Overview: Tafluprost vs Latanoprost
| Parameter | Tafluprost | Latanoprost |
|---|---|---|
| Drug Class | Prostaglandin F2α analog | Prostaglandin F2α analog |
| Indication | Open-angle glaucoma, ocular hypertension | Same |
| Molecular Formula | C25H34F2O5 | C26H40O5 |
| Preservative-Free Option | Yes (common in sensitive eyes formulations) | Rare |
| Recommended Concentration | 0.0015% | 0.005% |
| Dosing Frequency | Once daily | Once daily |
| Shelf Life | Up to 36 months | Up to 36 months |

Formulation Considerations
1. Solubility and pH Sensitivity
- Tafluprost is more pH-sensitive and requires careful buffering in ophthalmic formulations.
- Latanoprost is relatively easier to solubilize and stabilize in aqueous media.
2. Preservative-Free Compatibility
- Tafluprost is widely used in preservative-free single-dose units, especially for patients with dry or sensitive eyes.
- Latanoprost is typically preserved with benzalkonium chloride (BAK), which may cause irritation in sensitive users.
3. Impurity Profiles
- Chemignition ensures that both Tafluprost and Latanoprost APIs meet stringent impurity and residual solvent limits.
- Tafluprost has slightly tighter impurity thresholds due to its structure and sensitivity.

FAQs
Which is more effective: Tafluprost or Latanoprost?
Both are highly effective in lowering intraocular pressure. Tafluprost may offer superior results for sensitive eyes and preservative-free needs.
Can I buy both APIs from one supplier?
Yes. Chemignition Laboratory manufactures and exports both Tafluprost and Latanoprost APIs in pharmacopeial grades.
What is the shelf life of Tafluprost API?
Chemignition’s Tafluprost API offers a 36-month stability when stored between -20°C to -10°C.
Which API is easier to formulate?
Latanoprost is slightly more formulation-friendly in multi-dose systems, while Tafluprost needs more controlled pH handling.
Do both APIs come with COA and MSDS?
Yes. Chemignition provides COA, MSDS, and stability data for both APIs.
