The oral solution contains fluoxetine hydrochloride equivalent to 20 mg/5 ml (64.7 mcmol) of fluoxetine. It also contains alcohol 0.23%, benzoic acid, flavoring agent, glycerin, purified water, and sucrose. A study was conducted involving depressed outpatients who had responded (modified HAMD-17 score of ≤ 7 during each of the last 3 weeks of open-label treatment and absence of major depressive disorder by DSM-III-R criteria) by the end of an initial 12-week open-treatment phase on Fluoxetine 20 mg/day. These patients (N=298) were randomized to continuation on double-blind Fluoxetine 20 mg/day or placebo. At 38 weeks (50 weeks total), a statistically significantly lower relapse rate (defined as symptoms sufficient to meet a diagnosis of major depressive disorder for 2 weeks or a modified HAMD-17 score of ≥14 for 3 weeks) was observed for patients taking Fluoxetine compared with those on placebo. Comparative effects of nefazodone and fluoxetine on sleep in outpatients with major depressive disorder - History, rationale, and description More particularly, the present invention relates to a process for the preparation of highly pure (purity more than 99%) fluoxetine of Formula I and its pharmaceutically acceptable acid addition salts, preferably hydrochloride, which comprises reacting N-methyl-3-hydroxy-3-phenyl propylamine of Formula II with 1-chloro-4-(trifluoromethyl)benzene of Formula IV in the presence of alkaline metal hydroxide in sulfolane in the presence of a catalyst.

There have been rare postmarketing reports describing patients with weakness, hyperreflexia, and incoordination following the use of a selective serotonin reuptake inhibitor (SSRI) and sumatriptan. If concomitant treatment with sumatriptan and an SSRI (e.g., fluoxetine, fluvoxamine, paroxetine, sertraline, or citalopram) is clinically warranted, appropriate observation of the patient is advised. It should be noted that fluoxetine is approved in the pediatric population only for major depressive disorder and obsessive compulsive disorder. Carcinogenicity The dietary administration of Fluoxetine to rats and mice for 2 years at doses of up to 10 and 12 mg/kg/day, respectively (approximately 1.2 and 0.7 times, respectively, the maximum recommended human dose [MRHD] of 80 mg on a mg/m2 basis), produced no evidence of carcinogenicity. The efficacy of Fluoxetine for the treatment of major depressive disorder was demonstrated in two 8- to 9-week placebo-controlled clinical trials with 315 pediatric outpatients ages 8 to ≤18 (see

Fluoxetine was the first of the class of antidepressants called selective serotonin reuptake inhibitors (SSRIs) to be approved for use in the United States. In 2000, fluoxetine was approved by the FDA for use in treating premenstrual dysphoric disorder. 5. The tablet of claim 1 wherein fluoxetine is present as fluoxetine hydrochloride. There have been rare postmarketing reports describing patients with weakness, hyperreflexia, and incoordination following the use of a selective serotonin reuptake inhibitor (SSRI) and sumatriptan. If concomitant treatment with sumatriptan and an SSRI (e.g., fluoxetine, fluvoxamine, paroxetine, sertraline, or citalopram) is clinically warranted, appropriate observation of the patient is advised. Liquid: Oral Solution is available in: 20 mg per 5 mL with mint flavor. It contains Fluoxetine HCl equivalent to fluoxetine 20 mg. In depressed patients on dialysis (N = 12), fluoxetine administered as 20 mg once daily for 2 months produced steady-state fluoxetine and norfluoxetine plasma concentrations comparable to those seen in patients with normal renal function. While the possibility exists that renally excreted metabolites of fluoxetine may accumulate to higher levels in patients with severe renal dysfunction, use of a lower or less frequent dose is not routinely necessary in renally impaired patients (see Use in Patients With Concomitant Illness under PRECAUTIONS and DOSAGE AND ADMINISTRATION).

U.S. Fluoxetine clinical trials as of May 8, 1995 (10,782 patients) included 687 patients ≥65 years of age and 93 patients ≥75 years of age. The efficacy in geriatric patients has been established (see Five patients receiving fluoxetine in combination with tryptophan experienced adverse reactions, including agitation, restlessness and gastrointestinal distress. The half-life of concurrently administered diazepam may be prolonged in some patients (see Accumulation and Slow Elimination under CLINICAL PHARMACOLOGY). Coadministration of alprazolam and fluoxetine has resulted in increased alprazolam plasma concentrations and in further psychomotor performance decrement due to increased alprazolam levels.

