Screening of prescriptions of JIUFEN SPRAY by transdermal experiments / 中草药

Object To screen the prescriptions of JIUFEN SPRAY Methods Four prescriptions were primarily obtained from 19 prescriptions of JIUFEN SPRAY on the basis of their stability and spraying effect, then the obtained four prescriptions were screened further according to transdermal rate of them Results Prescription 17th was considered to be the best as its high stability, spraying effect and transdermal rate Conclusion The optimal prescription of JIUFEN SPRAY consisted of 20% alcohol solution of sample, 3% borneol and 5% glycerine

Screening of the Receiving Solution in Transdermal Absorption of Jiufen Spray / 中药新药与临床药理

Objective: To screen the receiving solution used to study the transdermal absorption of strychnine in Jiufen spray. Methods: With recovery,Q-T equation and transdermal speed constant as the parameters, the improved Franz-cell and the skin of SD rats were used to screen the receiving solution from saline, saline-alcohol (7∶3,v∶v), pH phosphate buffer solution-alcohol (88∶2,v∶v), pH 7.4 phosphate buffer containing 25% alcohol. Results: The comparison of the inter-day and intra-day recoveries,Q-T equation and transdermal speed constant showed that saline-alcohol(7∶3) was the best for the study. Conclusion: It is indicated that saline-alcohol(7∶3) was the best receiving solution for the transdermal absorption study of Jiufen spray.
