Perospirone (Lullan) is an atypical antipsychotic of the azapirone family.[1] It was introduced in Japan by Dainippon Sumitomo Pharma in 2001 for the treatment of schizophrenia and acute cases of bipolar mania.[3][4]

Medical uses[edit]

Its primary uses are in the treatment of schizophrenia and bipolar mania.[3][4]

Schizophrenia[edit]

In a clinical trial that compared it to haloperidol in the treatment of schizophrenia it was found to produce significantly superior overall symptom control.[5] In another clinical trial perospirone was compared with mosapramine and produced a similar reduction in total PANSS score, except with respect to the blunted affect part of the PANSS negative score, in which perospirone produced a significantly greater improvement.[6] In an open-label clinical trial comparing aripiprazole with perospirone there was no significant difference between the two treatments discovered in terms of both efficacy and tolerability.[7] In 2009 a clinical trial found that perospirone produced a similar reduction of PANSS score than risperidone and the extrapyramidal side effects was similar in both frequency and severity between groups.[8]

A meta-analysis published in 2013 found that it is statistically significantly less efficacious than other second-generation antipsychotics.[9]

Adverse effects[edit]

Has a higher incidence of extrapyramidal side effects than the other atypical antipsychotics, but still less than that seen with typical antipsychotics.[1][10] A trend was observed in a clinical trial comparing mosapramine with perospirone that favoured perospirone for producing less prominent extrapyramidal side effects than mosapramine although statistical significant was not reached.[6] It may produce less QT interval prolongation than zotepine, as in one patient who had previously been on zotepine switching to perospirone corrected their prolonged QT interval.[11] It also tended to produce less severe extrapyramidal side effects than haloperidol in a clinical trial comparing the two (although statistical significance was not reached).[5]

Pharmacology[edit]

Perospirone binds to the following receptors with very high affinity (as an antagonist unless otherwise specified):[9][12][13][12][14][15][16]

  • 5-HT1A (partial agonist; Ki=2.9 nM)
  • 5-HT2A (inverse agonist; Ki=1.3 nM)
  • D2 (Ki = 0.6 nM)

And the following receptor with high affinity:[9]

  • H1 (inverse agonist)

And the following with moderate affinity:[9]

And with low affinity for the following receptor:[9]
