🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions. Duloxetine inhibits the reuptake of serotonin and norepinephrine at nerve synapses, increasing their availability in the central nervous system. This enhances descending pain inhibition pathways and improves mood. Methylcobalamin is a coenzyme that supports methionine synthase activity, which is essential for myelin synthesis and nerve cell maintenance. Together, they help reduce neuropathic pain and support nerve health.
Mechanism Steps
💡 How to Take symbal m 20mg/500mcg tablet
Strength: Capsule containing Duloxetine 20 mg and Methylcobalamin 500 mcg.
Dosage Information
| Adult Dosage | The usual adult dose of this medicine is one capsule taken orally once daily, preferably at the same time each day. The dose may be increased based on your response and tolerability, but the maximum recommended dose is generally 60 mg of Duloxetine per day for neuropathic pain. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not exceed the prescribed dose. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may be more sensitive to the effects of this medicine. Start with a lower dose and titrate slowly. Monitor for hyponatremia, falls, and other side effects. Dose must be individualized by a qualified clinician. |
| Renal Impairment | For patients with mild to moderate renal impairment (CrCl 30-80 mL/min), no dose adjustment is usually needed. For severe renal impairment (CrCl <30 mL/min) or end-stage renal disease, Duloxetine is not recommended. Methylcobalamin is generally safe. Consult your doctor for individualized dosing. |
| Hepatic Impairment | Duloxetine is not recommended in patients with severe hepatic impairment. In mild to moderate hepatic impairment, dose reduction may be necessary. Methylcobalamin is generally safe. Dose must be individualized by a qualified clinician. |
| Maximum Daily Dose | The maximum recommended daily dose of Duloxetine is 120 mg, but for neuropathic pain, doses above 60 mg/day have not been shown to be more effective and may increase side effects. The maximum daily dose of Methylcobalamin is not well established but typical doses are up to 1500 mcg per day. |
