The Active Pharmaceutical Ingredient (API) is the pure substance that manufacturers use to create the final medicine.

• Chemical Name: 1-(aminomethyl)cyclohexaneacetic acid.

• Physical Form: A white to off-white crystalline solid.

• Solubility: It is "freely soluble" in water and both acidic and basic solutions, which makes it easy for the body to absorb once it reaches the stomach.

• Stability: Gabapentin API is very stable at room temperature but is bitter to the taste, which is why it is almost always sold in capsule or coated tablet form rather than as an open powder.

• Molecular Weight: Approximately 171.24 g/mol.
