Prostacyclin's interactions in contrast to thromboxane (TXA 2), another eicosanoid, strongly suggest a mechanism of cardiovascular homeostasis between the two hormones in relation to vascular damage. Degradation. Prostacyclin, which has a half-life of 42 seconds, [5] is broken down into 6-keto-PGF 1, which is a much weaker vasodilator. Mode of action
