Abstract

Background: Opiate withdrawal refers to the wide range of symptoms that occur after stopping or dramatically reducing opiate drugs after heavy and prolonged use. The aim of the present study was to determine the effects of Raha and Berberin medicine in toxic and sub toxic doses compare with Clonidine medicine on reducing symptoms of morphine withdrawal in Syrian mice.

 

Materials and method: 140 Syrian mice (weight range 70-90 gr) were divided randomly into 2 groups first group n1=35(receiving drug =21, control=14) & second group n2=105 (receiving drug=91, control=14). Animals were treated by injected increasing doses of morphine sulfate for physical dependence. Then withdrawal syndrome was induced by administration of Naloxone. In order to evaluate the effect of Raha Berberin and Clonidine on morphine withdrawal syndrome in Syrian mice and also amount of total alkaloids and Berberin value in the Raha® were measured.

 

Result: Total of average of alkaloid and Berberin value was 120, 5.72 mg, respectively in 5 ml of the Raha®. The rate of alcohol in Raha® was shown by using the USP procedure which was 19.34 percent. Toxic doses of Raha® and Berberin were 4, 40 mg/kg, respectively. Results indicated that, Raha increases significantly the percent of occurrence of ptosis and immobility were compared with control group (distilled water receiver) (p=0.016). The occurrence rate of sniffing, grooming and rearing behavior in Raha and Berberin treated groups compared with control group, within 15min period, was not found statistically significant (p=0.089).

 

Conclusion: Based on our study both Raha® and Berberin in any dilution had no effect on reducing signs of opioid withdrawal syndrome. According to the lack of its effect in mice, further studies should be undertaken for prescription of this drug in human.
