peripheral circulation.

• Iloprost trometamol is a selective agonist of the prostacyclin (IP) receptor on vascular smooth‑muscle cells and platelets. Activation of the IP receptor stimulates cyclic‑AMP formation, leading to potent vasodilation, inhibition of platelet aggregation, and antiproliferative effects on smooth‑muscle proliferation, thereby lowering pulmonary vascular resistance and improving microcirculatory flow.

Iloprost Waymade may be associated with a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects

• Headache: mild to moderate intensity.
• Flushing: transient warmth and redness of skin.
• Nausea: occasional gastrointestinal upset.
• Diarrhea: loose stools.
• Hypotension: drop in blood pressure, especially after infusion start.
• Jaw pain: discomfort during chewing.

Serious or Rare Side Effects

• Pulmonary edema: fluid accumulation in lungs.
• Severe hypotension: marked blood pressure fall requiring intervention.
• Bleeding: increased risk due to platelet inhibition.
• Thrombocytopenia: low platelet count.
• Arrhythmias: irregular heart rhythms.
• Anaphylactic reaction: severe allergic response.

Before initiating Iloprost Waymade, clinicians should consider several precautionary measures to ensure safe use.

• Blood pressure monitoring: check baseline and during infusion to detect hypotension.
• Dose adjustment in renal or hepatic impairment: reduce infusion rate as needed.
• Concomitant vasodilators: avoid or use with caution to prevent excessive blood pressure fall.
• Bleeding risk: assess for coagulopathy or anticoagulant therapy.
• Pregnancy and lactation: safety not established; use only if benefit outweighs risk.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Iloprost Waymade can interact with other medicines, influencing its efficacy or safety profile.

Major Interactions (Avoid)

• Other prostacyclin analogs: additive vasodilatory effect may cause severe hypotension.
• Potent vasodilators (e.g., nitroglycerin): risk of profound blood pressure reduction.
• Anticoagulants (e.g., warfarin, heparin): increased bleeding tendency.

Moderate Interactions (Monitor Closely)

• CYP450 inhibitors or inducers: may alter iloprost metabolism and plasma levels.
• Aspirin or other antiplatelet agents: monitor for enhanced platelet inhibition.
• Other antihypertensives: adjust dose to maintain target blood pressure.
