Abstract:
Aim The nasal absorption of furosemide and promotion action of l_menthol was examined. Methods In situ nasal recirculation methods was used to study the does_effect relationship of nasal absorption of furosemide and the effect of l_menthol on nasal absorption of furosemide in rats. Results When the concentration of furosemide in circulation liquid was respectively(4.66?0.33) ?(9.76?0.45) and (18.83?1.89) ?g?ml-1,the absorption rate constant k(min-1) of nasal in situ was correspondingly 0.0067?0.0011,0.0134?0.0024 and 0.0163?0.0037;and urine liquid appearing time was (73.33?1.53)?(52.67?7.02) and (47.00?4.58) min.But the larger the concentration of l_menthol, the little the absorption rate constant k. Conclusion Furosemide can be absorbed through the nasal mucous, and l_menthol can promote its absorption.
