For United Kingdom-based Mallinckrodt, the deal would bring a pair of currently marketed pharmaceutical products: Amitiza (lubiprostone), a medication for constipation, and Rescula (
unoprostone isopropyl ophthalmic solution 0.15%), a treatment for ocular hypertension and open-angle glaucoma.
[18] discontinued monotherapy PGA prior to starting a crossover trial of either
unoprostone and latanoprost.
Through the acquisition, Mallinckrodt adds a second commercial asset from Sucampo which is Rescula (
unoprostone isopropyl ophthalmic solution) 0.15%.

Unoprostone (Approved in 2000) [Fellman RL, Sullivan EK, Ratliff M, et al].
There are no human eye data for
unoprostone isopropyl (Rescula), a synthetic docosanoid.
The company also receives revenue from sales of Rescula (
unoprostone isopropyl) in Japan.
Unoprostone, used as the isopropyl ester for the treatment of glaucoma and ocular hypertension, is like latanoprost, a synthetic analogue of dinoprost (prostaglandin F2a).
Prostaglandin analogs (latanoprost, travoprost,
unoprostone) increase drainage of the aqueous humor.
