Efficacy of adjunctive pregabalin in patients taking gabapentin has not been evaluated in controlled trials; consequently, no dosing recommendations can be made when pregabalin is used with gabapentin. The primary efficacy endpoint of change from baseline to Week 15 in mean pain intensity derived from an point numeric rating scale showed numerically greater improvement for the pregabalin-treated patients compared to placebo-treated patients, but did not reach statistical ificance.
Peripheral edema may occur; higher frequencies of weight gain and peripheral edema were observed in patients taking both pregabalin and a thiazolidinedione antidiabetic agent compared to patients taking either drug alone; monitor these patients for possible exacerbation of congestive heart failure symptoms when using pregabalin.
Pregabalin may cause dizziness and somnolence; inform patients that pregabalin may impair their ability to perform tasks such as driving or operating machinery; concomitant use of pregabalin with other central nervous system CNS depressants may exacerbate these effects; for patients 1 month to less than 4 years of age, somnolence includes related terms lethargy, sluggishness, and hypersomnia. Weight gain may occur; long-term cardiovascular effects of pregabalin-associated weight gain are unknown.
Symptoms including, insomnia, nausea, headache, anxiety, and diarrhea were reported following abrupt or rapid discontinuation of treatment; increased seizure frequency may occur in patients with seizure disorders and have rapid discontinued treatment; taper pregabalin gradually over a minimum of 1 week rather than discontinuing the drug abruptly. Unexpectedly high incidence of hemangiosarcoma was identified in 2 different strains of mice; the clinical ificance of this finding is unknown. In controlled studies, blurred vision and other vision-related events were reported with treatment; clinical ificance of the ophthalmologic findings is unknown, inform patients to notify their physician if changes in vision occur; if visual disturbance persists, consider further assessment.
Creatine kinase elevations has been associated with treatment; monitor for symptoms eg, unexplained muscle pain, tenderness, or weakness, particularly if these muscle symptoms are accompanied by malaise or fever ; discontinue treatment if myopathy is diagnosed or suspected or if markedly elevated creatine kinase levels occur. Pregabalin lyrica 50 mg, life-threatening, or fatal respiratory depression reported when coadministered with central nervous system depressants, including opioids, or in the setting of underlying respiratory impairment; consider initiating therapy at low dose and monitor for symptoms of respiratory depression and sedation if co-prescribing of another CNS depressant, like opioid, or prescribing to patients with underlying respiratory impairment.
Based on animal studies, there is a potential risk of tumorigenicity with pregabalin exposure via breast milk to the breastfed infant.
Available clinical study data in patients greater than 12 years of age do not provide a clear conclusion about the potential risk of tumorigenicity with pregabalin. Because of the potential risk of tumorigenicity, breastfeeding is not recommended during treatment. Precise mechanism of action unknown but is a GABA analogue that binds to a subunit of voltage-gated calcium channels in CNS; does not affect sodium channels, opiate receptors, or cyclo-oxygenase enzyme activity; interactions with descending noradrenergic and serotonergic pathways originating from the brain stem appear to reduce neuropathic pain transmission from spinal cord.
Although there are no data in humans, pregabalin has been shown to cross the blood brain barrier in mice, rats, and monkeys.
