Description
Overview of the medicine
Dsec 60 mg Capsule contains Duloxetine, a serotonin and norepinephrine reuptake inhibitor (SNRI). It is used to treat major depressive disorder, generalized anxiety disorder, neuropathic pain, chronic musculoskeletal pain, and fibromyalgia.
Uses & Indications
Dosage
Adults
Major Depressive Disorder/GAD: Initial 20-30 mg once daily, may increase to 60 mg/day. Max 120 mg/day. Neuropathic/Chronic pain/Fibromyalgia: Initial 30 mg once daily for 1 week, then 60 mg once daily.
Elderly
No specific dose adjustment for elderly with normal renal function, but caution is advised due to potential for increased sensitivity.
Renal_impairment
Not recommended for patients with end-stage renal disease (ESRD) or severe renal impairment (CrCl < 30 mL/min). For moderate impairment, caution is advised and dose reduction may be considered.
How to Take
Administer orally, with or without food. Swallow whole, do not chew or crush. Do not open the capsule and sprinkle its contents onto food or mix with liquids, as this may affect the enteric coating.
Mechanism of Action
Duloxetine selectively inhibits the reuptake of serotonin and norepinephrine in the central nervous system, thereby increasing the synaptic concentrations of these neurotransmitters. This action is believed to mediate its antidepressant, anxiolytic, and pain inhibitory effects.
Pharmacokinetics
Onset
Antidepressant effects typically observed within 1-4 weeks; pain relief may be faster.
Excretion
Primarily excreted in urine (about 70%) and feces (about 20%) as metabolites.
Half life
Approximately 12 hours (range 8-17 hours).
Absorption
Well absorbed orally, bioavailability is 32-80%. Peak plasma concentration reached in 6 hours.
Metabolism
Extensively metabolized in the liver by CYP1A2 and CYP2D6 to inactive metabolites.
Side Effects
Contraindications
- Hypersensitivity to duloxetine or any component of the formulation.
- Concomitant use with MAOIs (risk of serotonin syndrome).
- Uncontrolled narrow-angle glaucoma.
- Severe hepatic impairment or end-stage renal disease (ESRD) requiring dialysis.
Drug Interactions
MAOIs
Risk of serious, sometimes fatal, serotonin syndrome. Do not use concomitantly or within 14 days of discontinuing an MAOI.
Warfarin
Increased risk of bleeding.
SSRIs/SNRIs/Tricyclic Antidepressants
Increased risk of serotonin syndrome.
CYP2D6 inhibitors (e.g., paroxetine, quinidine)
May increase duloxetine plasma levels.
CYP1A2 inhibitors (e.g., fluvoxamine, ciprofloxacin)
May significantly increase duloxetine plasma levels.
Storage
Store in a cool, dry place, below 30°C. Protect from light and moisture. Keep out of reach of children.
Overdose
Symptoms include somnolence, coma, serotonin syndrome, seizures, vomiting, and tachycardia. Management is symptomatic and supportive; maintain airway, monitor cardiac and vital signs. Activated charcoal may be useful soon after ingestion.
