Mexiletine is an orally effective antiarrhythmic agent which has also been found to be effective for myotonia and neuropathic pain. Mexiletine exerts its efficacy through blocking sodium channels (IC₅₀ : 75±8 μM for tonic block, 23.6±2.8 μM for use-dependent block), therefore can be used for cardiovascular and neurological research.

For research use only. We do not sell to patients.

In Vitro

Mexiletine (10µM, 48 h) increases peak I_Na and late I_Na in HEK293A cells transfected with SCN5A-WT or SCN5A-1795insD while Mexiletine (10µM, 5 min) blocks the late I_Na^[3].

In Vivo

Mexiletine (30, 100 mg/kg, p.o., acute administration) reverses both mechanical allodynia and cold hyperalgesia in Oxaliplatin (HY-17371) induced rats^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Male Sprague-Dawley rats with Oxaliplatin (HY-17371)-induced neuropathic pain ^[4]
Dosage:

Oxaliplatin (4 mg /kg) and Mexiletine(10, 30, 100 mg/kg)
Administration:

Oxaliplatin, Intraperitoneal injection (i.p.)in days 1, 2, 8, 9, 15, 16, 22, and 23; Mexiletine, Oral gavage (p.o.), acute administration
Result:

100 mg/kg completely reversed the reduction of 50% paw withdrawal threshold by Oxaliplatin at 60 min after administration in the von Frey test, completely reversed the increase of number of withdrawal responses at 60 and 120 min after administration in the acetone test.
30 mg/kg partly reversed the symptom and 10 mg/kg did not reverse any symptom. The effect disappeared by 180 min after administration.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