Whether these systemic events and rash have a common underlying cause or are due to different etiologies or pathogenic processes is not known. Furthermore, a specific underlying immunologic basis for these events has not been identified. Upon the appearance of rash or of other possibly allergic phenomena for which an alternative etiology cannot be identified, Fluoxetine should be discontinued. Fluoxetine adds to the effects of alcohol and other central nervous system depressants (e.g., antihistamines, sedatives, tranquilizers, sleeping medicine, prescription pain medicine, barbiturates, seizure medication, muscle relaxants). Be sure that your physician knows if you are taking these or any other medications.

The racemic mixture of fluoxetine (i.e. , a mixture of R and S stereoisomers) has antidepressant effect; however this racemic mixture causes adverse toxic or psychological effects, has a delayed onset of action, and has a low response rate. The S(+) isomer of fluoxetine does not cause these adverse toxic or psychological effects, has a rapid onset of action and has a high response rate. Thus, it is much more desirable to use the S(+) isomer of fluoxetine. In U.S. placebo-controlled clinical trials for OCD, insomnia was reported in 28% of patients treated with fluoxetine and in 22% of patients treated with placebo. Anxiety was reported in 14% of patients treated with fluoxetine and in 7% of patients treated with placebo. Fluoxetine hydrochloride is a white to off-white crystalline solid with a solubility of 14 mg/mL in water. A specific caution involves patients who are taking or have recently taken fluoxetine and might ingest excessive quantities of a TCA. In such a case, accumulation of the parent tricyclic and/or an active metabolite may increase the possibility of clinically significant sequelae and extend the time needed for close medical observation (see Other drugs effective in the treatment of major depressive disorder under PRECAUTIONS).

Since the introduction of fluoxetine, systemic events, possibly related to vasculitis and including lupus-like syndrome, have developed in patients with rash. Although these events are rare, they may be serious, involving the lung, kidney, or liver. Death has been reported to occur in association with these systemic events. optically pure S(+) fluoxetine which are useful in the treatment of migraine headaches, the treatment of pain, in particular chronic pain, and the treatment of obsessive-compulsive disorders. These novel 5 compositions also avoid the above-described unwanted, adverse toxic or psychological effects associated with the racemic mixture of fluoxetine. Thioridazine administration produces a dose-related prolongation of the QTc interval, which is associated with serious ventricular arrhythmias, such as torsades de pointes-type arrhythmias, and sudden death. This risk is expected to increase with fluoxetine-induced inhibition of thioridazine metabolism (see CONTRAINDICATIONS).

The pharmacokinetics of fluoxetine 20 mg/day have been evaluated in 21 pediatric patients with depression or obsessive compulsive disorder (OCD) for up to 62 days. Both fluoxetine and norfluoxetine steady-state concentrations were roughly 2 times greater in children from 6 to 12 years of age than in adolescents from 13 to < 18 years of age (i.e., 171 ng/mL vs. 86 ng/ml for fluoxetine and 195 ng/mL vs. 113 ng/ml for norfluoxetine respectively). This difference is due primarily to weight differences, with lower weight children exhibiting higher plasma concentrations than adolescents. No gender-specific differences were noted. As in adults, fluoxetine and norfluoxetine accumulated extensively in children. Steady-state in pediatric patients is reached in 3—4 weeks with daily dosing.

There is also less lowering of blood pressure, tachycardia and arrhythmias. Antidepressants increased the risk of suicidal thinking and behavior (suicidality) in short-term studies in children and adolescents with Major Depressive Disorder (MDD) and other psychiatric disorders. Anyone considering the use of fluoxetine tablets or any other antidepressant in a child or adolescent must balance this risk with the clinical need. Patients who are started on therapy should be 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. Fluoxetine is approved for use in pediatric patients with MDD and obsessive compulsive disorder (OCD). (See WARNINGS and PRECAUTIONS, Pediatric Use.) Fluoxetine comes as a capsule, tablet, and liquid to take by mouth. It is usually taken once or twice a day and may be taken with or without food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take fluoxetine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Preparation of N-methyl-3-[(4-trifluoromethyl)phenoxy]-3-phenyl propylamine hydrochloride (fluoxetine hydrochloride) Phospholipids are increased in some tissues of mice, rats, and dogs given fluoxetine chronically. This effect is reversible after cessation of fluoxetine treatment. Phospholipid accumulation in animals has been observed with many cationic amphiphilic drugs, including fenfluramine, imipramine, and ranitidine. The significance of this effect in humans is unknown. The efficacy of fluoxetine in children and adolescents was established in a 13 week, dose titration, clinical trial in patients with OCD, as defined in DSM-IV (see Clinical Trials). Based on experience in animals, which may not be relevant to humans, Fluoxetine-induced seizures that fail to remit spontaneously may respond to diazepam.
