Risperidone is absolutely ideal for mania. The pharmaceutical industry invested extremely large sums of money in the development of this drug, and its effect is unique. It is the only drug that acts as an antagonist on all types of serotonin and dopamine receptors. Do not use this drug after the attack has subsided, or only use it exclusively during the attack. Definitely not preventively or long-term!!
In the case of depression during hospitalization, SSRIs should definitely not be used . It is a very impractical drug, the onset of action takes 2 weeks, which is a long time. Being in the hospital for a long time is unpleasant for the patient, and it also wastes the insurance company's finances. It is best to use buspirone ; it is much more practical, and the onset of action is immediately after the first dose. Although buspirone is officially intended for anxiety, it also works very well for depression.
Do not administer buspirone after the depressive attack has subsided.
In the case of a hospitalized patient who would very quickly alternate between depressive and manic attacks (if such patients exist), valproate https://www.adcc.sk/web/humanne-lieky/ucinna-latka/kyselina-valproova-5152.html should be used as treatment.
