Olandus 5/Olandus 10: Schizophrenia, combination therapy for mania, preventing recurrence in bipolar disorder: ADULT over 18 years: 10 mg daily adjusted to usual range of 5-20 mg daily; doses greater than 10 mg daily adjusted to usual range of 5-20 mg daily; doses greater than 10 mg daily only after reassessment; max. 30 mg daily. Monotherapy for mania: ADULT over 18 years: 15mg daily adjusted to usual range of 5-20 mg daily doses greater than 15 mg only after reassessment max. 20 mg daily.
Olandus ODT 5/Olandus ODT 10: Schizophrenia: Adults: Dose Selection: Oral olanzapine should be administered on a once-a-day schedule without regard to meals, generally beginning with 5 to 10 mg initially, with a target dose of 10 mg/day within several days. Further dosage adjustments, if indicated, should generally occur at intervals of not less than 1 week, since steady state for olanzapine would not be achieved for approximately 1 week in the typical patient.
When dosage adjustments are necessary, dose increments/decrements of 5 mg QD are recommended.
Efficacy in schizophrenia was demonstrated in a dose range of 10 to 15 mg/day in clinical trials. However, doses above 10 mg/day were not demonstrated to be more efficacious than the 10 mg/day dose. An increase to a dose greater than the target dose of 10 mg/day (i.e., to a dose of 15 mg/day or greater) is recommended only after clinical assessment. Olanzapine is not indicated for use in doses above 20 mg/day.
Dosing in Special Populations: The recommended starting dose is 5 mg in patients who are debilitated, who have a predisposition to hypotensive reactions, who otherwise exhibit a combination of factors that may result in slower metabolism of olanzapine (e.g., nonsmoking female patients ≥65 years of age), or who may be more pharmacodynamically sensitive to olanzapine. When indicated, dose escalation should be performed with caution in these patients.
Maintenance Treatment: The effectiveness of oral olanzapine, 10 mg/day to 20 mg/day, in maintaining treatment response in schizophrenic patients who had been stable on olanzapine for approximately 8 weeks and were then followed for relapse has been demonstrated in a placebo-controlled trial. The physician who elects to use olanzapine for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.
Adolescents: Dose Selection: Oral olanzapine should be administered on a once-a-day schedule without regard to meals with a recommended starting dose of 2.5 or 5 mg, with a target dose of 10 mg/day. Efficacy in adolescents with schizophrenia was demonstrated based on a flexible dose range of 2.5 to 20 mg/day in clinical trials, with a mean modal dose of 12.5 mg/day (mean dose of 11.1 mg/day). When dosage adjustments are necessary, dose increments/decrements of 2.5 or 5 mg are recommended.
The safety and effectiveness of doses above 20 mg/day have not been evaluated in clinical trials.
Maintenance Treatment: The efficacy of olanzapine for the maintenance treatment of schizophrenia in the adolescent population has not been systematically evaluated; however, maintenance efficacy can be extrapolated from adult data along with comparisons of olanzapine pharmacokinetic parameters in adult and adolescent patients. Thus, it is generally recommended that responding patients be continued beyond the acute response, but at the lowest dose needed to maintain remission. Patients should be periodically reassessed to determine the need for maintenance treatment.
Bipolar I Disorder (Manic or Mixed Episodes): Adults: Dose Selection for Monotherapy: Oral olanzapine should be administered on a once-a-day schedule without regard to meals, generally beginning with 10 or 15 mg. Dosage adjustments, if indicated, should generally occur at intervals of not less than 24 hours, reflecting the procedures in the placebo-controlled trials. When dosage adjustments are necessary, dose increments/decrements of 5 mg QD are recommended. Short-term (3-4 weeks) antimanic efficacy was demonstrated in a dose range of 5 mg to 20 mg/day in clinical trials. The safety of doses above 20 mg/day has not been evaluated in clinical trials.
Maintenance Monotherapy: The benefit of maintaining bipolar I patients on monotherapy with oral olanzapine at a dose of 5 to 20 mg/day, after achieving a responder status for an average duration of 2 weeks, was demonstrated in a controlled trial. The physician who elects to use olanzapine for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.
