| Summary: | Background: Chemotherapy induced neuropathy pain remains
as a major dose limiting side effect of many commonly used
chemotherapeutic drugs. Presently newer antiepileptic agents
have been developed with improved safety and tolerability
profiles in alleviating neuropathic pain.
Objectives: To evaluate the effect of Gabapentin and Pregabalin
in Paclitaxel (Taxol) induced neuropathic pain and to compare
the effect of these drugs in animal models.
Materials and Methods: Rats were randomly divided into
four groups of six animals each. Group 1- vehicle, Group 2
– Paclitaxel (2mg/kg), Group 3 - Gabapentin (60mg/kg) with
Paclitaxel, Group 4 - Pregabalin (30mg/kg) with Paclitaxel.
Pain was induced by intraperitoneal injection of Paclitaxel
on four alternate days. After taking the baseline values, the
drugs treated groups (group 3 and 4) were administered with
respective drugs once a day orally for eight consecutive days
along with paclitaxel. All the animals were tested for thermal
hyperalgesia and cold allodynia on day 0, 7, 14, 21 and 28 with
Radiant heat method and Tail immersion test, Acetone drop
method respectively.
Results: In Radiant heat method, gabapentin and pregabalin
treated animals found to have significant increase in the tail
latency period compared to control and paclitaxel treated
groups in all periods of observation. Acetone drop test and
tail immersion test also showed significant response similar
to Radiant heat method. Pregabalin showed highly significant
effect when compared to gabapentin group.
Conclusion: Both gabapentin and pregabalin produced significant anti-hyperalgesic and anti-allodynic effects in experimental
animal models. Pregabalin treated group showed highly significant effect compared to gabapentin treated animals. |
