Action
Description: Tafluprost is a prodrug of tafluprost acid, a fluorinated prostaglandin F2α analogue. The exact mechanism by which it reduces intraocular pressure (IOP) is unknown, but is believed to act by increasing the uveoscleral outflow of aqueous humour.
Onset: Reduction of IOP: 2-4 hr. Duration: ≥24 hr. Pharmacokinetics: Absorption: Absorbed through the cornea. Time to peak plasma concentration: Approx 10 min. Metabolism: Metabolised via hydrolysis to the biologically active metabolite, tafluprost acid, which is metabolised further via fatty acid β-oxidation and phase II conjugation. Excretion: Via urine (approx 27-38%) and faeces (approx 44-58%). |
