What is Flupirtine maleate?

Description

Flupirtine maleate is a centrally-acting, non-addicting analgesic agent somewhat more potent than aspirin, paracetamol and pentazocine. It is reported to be useful in the treatment of postoperative and dental pain.

Description

Flupirtine is an activator of voltage-gated potassium channel 7 (K_v7/KCNQ). It induces relaxation of preconstricted pulmonary arteries isolated from wild-type and serotonin transporter-overexpressing (SERT⁺) mice. Flupirtine (30 mg/kg per day) decreases mean right ventricular pressure and right ventricular hypertrophy in hypoxia-induced and SERT⁺ mouse models of pulmonary arterial hypertension. It increases the paw withdrawal threshold in a rat model of streptozotocin-induced diabetic neuropathy when administered at a dose of 10 mg/kg and increases paw withdrawal latency in a rat model of carrageenan-induced paw inflammation when used in combination with morphine. Flupirtine also indirectly antagonizes NMDA receptors via its effects on potassium channels.
