Substitution of vasorelaxant mediators. Analogues of prostacyclin (from vascular endothelium), such as iloprost, or of prostaglandin E i. such as alprostadil, stimulate the corresponding receptors organic nitrates (p. 124) substitute for endothelial NO. 

There are experiences of ambulatory treatment of patients with pulmonary hypertension, with inhaled nitric oxide and with prostaglandins, in both cases using an ambulatory delivery system. In our center we have an outpatient treatment program of pulmonary hypertension with inhaled iloprost leading in some patients to significant improvement in pulmonary hypertension and in the quality of life with no adverse effects. 

It should be noted that, whereas most of the agonists described at EP, receptors are obvious derivatives of PGE2 (with the exception of iloprost), none of the antagonists thus far described bear any clear chemical resemblance to E series prostaglandins.

The specificity of IA and antibody immobilization on solid-phase support techniques can be utilized for sample clean-up and concentration before capillary electrophoresis and mass spectrophotometry. For example, analysis of prostacyclins requires sensitivity in the pg/mL range and selectivity from multiple endogenous prostaglandin compounds. Immunoaffinity sample clean-up before GCMS has been used for thromboxane B2 analogs (244-246), iloprost (247), and nocloprost (248). Immunoaffinity sample clean-up before HPLC determinations was reported for clenbuterol (249) and pravastatin (250).

The increase in vascular permeability is enhanced by prostaglandin Ej (PGE2) and is suppressed by lipoxin A4. Pharmacologic agents, such as glucocorticoids, iloprost, and terbutaline, inhibit the vascular permeability response to LTB4.
