Generalized Anxiety Disorder/Fibromyalgia/Diabetic Peripheral Neuopathy Pain: Initially 1 LOXX 30 once daily for a week and then 1 LOXX 60 once daily. Dose can be increased by 30 mg/day up to a maximum 120 mg duloxetine per day.
Overdosage
There is no specific antidote to Duloxetine (Loxx 30/Loxx 60) Delayed Release Capsules, but if serotonin syndrome ensues, specific treatment (such as with cyproheptadine and/or temperature control) may be considered. In case of acute overdose, treatment should consist of those general measures employed in the management of overdose with any drug.
An adequate airway, oxygenation, and ventilation should be assured and cardiac rhythm and vital signs should be monitored. Induction of emesis is not recommended. Gastric lavage with a large-bore orogastric tube with appropriate airway protection, if needed, may be indicated if performed soon after ingestion or in symptomatic patients.
Activated charcoal may be useful in limiting absorption of duloxetine from the gastrointestinal tract. Administration of activated charcoal has been shown to decrease AUC and Cmax by an average of one-third, although some subjects had a limited effect of activated charcoal. Due to the large volume of distribution of this drug, forced diuresis, dialysis, hemoperfusion, and exchange transfusion are unlikely to be beneficial.
In managing overdose, the possibility of multiple drug involvement should be considered. A specific caution involves patients who are taking or have recently taken Duloxetine (Loxx 30/ Loxx 60) Delayed Release Capsules and might ingest excessive quantities of tricyclic antidepressants. In such a case, decreased clearance of the parent tricyclic and/or its active metabolite may increase the possibility of clinically significant sequelae and extend the time needed for dose medical observation.
Administration
Contraindications
Duloxetine (Loxx 30/Loxx 60) Delayed Release Capsules is not advocated along with MAOIs, serotonin precursors such as tryptophan and thioridazine.
Warnings
Duloxetine (Loxx 30/Loxx 60) Delayed Release Capsules should be discontinued in patients who develop jaundice or other evidence of clinically significant liver dysfunction, symptomatic orthostatic hypotension and/or syncope, symptomatic hyponatremia, or urinary hesitancy and retention. Blood pressure should be measured prior to initiating treatment and periodically measured throughout the duration for which Duloxetine (Loxx 30/Loxx 60) Delayed Release Capsules is taken.
Treatment with Duloxetine (Loxx 30/Loxx 60) Delayed Release Capsules and any concomitant serotonengic or antidoperninergic agents, including antipsychotics, should be discontinued immediately serotonin syndrome or NMS-like reactions occur and supportive symptomatic treatment should be initiated.
Duloxetine (Loxx 30/Loxx 60) Delayed Release Capsules should ordinarily not be prescribed to patients with substantial alcohol use. Smoking can reduce bioavailability of Duloxetine (Loxx 30/Loxx 60) Delayed Release Capsules by about one-third. It should be advocated with due precaution along with aspirin, NSAIDs, warfarin and other anti-coagulants.

Action
The apparent volume of distribution averages about 1640 L. Duloxetine (Loxx 30/Loxx 60) is highly bound (>90%) to proteins and binding is primarily to albumin and a1-acid glycoprotein.
Duloxetine (Loxx 30/Loxx 60) undergoes extensive metabolism and only about 3% of the total absorbed occurs as unchanged drug in plasma. The major biotransformation pathways for duloxetine involve oxidation of the naphthyl ring followed by conjugation and further oxidation. Both CYP1A2 and CYP2D6 catalize the oxidation of the naphthyl ring. Metabolites found in plasma include 4-hydroxy duloxetine glucuronide and 5-hydroxy, 6-methoxy duloxetine sulfate.
Duloxetine (Loxx 30/Loxx 60) has an elimination half-life of about 12 hours (range 8 to 17 hours) and its pharmacokinetics is dose proportional over the therapeutic range. Elimination of duloxetine is mainly through hepatic metabolism involving two P450 isozymes, CYP1A2 and CYP2D6. Many additional metabolites have been identified in urine, some representing only minor pathways of elimination. Only trace (<1% of the dose) amounts of unchanged duloxetine are present in the urine. Most (about 70%) of the duloxetine dose appears in the urine as metabolites of duloxetine; about 20% is excreted in the feces. Duloxetine (Loxx 30/Loxx 60) undergoes extensive metabolism, but the major circulating metabolites have not been shown to contribute significantly to the pharmacologic activity of duloxetine.
