| The
drug Remodulin is effective in patients with primary pulmonary hypertension, according
to an article in the February issue of Cardiovascular Pharmacology. Remodulin
(treprostinil) is a longer-lasting alternative to intravenous prostacyclin, according
to its manufacturer United Therapeutics. Remodulin received U.S. Food and Drug
Administration last spring as a continuous subcutaneous infusion for the treatment
of pulmonary arterial hypertension. The
article summarizes three pilot clinical trials that evaluated the effects of Remodulin
in the management of primary pulmonary hypertension. In
the first trial, the intravenous prostacyclin epoprostenol (Flolan) and intravenous
Remodulin were compared, while the second trial compared intravenous Remodulin
and subcutaneous Remodulin. In the third trial, subcutaneous Remodulin was compared
with a placebo. In
all three studies, patients with primary pulmonary hypertension receiving Remodulin
had reductions in their pulmonary arterial pressures and experienced other favorable
improvements in their blood circulation measurements. In
addition, patients receiving subcutaneous Remodulin showed clinically significant
improvement in their exercise capacity. Adverse effects reported (headache, diarrhea,
flushing) were similar to those reported with chronic intravenous epoprostenol
therapy. Patients receiving chronic subcutaneous Remodulin infusions also reported
erythema and pain at the infusion site. Other
