Fluticasone propionate is a glucocorticoid with high topical anti-inflammatorypotency, but a low HPA-axis suppressive activity after dermal administration. It, therefore, has a therapeutic index which is greater than most of the commonly available steroids. Fluticasone propionate has a high degree of selectivity for the glucocorticoid receptor. In vitro studies show that fluticasone propionate has a strong affinity for, and agonist activity at, human glucocorticoid receptors. This receptor is believed to be responsible for the anti-inflammatory properties of glucocorticoids. Fluticasone propionate has weak affinity forthe progesterone receptor, andvirtually no affinity for the mineralocorticoid, estrogen, or androgen receptors. The therapeutic potency of glucocorticoids is related to the half-life of the glucocorticoid-receptor complex. The half-life of the Fluticasone propionate glucocorticoid-receptor complex is approximately 10 hours.
