[Explanation] This standard for manic episodes is only applicable to the diagnosis of a single episode.

20.2 Mania without psychotic symptoms [F30.1]

Treatment of manic episodes

Manic episode medication

1.lithium carbonate

(1) Indications and contraindications: It is currently the drug of choice for the treatment of manic episodes. It is mainly used for acute episodes of mania and to prevent the recurrence of mania or depression in patients with two-way affective disorder. The total effective rate is more than 80%. Patients with acute and chronic nephritis, renal insufficiency, severe cardiovascular disease and central nervous system organic disease with acute infection, electrolyte disturbance, and low-salt diet are contraindicated. Use with caution in elderly frail, pregnant and lactating women, and children under 12 years of age.

(2) Usage and dosage: Oral is the only route of administration. Generally, 0.25 is given 3 times a day, and the dose is increased every 1-2 days, and the therapeutic dose is 1.5-2.0 g per day within 7-10 days. Take in divided doses. Lithium salt treatment is generally effective within 7-10 days. After the blood lithium concentration reaches 2-4 weeks after treatment, the condition does not improve, and other treatments should be replaced.

The poisoning dose of lithium salt is close to the treatment dose, and its efficacy and adverse reactions are closely related to the blood lithium concentration. In addition to closely monitoring the disease changes and treatment response during the treatment, the blood lithium concentration should be monitored. The dose can be adjusted accordingly to determine the presence of No poisoning and degree of poisoning. Measured once a week at the beginning of treatment, and thereafter 1-2 times every half month or one month depending on the dose and treatment response. In neutral acute cases, the lithium concentration should be maintained at 0.6-1.2 ol / L. Above 1.4ol / L, it is prone to poisoning reactions, especially in the elderly and patients with organic diseases. In order to compare the values of lithium concentration in each blood, it is required to determine the blood lithium in each blood sample 12 hours after taking the medicine In advance or more than 12 hours, it can affect the value of blood lithium concentration, thus losing the significance of comparison.

The dosage must be individualized and adjusted according to the patient's age, weight, illness, adverse reactions, and blood lithium concentration. Increasing the dosage should be slow, and the daily dose should be taken in divided doses to reduce the occurrence of adverse reactions. Patients should be treated with salt during treatment. diet. Encourage patients to drink more water and pay attention to the treatment of poisoning reactions.

(3) Maintenance treatment: lithium carbonate maintenance treatment can prevent recurrence. Double-blind experiments have shown that lithium salts can reduce the number of relapses and the severity of emotional illness. The maintenance treatment amount is half of the treatment amount, that is, 0.75-1.0 per day, and the maintenance lithium concentration should not be lower than 0.6ol / L. The course of treatment is at least 1 year.

(4) Adverse reactions: Adverse reactions of lithium carbonate are positively correlated with blood lithium concentration. Usually occurs 1-2 weeks after taking the drug, and some appear later. Adverse reactions such as the digestive system, nervous system, urinary system, cardiovascular system, hematopoietic system, endocrine system and lithium poisoning can be completely eliminated after reduction and withdrawal.

2. Other drugs

(1) Antiepileptic drugs: represented by carbamazepine, a second-line antimanic drug commonly used in clinical practice, which is suitable for patients who have failed to treat with lithium carbonate. In addition, valproate is also a common antimanic drug, especially for patients who are ineffective, intolerant, and rapidly circulating bipolar mania.

(2) Antipsychotics: chlorpromazine and haloperidol can control manic episodes faster and better, but they are generally not used alone and are often used in combination with lithium carbonate.

(3) Other drugs: such as clonazepam, clonidine, and verapamil. Although studies have found that such drugs are effective, the efficacy of treatment is not as good as lithium salts, carbamazepine, and sodium valproate *.

Manic episode (2) electroconvulsive therapy

Electroconvulsive therapy has a certain therapeutic effect on severe mania, and its mechanism of action may be the same as that of drugs, that is, to correct the metabolic abnormalities of central neurotransmitters. In the case of intensive monitoring measures, drug treatment can be applied alone or in combination. If concomitant drug treatment, the dose should be reduced.
