Some Tricyclic Antidepressants and Their Recommended Dosage

Mipramine HCI:

  • Usual initial adult dose for outpatients is 75 mg/day increased to 150 mg/day. Doses over 200 mg/day are not recommended. Maintenance dose is 50 to 150 mg/day.
  • For hospitalized patients, usual initial adult dosage is 100 mg/day in divided doses gradually increased to 200 mg/day as required. If no response occurs after 2 weeks, increase dose to 250 to 300 mg/day.
  • For adolescents and elderly patients, usual initial dose is 30 to 40 mg/day, not to exceed 100 mg/day.
  • Childhood bed wetting - An oral dosage of 25 mg/day given 1 hour before bedtime should be tried in children 6 years of age and older.
  • If satisfactory response does not occur within 1 week, increase the dose to 50 mg nightly in children younger than 12 years of age; children older than 12 may receive up to 75 mg nightly.
  • Doses larger than 75 mg do not work better and tend to incense the side effects.

Imipramine HCI (cant.):

  • Consider instituting a drug-free period following an adequate therapeutic trial with a favorable response.
  • To reduce the tendency to relapse, taper dosage gradually rather than discontinue abruptly.

Imipramine pamaate:

  • Initiate adult dose for outpatients at 75 mg/day and increase to 150 mg/day, which is the dose level at which optimum response is usually obtained. If necessary, dose may be increased to 200 mg/day. Doses higher than 75 mg/day may also be administered on a once-a­day basis at bedtime after the optimum dosage and tolerance have been determined.
  • Maintenance dosage is usually 75 to 150 mg/day administered on a once-a-day basis, preferably at bedtime.

Nortriptyline:

  • Usual adult dosage is 25 mg 3 to 4 times daily. As an alternative regimen, the total daily dose may be given once a day.
  • Doses above 150 mg/day per day are not recommended.
  • Usual dosage in elderly patients is 30 to 50 mg/day in divided doses.

Protriptyline:

  • Usual adult dosage is 15 to 40 mg/day divided into 3 or 4 doses. If necessary, dose may be increased to 60 mg/day. Make dose increases with the morning dose.
  • Doses above 60 mg/day are not recommended.
  • For elderly patients, the usual dosage is 5 mg 3 times a day initially and is increased gradually. The cardiovascular system must be monitored closely if the daily dose exceeds 20 mg.

Trimipramine:

  • Usual initial adult dosage for outpatients is 75 mg/day in divided doses. May be increased to 150 mg/day if needed.
  • Doses over 200 mg/day are not recommended.
  • Hospitalized patients may be given 100 mg/day initially in divided doses, increased gradually in a few days to 200 mg/day. If improvement does not occur in 2 to 3 weeks, the dose may be increased to the maxi­mum recommended dose of 250 to 300 mg/day.
  • Usual initial dose for adolescents and elderly patients is 50 mg/day, increasing in gradual increments up to 100 mg/day.

Tricyclic Antidepressants - Uses and Precautions

Type of drug:

Antidepressants; mood-elevating agents.

How the Drug Works:

Tricyclic antidepressants (TCAs) appear to adjust or rebalance the brain’s own natural chemicals (neurotransmitters), which control mood, feelings, and behaviors. The effect may take a few weeks (1 to 4) to be noticed.

Uses:

For the relief of symptoms of depression (except clomipramine).

Clomipramine: Only for the treatment of obsessive-compulsive disorder.

Doxepin: To treat anxiety.

Imipramine: For the treatment of bedwetting in children 6 years of age and older after possible organic causes have been excluded by appropriate tests.

Unlabeled Uses: Occasionally doctors may prescribe doxepin, clomipramine, imipramine, or amitriptyline to control chronic pain and to treat bulimia. Imipramine, clomipramine, nortriptyline, and other tricyclic anti­depressants have also been used to treat panic disorder. Amitriptyline has been used to prevent the onset of cluster and migraine headaches and to treat pathologic weeping and laughing secondary to forebrain disease. Protriptyline has been used in the treatment of obstructive sleep apnea. Trimipramine and doxepin have been studied in the treatment of peptic ulcer disease and to treat skin disorders. Desipramine has been used to facilitate cocaine withdrawal and to treat bulimia. Clomipramine and nortriptyline have been used to treat panic disorder. Nortriptyline has also been used to treat skin disorders and premenstrual depression.

