Gabapentin enacarbil
Based on 1 Customer Validation
Gabapentin enacarbil (XP-13512) is a prodrug of Gabapentin (HY-A0057) designed to be absorbed throughout the intestine by high-capacity nutrient transporters. Gabapentin is a potent, orally active P/Q type Ca2+ channel blocker. Gabapentin enacarbil can be used for the study of Restless Legs Syndrome (RLS) and postherpetic neuralgia (PHN).

Biological Activity
Gabapentin enacarbil (XP-13512) demonstrates active apical to basolateral transport across Caco-2 cell monolayers and pH-dependent passive permeability across artificial membranes[1].
Gabapentin enacarbil inhibits uptake of 14C-lactate by human embryonic kidney cells expressing monocarboxylate transporter type-1[1].
Gabapentin enacarbil inhibits uptake of 3H-biotin into Chinese hamster ovary cells overexpressing human sodium-dependent multivitamin transporter (SMVT)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In rats, >95% of an oral dose of 14C-Gabapentin enacarbil is excreted in urine in 24 h as Gabapentin[2].
In monkeys, oral bioavailability of Gabapentin from Gabapentin enacarbil capsules was 84.2%[2].
Compared with intracolonic Gabapentin, intracolonic Gabapentin enacarbil gave a 17-fold higher Gabapentin exposure in rats and 34-fold higher in monkeys[2].
Gabapentin enacarbil may therefore be incorporated into a sustained release formulation to provide extended Gabapentin exposure. Gabapentin enacarbil demonstrates improved Gabapentin bioavailability, increases dose proportionality, and enhances colonic absorption[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (7.59 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (7.59 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
