Medication mascots and conversion tables for all of the risperidone, paliperidone, and aripiprazole LAIs

Updated: Apr 14

Aristada, Asimtufii, Consta, Hafyera, Initio, Maintena, Perseris, Rykindo, Sustenna, Trinza, Uzedy—which are which?


Here are my medication mascots for aripiprazole, risperidone, and paliperidone. Association of a drug with a mascot is a visual mnemonic technique that enables recollection of many associated facts—in this case, whether the long-acting injectable (LAI) antipsychotic an aripiprazole, risperidone or paliperidone product.


This is the same memory technique used in Cafer's Psychopharmacology: Visualize to Memorize 270 Medication Mascots to distinguish the amphetamines from the methylphenidates. Amphetamine products include an amplifier while those representing methylphenidate products include a Scantron sheet ("Write-a-line" on "Math final date").


Here are the 3 principal mascots for risperidone, paliperidone, and aripiprazole. Antipsychotics are generally represented by spooky characters. They're cringeworthy but effective, at least for me.


Risperdal risperidone mnemonic

Invega Paliperidone mnemonic

Abilify aripiprazole mnemonic

After memorizing the 3 main mascots, learn the following pictures and you will know whether, e.g., Uzedy, is an aripiprazole, risperidone or paliperidone product.


Risperidone long-acting injectable (LAI) products:

  1. Consta

  2. Rykindo

  3. Perseris

  4. Uzedy

  5. Risvan

risperdal consta mnemonic

Rykindo mnemonic

Perseris mnemonic

Uzedy mnemonic


Paliperidone palmitate LAI products:

  1. Sustenna

  2. Trinza

  3. Hafyera

Invega Sustenna Trinza Hafyera mnemonics

Aripiprazole LAI products:

  1. Maintena

  2. Asimtufii

  3. Aristada

  4. Initio

Abilify Maintena mnemonic

Abilify Asimtufii mnemonic

Aristada Initio mnemonic

I had trouble with the spelling of Maintena and Sustenna concerning one vs two N's. Is it Maintena or Maintenna? Sustena or Sustenna? The correct spelling for each is 8 letters: MAIN-TENA and SUST-ENNA.


In Cafer's Psychopharmacology: Visualize to Memorize 270 Medication Mascots, the LAI antipsychotic comparison tables are located on the last page of the green-tabbed sections— Green for antipsychotics, because hallucinations and delusions of "little green men" are signs of psychosis.
