🩺 Clinical
Tafluprost ophthalmic is used to treat glaucoma (a condition in which increased pressure in the eye can lead to gradual loss of vision) and ocular hypertension (a condition which causes increased pressure in the eye). Tafluprost is in a class of medications called prostaglandin analogs. It works to lower pressure in the eye by increasing the flow of natural eye fluids out of the eye.

⏳ Availability & generic status
FDA-approved generic versions are listed, and recent pricing/market data suggests they may be available — see Therapeutic equivalents.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

📄 Full prescribing information FDA SPL
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE ZIOPTAN® is indicated for reducing elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension. ZIOPTAN is a prostaglandin analog indicated for reducing elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension. ( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Apply one drop in the affected eye(s) once daily in the evening. ( 2 )
2.1Recommended Dosage The recommended dosage is one drop in the conjunctival sac of the affected eye(s) once daily in the evening.
2.2Administration Instructions ZIOPTAN should not be administered more than once daily since it has been shown that more frequent administration of prostaglandin analogs may lessen the intraocular pressure (IOP) 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. ZIOPTAN may be used concomitantly with other topical ophthalmic drug products to lower IOP.
If more than one topical ophthalmic product is being used, each one should be administered at least 5 minutes apart. The solution from one single-dose container is to be used immediately after opening for administration to one or both eyes. Since sterility cannot be maintained after the single-dose container is opened, discard the open single-dose container and the remaining contents immediately after administration.
💊 Dosage Forms and Strengths ▾
3 DOSAGE FORMS AND STRENGTHS Ophthalmic solution: 0.0015% tafluprost in a single-dose container. Ophthalmic solution: 0.0015% tafluprost in a single-dose container. ( 3 )
⛔ Contraindications ▾
4 CONTRAINDICATIONS None. None. ( 4 )
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS . Most common ocular adverse reaction is conjunctival hyperemia (4% to 20%). ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Thea Pharma Inc. at 1-833-838-4028 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Studies Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Preservative-containing or nonpreserved tafluprost 0.0015% was evaluated in 905 patients in five controlled clinical studies of up to 24-months duration. The most common adverse reaction observed in patients treated with tafluprost was conjunctival hyperemia which was reported in a range of 4% to 20% of patients.
Approximately 1% of patients discontinued therapy due to ocular adverse reactions. Ocular adverse reactions reported at an incidence of ≥ 2% in these clinical studies included ocular stinging/irritation (7%), ocular pruritus including allergic conjunctivitis (5%), cataract (3%), dry eye (3%), ocular pain (3%), eyelash darkening (2%), growth of eyelashes (2%) and vision blurred (2%). Nonocular adverse reactions reported at an incidence of 2% to 6% in these clinical studies in patients treated with tafluprost 0.0015% were headache (6%), common cold (4%), cough (3%) and urinary tract infection (2%).
6.2Postmarketing Experience The following adverse reactions have been identified during postapproval use of tafluprost. Because postapproval adverse reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Respiratory disorders: exacerbation of asthma, dyspnea Eye disorders: iritis/uveitis In postmarketing use with prostaglandin analogs, periorbital and lid changes including deepening of the eyelid sulcus have been observed.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS . Use in pediatric patients is not recommended because of potential safety concerns related to increased pigmentation following long-term chronic use. ( 8.4 )
8.1Pregnancy Risk Summary There are no adequate and well-controlled studies of ZIOPTAN administration in pregnant women to inform of drug-associated risks. In animal reproduction studies, intravenous administration of tafluprost to pregnant rabbits and rats throughout organogenesis resulted in embryofetal toxicities at exposures ≥5-times the human dose in rabbit and ≥2362-times the human dose in rat. (see Data).
The estimated background risk of major birth defects and miscarriage for the indicated population(s) is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Data Animal Data In embryo-fetal development studies, intravenous administration of tafluprost to pregnant rats and rabbits during organogenesis caused increases in post-implantation losses in both species and reductions in fetal body weights in rats (≥0.03 mcg/kg/day in rabbits, 5-times the maximum clinical exposure based on Cmax; ≥10 mcg/kg/day in rats, 2362-times the maximum clinical exposure based on Cmax). Tafluprost also increased the incidence of vertebral skeletal abnormalities in rats and the incidence of skull, brain and spine malformations in rabbits at these same doses.
