Absorption, Distribution and Excretion
Perfluorohexyloctane penetrates meibomian glands, where it has been reported to interact with and dissolve the altered, viscous meibum in the glands. A single pharmacokinetic study showed low systemic perfluorohexyloctane blood levels after topical ocular administration. In rabbits, perfluorohexyloctane was detected in tears at six hours and in meibomian glands at 24 hours following ophthalmic administration, with minimal systemic exposure. Metabolism / Metabolites Perfluorohexyloctane was not metabolized by human liver microsomes _in vitro_. |

| Additional Infomation |
Perfluorohexyloctane is a fluoroalkane that is tetradecane in which all of the hydrogen atoms at positions 1, 2, 3, 4, 5, and 6 have been replaced by fluorine atoms. It is an ophthalmic solution used to treat the signs and symptoms of dry eye disease. It has a role as an ophthalmology drug and a nonionic surfactant. It is a fluorohydrocarbon and a fluoroalkane. It derives from a hydride of a tetradecane.
Perfluorohexyloctane is a semifluorinated alkane that contains six perfluorinated carbon atoms and eight hydrogenated carbon atoms. It is an inert, slightly amphiphilic compound. Because it is a completely non-aqueous liquid, microbial growth is not possible; therefore, its drug products do not need to be combined with any preservative. Perfluorohexyloctane has been used in the field of ophthalmology as a vitreous substitute. It was approved by the FDA on May 18, 2023 for the treatment of dry eye disease. Drug Indication Perfluorohexyloctane ophthalmic formulation is indicated for the treatment of the signs and symptoms of dry eye disease. Mechanism of Action Perfluorohexyloctane mediates its actions in the lipid layer and meibomian glands. While the exact mechanism of action is not fully understood, perfluorohexyloctane is believed to interact with the air-liquid interface of the tear film and form a monolayer, preventing the evaporation of the aqueous phase of the tears. Pharmacodynamics Perfluorohexyloctane is administered ophthalmically to alleviate symptoms of dry eye disease, increase tear film breakup time, and increase lipid layer thickness. Having low surface and interface tensions, perfluorohexyloctane spreads rapidly across the ocular surface. It is reported to cause minimal visual disturbances, attributed to its refractive index being similar to that of water. |

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
