Fluoxetine potentially may alter blood glucose concentrations. Hypoglycemia has occurred in less than 1% of patients receiving fluoxetine and hypoglycemic reaction has occurred rarely. In addition, hyperglycemia has developed following discontinuance of the drug. Therefore, the possibility that insulin and/or oral sulfonylurea antidiabetic agent dosage adjustments may be necessary when fluoxetine therapy is initiated or discontinued in patients with diabetes mellitus should be considered.

The most frequent adverse effect associated with fluoxetine therapy is nausea, which occurs in about 21% of patients. Nausea generally is mild, occurs early in therapy, and usually subsides after a few weeks of continued therapy with the drug. ... Diarrhea occurs in about 12%, anorexia in about 9%, and dyspepsia in about 6% of patients receiving the drug; limited evidence suggests that the incidence of anorexia may be dose-related. Other adverse GI effects associated with fluoxetine therapy include abdominal pain and change in taste perception, which occur in approximately 3 and 2% of patients, respectively; taste loss has been reported rarely. Vomiting, melena, and flatulence reportedly occur in about 2% and gastroenteritis in about 1% of patients receiving the drug. Increased appetite has been reported in more than 1% of patients receiving fluoxetine, but has not been definitely attributed to the drug. Other adverse GI effects, including aphthous stomatitis, dysphagia, eructation, esophagitis, gastritis, gingivitis, glossitis, melena, stomatitis, and thirst, have been reported in less than 1% of fluoxetine-treated patients; however, a causal relationship to the drug has not been established. Bloody diarrhea, colitis, duodenal or gastric ulcer, enteritis, fecal incontinence, hematemesis, hyperchlorhydria, increased salivation, mouth ulceration, salivary gland enlargement, tongue discoloration, and tongue edema have occurred rarely, but have not been definitely attributed to fluoxetine.

Because of the possibility of suicide in depressed patients, close supervision of high risk patients is recommended during initial fluoxetine therapy. To reduce the risk of overdosage, the drug should be prescribed in the smallest quantity consistent with good patient management. Suicidal ideation may persist until substantial remission of the depressive disorder occurs.

QN06AB03
Fluoxetine hydrochloride appears to be well absorbed from the GI tract following oral administration. The oral bioavailability of fluoxetine in humans has not been fully elucidated to date, but at least 60-80% of an oral dose appears to be absorbed. However, the relative proportion of an oral dose reaching systemic circulation unchanged currently is not known. Limited data from animals suggest that the drug may undergo first-pass metabolism and extraction in the liver and/or lung following oral administration. In these animals (beagles), approximately 72% of an oral dose reached systemic circulation unchanged. Food appears to cause a slight decrease in the rate, but not the extent of absorption of fluoxetine in humans.

Distribution of fluoxetine and its metabolites into human body tissues and fluids has not been fully characterized. Limited pharmacokinetic data obtained during long term administration of fluoxetine to animals suggest that the drug and some of its metabolites, including norfluoxetine, are widely distributed in body tissues, with highest concentrations occurring in the lungs and liver. The drug crosses the blood-brain barrier in humans and animals. In animals, fluoxetine: norfluoxetine ratios reportedly were similar in the cerebral cortex, corpus striatum, hippocampus, hypothalamus, brain stem, and cerebellum 1 hr after administration of single dose of the drug.

In order to confirm embryonic/fetal exposure to fluoxetine and/or metabolites, dissection and whole-body autoradiographic techniques were utilized to determine the placental transfer and fetal distribution in 12 and 18 day pregnant Wistar rats 1, 4, 8, and 24 hr following a single oral 12.5 mg/kg dose of (14)C fluoxetine. On gestation Days 12 (organogenesis) and 18 (postorganogenesis), peak concentrations of radiocarbon occurred 4-8 hr after dose administration in the placenta, embryo/fetus, amniotic fluid, and maternal kidney, brain, and lung, and declined slightly at 24 hr postdose. Maternal lung contained the highest tissue concentration of radiocarbon at all time points. Placenta and maternal brain, kidney, and liver contained moderate levels of radioactivity, while embryonic/fetal tissue, amniotic fluid, and maternal plasma contained low levels of radioactivity. Mean fetal concentrations of radiocarbon at 4, 8, and 24 hr on gestation Day 18 were higher than mean embryonic concentrations on Day 12 of gestation. Analytical characterization of radioactivity indicated that combined fluoxetine and norfluoxetine concentrations accounted for 63-80% of the total radiocarbon concentrations in embryonic/fetal tissue. Results indicated that embryonic/fetal and maternal tissue levels of fluoxetine were greatest at early time points and declined with time, while norfluoxetine tissue levels were highest at the 24 hr time point. Whole-body autoradiographic techniques demonstrated that radioactivity associated with (14)C fluoxetine and/or its metabolites traversed the placenta and distributed throughout the 18 day fetus 4 hr following dose administration. Visual and quantitative evaluations of the autoradiograms indicated that the highest fetal concentrations of radiocarbon were associated with brain and thymus. Results from these studies indicate that fluoxetine and norfluoxetine traverse the placenta and distribute within the embryo/fetus during the periods of organogenesis and postorganogenesis and confirm embryonic/fetal exposure of parent and metabolite in previous negative rat teratology and reproductive studies.

