Interactions

Lamotrigine, sold as the brand name Lamictal among others, is a medication used to treat epilepsy and stabilize mood in bipolar disorder.^[2] For epilepsy, this includes focal seizures, tonic-clonic seizures, and seizures in Lennox-Gastaut syndrome.^[2] In bipolar disorder, lamotrigine has not been shown to reliably treat acute depression; but for patients with bipolar disorder who are not currently symptomatic, it appears to be effective in reducing the risk of future episodes of depression.^[3]

Common side effects include nausea, sleepiness, headache, vomiting, trouble with coordination, and rash.^[2] Serious side effects include lack of red blood cells, increased risk of suicide, Stevens–Johnson syndrome, and allergic reactions.^[2] Concerns exist that use during pregnancy or breastfeeding may result in harm.^[4] Lamotrigine is a phenyltriazine, making it chemically different from other anticonvulsants.^[2] Its mechanism of action is not clear, but it appears to inhibit release of excitatory neurotransmitters via voltage-sensitive sodium channels and voltage-gated calcium channels in neurons.^[2]^[5] ^[6]

Lamotrigine was first marketed in the United Kingdom in 1991, and approved for use in the United States in 1994.^[2]^[7] It is on the World Health Organization's List of Essential Medicines.^[8] In 2019, it was the 71st most commonly prescribed medication in the United States, with more than 10Template:Nbspmillion prescriptions.^[9]^[10]

Lamotrigine is a member of the sodium channel blocking class of antiepileptic drugs.[67] This may suppress the release of glutamate and aspartate, two dominant excitatory neurotransmitters in the central nervous system.[68] It is generally accepted to be a member of the sodium channel blocking class of antiepileptic drugs,[69] but it could have additional actions, since it has a broader spectrum of action than other sodium channel antiepileptic drugs such as phenytoin and is effective in the treatment of the depressed phase of bipolar disorder, whereas other sodium channel-blocking antiepileptic drugs are not, possibly on account of its sigma receptor activity. In addition, lamotrigine shares few side effects with other, unrelated anticonvulsants known to inhibit sodium channels, which further emphasizes its unique properties.[70]

Subjective effects

This subjective effects section is a stub.

As such, it is still in progress and may contain incomplete or wrong information.

You can help by expanding or correcting it.

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWiki contributors. As a result, they should be viewed with a healthy degree of skepticism.

It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.
