This invention discloses that a combination of two drugs, from two different and previously unrelated categories, provides effective and long-lasting relief from neuropathic pain. Both drugs can be taken orally, in a convenient, painless, non-invasive manner that does not require injections. One drug in this combination is an alpha2 adrenergic agonist, exemplified by clonidine. The other drug in the pain-relieving combination has a tri-cyclo-alkyl-amine (TCAA) structure. At least some TCAA drugs have antagonist (receptor-blocking) activity at two entirely different classes of neuronal receptors: the muscarinic subclass of acetylcholine (ACh) receptors, and the NMDA subclass of glutamate receptors. Such drugs include ethopropazine, normally used as an anti-cholinergic drug, and desipramine, normally used as an anti-depressant. Tests by the Applicants have shown that at least some TCAA drugs can relieve neuropathic pain to a limited extent, but at the doses required to relieve pain, they cause adverse side effects, and any pain relief is relatively brief and short-lived. However, when a TCAA drug such as ethopropazine is administered together with an alpha2 adrenergic agonist such as clonidine, these drugs mutually potentiate one another's neuropathic pain-relieving action, and provide potent and sustained neuropathic pain relief, even when each agent is administered at a low dosage that is below its threshold for causing adverse side effects. Accordingly, this drug combination can provide safe and effective relief of neuropathic pain and possibly other types of chronic and / or intractable pain, at dosages which are so low that they do not pose serious risks of adverse side effects.

The invention provides novel medical application of butylphthalide, i.e. the application of the butylphthalide in the preparation of a medicament for treating the bronchial asthma. The experimental research on the spasmolysis of the butylphthalide on the isolated tracheal smooth muscle of a guinea pig and the influence of the butylphthalide on the incubation period of asthma of the guinea pig shows that the butylphthalide in the concentration range of 3.68*10-6 to 3.68*10-4g / mL has obvious spasmolysis on the tracheal smooth muscle of the guinea pig in the isolated spasticity caused by 5*10-6g / mL of acetylcholine or histamine. On the basis of continuously applying the butylphthalide to the guinea pig which is sensitive for the acetylcholine and the histamine for 10 days, a mixture of the acetylcholine and the histamine is atomized and sucked and the incubation period of asthma is observed. A result shows that 30 mg / kg and 90 mg / kg of butylphthalide has an effect of relieving the tracheospasm of the guinea pig, which is caused by the acetylcholine and the histamine. Therefore, the butylphthalide has a treatment effect on the asthma guinea pig and the treatment effect of the butylphthalide on the asthma guinea pig is related to the effect of inhibiting Ca2+ inner flow and expanded tracheal smooth muscle of the butylphthalide.