Precautions:

Tardive Dyskinesia: Involuntary and uncontrollable movements may develop in patients treated with these drugs. Occurrence is highest among the elderly, especially women. The risk of developing these involuntary movements and the likelihood that they will become permanent are increased as the length of treatment and the total amount of drug given increases. However, it is possible to develop these symptoms after short-term treatment at low doses.

Neuroleptic Malignant Syndrome (NMS) Is a potentially fatal syndrome associated with use of tricyclic antidepressants. Symptoms include increased body heat, muscle rigidity, altered mental abilities including catatonia, irregular pulse or irregular blood pressure, increased heart rate, sweating, and irregular heart rhythm.

Withdrawal Symptoms: Stopping abruptly after prolonged therapy may pro­duce nausea, headache, dizziness, nightmares, and malaise. Clomipramine may also cause vomiting, sleep disturbances, hyperthermia (abnormally high temperature), and irritability. Gradual dose reduction may produce, within 2 weeks, transient symptoms including irritability, restlessness, dreams, and sleep disturbances.

Sensitivity to sunlight: May occur. Avoid prolonged exposure to the sun. Use sunscreens and wear protective clothing until tolerance is determined. These drugs may reduce tolerance to hot weather.

Pregnancy: Adequate studies have not been done in pregnant women. Use only if clearly needed and potential benefits outweigh the possible hazards to the fetus. There have been a few reports of birth defects associated with use of imipramine and amitriptyline. Withdrawal symptoms have been seen in newborns of mothers who have taken clomipramine, desipramine, or imipramine until delivery.

Breastfeeding: Tricyclic antidepressants appear in breast milk. Because of the potential for adverse reactions, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother. Consult your doctor before you begin breastfeeding.

Children: Amitriptyline and doxepin are not recommended for patients younger than 12 years of age. Safety and effectiveness have not been established for amoxapine in children younger than 16 years of age. Imipramine HCI use in bed wetting should be limited to children 6 years of age or older. The safety and effectiveness of imipramine HCI in children with conditions other than bed wetting have not been established. Safety and effectiveness have not been established for clomipramine in children younger than 10 years of age. Trimipramine, nortriptyline, desipramine, imipramine pamoate, and protriptyline are not recommended for use in children.

Elderly: Elderly patients are particularly sensitive to the anticholinergic effects (eg, constipation; difficulty urinating; confusion) of tricyclic antideprossants and may be at increased risk for falls. Lower than normal adult doses are generally used when starting therapy.

Dibenzapine Derivatives Drug - How does Dibenzapine Derivatives Works?

Type of Drug:

Atypical antipsychotic.

How the Drug Works:

Atypical anti psychotics act upon several neurotransmitter systems, including antagonism at one or more types of dopamine receptors, antagonism at alphacadrenergic receptors, and activity at muscarinic, histamine H1 , or nicotinic receptors.

Uses:

For the treatment of schizophrenia.

Olanzapine: For the short-term treatment of acute manic episodes associated with Bipolar I disorder.

Precautions:

Tardive dyskinesia: InvOluntary and uncontrollable movements may develop in patients treated with antipsychotic drugs. Occurrence is high­Specially women. However, it is impossible to predict which patients are likely to develop the syndrome. The risk of developing these involuntary movements and the likelihood they will become permanent are increased with long-term use and with high doses. However, it is possible to develop these symptoms after short­term treatment at low doses. The syndrome is characterized by rhythmical, involuntary movements of tongue, face, mouth, or jaw (eg, protrusion of toQue, puffing of cheeks, puckering of mouth, chewing movements), sometimes accompanied by involuntary movements of the arms and legs. Fine worm-like movement of the tongue may be an early sign of the syndrome. If the medication is stopped at this time, the syndrome may not develop further. There is no known treatment for established cases of tardive dyskinexia, although the syndrome may stop, partially or completely, if the drug is Withdrawn. Antipsychotic treatment, however, may suppress or partially suppress the signs and symptoms of the syndrome and thereby possibly mask the underlying disease process. The effect that symptomatic suppression has upon the long-term course of the syndrome is unknown.

Neuroleptic Malignant Syndrome (NMS): Is a potetially fatal syndrome oscillated with antipsychotic drugs. Symptoms Include fever, muscle rigidity, altered mental abilities, irregular pulse and blood pressure, increased heart rate, sweating, and irregular heart rhythm.