The present study was designed to define the kinetic behavior of fluoxetine N-demethylation in human liver microsomes and to identify the isoforms of cytochrome p450 (CYP) involved in this metabolic pathway. The kinetics of Ne formation of norfluoxetine was determined in human liver microsomes from six genotyped CYP2C19 extensive metabolizers (EM). The correlation studies between the fluoxetine N-demethylase activity and various CYP enzyme activities were performed. Selective inhibitors or chemical probes of various cytochrome P-450 isoforms were also employed. The kinetics of norfluoxetine formation in all liver microsomes were fitted by a single-enzyme Michaelis-Menten equation (mean Km=32 umol/L +/- 7 umol/L). Significant correlations were found between N-demethylation of fluoxetine at both 25 umol/L and 100 umol/L and 3-hydroxylation of tolbutamide at 250 micromol/L (r1=0.821, P1=0.001; r2=0.668, P2=0.013), respectively, and S-mephenytoin 4'-hydroxylase activity (r=0.717, P=0.006) at high substrate concentration of 100 umol/L. S-mephenytoin (SMP) (a CYP2C19 substrate) at high concentration and sulfaphenazole (SUL) (a selective inhibitor of CYP2C9) substantially inhibited norfluoxetine formation. The reaction was minimally inhibited by coincubation with chemical probe, inhibitor of CYP3A4 (triacetyloleandomycin, TAO). The inhibition of fluoxetine N-demethylation at high substrate concentration (100 umol/L) was greater in PM livers than in EM livers (73 % vs 45 %, P < 0.01) when the microsomes were precoincubated with SUL plus TAO. Cytochrome p450 CYP2C9 is likely to be a major CYP isoform catalyzing fluoxetine N-demethylation in human liver microsomes at a substrate concentration close to the therapeutic level, while polymorphic CYP2C19 may play a more important role in this metabolic pathway at high substrate concentration.

The exact metabolic fate of fluoxetine has not been fully elucidated. The drug appears to be metabolized extensively, probably in the liver, to norfluoxetine and several other metabolites. Norfluoxetine (desmethylfluoxetine) the principal metabolite, is formed by N-demethylation of fluoxetine, which may be under polygenic control. The potency and selectivity of norfluoxetine's serotonin-reuptake inhibiting activity appear to be similar to those of the parent drug. Both fluoxetine and norfluoxetine undergo conjugation with glucuronic acid in the liver, and limited evidence from animals suggests that both the parent drug and its principal metabolite also undergo O-dealkylation to form p-trifluoromethylphenol, which subsequently appears to be metabolized to hippuric acid.

The half-life of fluoxetine reportedly is prolonged (to approximately 4-5 days) after administration of multiple versus single doses, suggesting a nonlinear pattern of drug accumulation during long-term administration.

Following a single oral dose of fluoxetine in healthy adults, the elimination half-life of fluoxetine reportedly averages approximately 2-3 days (range: 1-9 days) and that of norfluoxetine averages about 7-9 days (range: 3-15 days).

The precise mechanism of antidepressant action of fluoxetine is unclear, but the drug has been shown to selectively inhibit the reuptake of serotonin (5-HT) at the presynaptic neuronal membrane. Fluoxetine-induced inhibition of serotonin reuptake causes increased synaptic concentrations of serotonin in the CNS, resulting in numerous functional changes associated with enhanced serotonergic neurotransmission.

Monoamine oxidase-B has been determined to be the enzyme responsible for the conversion of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine into its toxic metabolite 1-methyl-4-phenylpyridine ion. Since this enzyme has been localized primarily in astrocytes and serotonergic neurons, it would appear that 1-methyl-4-phenylpyridine ion is being produced outside the dopaminergic neurons. To investigate this possibility, the administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine was preceded by systemically administered fluoxetine. In keeping with its demonstrated ability to inhibit uptake into serotonergic neurons and serotonin uptake into astrocytes, fluoxetine pretreatment resulted in a significant attenuation of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine induced depletions of striatal dopamine and serotonin concentration. These results support the extra-dopaminergic production of 1-methyl-4-phenylpyridine ion.

Fluoxetine is a potent and selective inhibitor of the neuronal serotonin-uptake carrier and is a clinically effective antidepressant. Although fluoxetine is used therapeutically as the racemate, there appears to be a small but demonstrable stereospecificity associated with its interactions with the serotonin-uptake carrier. The goals of this study were to determine the absolute configurations of the enantiomers of fluoxetine and to examine whether the actions of fluoxetine in behavioral tests were enantiospecific. (S)-Fluoxetine was synthesized from (S)-(-)-3-chloro-1-phenylpropanol by sequential reaction with sodium iodide, methylamine, sodium hydride, and 4-fluorobenzotrifluoride. (S)-Fluoxetine is dextrorotatory (+1.60) in methanol, but is levorotatory (-10.85) in water. Fluoxetine enantiomers were derivatized with (R)-1-(1-naphthyl)ethyl isocyanate, and the resulting ureas were assayed by 1H NMR or HPLC to determine optical purities of the fluoxetine samples. Both enantiomers antagonized writhing in mice; following sc administration of (R)- and (S)-fluoxetine, ED50 values were 15.3 and 25.7 mg/kg, respectively. Moreover, both enantiomers potentiated a subthreshold analgesic dose (0.25 mg/kg) of morphine, and ED50 values were 3.6 and 5.7 mg/kg, respectively. Following ip administration to mice, the two stereoisomers antagonized p-chloroamphetamine-induced depletion of whole brain serotonin concentrations. ED50 values for (S)- and (R)-fluoxetine were 1.2 and 2.1 mg/kg, respectively. The two enantiomers decreased palatability-induced ingestion following ip administration to rats; (R)- and (S)-fluoxetine reduced saccharin-induced drinking with ED50 values of 6.1 and 4.9 mg/kg, respectively. Thus, in all biochemical and pharmacological studies to date, the eudismic ratio for the fluoxetine enantiomers is near unity.
