Zyprexa is one of the trade names of the drug Olanzapine. This atypical antipsychotic that has been approved by the FDA for treating bipolar disorder and schizophrenia is widely used in most parts of the world. While Olanzapine is similar structurally to clozapine, it is categorized as a thienobenzodiazepine. Formulations of this drug are produced and marketed by Eli Lily and Company (pharmaceutical company). Their patent for the drug expires in 2011. Zyprexa was sold for $2.2bn in the United States in 2008. In combination with fluoxetine, Zyprexa has been known to treat resistant depression. The drug has been approved for treating adolescents (13 to 17 years of age) and in the elderly subject to certain stipulations as detailed in the rest of the article. There has been no approval for using the drug in children below 13 years of age. Zyprexa drug comes in three forms: tablets, disintegrating wafer meant for oral use and as intramuscular injections.
Conditions Treated By Zyprexa
Olanzapine or popularly referred to as Zyprexa is an atypical antipsychotic that has been approved by the FDA for treating bipolar disorder and schizophrenia. Zyprexa has been used for treating schizophrenia and mixed and acute manic episodes of bipolar disorder as well as in the maintenance treatment of bipolar disorder. When combined with fluoxetine, Zyprexa aids in the treatment of acute depressive episodes related to resistant depression especially in adults. The drug has also been approved for treating long term bipolar disorder.
Zyprexa has been considered for treatment of certain anxiety spectrum disorders such as post traumatic stress disorder, panic disorder and generalized anxiety disorder. However, there is neither any proven study to establish this nor a FDA approval for such indications. Some of the other off label conditions that are considered to be treated by this drug includes treating eating disorders like anorexia nervosa as well as certain major depressive disorders that do not have psychotic features. Stuttering and Tourette syndrome are other conditions that Zyprexa supposedly treats. 2.5 to 5 mg of this drug is sometimes prescribed as a sleep aid clinically because of its zero addictive properties and low abuse profile.
Zyprexa Dosage Information
a.) Typical Dosage Recommendations
Olanzapine or Zyprexa is available, commercially, as a tablet in strengths of 2.5, 5, 7.5, 10, 15 and 20 mg. There also is available an orally disintegrating wafer called Zydis. This formulation dissolves on your tongue. Yet another form in which this medication is available is in the form of a 10 mg vial. This kind of intramuscular injection acts quickly and can be used for short term. Dosage depends upon how a patient responds and reacts to the drug. Oral form of the drug should be given only once in a day and preferably before bedtime since it is quite sedating. However, sedation will reduce as treatment pursues. 5 to 10 mg is the usual recommendation in the initial stages with a target dose of 10 mg every day. Zyprexa is not recommended for dosages above 20 mg every day.
b.) Missing A Dose
