Overview
11 DESCRIPTION Tafluprost is a fluorinated analog of prostaglandin F2α. The chemical name for tafluprost is Propan-2-yl (5 Z )-7-{(1 R ,2 R ,3 R ,5 S )-2-[(1 E )-3,3 difluoro-4-phenoxybut-1-enyl]-3,5-dihydroxycyclopentyl}hept-5-enoate. The molecular formula of tafluprost is C 25 H 34 F 2 O 5 and its molecular weight is 452.5.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Tafluprost acid, a prostaglandin analog is a selective FP prostanoid receptor agonist which is believed to reduce intraocular pressure by increasing uveoscleral outflow. The exact mechanism of action is unknown at this time. 12.3 Pharmacokinetics Absorption Following instillation, tafluprost is absorbed through the cornea and is hydrolyzed to the biologically active acid metabolite, tafluprost acid. Following instillation of one drop of the 0.0015% solution once daily into each eye of healthy volunteers, the plasma concentrations of tafluprost acid peaked at a median time of 10 minutes on both Days 1 and 8. The mean plasma C max of tafluprost acid were 26 pg/mL and 27 pg/mL on Day 1, and Day 8, respectively.
Indications
- 1 INDICATIONS AND USAGE Tafluprost ophthalmic solution, 0.0015% is indicated for reducing elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension. Tafluprost ophthalmic solution, 0.0015% is a prostaglandin analog indicated for reducing elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension. ( 1 )
Common Doses
- Refer to label
Dosage
2 DOSAGE AND ADMINISTRATION The recommended dose is one drop of tafluprost ophthalmic solution in the conjunctival sac of the affected eye(s) once daily in the evening. The dose should not exceed once daily since it has been shown that more frequent administration of prostaglandin analogs may lessen the intraocular pressure lowering effect. Reduction of the intraocular pressure starts approximately 2 to 4 hours after the first administration with the maximum effect reached after 12 hours.
Contraindications
- 4 CONTRAINDICATIONS None. None. ( 4 )
Side Effects
- 6 ADVERSE REACTIONS Most common ocular adverse reaction is conjunctival hyperemia (range 4% – 20%).
