Anti manic agents 1- Lithium Class: mood stabilizer Uses: Bipolar disorder MOA: specific mode of action is unknown. It alters chemical changes in the brain and interacts with numbers of neurotransmitters. Theurapeutic range: 0.6-1.2, toxic at 1.5 Adverse effect: Nephrotoxic, hypothyroidism. Patient Teaching: -Normal diet with sodium (do not increase sodium as it can lower lithium level, also do not decrease as lithium already lower sodium). -Report any sign of lithium toxicity -Drink plenty of water to stay hydrated and flush out the lithium. Lithium can get toxic if dehydrated. -Never abruptly stop the drug!! -Interaction: NSAIDS (ibuprofen can damage kidneys and cause lithium toxicity), diuretics (cause dehydration and lithium toxicity), Tricyclic antidepressant (Amitriptyline can cause urinary retention) Lithium toxicity S/S: Tremors, paresthesia, blurred vision, Polyuria, difficulty speaking Contraindication: Renal dysfunction, thyroid disorder, pregnancy, seizures, diabetes, dehydration, heart disease. Nursing consideration: Monitor lithium level (weekly or more frequently at the beginning of treatment), monitor sodium level, monitor BUN (Blood Urea Nitrogen) and creatinine frequently. 2-Valporic Acid: Class: Anticonvulsant mood stabilizer Uses: Bipolar disorder and seizure disorders MOA: inhibit sodium and calcium channels to slow neurons firing and excitability. Also block glutamate (Decreasing CNS excitation). Adverse effect: Thrombocytopenia (increases risk of bleeding) Contraindication: Pregnancy category X (can cause neural tube defect, Liver disease, Thrombocytopenia. Patient teaching: -Report signs of liver toxicity (jaundice, and yellow urine). -Report for abnormal bleeding of the gum, black tarry stool as it can cause thrombocytopenia. -Never abruptly stop the drug!! Nursing consideration: Monitor liver function periodically, Monitor platelets level periodically. 3-Carbamazepine Class: Anticonvulsant mood stabilizer Uses: Bipolar disorder, seizure disorders and neuropathic pain. MOA: inhibit sodium and calcium channels to slow neurons firing and excitability. Also block glutamate (Decreasing CNS excitation) Adverse effect: -Leukopenia (increases risk of infection) Contraindication: Pregnancy category X, Liver disease, Patient teaching: - Report fever and sore throat can be due to leukopenia -Oral contraceptives are ineffective, need alternative mode of contraception. -Never abruptly stop the drug!! Contraindication: Pregnancy category X, Liver disease. Nursing consideration: Monitor liver function labs frequently, Monitor WBC.
