Suicidality and Antidepressant Drugs
Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of SelfemraTM or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. SelfemraTM is not approved for use in pediatric patients with MDD and obsessive compulsive disorder (OCD) (see WARNINGS; PRECAUTIONS, Information for Patients; and PRECAUTIONS, Pediatric Use).
SelfemraTM (fluoxetine hydrochloride) is a selective serotonin reuptake inhibitor (SSRI) for oral administration; fluoxetine was initially developed and marketed as an antidepressant (Prozac®, fluoxetine capsules, USP).
SelfemraTM is indicated for the treatment of premenstrual dysphoric disorder (PMDD).
The efficacy of fluoxetine in the treatment of PMDD was established in 3 placebo-controlled trials (see CLINICAL TRIALS).
The essential features of PMDD, according to the DSM-IV, include markedly depressed mood, anxiety or tension, affective lability, and persistent anger or irritability. Other features include decreased interest in usual activities, difficulty concentrating, lack of energy, change in appetite or sleep, and feeling out of control. Physical symptoms associated with PMDD include breast tenderness, headache, joint and muscle pain, bloating, and weight gain. These symptoms occur regularly during the luteal phase and remit within a few days following onset of menses; the disturbance markedly interferes with work or school or with usual social activities and relationships with others. In making the diagnosis, care should be taken to rule out other cyclical mood disorders that may be exacerbated by treatment with an antidepressant.
The effectiveness of SelfemraTM in long-term use, that is, for more than 6 months, has not been systematically evaluated in controlled trials. Therefore, the physician who elects to use SelfemraTM for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

BACKGROUND: Currently available disease-modifying treatments acting by modifying

is caused by a widespread axonal degeneration. Mechanisms suspected to be
involved in this widespread axonal degeneration are reduced axonal energy

The Effects of Multiple Dose Fluoxetine and Metabolites on CYP1A2, CYP2C19, CYP2D6 and CYP3A4 Activity [Completed]
Inhibitory drug-drug interactions (DDIs) are a considerable concern as inhibition of drug's
clearance can lead to increased plasma concentrations and subsequent adverse events and
toxicities. Fluoxetine (ProzacŪ) is a widely prescribed antidepressant, but is also a potent
inhibitor of cytochrome P450 (CYP) enzymes. Fluoxetine was chosen as the model inhibitor for
this study because it is a clinically important inhibitor of multiple CYP enzymes with
varying potencies for each isoform. From in vitro data, fluoxetine is predicted to be a
moderate inhibitor of CYP2D6, but a strong inhibitor of CYP2C19 and CYP3A4. However, in vivo
fluoxetine causes a potent interaction with CYP2D6 and a weak-to-no interaction with CYP3A4.
The magnitude of the in vivo interaction of fluoxetine with CYP2C19 is not known. This in
vitro-to-in vivo discrepancy is of concern for two reasons: 1) In clinical drug development,
in vivo drug-drug interactions are tested only when in vitro experiments predict a risk for
in vivo DDIs and 2) Because in vivo DDI's are tested using a rank order approach of going
from the most potent in vitro interaction to the least potent until no interaction in vivo
is observed. In this study the interaction between fluoxetine and CYP3A4, CYP2C19 and CYP2D6
will be quantified simultaneously and the quantitative in vitro-to-in vivo predictions
tested. Fluoxetine will be orally administered daily for 14 days and CYP1A2, CYP3A4, CYP2C19
and CYP2D6 activity will be tested in the end of fluoxetine dosing using a cocktail of CYP
probes including caffeine, midazolam, omeprazole and dextromethorphan. Lovastatin will be
administered on a separate day and used as a second CYP3A4 probe to test whether CYP3A4
inhibition by fluoxetine depends on the contribution of intestinal CYP3A4 to the probe
clearance. Plasma and urine samples will be collected for 12 and 24 hrs, respectively,
during the control sessions (before fluoxetine administration) and for 24 hrs during the
treatment sessions (fluoxetine multiple dose). The concentrations of each of the probe drugs
and their metabolites (when applicable) as well as fluoxetine and its metabolites will be
measured in the collected samples and pharmacokinetic analysis will be performed. The
primary outcome measures for CYP inhibition will be the increase in the area under plasma
concentrations time curve (AUC) of each of the probes. The null hypothesis of this study is
that the area under plasma concentrations time curves (AUCs) of caffeine, dextromethorphan,
omeprazole, midazolam or lovastatin are the same between the control session and the
fluoxetine session. Because lovastatin has the greatest variability in its baseline
pharmacokinetics the study was powered based on the specific null hypothesis for lovastatin.
The alternative hypothesis is that fluoxetine decreases the clearance of the probe drugs
resulting in a significant increase in the AUCs between the control and study sessions.
Efficacy of Fluoxetine in Reducing Ictal Hypoventilation in Patients With Partial Epilepsy [Completed]
The purpose of this study is to determine the effects of fluoxetine on breathing mechanisms
during seizures. Patients with partial epilepsy commonly have changes in their breathing
mechanisms during seizures. These changes may increase the risk of serious side effects
from seizures, including sudden unexplained death in epilepsy (SUDEP), which affects 2-10
per 1000 patients with epilepsy each year. Fluoxetine (Prozac) may help to stimulate
breathing through its actions in the brain and has been shown to improve breathing changes
seen with seizures in certain animals. Fluoxetine is in a class of medications called
selective serotonin reuptake inhibitors (SSRIs). It works by increasing the amount of
serotonin, a natural substance in the brain, at synapses, the junctions at which nerve cells
in the brain communicate. Fluoxetine is currently approved by the United States Food and
Drug Administration (FDA) for the treatment of patients with Major Depressive Disorder,

Fluoxetine Prevention Trial [Not yet recruiting]
Many cancer survivors are experiencing problems with memory and other cognitive abilities
following cancer treatment. Little is known concerning the contributions of potentially
preventive therapies on cognitive function, but animal studies have pointed to the potential
value of the medication fluoxetine in this context. We aim to determine whether six months
of fluoxetine therapy can preserve brain function in patients who have undergone
chemotherapy, and examine potential biological mechanisms for its protective effects in
humans. If use of fluoxetine in cancer patients can be validated in this manner, it will
represent the first drug demonstrated to prevent cerebral dysfunction associated with
exposure to chemotherapy. Moreover, as this involves an agent that is already FDA-cleared
for other indications, widely commercially available throughout the U. S. and other parts of
the world, and relatively inexpensive since it is obtainable in generic formulations, it
would represent a pharmacologic approach that is amenable to rapid translation to the
