Inhaled Aerosolized Prostacyclin for Pulmonary Hypertension Requiring Inhaled Nitric Oxide
調査の概要
詳細な説明
Phase 1- In the original study, 3 doses of Iloprost were given. This was revised after 5 subjects were enrolled in order to study the effects of continuous delivery over a longer period of time.
Phase 2 - All remaining subjects received Iloprost as a continuous treatment.
The study was designed for an enrollment of 200 subjects and was ended early.

実験的:Phase 2: Inhaled Iloprost continuous
Each subject will have a stable dose of INO therapy as established by the attending physicians for at least one hour. Initial baseline data collection will then be made. A 20 mcg dose of Iloprost will be given initially. During this treatment there will be a nitric oxide titration to 0. Iloprost will be aerosolized continuously at a dose of 5-30mcg/hour for as long as the attending physician deems it necessary to deliver vasodilator therapy. |
A 20 mcg dose of Iloprost will be given initially.

実験的:Phase 1: Inhaled Iloprost 3 doses
Each subject will have a stable dose of INO therapy as established by the attending physicians for at least one hour. Initial baseline data collection will then be made. A 20 mcg dose of Iloprost will be given initially. During this treatment there will be a nitric oxide titration to 0. Iloprost will be aerosolized three different times on hour apart. Thirty minutes after the last iloprost dose, INO will be added back at the previous (baseline) dose. |
A 20 mcg dose of Iloprost will be given initially.
