Animal experiment: |
Rats: Thirty minutes before being placed in the startle apparatus, rats are treated with saline (s.c.), MDL-100,151 (1.0 mg/kg s.c.), or one of three doses of ACP-103 (1.0, 3.0, or 10.0 mg/kg s.c.). Five minutes after the pretreatment, rats are administered either DOI HCl (0.5 mg/kg s.c.) or 0.9% saline (s.c.). The acoustic startle session lasted approximately 37 min. After 1 week, rats are tested again in the same acoustic/tactile startle session in the exact order and at the same time as the previous week. The same pretreatment drug or vehicle is administered, and rats are crossed over to receive the treatment opposite to that they received the previous week (e.g., DOI HCl for week 1, 0.9% saline for week 2)[1]. Mice: Non-Swiss albino mice are used for locomotor activity experiments. For determination of spontaneous activity, ACP-103 is administered alone (s.c. 60 min before session start or p.o. 60 min before session start). For hyperactivity experiments, mice are treated with 0.3 mg/kg MK-801 (i.p.) 15 min presession (the peak dose for producing hyperactivity in an inverted-U dose-effect curve as determined in pilot experiments) in combination with vehicle or ACP-103. Motor activity data are collected during a 15-min session in a lit room[1] |

Pimavanserin is an inverse agonist of the serotonin (5-HT) receptor subtype 5-HT2A (IC50 = 1.86 nM; Ki = 0.5 nM).1 It is selective for 5-HT2A over a panel of 65 ion channels, enzymes, and receptors (Kis = >100 nM). Pimavanserin reduces head-twitch behavior and prepulse inhibition deficits induced by the 5-HT2A receptor agonist DOI in rats at doses of 3 mg/kg, p.o. and 1-10 mg/kg, s.c., respectively. It also exhibits antipsychotic-like activity, reducing hyperactivity induced by (+)-MK-801 in mice. Pimavanserin acts synergistically with haloperidol or risperidone to suppress (+)-MK-801-induced hyperactivity and attenuates haloperidol- and risperidone-induced catalepsy in rats.2 Formulations containing pimavanserin have been used for the treatment of psychosis in Parkinson's disease.3

Spotlight on Pimavanserin tartrate and Its Therapeutic Potential in the Treatment of Major Depressive Disorder: The Evidence to Date
Drug Des Devel Ther 2021 Jan 13;15:151-157.PMID:33469267DOI:10.2147/DDDT.S240862.
Major depressive disorder (MDD) is widely prevalent and one of the leading causes of disability. Treatment outcomes remain suboptimal with 1 in 3 patients with MDD responding inadequately to commonly used antidepressants. Pimavanserin, an atypical antipsychotic that modulates serotonergic neurotransmission by selectively binding to serotonin receptor (2A and 2C) subtypes and without dopaminergic activity, may have the potential as an adjunctive treatment for MDD. In a phase 2 trial (n=203), addition of pimavanserin, as compared to placebo, to stable treatment with antidepressants was associated with greater reduction in 17-item Hamilton Depression Rating Scale score [HAMD, least square means (95% confidence interval) of -1.7 (-0.03, -3.37), p=0.039]. Furthermore, treatment with pimavanserin was associated with significantly greater improvement in specific symptoms associated with depression such as impaired sexual function, anxiety, sleepiness, and irritability. However, the availability of pimavanserin for clinical care of patients with MDD remains uncertain. Top-line results of phase 3 studies (n=298) that were announced by the sponsor found similar reductions in HAMD (mean baseline-to-week-5 reduction of 9.0 and 8.1, p=0.296) and rates of adverse events (58.1% and 54.7%) with addition of pimavanserin and placebo respectively to stable treatment with antidepressants. Given the potential benefit for specific symptoms such as impaired sexual function, anxiety and sleep/wakefulness disturbances, future studies that enrich for these symptoms may be needed to clarify the utility of adjunctive pimavanserin in treatment of patients with MDD.
Pimavanserin tartrate: a 5-HT2A inverse agonist with potential for treating various neuropsychiatric disorders
Expert Opin Pharmacother 2008 Dec;9(18):3251-9.PMID:19040345DOI:10.1517/14656560802532707.
Background: Pimavanserin tartrate is the first 5-HT(2A) inverse agonist to enter clinical trials as a treatment for L-dopa-induced psychosis in Parkinson's disease and for augmentation of low-dose risperidone treatment in schizophrenia. Pimavanserin is also being evaluated as a possible anti-insomnia drug. Objective: To discuss the potential of pimavanserin to fill multiple therapeutic needs. Methods: The problems with currently approved antipsychotics and sleep agents are explored to highlight how pimavanserin might address some longstanding issues in the treatment of psychosis and insomnia. Results/conclusions: In Phase II clinical trials, pimavanserin seemed to be safe, well-tolerated and efficacious in treating L-dopa-induced psychosis without worsening motor symptoms. Pimavanserin also potentiated the therapeutic effects of low-dose risperidone, reduced haloperidol-induced akathisia, and increased slow-wave sleep in older individuals.
