AL 8810 is a selective FP prostanoid receptor antagonist used primarily in medical and pharmacological research. It is employed to study the mechanisms of prostaglandin F2α (PGF2α) receptors, which are involved in processes such as inflammation, pain, and ocular physiology. By blocking FP receptors, AL 8810 helps investigate its effects on intraocular pressure (IOP) and related eye pathways, playing a key role in the development of treatments for conditions like glaucoma.

Additionally, AL 8810 is utilized in research to elucidate the roles of prostaglandins in various physiological and pathological processes throughout the body, offering insights into potential therapeutic applications beyond ophthalmology.
