Lumateperone (Caplyta)

Available on Amazon:  Cafer's Mood Stabilizers and Antiepileptic Drugs Lumateperone (CAPLYTA) Pronunciation: luma TEP er ohn / cap LIE ta  “’Lum inated Cap lighter” Antipsychotics are represented  with spooky mascots. Year of US release: 2020 ❖ Antipsychotic (SGA) ❖ D2 antagonist - ⇩DA ❖ 5-HT2A antagonist - ⇧DA ❖ Glutamate modulator FDA-approved for:  ❖ Schizophrenia Lumateperone is a new antipsychotic that purportedly modulates glutamate in addition to the usual SGA mechanism of blocking D2 and 5-HT2A receptors. However, the official prescribing information does not mention glutamate, suggesting the FDA saw insufficient evidence for lumateperone being a first-in-class novel antipsychotic. It appears to be equally effective as risperidone (Risperdal) with fewer side effects other than sedation (Citrome, 2016). Lumateperone’s D2 receptor occupancy is lower than most other antipsychotics. This means extrapyramidal side effects are unlikely. The other antipsychotics with

Levetiracetam (Keppra)

Excerpt from  Cafer's Mood Stabilizers and Antiepileptics Levetiracetam (KEPPRA)   Pronunciation: LEE ve tye RA se tam / KEP ruh “Levitate Keeper”   ❖ Antiepileptic  ❖ Inhibitor of glutamate release FDA approved for: ❖ Focal seizures (adjunct)  ❖ Juvenile myoclonic epilepsy (adjunct)  ❖ Bilateral tonic-clonic seizures (adjunct) Used off label for:  ❖ Other types of seizures Levetiracetam entered the U.S. market in 2000 as an AED with a novel mechanism of action. It binds SV2A, a synaptic vesicle glycoprotein. This reduces the release of glutamate, the brain’s principal excitatory neurotransmitter, thereby preventing hypersynchronization of epileptiform burst firing. Levetiracetam has become one of the most prescribed medications for the treatment of epilepsy. It is not prescribed by psychiatrists . Advantages of levetiracetam as an AED include efficacy for a broad-spectrum of seizure types, lack of cognitive impairment , and  lack of drug interactions . It can be started at an e

It is unrelated to other antiseizure medications.  Zonegran can cause weight loss: Zonisamide decreases appetite and has been shown to decrease binge-eating. Cognitive impairment including “ brain fog ”, confusion, difficulty concentrating, and word-finding difficulty are relatively common. It is not used as a moo
