Pregabalin is described chemically as (S)-3-(aminomethyl)-5-methylhexanoic acid. The molecular formula is C8H17NO2 and the molecular weight is 159.23. The chemical structure of pregabalin is:
Pregabalin is a white to off-white, crystalline solid with a pKa1 of 4.2 and a pKa2 of 10.6. It is freely soluble in water and both basic and acidic aqueous solutions. The log of the partition coefficient (n-octanol/0.05M phosphate buffer) at pH 7.4 is – 1.35.
LYRICA (pregabalin) Capsules are administered orally and are supplied as imprinted hard-shell capsules containing 25, 50, 75, 100, 150, 200, 225, and 300 mg of pregabalin, along with lactose monohydrate, cornstarch, and talc as inactive ingredients. The capsule shells contain gelatin and titanium dioxide. In addition, the orange capsule shells contain red iron oxide and the white capsule shells contain sodium lauryl sulfate and colloidal silicon dioxide. Colloidal silicon dioxide is a manufacturing aid that may or may not be present in the capsule shells. The imprinting ink contains shellac, black iron oxide, propylene glycol, and potassium hydroxide.
LYRICA (pregabalin) oral solution, 20 mg/mL, is administered orally and is supplied as a clear, colorless solution contained in a 16 fluid ounce white HDPE bottle with a polyethylene-lined closure. The oral solution contains 20 mg/mL of pregabalin, along with methylparaben, propylparaben, monobasic sodium phosphate anhydrous, dibasic sodium phosphate anhydrous, sucralose, artificial strawberry #11545 and purified water as inactive ingredients.
To treat neuropathic pain associated with diabetic neuropathy and post herpetic neuralgia, the recommended adult starting dose of pregabalin is 150 mg per day, given in 2 or 3 divided doses (e.g., 75 mg twice a day or 50 mg 3 times a day).
To treat neuropathic pain associated with the central nervous system, the recommended adult starting dose of pregabalin is 150 mg per day, given in 2 divided doses (e.g., 75 mg twice a day).
To treat pain associated with fibromyalgia, the recommended adult starting dose of pregabalin is 150 mg per day, given in 2 divided doses (e.g., 75 mg twice a day).
After one week of treatment, your doctor may increase the dose of pregabalin to 300 mg per day, given in 2 divided doses (e.g., 150 mg twice a day). The maximum recommended daily dose of pregabalin is 600 mg.
