Isradipine for cognition in sz, NY USA

This is a calcium channel blocker currently approved for hypertension.

The purpose of this study is to evaluate the use of the drug isradipine for cognitive enhancement in patients diagnosed with schizophrenia and schizoaffective disorder. Incomplete treatment response can be common in these disorders. While there are medications that are effective at treating positive symptoms, some other symptoms of the disorders are often left only partially treated (cognitive impairment and negative symptoms). This study will begin to address if the medication isradipine might help to treat some of the cognitive problems associated with schizophrenia and schizoaffective disorder. Isradipine is a medication that acts by blocking a specific type of receptor in the brain called a calcium channel. It is currently approved by the FDA for hypertension.

Our findings revealed a remarkable association between adjunctive raloxifene treatment and the alleviation of verbal memory deficits. Isradipine treatment significantly improved the verbal memory and attention dysfunction in some variables of the Stroop test, compared with the placebo. However, no effect was observed in processing speed and executive function deficits.

To the best of our knowledge, this study provides the first evidence that isradipine is a novel therapy option improving verbal memory and attention, both related to its activity in the hippocampus and the cerebellum. Further investigations are necessary to elucidate the mechanisms of action for both drugs in schizophrenia.
