A 30 year old female, married since one year, presents to the psychiatry clinic with hyperactivity since 2 weeks. A diagnosis of mania is made. She had 3 prior episodes of mania in last 5 years and every time after taking medication she goes to premorbid state. Her urine pregnancy test is positive. Which is the preferred drug for management of this patient?
**Core Concept:** Mania is a symptom of bipolar disorder characterized by elevated mood, increased energy, hyperactivity, and impaired judgment. In bipolar disorder, patients often experience periods of mania interspersed with depressive episodes. The correct drug choice depends on considering the patient's history of prior manic episodes, response to medications, and current pregnancy status.
**Why the Correct Answer is Right:** The correct answer is D - Lithium. Lithium has been the gold standard for the treatment of bipolar disorder, including manic episodes, for decades. It is effective in preventing relapse and maintaining remission, and has been shown to reduce the frequency and severity of both manic and depressive episodes. Given that the patient has a history of positive response to lithium in her past episodes, this confirms its effectiveness for her condition.
**Why Each Wrong Option is Incorrect:**
A. Risperidone (antipsychotic): Although antipsychotics can be effective in treating manic symptoms, they are less effective in preventing relapse and maintaining remission. Also, they may cause significant extrapyramidal side effects and increase the risk of weight gain, diabetes, and cardiovascular events.
B. Valproate (anticonvulsant): Valproate is a mood stabilizer, but it does not have the track record of lithium in preventing relapse and maintaining remission. Additionally, it may cause significant side effects like weight gain, gastrointestinal issues, and hepatotoxicity.
C. Olanzapine (antipsychotic): Similar to risperidone, olanzapine is less effective in preventing relapse and maintaining remission compared to lithium. It can cause significant extrapyramidal side effects, weight gain, and increased risk of diabetes and cardiovascular events.
D. Lithium: As mentioned before, lithium has been proven effective in preventing relapse and maintaining remission in bipolar disorder patients with a history of positive response to lithium. It is also associated with fewer side effects compared to the other options (risperidone, valproate, and olanzapine).
**Clinical Pearl:** Lithium is a safe and effective option for treating bipolar disorder, especially in patients with a positive response history. It has a better safety profile compared to the other antipsychotics (risperidone, valproate, and olanzapine) due to its proven efficacy in preventing relapse and maintaining remission, and fewer side effects.