In rats, there were no adverse effects on embryo-fetal development at a dose of 3 mcg/kg/day corresponding to maternal plasma levels of tafluprost acid that were 343 times the maximum clinical exposure based on Cmax. At the no-effect dose in rabbits (0.01 mcg/kg/day), maternal plasma levels of tafluprost acid were below the lower level of quantification (20 pg/mL). In a pre- and postnatal development study, intravenous administration of tafluprost to pregnant rats during organogenesis and through birth and lactation, caused increased mortality of newborns, decreased body weights and delayed pinna unfolding in offsprings.
The no observed adverse effect level was at a tafluprost intravenous dose of 0.3 mcg/kg/day which is greater than 3 times the maximum recommended clinical dose based on body surface area comparison.
8.2Lactation Risk Summary There are no data on the presence of tafluprost or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production following topical ocular administration. Tafluprost and/or its metabolites are present in rat milk following ocular administration. When a drug is present in animal milk, it is likely that the drug will be present in human milk.
8.4Pediatric Use Use in pediatric patients is not recommended because of potential safety concerns related to increased pigmentation following long-term chronic use.
8.5Geriatric Use No overall clinical differences in safety or effectiveness have been observed between elderly and other adult patients.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY .
12.1Mechanism 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.
12.3Pharmacokinetics . 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 Cmax of tafluprost acid were 26 pg/mL and 27 pg/mL on Day 1, and Day 8, respectively. The mean plasma AUC estimates of tafluprost acid were 394 pg*min/mL and 432 pg*min/mL on day 1 and 8, respectively. Elimination Metabolism Tafluprost, an ester prodrug, is hydrolyzed to its biologically active acid metabolite in the eye.
The acid metabolite is further metabolized via fatty acid β-oxidation and phase II conjugation. Mean plasma tafluprost acid concentrations were below the limit of quantification of the bioanalytical assay (10 pg/mL) at 30 minutes following topical ocular administration of tafluprost 0.0015% ophthalmic solution.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise patients to read the FDA-approved patient labeling (Patient Information and Instructions for Use). Potential for Pigmentation Advise patients about the potential for increased brown pigmentation of the iris, which may be permanent. Also inform patients about the possibility of eyelid skin darkening, which may be reversible after discontinuation of ZIOPTAN.
Potential for Eyelash Changes Inform patients of the possibility of eyelash and vellus hair changes in the treated eye during treatment with ZIOPTAN. These changes may result in a disparity between eyes in length, thickness, pigmentation, number of eyelashes or vellus hairs, and/or direction of eyelash growth. Eyelash changes are usually reversible upon discontinuation of treatment.
Once Nightly Application Advise patients to not exceed once daily dosing since more frequent administration may decrease the intraocular pressure lowering effect of ZIOPTAN. Handling the Single-Dose Container Advise patients that ZIOPTAN is a sterile solution that does not contain a preservative. The solution from one single-dose container is to be used immediately after opening for administration to one or both eyes.
Since sterility cannot be maintained after the single-dose container is opened, discard the open container and remaining contents immediately after administration. Open a new single-dose container every time you use ZIOPTAN. When to Seek Physician Advice Advise patients that if they develop a new ocular condition (e.g., trauma or infection), experience a sudden decrease in visual acuity, have ocular surgery, or develop any ocular reactions, particularly conjunctivitis and eyelid reactions, they should immediately seek their physician's advice concerning the continued use of ZIOPTAN.
Use with Other Ophthalmic Drugs Advise patients if more than one topical ophthalmic drug is being used, the drugs should be administered at least five (5) minutes between applications. Storage Information Instruct patients on proper storage of cartons, unopened foil pouches, and opened foil pouches [see How Supplied/Storage and Handling (16) ]. ecommended storage for cartons and unopened foil pouches is to store refrigerated at 2° to 8°C (36° to 46°F). After the pouch is opened, the single-dose containers may be stored in the opened foil pouch for up to 30 days at room temperature 20° to 25°C (68° to 77°F).
Protect from moisture.
