Dosage Forms

Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

Solution, Ophthalmic [preservative free]:

Zioptan: 0.0015% (10 ea, 30 ea) [contains disodium edta, polysorbate 80]

Brand Names: U.S.

  • Zioptan

Pharmacologic Category

  • Ophthalmic Agent, Antiglaucoma
  • Prostaglandin, Ophthalmic


Tafluprost acid is a fluorinated prostaglandin F2-alpha analog believed to reduce intraocular pressure by increasing outflow of aqueous humor via the uveoscleral pathway; exact mechanism by which it reduces IOP is unknown.


Through the cornea


Ester prodrug (tafluprost) is hydrolyzed to the biologically active acid metabolite (tafluprost acid); tafluprost acid metabolized further via fatty acid beta oxidation and phase II conjugation

Onset of Action

Reduction of intraocular pressure (IOP): 2 to 4 hours; Peak effect: Maximum reduction of IOP: ~12 hours

Time to Peak

Plasma: ~10 minutes

Use: Labeled Indications

Elevated intraocular pressure: Reduction of intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension.


There are no contraindications listed in the manufacturer’s prescribing information.

Dosing: Adult

Elevated intraocular pressure: Ophthalmic: One drop in the affected eye(s) once daily in the evening; do not exceed the once daily dosage because it has been shown that more frequent administration may decrease the IOP-lowering effect

Dosing: Geriatric

Refer to adult dosing.


For ophthalmic use only. Wash hands before use. Avoid touching the tip of the single-use container to eye or other surfaces. Each single-use container has adequate solution to treat both eyes (if applicable); discard immediately after use. If more than one topical ophthalmic drug is being used, administer the drugs at least 5 minutes apart.


Store unopened foil pouches refrigerated at 2°C to 8°C (36°F to 46°F). During shipping, may be stored at temperatures up to 40°C (104°F) for no more than 2 days; do not use if mail-order prescriptions arrive after 2 days of the dispensing date. Upon opening the foil pouch, store the single-dose containers at 20°C to 25°C (68°F to 77°F) in the foil pouch; discard unused containers after 30 days. Discard opened single-dose containers immediately after use. Protect from moisture.

Drug Interactions

Nonsteroidal Anti-Inflammatory Agents: May diminish the therapeutic effect of Prostaglandins (Ophthalmic). Nonsteroidal Anti-Inflammatory Agents may also enhance the therapeutic effects of Prostaglandins (Ophthalmic). Monitor therapy

Nonsteroidal Anti-Inflammatory Agents (Ophthalmic): May diminish the therapeutic effect of Prostaglandins (Ophthalmic). Nonsteroidal Anti-Inflammatory Agents (Ophthalmic) may enhance the therapeutic effect of Prostaglandins (Ophthalmic). Monitor therapy

Adverse Reactions

The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified.

>10%: Ophthalmic: Conjunctival hyperemia (4% to 20%)

1% to 10%:

Central nervous system: Headache (6%)

Genitourinary: Urinary tract infection (2%)

Infection: Common cold (4%)

Ophthalmic: Eye irritation (≤7%), stinging of eyes (≤7%), conjunctivitis (5%), cataract (3%), eye pain (3%), xerophthalmia (3%), blurred vision (2%), hyperpigmentation of eyelashes (2%), increased eyelash length (2%)

Respiratory: Cough (3%)

<1%, postmarketing, and/or case reports: Dyspnea, exacerbation of asthma, iris hyperpigmentation, iritis, uveitis


Concerns related to adverse effects:

• Ocular effects: May change/increase brown pigmentation of the iris, eyelid, and eyelashes; length, color, thickness, shape, and/or number of eyelashes may also be increased. Pigmentation of the iris is likely to be permanent although iris color change may not be noticeable for months to years; pigmentation of the eyelid and eyelash changes may be reversible following discontinuation of therapy. Long-term consequences and potential injury to eye are not known.

Disease-related concerns:

• Ocular disease: Use with caution in patients with intraocular inflammation, aphakic patients, pseudophakic patients with a torn posterior lens capsule, or patients with risk factors for macular edema.

Special populations:

• Pediatric: Use in pediatric patients is not recommended due to possible safety issues of increased pigmentation following long-term use.

Monitoring Parameters

Intraocular pressure; regularly examine patients who develop increased iris pigmentation

Reproductive Considerations

Ophthalmic prostaglandins, such as tafluprost, have a theoretical risk of miscarriage. To decrease this risk, agents other than tafluprost may be preferred for the treatment of glaucoma in patients planning to become pregnant (Strelow 2020). The manufacturer recommends patients of childbearing potential use effective contraception during treatment with tafluprost

Pregnancy Risk Factor C Pregnancy Considerations

Ophthalmic prostaglandins, such as tafluprost, are generally avoided during pregnancy due to a theoretical risk of miscarriage and premature labor. Agents other than tafluprost may be preferred for the treatment of glaucoma during pregnancy, especially during the first trimester. In general, if ophthalmic agents are needed in pregnancy, the minimum effective dose should be used in combination with punctal occlusion to decrease exposure to the fetus (Belkin 2020; Prum 2016; Strelow 2020).
