Both are anticonvulsants. Here is how Lyrica and Lamictal compare on class, mechanism, dosing, approval and supply.
LYRICA is indicated for: • Management of neuropathic pain associated with diabetic peripheral neuropathy • Management of postherpetic neuralgia • Adjunctive therapy for the treatment of partial-onset seizures in patients 1 month of age and older • Management of fibromyalgia • Management of neuropathic pain associated with spinal cord injury LYRICA is indicated for: • Neuropathic pain associated with diabetic peripheral neuropathy (DPN) ( 1 ) • Postherpetic neuralgia (PHN) ( 1 ) • Adjunctive therapy for the treatment of partial-onset seizures in patients 1 month of age and older ( 1 ) • Fibromyalgia ( 1 ) • Neuropathic pain associated with spinal cord injury ( 1 )
LAMICTAL is indicated for: Epilepsy—adjunctive therapy in patients aged 2 years and older: • partial-onset seizures. • primary generalized tonic-clonic (PGTC) seizures. • generalized seizures of Lennox-Gastaut syndrome. ( 1.1 ) Epilepsy—monotherapy in patients aged 16 years and older: Conversion to monotherapy in patients with partial-onset seizures who are receiving treatment with carbamazepine, phenytoin, phenobarbital, primidone, or valproate as the single antiepileptic drug. ( 1.1 ) Bipolar disorder: Maintenance treatment of bipolar I disorder to delay the time to occurrence of mood episodes in patients treated for acute mood episodes with standard therapy. ( 1.2 ) Limitations of Use: Treatment of acute manic or mixed episodes is not recommended. Effectiveness of LAMICTAL in the acute treatment of mood episodes has not been established. 1.1 Epilepsy Adjunctive Therapy LAMICTAL is in…
12.1 Mechanism of Action LYRICA (pregabalin) binds with high affinity to the alpha 2 -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 2 -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 …
12.1 Mechanism of Action The precise mechanism(s) by which lamotrigine exerts its anticonvulsant action are unknown. In animal models designed to detect anticonvulsant activity, lamotrigine was effective in preventing seizure spread in the maximum electroshock (MES) and pentylenetetrazol (scMet) tests, and prevented seizures in the visually and electrically evoked after-discharge (EEAD) tests for antiepileptic activity. Lamotrigine also displayed inhibitory properties in the kindling model in rats both during kindling development and in the fully kindled state. The relevance of these models to human epilepsy, however, is not known. One proposed mechanism of action of lamotrigine, the releva…
Which medicine is right for a given person depends on their diagnosis, other conditions, other medicines, kidney and liver function, pregnancy, and cost or reimbursement — none of which this page knows. Two drugs in the same class are not automatically interchangeable. Never start, stop or switch a prescription medicine on the basis of a web page; that decision belongs to you and your clinician or pharmacist.
Class and summary text is written by the Priya Life Science editorial team. Label, mechanism, route, manufacturer and approval data come from the U.S. FDA via the openFDA API; shortage status from the FDA Drug Shortage Database. Approvals, indications and brand names differ between the US, EU/Ireland (EMA/HPRA) and other regions — a drug approved in one may not be approved, or may carry a different name, in another.
