Schematic overview of studies involving lamotrigine in human experimental pain models
Reference | Dose | Model | Main findings | |
---|---|---|---|---|
Acute models | [77] (n= 18) | 400 mg p.o. | Heat skin stimulation (1 min 45 °C) VAS | No parameters were affected |
[76] (n= 12) | 300 mg p.o. | Stimulation of nasal mucosa by CO2 VAS, evoked brain potentials | VAS ↔ Evoked potentials: latency of the P100↑, amplitudes ↔ | |
[78] (n= 14) | 300 mg p.o. | Heat and cold skin stimulation 1–1.5 °C s−1) warm and cool sensation, PDT Mechanical skin stimulation threshold to touch | No parameters were affected | |
[81] (n= 12) | 300 mg p.o. | Cold pressor test maximum pain (VAS) | Maximum pain ↓ | |
Models inducing hyperalgesia | [77] (n= 18) | 400 mg p.o. | Heat-capsaicin sensitization area of secondary HA to pinprick and allodynia to brushing | No parameters were affected |
[78] (n= 14) | 300 mg p.o. | Intradermal capsaicin: area of secondary HA to pinprick, stroking and heat | No parameters were affected |
In the column ‘Model’ the method for pain assessment is normal font, and the method for pain induction is bold. PDT, pain detection threshold; PTT, pain tolerance threshold; AUC, area under curve; VAS, visual analogue scale; HA, hyperalgesia.
