Generic Cymbalta Information

Introduction

Cymbalta, whose active compound is duloxetine, belongs to the class of serotonin‑norepinephrine reuptake inhibitors (SNRIs). It is approved for the treatment of major depressive disorder (MDD), generalized anxiety disorder (GAD), diabetic peripheral neuropathic pain, fibromyalgia, and chronic musculoskeletal pain. In Hong Kong, Cymbalta is prescribed by psychiatrists, neurologists, and pain specialists under the regulation of the Pharmacy and Poisons Ordinance. The medication is marketed by Eli Lilly and its generic equivalents are manufactured by several internationally licensed producers.

What is Cymbalta?

Cymbalta is an oral, film‑coated tablet that contains 20 mg, 30 mg, or 60 mg of duloxetine. It is classified as an SNRI, a pharmacological group that inhibits the re‑uptake of both serotonin (5‑HT) and norepinephrine (NE) neurotransmitters, thereby increasing their synaptic availability. Duloxetine was first developed in the early 200s and received approval from the United States Food and Drug Administration (FDA) in 2004. The brand‑name product is manufactured by Eli Lilly; generic versions are sold under the name duloxetine by multiple certified suppliers.

How Cymbalta Works

Duloxetine binds competitively to the serotonin and norepinephrine transporters in the central nervous system. By preventing re‑absorption of these neurotransmitters, the drug raises their concentrations at synaptic clefts, which modulates mood, pain perception, and stress responses. The increase in serotonergic activity contributes to antidepressant and anxiolytic effects, while enhanced norepinephrinergic signaling improves descending pain inhibition pathways. After oral administration, peak plasma concentrations are reached within 6 hours; the drug’s half‑life is approximately 12 hours, allowing once‑daily dosing. Duloxetine is metabolised primarily by CYP1A2 and CYP2D6 enzymes and cleared renally.

Conditions Treated with Cymbalta

• Major depressive disorder (MDD): Clinical trials demonstrated a statistically significant reduction in Hamilton Depression Rating Scale scores versus placebo. Depression prevalence in Hong Kong is estimated at 5–7 % of the adult population.
• Generalized anxiety disorder (GAD): Randomised controlled studies showed improvement in the Hamilton Anxiety Rating Scale, supporting its use as a first‑line anxiolytic.
• Diabetic peripheral neuropathic pain: Duloxetine reduces pain intensity in patients with type 2 diabetes, a growing concern in Hong Kong’s ageing demographic.
• Fibromyalgia: Evidence indicates relief of widespread musculoskeletal pain and improvement in sleep quality.
• Chronic musculoskeletal pain (e.g., osteoarthritis, chronic lower‑back pain): The dual neurotransmitter action addresses both affective and nociceptive components of chronic pain.

Patient Groups Most Likely to Benefit

• Adults aged 18 years and older with a confirmed diagnosis of MDD or GAD, especially those who have not responded adequately to selective serotonin re‑uptake inhibitors (SSRIs).
• Patients with type 2 diabetes experiencing persistent peripheral neuropathic pain despite optimal glycaemic control.
• Individuals diagnosed with fibromyalgia who exhibit moderate‑to‑severe pain scores and sleep disturbance.
• Older adults (≥65 years) when renal function is assessed, as duloxetine’s clearance is partially renal.
• Contraindications / caution: Patients with severe hepatic impairment, uncontrolled narrow‑angle glaucoma, or a history of serotonin syndrome should avoid duloxetine. Use caution in those receiving concomitant monoamine oxidase inhibitors (MAOIs) or potent CYP2D6 inhibitors.

Risks, Side Effects, and Interactions

Common

• Nausea, dry mouth, constipation, or diarrhoea.
• Headache and dizziness, particularly after the first week of therapy.
• Insomnia or somnolence; dose timing may be adjusted to mitigate.
• mild increase in blood pressure; routine monitoring is advised.

Rare

• Elevated liver enzymes (ALT, AST) suggesting hepatocellular stress.
• Hyponatraemia, especially in elderly patients or those on diuretics.
• Sexual dysfunction (decreased libido, erectile dysfunction, delayed orgasm).

Serious

• Serotonin syndrome: Hyperthermia, agitation, tremor, hyperreflexia; requires immediate medical attention.
• Suicidal ideation: Increased risk at therapy initiation, particularly in younger adults (≤24 years).
• Severe hepatic injury: Rare but possible; discontinue if liver function tests rise sharply.
• Severe hypertension: May develop in patients with pre‑existing cardiovascular disease.

Drug–Drug Interactions

• MAOIs: Must discontinue MAOI at least 14 days before starting duloxetine.
• CYP2D6 inhibitors (e.g., quinidine, bupropion): May increase duloxetine plasma levels; dosage adjustment may be required.
• CYP1A2 inducers (e.g., smoking, carbamazepine): May reduce duloxetine exposure, possibly diminishing efficacy.
• Anticoagulants (warfarin, direct oral anticoagulants): Duloxetine can increase bleeding risk; monitor INR or clinical signs of bleeding.
• NSAIDs and aspirin: Concurrent use may exacerbate gastrointestinal bleeding risk, especially in patients with a history of ulcers.

Practical Use: Dosing, Missed Dose, Overdose

• Typical adult dosing for depression or anxiety: 60 mg once daily; may start at 30 mg and titrate upward after one week based on tolerance.
• Neuropathic pain or fibromyalgia: 60 mg once daily, with an optional 30 mg increase after two weeks if needed.
• Renal impairment (CrCl < 30 mL/min): Reduce to 30 mg daily; avoid if CrCl < 10 mL/min.
• Missed dose: Take the missed tablet as soon as remembered unless it is within 6 hours of the next scheduled dose; then skip and continue the regular schedule. Doubling up is not recommended.
• Overdose: Immediate medical evaluation is critical. Supportive measures include gastric lavage, activated charcoal, and monitoring of cardiac and respiratory status. No specific antidote exists.
• Food and alcohol: Take the tablet with food to minimise gastrointestinal upset. Limit alcohol, as combined central nervous system depression may increase dizziness.