Seizures: Seizures have occurred during therapy with some antipsychotic agents. The likelihood of seizure becomes greater at higher doses.

Pregnancy: There are no adequate and well-controlled studies in pregnant women. Use only if clearly needed and the potential benefits out­weigh the possible hazards to the fetus.

Breastfeeding: It is not known if these drugs are excreted in breast milk. Do not use breastfeed while taking one of these drugs.

Children: Safety and effectiveness of loxapine in patients younger than 16 years of age have not been established. Safety and effectiveness of clozapine, olanzapine, and quetiapine have not been established.

Lab Tests: Lab tests will be required to monitor therapy. Tests include blood counts and liver function.

How Does Oxcarbazepine Works?

Type of Drug:

Anticonvulsant; drug used to treat a variety of seizure disorders.

How the Oxcarbazepine Product Works:

Oxcarbazepine prevents or reduces some types of seizures by controlling abnormal nerve impulses in the brain.

Uses of The Oxcarbazepine:

For use alone or in combination therapy for the treatment of partial seizures in adults with epilepsy and as combination therapy for the treatment of partial seizures in children 4 to 16 years of age with epilepsy.

Unlabeled Uses: Oxcarbazepine has been used for atypical panic disorder.

Precautions:

Do not use in the following situations: Allergy to oxcarbazepine or any of its ingredients.

Pregnancy: There are no adequate and well-controlled clinical studies in pregnant women; however, it is closely related structurally to carbamazepine, which is considered to be teratogenic in humans. Use during pregnancy only if clearly needed and the potential benefits to the mother outweigh the possible hazards to the fetus.

Breastfeeding: Oxcarbazepine and its active metabolite MHO are excreted in human breast milk. Because of the potential for serious adverse reactions, decide whether to discontinue nursing or to discontinue the drug in nursing women, taking into account the importance of the drug to the mother.

Children: Oxcarbazepine has been shown to be effective as adjunctive therapy combined with other drugs for partial seizures in patients 4 to 16 years of age.

Lab Tests: Lab tests will be required to monitor therapy. Tests may include blood sodium levels, liver function, kidney function, and blood tests.

Drug Interactions:

Tell your doctor or pharmacist if you are taking or if you are planning to take any over-the-counter or prescription medications or dietary supplements with oxcarbazepine. Doses of one or both drugs may need to be modified or a different drug may need to be prescribed. The following drugs and drug classes interact with oxcarbazepine:

  • Calcium channel blockers (eg, felodipine)
  • Carbamazepine (eg, tegretol)
  • Phenobarbital (eg, solfoton)
  • Phenytoin (eg, dilantin)
  • Valproic acid (eg, depakene)

Side Effects:

Every drug is capable of producing side effects. Many oxcarbazepine users experience no, or minor, side effects. The frequency and severity of side effects depend on many factors including dose, duration of therapy, and individual susceptibility. Possible side effects include:

Digestive Tract: Nausea; vomiting; stomach pain; inflammation of the stomach; appetite changes; dry mouth; toothache; diarrhea; indigestion; constipation; rectal bleeding or pain.

Nervous System: Headache; dizziness; drowsiness; anxiety; fatigue; weak­ness; incoordination; tremors; continual rapid eye movement; abnormal gait; sleeplessness; impaired concentration; amnesia; worsening of seizures; involuntary muscle contractions; unstable emotions; decreased sensation to stimuli; nervousness; agitation; speech disorder; confusion; feeling of whirling motion; abnormal EEG; abnormal thinking.

Respiratory System: Sinus congestion; runny nose; upper respiratory infection; cough; breathing difficulties; sore throat; nosebleed; chest infection.

Skin: Acne; hot flashes; flushing; rash; unusual bruising; increased sweating; itching.

Other: Double vision; abnormal vision; earache; ear infection; fever; allergy; swelling of the legs; chest pain; weight increase; low blood pressure; following down; swollen lymph nodes; viral infection; urinary tract infection; frequent urination; inflammation or pain of the vagina; low blood sodium levels; thirst.