Dose Selection for Adjunctive Treatment: When administered as adjunctive treatment to lithium or valproate, oral olanzapine dosing should generally begin with 10 mg once-a-day without regard to meals.
Antimanic efficacy was demonstrated in a dose range of 5 mg to 20 mg/day in clinical trials.
The safety of doses above 20 mg/day has not been evaluated in clinical trials.
Adolescents: Dose Selection: Oral olanzapine should be administered on a once-a-day schedule without regard to meals with a recommended starting dose of 2.5 or 5 mg, with a target dose of 10 mg/day. Efficacy in adolescents with bipolar I disorder (manic or mixed episodes) was demonstrated based on a flexible dose range of 2.5 to 20 mg/day in clinical trials, with a mean modal dose of 10.7 mg/day (mean dose of 8.9 mg/day). When dosage adjustments are necessary, dose increments/decrements of 2.5 or 5 mg are recommended.
The safety and effectiveness of doses above 20 mg/day have not been evaluated in clinical trials.
Maintenance Treatment: The efficacy of olanzapine for the maintenance treatment of bipolar I disorder in the adolescent population has not been evaluated; however, maintenance efficacy can be extrapolated from adult data along with comparisons of olanzapine pharmacokinetic parameters in adult and adolescent patients. Thus, it is generally recommended that responding patients be continued beyond the acute response, but at the lowest dose needed to maintain remission. Patients should be periodically reassessed to determine the need for maintenance treatment.
Olandus ODT 15: Olanzapine orally disintegrating tablets should be placed in the mouth and allowed to completely dissolve before swallowing the saliva. A glass of water may be taken following administration to assist with swallowing the saliva. Alternatively, the Olanzapine ODT may be dispersed in a full glass of water immediately before administration.
Schizophrenia and Related Disorders: The recommended starting dose for Olanzapine orally disintegrating tablets is 5-10 mg/day, administered as a single daily dose without regard to meals. Daily dosage may subsequently be adjusted on the basis of individual clinical status within the range of 5-20 mg daily. An increase to a dose greater than the routine therapeutic dose of 10 mg/day is recommended only after appropriate clinical reassessment.
Acute Mania Associated with Bipolar Disorder: The recommended starting dose for Olanzapine orally disintegrating tablets is 10 or 15 mg administered once a day as monotherapy or 10 mg administered once daily in combination therapy with lithium or valproate. It may be given without regard to meals. Dosage adjustments, if indicated, should generally occur at intervals of not less than 24 hours. When dosage adjustments are necessary, dose increments/decrements of 5 mg daily are recommended. Antimanic efficacy was demonstrated in a dose range of 5 mg to 20 mg/day in clinical trials. The safety of doses above 20 mg/day has not been evaluated in clinical trials.
Preventing Recurrence in Bipolar Disorder: Patients who have been receiving Olanzapine for the treatment of acute mania should initially continue therapy for preventing recurrence in bipolar disorder at the same dose. For patients already in remission, the suggested starting dose for Olanzapine orally disintegrating tablets is 10 mg once a day. Subsequent daily dosage should be adjusted on the basis of clinical status within a range of 5 mg to 20 mg per day. Olanzapine ODT may be given without regard to meals, as its absorption is not affected by food.
Children: The safety and efficacy of Olanzapine have not been established in patients under 18 years of age.
Elderly patients: A low starting dose of 5 mg/day should be considered for those patients 65 and over when clinical factors warrant.
Patients with hepatic and/or renal impairment: Small single-dose clinical pharmacology studies did not reveal any major alterations in Olanzapine pharmacokinetics in subjects with renal or hepatic impairment. However, as clinical experience is limited in these patients, a lower starting dose (5 mg/day) should be considered. Further dose adjustments, when indicated, should be conservative in these patients.
Female compared with male patients: The starting dose and dose range need not be routinely altered for female patients relative to male patients.
Non-smoking patients compared with smoking patients: The starting dose and dose range need not be routinely altered for non-smoking patients relative to smoking patients.
When more than one factor is present which might result in slower metabolism (female gender, geriatric age, non-smoking status), consideration should be given to decreasing the starting dose. Dose escalation, when indicated, should be conservative in such patients.
