Lurasidone or Latuda\u00ae <\/sup>is a second-generation antipsychotic, manufactured by Sunovion and introduced in the US in 2010 for the acute treatment of schizophrenia.<\/p>\n

Note:\u00a0This page and its related pages contain the full text of the chapter on lurasidone\u00a0(Latuda) in my book, The Latest Antidepressants. This webpage will always have the most up-to-date version of that chapter.<\/p>\n

1. Acute treatment of schizophrenia (2010)
\n2. Bipolar I depression \u2013 monotherapy

Dosage forms and strengths<\/h4>\n

Tablets: 20 mg, 40 mg, 60 mg, 80 mg, 120 mg<\/p>\n

Please refer to Prescribing Information (see link below) for complete discussion of dosage, administration, warnings and precautions, contraindications, etc.<\/p>\n

I wish we would stop calling them \u201catypical\u201d antipsychotics, for reasons that I have argued in a letter to the editor (Mago, R, Kipnis, D: Atypicals are really typicals now. Psychiatry 2006;3:20-21.)<\/p>\n

The reason lurasidone was\u00a0included in my book on the \u201clatest\u201d antidepressants even though it was introduced in 2010 is because it has more recently been shown to be efficacious for bipolar depression.<\/p>\n

What are the FDA indications for lurasidone?<\/strong><\/p>\n

    \n
  1. Acute treatment of schizophrenia (2010)<\/li>\n
  2. Bipolar I depression \u2013 monotherapy<\/li>\n
  3. Bipolar I depression \u2013 adjunct to lithium or valproate<\/li>\n<\/ol>\n

    Note: no mania study has been done, I think because many antimanic agents already available and bipolar depression was where the \u201cunmet need\u201d was.<\/p>\n

    What is the half-life of lurasidone and why does that matter?\u00a0<\/strong>\u00a0<\/strong><\/p>\n

    Since the half-life of lurasidone is 18 hours, it can be prescribed in once-a-day dosing, which is more convenient and hence better for adherence.<\/p>\n

    Aripiprazole has a half-life of 72 hours, which has pros and cons. If a person develops an adverse effect on aripiprazole, it takes a longer time for the adverse effect to subside, even if the aripiprazole is stopped. On the other hand, I just had a patient who had akathisia on lurasidone. We stopped the lurasidone and the akathisia was markedly better within a day.\u00a0<\/strong><\/p>\n

    Lurasidone must be taken with food<\/strong>\u00a0<\/strong><\/p>\n

    An important thing to remember is that the maximum concentration of lurasidone is reduced by half (i.e., a lot) if it is not taken with food.\u00a0<\/strong><\/p>\n

    The patient may ask: can I take it with a small snack? The answer is that it depends on what your definition of a \u201csmall snack\u201d is! The manufacturer recommends that lurasidone be taken with at least 350 calories of food. Whether that food is high fat or low fat does not matter.<\/p>\n

    What dose of lurasidone should I prescribe?<\/strong><\/p>\n

    The standard recommendation is to start at 40 mg, once a day. However, patients with bipolar depression may be more sensitive to adverse effects than patients with schizophrenia. Therefore, it may be wise to start with 20 mg\/day in patients with bipolar depression. The dose can be gradually increased to a maximum of 160 mg\/day. Note: when lurasidone was initially introduced, the recommended maximum dose was 80 mg\/day; this was later changed to 160 mg\/day.<\/p>\n

    Lurasidone is available in a range of pill sizes: 20 mg, 40 mg, 60 mg, 80 mg, and 120 mg. However, if you start with a 20 mg pill, keep in mind that you can only give the patient a prescription for 30 pills. There are \u201cquantity limitations\u201d on the number of pills the person can get per month. This makes it a bit inconvenient to increase to 40 mg\/day after a few days. Isn\u2019t it better to prescribe 40 mg pills, but ask the patient to start with half pill per day for a certain number of days? Then, if there are no significant side effects, increase to a full pill per day. Now, the pills are not scored, but they can be cut with a pill cutter and the division of the pill doesn\u2019t have to be exact.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
