Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as a prophylactic medication against manic and depressive episodes. Its mechanism of action involves inhibiting inositol monophosphatase, increasing IP3 accumulation through the Gq-PLC-IP3-Ca2+ pathway, impacting monoamines, and reducing arachidonic acid turnover. Despite its effectiveness, lithium has adverse effects such as fine hand tremors, dizziness, xerostomia, GI distress, sedation, and weight gain, especially when combined with antipsychotics. Furthermore, as lithium has a very narrow therapeutic index, lithium toxicity can occur at concentrations above 1.5 mEq/L. Hemodialysis is required for acute toxicity when the concentration is 3 mEq/L or higher.
Antipsychotic drugs like clozapine (Clozaril), olanzapine (Zyprexa), and lurasidone (Latuda) are also used to manage refractory and acute mania individually or as adjunctive therapy. Anticonvulsants such as valproic acid compounds (Depakote) help manage acute mania in pediatric bipolar disorder, while lamotrigine (Lamictal) helps in the maintenance treatment and the prevention of depressive episodes. These drugs, too, have their side effects and require careful administration and monitoring.
Mania is a psychological condition characterized by heightened mood, expanded energy, or irritability, and a reduced need for sleep.
It is a key phase of bipolar disorder, managed with mood stabilizers like lithium, antipsychotics, and anticonvulsants.
Lithium carbonate is the most effective prophylactic medication for bipolar disorder.
Its mechanism involves inhibiting inositol monophosphatase and increasing IP3 accumulation. It also impacts monoamines and decreases arachidonic acid turnover.
However, lithium treatment shows adverse effects like fine hand tremors, dizziness, xerostomia, GI distress, sedation, and weight gain when combined with antipsychotics.
Continuous monitoring of serum lithium levels is vital, as toxicity can occur at concentrations above 1.5 mEq/L, necessitating dialysis.
Antipsychotic drugs like clozapine, olanzapine, and lurasidone help manage refractory and acute mania, either individually or as an adjunct therapy.
Anticonvulsants such as valproic acid compounds, carbamazepine, and lamotrigine help manage pediatric bipolar disorder acute mania and are maintenance treatments for bipolar disorder.
