Pharmacodynamical mechanism study of “Heat Asthma Formula” in treatment of bronchial asthma

Objective: In this paper the pharmacodynamical mechanism of Heat Asthma Formula(HAF)(Herba Ephedrae, Rhizoma pinelliae, Flos Lonicerae, etc) in the treatment of bronchial asthma was discussed. Methods: By means of the radio labelled aglycone, applying phlogistic medium TXB2, β receptor on bronchus and cyclic nucleotide (cAMP/cGMP) in lung tissue used as observed targets. Results: The results showed HAF could inhibit the release of phlogistic medium TXB2, improve the conjugate rate of β receptor, adjust the proportion between cAMP and cGMP. Conclusion: The treatment on bronchial asthma of “Heat Asthma Formula” was perhaps concerned with above mentioned contents.
