DULOXETINE HYDROCHLORIDE

Manufacturer: Aurobindo Pharma Limited

Score: 148.0

Quick Summary

Duloxetine is a selective serotonin and norepinephrine reuptake inhibitor (SNRI) used to treat major depressive disorder (MDD), generalized anxiety disorder (GAD), diabetic peripheral neuropathic pain (DPNP), fibromyalgia, and chronic musculoskeletal pain. It is available in delayed-release capsules and should be taken once daily with or without food. The recommended dosage varies by condition, with a typical starting dose of 40-60 mg/day for MDD and GAD, and 60 mg/day for DPNP, fibromyalgia, and chronic musculoskeletal pain. Duloxetine has several important safety considerations, including a boxed warning for increased risk of suicidal thoughts and behaviors in pediatric and young adult patients, and contraindications for use with monoamine oxidase inhibitors (MAOIs) and in patients with uncontrolled narrow-angle glaucoma. Common adverse reactions include nausea, dry mouth, somnolence, constipation, decreased appetite, and hyperhidrosis.

Special Population Considerations

Pregnancy

  • Use during pregnancy may be associated with increased risk of postpartum hemorrhage
  • Data from published literature and postmarketing retrospective cohort study have not identified a clear drug-associated risk of major birth defects or other adverse developmental outcomes

Nursing Mothers

  • Duloxetine is present in human milk
  • Monitor infants for sedation, poor feeding, and poor weight gain

Pediatric Use

  • Safety and effectiveness established for GAD in patients 7-17 years old
  • Not established for MDD, DPNP, fibromyalgia, or chronic musculoskeletal pain in pediatric patients

Geriatric Use

  • No overall differences in safety or effectiveness observed between geriatric and younger adult patients
  • Greater sensitivity of some older patients cannot be ruled out
  • Increased risk of hyponatremia and falls in geriatric patients