Guidelines for Use:

  • Dosage is individualized. Take exactly as prescribed.
  • Do not stop taking or change the dose unless advised to do so by your doctor.
  • May be taken without regard to meals.
  • Avoid alcohol and other mental depressants (eg, narcotics, tranquilizers, antihistamines) while you are taking this medicine.
  • Treatment should be withdrawn gradually to minimize the potential of increased seizure frequency.
  • If a dose is missed, take it as soon as possible. If several hours have passed or if it is nearing time for the next dose, do not double the dose to catch up, unless advised by your doctor. If more than one dose is missed, or it is necessary to establish a new dosage schedule, contact your doctor or pharmacist.
  • Additional non hormonal forms of contraception (eg, latex condoms) are recommended because of a reduction in hormonal contraceptive efficacy during therapy.
  • Avoid alcohol during therapy; it may cause drowsiness.
  • May cause drowsiness, dizziness, or blurred vision. Use caution while driving or performing hazardous tasks requiring alertness, coordination, or physical dexterity until tolerance is determined.
  • Store at controlled room temperature (59° to 86°F). Keep tightly closed

Valproic Acid and Derivatives Drug Information

Type of Drug:

Anticonvulsant; drug used to treat epilepsy, seizures, and other conditions.

How the Drug Works:

Valproic acid prevents or reduces the number of seizures by controlling the abnormal activity of nerve impulses in the brain and central nervous system. Sodium valproate and divalproex sodium are converted to valproic acid in the body.

Uses:

Used alone or in combination with other anticonvulsants to control simple and complex absence seizures (petit mal).

Used alone or in combination with other anticonvulsants to control isolated complex partial seizures or complex partial seizures associated with other types of seizures.

Delayed-release tablets: To treat manic episodes associated with bipolar disorder.

Delayed-release, extended-release tablets: For the prevention of migraine headaches.

Unlabeled Uses: May be effective as an adjunct to antipsychotic drugs in the symptomatic management of schizophrenia in patients who fail to respond to an adequate trial of the antipsychotic agent alone. Also may be a useful adjunct in schizophrenic patients with EEG abnormalities suggestive of seizure activity, or in those patients with agitated or violent behavior. May be effective in relieving tardive dyskinesia in patient receiving long-term antipsychotic drug therapy. For the treatment of aggressive outbursts in children with attention deficit hyperactivity disorder. Has been shown to be effective in a limited number of nations with organic brain syndrome.

Precautions:

Liver disease: Liver failure resulting in death has occurred in patients receiving valproic acid and its derivatives. Children younger than 2 years of age are at an increased risk of developing fatal liver toxicity, especially if they are taking several anticonvulsant medications or have birth­related metabolic disorders, severe seizure disorders accompanied by mental retardation, or brain damage. Liver problems usually occur during the first 6 months of treatment. Loss of seizure control, general feeling of ill health, weakness, drowsiness, facial swelling, appetite loss, yellowing of skin and eyes, or persistent or unexplained vomiting may be warning signs of possible liver problems.

Pancreatitis: Cases of life-threatening pancreatitis have been reported in children and adults receiving valproate. Pancreatitis can occur at any time while using valproic acid. Abdominal pain, nausea, vomiting, or anorexia can be symptoms of pancreatitis that require prompt medical evaluation.

Pregnancy: Studies have shown a potential risk to the fetus. Using these drugs during pregnancy may result in birth defects. If you are pregnant or are planning to become pregnant, discuss with your doctor the possible risks to the unborn infant. Use only if clearly needed and the potential benefits outweigh the possible risks.

Breastfeeding: Valproic acid appears in breast milk. Consult your doctor before you begin breastfeeding.

Children: Children younger than 2 years of age may be particularly sensitive to the possible liver damage caused by valproic acid, especially if taking other anticonvulsant drugs at the same time. Safety and effectiveness have not been established in children younger than 18 years of age for treatment of acute mania. Safety and efficacy of divalproex sodium for the prevention of migraines has not been established in children younger than 16 years of age. Safety and effectiveness of divalproex sodium extended-release tablets for the prevention of migraine headache and treatment of epilepsy have not been established in children younger than 18 years of age. Sprinkle capsules me for adults and children 10 years of age and older. Consult your doctor See Liver disease.

Elderly: Elderly patients may be at an increased risk of drowsiness and tremor. Lower doses are usually used when starting therapy.

Lab Tests: Lab tests will be required during treatment. Tests may include liver function, blood cell counts, blood-clotting tests, and valproic acid blood levels.
