Overview
What is Lyrica CR?
LYRICA CR (pregabalin extended-release) tablets are for oral use and contain pregabalin. Pregabalin is described chemically as ()-3-(aminomethyl)-5-methylhexanoic acid. The molecular formula is CHNO and the molecular weight is 159.23. The chemical structure of pregabalin is:
Pregabalin is a white to off-white, crystalline solid with a pK of 4.2 and a pK 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 CR extended-release tablets are administered orally and contain 82.5, 165, or 330 mg of pregabalin, along with Kollidon SR (polyvinyl acetate, povidone, sodium lauryl sulphate, and silica), crospovidone, polyethylene oxide, carbomer, magnesium stearate, polyvinyl alcohol, titanium dioxide, talc, polyethylene glycol, and colorants as inactive ingredients.

What should I talk to my health care provider before I take Lyrica CR?
How should I use Lyrica CR?
LYRICA CR is indicated for the management of:
Efficacy of LYRICA CR has not been established for the management of fibromyalgia or as adjunctive therapy for adult patients with partial onset seizures.
LYRICA CR should be administered once daily after an evening meal.
LYRICA CR should be swallowed whole and should not be split, crushed, or chewed.
When discontinuing LYRICA CR, taper gradually over a minimum of 1 week.
Instruct patients that if they miss taking their dose of LYRICA CR after an evening meal, then they should take their usual dose of LYRICA CR prior to bedtime following a snack. If they miss taking the dose of LYRICA CR prior to bedtime, then they should take their usual dose of LYRICA CR following a morning meal. If they miss taking the dose of LYRICA CR following the morning meal, then they should take their usual dose of LYRICA CR at the usual time that evening following an evening meal .

Clinical Pharmacology
Pregabalin binds with high affinity to the alpha-delta site (an auxiliary subunit of voltage-gated calcium channels) in central nervous system tissues. Although the mechanism of action of pregabalin has not been fully elucidated, results with genetically modified mice and with compounds structurally related to pregabalin (such as gabapentin) suggest that binding to the alpha-delta subunit may be involved in pregabalin's anti-nociceptive and antiseizure effects in animals. In animal models of nerve damage, pregabalin has been shown to reduce calcium-dependent release of pro-nociceptive neurotransmitters in the spinal cord, possibly by disrupting alpha-delta containing-calcium channel trafficking and/or reducing calcium currents. Evidence from other animal models of nerve damage and persistent pain suggest the anti-nociceptive activities of pregabalin may also be mediated through interactions with descending noradrenergic and serotonergic pathways originating from the brainstem that modulate pain transmission in the spinal cord.
While pregabalin is a structural derivative of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA), it does not bind directly to GABA, GABA, or benzodiazepine receptors, does not augment GABA responses in cultured neurons, does not alter rat brain GABA concentration or have acute effects on GABA uptake or degradation. However, in cultured neurons prolonged application of pregabalin increases the density of GABA transporter protein and increases the rate of functional GABA transport. Pregabalin does not block sodium channels, is not active at opiate receptors, and does not alter cyclooxygenase enzyme activity. It is inactive at serotonin and dopamine receptors and does not inhibit dopamine, serotonin, or noradrenaline reuptake.
Non-Clinical Toxicology
LYRICA CR is contraindicated in patients with known hypersensitivity to pregabalin or any of its components. Angioedema and hypersensitivity reactions have occurred in patients receiving pregabalin therapy .
Lithium generally should not be given with diuretics because they reduce its renal clearance and add a high risk of lithium toxicity. Read circulars for lithium preparations before use of such concomitant therapy.
Ethacrynic acid may increase the ototoxic potential of other drugs such as aminoglycoside and some cephalosporin antibiotics. Their concurrent use should be avoided.
A number of drugs, including ethacrynic acid, have been shown to displace warfarin from plasma protein; a reduction in the usual anticoagulant dosage may be required in patients receiving both drugs.
In some patients, the administration of a non-steroidal anti-inflammatory agent can reduce the diuretic, natriuretic, and antihypertensive effects of loop, potassium-sparing and thiazide diuretics. Therefore, when Ethacrynic acid and non-steroidal anti-inflammatory agents are used concomitantly, the patient should be observed closely to determine if the desired effect of the diuretic is obtained.
There have been postmarketing reports of angioedema in patients during initial and chronic treatment with LYRICA. Specific symptoms included swelling of the face, mouth (tongue, lips, and gums), and neck (throat and larynx). There were reports of life-threatening angioedema with respiratory compromise requiring emergency treatment. Discontinue LYRICA CR immediately in patients with these symptoms.
Exercise caution when prescribing LYRICA CR to patients who have had a previous episode of angioedema. In addition, patients who are taking other drugs associated with angioedema (e.g., angiotensin converting enzyme inhibitors [ACE-inhibitors]) may be at increased risk of developing angioedema.
