Action
Description: Latanoprostene bunod is a nitric oxide-donating synthetic analogue of naturally occurring prostaglandin F2α. It is a prodrug and thought to increase the outflow of aqueous humour through both the trabecular meshwork (conventional route mediated by nitric oxide) and uveoscleral pathway (nonconventional route mediated by latanoprost acid), thus lowering the intraocular pressure.
Onset: Reduction of intraocular pressure: Approx 1-3 hours; 11-13 hours (max effect). Pharmacokinetics: Absorption: Time to peak plasma concentration: Approx 5 minutes (latanoprost acid). Metabolism: Rapidly metabolised in the eye to latanoprost acid (active metabolite; F2α prostaglandin analogue) and butanediol mononitrate. Latanoprost acid is further metabolised mainly in the liver after reaching the systemic circulation via fatty acid β-oxidation to 1,2-dinor and 1,2,3,4-tetranor metabolites. Butanediol mononitrate is metabolised to 1,4-butanediol and nitric oxide; 1,4-butanediol undergoes further oxidation to form succinic acid and enters tricarboxylic acid (TCA) cycle. |
