Description

Duloxetine Delayed-Release Capsules, USP: A Comprehensive Overview

Duloxetine Delayed-Release Capsules, USP, are a formulation of duloxetine, a selective serotonin and norepinephrine reuptake inhibitor (SSNRI) antidepressant. These capsules are designed to release the active ingredient gradually, providing therapeutic effects while minimizing side effects. Duloxetine is commonly prescribed for various conditions, including major depressive disorder (MDD), generalized anxiety disorder (GAD), diabetic peripheral neuropathic pain (DPNP), and chronic musculoskeletal pain.

Pharmacology

Duloxetine functions by inhibiting the reuptake of serotonin and norepinephrine in the central nervous system. This action increases the levels of these neurotransmitters in the synaptic cleft, which is believed to contribute to its antidepressant and analgesic effects. Duloxetine has minimal affinity for dopaminergic, cholinergic, histaminergic, opioid, glutamate, and GABA reuptake transporters, distinguishing it from other SNRIs.

Indications and Usage

Duloxetine Delayed-Release Capsules are indicated for:

• Major Depressive Disorder (MDD): The recommended starting dose is 40 mg/day, which may be increased to 60 mg/day after one week. The maximum recommended dose is 120 mg/day.
   
• Generalized Anxiety Disorder (GAD): The recommended dose is 60 mg/day.
   
• Diabetic Peripheral Neuropathic Pain (DPNP): The recommended dose is 60 mg/day.
   
• Chronic Musculoskeletal Pain: The recommended starting dose is 30 mg/day, which may be increased to 60 mg/day after one week.

Dosage and Administration

Duloxetine Delayed-Release Capsules should be swallowed whole and not crushed or chewed, as this may affect the enteric coating and release mechanism. The capsules can be taken with or without food. If a dose is missed, it should be taken as soon as remembered, unless it is almost time for the next dose; in that case, the missed dose should be skipped.

Contraindications

Duloxetine is contraindicated in:

• Patients with a known hypersensitivity to duloxetine or any component of the formulation.
   
• Patients with uncontrolled narrow-angle glaucoma.
   
• Patients with substantial alcohol use or chronic liver disease.
   
• Patients with severe renal impairment (glomerular filtration rate <30 mL/min)
•  

Warnings and Precautions

• Suicidal Thoughts and Behaviors: Antidepressants, including duloxetine, may increase the risk of suicidal thoughts and behaviors in children, adolescents, and young adults in short-term studies.
   
• Serotonin Syndrome: The use of duloxetine with other serotonergic drugs (e.g., triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, and St. John's Wort) may increase the risk of serotonin syndrome, a potentially life-threatening condition.
   
• Hypertension: Duloxetine may increase blood pressure. Blood pressure should be monitored regularly during treatment.
   
• Liver Injury: Duloxetine should be used with caution in patients with liver impairment, and its use is contraindicated in patients with chronic liver disease or cirrhosis.
   
• Urinary Hesitation and Retention: Cases of urinary retention have been reported. If symptoms develop, consideration should be given to the possibility that they might be drug-related.
