The mGlu5 receptor: a target for antagonists with improved anxiolytic activity
Summary
Anxiety disorders affect 20% of the total population across the seven major markets. Recent data demonstrates the efficacy of MPEP, the prototypical mGlu5 receptor antagonist as a an anxiolytic. Efficacy was similar compared to that of diazepam but at anxiolytic doses produces less cognitive decline

Anxiety disorders affect 20% of the total population across the seven major markets (see our feature Anxiety Disorders - More Than Just a Comorbidity) and are commonly treated with antidepressants. Adverse effects lead to treatment discontinuation in as many as 16% of patients driving the drug development sector to identify alternative approaches to anxiety. Benzodiazepines are treated cautiously by many physicians for reasons of dependency and withdrawal problems, as well as adverse effects including cognitive impairment. Glutamate (mGlu5) receptor antagonists are being developed as an improved class of anxiolytics and here we highlight the efficacy of MPEP, the prototypical mGlu5 receptor antagonist, which was similar compared to that of diazepam but at anxiolytic doses produces less cognitive decline...[more]
