Pimavanserin (Nuplazid™) is a selective and potent serotonin 2A (5-HT2A) receptor inverse agonist and antagonist developed by ACADIA Pharmaceuticals that has been approved in the US as a treatment for patients with hallucinations and delusions associated with Parkinson's disease psychosis. Up to 60 % of patients with Parkinson's disease may develop Parkinson's disease psychosis, which is associated with increased morbidity and mortality and has few treatment options. This article summarizes the milestones in the development of pimavanserin leading to this first approval for the treatment of hallucinations and delusions in patients with Parkinson's disease psychosis.

Pain from renal colic is often severe and incapacitating. Many patients require emergent hospitalization and aggressive analgesia to relieve such discomfort. ⋯ One of the mainstays of therapy for acute renal colic is with non-steroidal anti-inflammatory drugs (NSAIDs). This paper reviews the mechanism by which NSAIDs allow pain relief in renal colic, the evidence for their use in this condition, and the use of NSAIDs combined with other agents in renal colic.

Sugammadex (Bridion(®)) is a modified γ-cyclodextrin that reverses the effect of the steroidal nondepolarizing neuromuscular blocking agents rocuronium and vecuronium. Intravenous sugammadex resulted in rapid, predictable recovery from moderate and deep neuromuscular blockade in patients undergoing surgery who received rocuronium or vecuronium. Recovery from moderate neuromuscular blockade was significantly faster with sugammadex 2 mg/kg than with neostigmine, and recovery from deep neuromuscular blockade was significantly faster with sugammadex 4 mg/kg than with neostigmine or spontaneous recovery. ⋯ Sugammadex also demonstrated efficacy in various special patient populations, including patients with pulmonary disease, cardiac disease, hepatic dysfunction or myasthenia gravis and morbidly obese patients. Intravenous sugammadex was generally well tolerated. In conclusion, sugammadex is an important option for the rapid reversal of rocuronium- or vecuronium-induced neuromuscular blockade.
