BACKGROUND
Long term use of NSAIDs, opioids and corticosteroids was associated with serious adverse effects. Hence, the search for a safer analgesic and anti-inflammatory agent was always going on. It was considered worthwhile to evaluate analgesic and anti-inflammatory activities of Holoptelea integrifolia and Argyreia speciosa.
OBJECTIVE
To evaluate analgesic and anti-inflammatory activities of aqueous extract of leaves of Holoptelea Integrifolia and methanolic extract of Argyreia Speciosa root powder in mice and rats.
METHODS
After obtaining permission from animal ethics committee, the animals were divided into 7 groups of 6 animals each {control, standard - ibuprofen 100mg/kg, Holoptelea integrifolia (250 and 500 mg/kg), Argyreia speciosa (100 and 300 mg/kg) and combination of Holoptelea integrifolia (250 mg/kg) and Argyreia speciosa (100 mg/kg)}. The analgesic activity of the extracts was evaluated using tail-flick with radiant heat and acetic acid induced writhing method and the anti-inflammatory activity was evaluated using carrageenan induced paw oedema method.
METHODS
One-way ANOVA followed by post-hoc test. p < 0.05 was considered to be significant.
RESULTS
In tail-flick method, both Holoptelea integrifolia and Argyreia speciosa produced significant (p<0.05) increase in latency as compared to control, their combination showed a significant increase in latency as compared to control as well as to the standard - ibuprofen. In writhing method, Holoptelea integrifolia and Argyreia speciosa, alone and in combination, significantly decreased the number of writhes as compared to control. In paw oedema method, both Holoptelea integrifolia and Argyreia speciosa showed significant inhibition of paw oedema as compared to control and the activity was comparable to ibuprofen.
CONCLUSIONS
Extracts of Holoptelea integrifolia and Argyreia speciosa exhibits significant central and peripheral analgesic and anti-inflammatory activity.
