Tiotropium bromide is a common drug used to treat asthma and is not hormonal and does not contain hormones. It is similar to the Chinese herbal medicine Yang Jin Hua, which used to be used to treat asthma, and is similar to the Western medicine tropics or 654-2 and other drugs that can relax smooth muscle, which are used in respiratory medicine to treat asthma. Since it is administered by inhalation, it has fewer side effects than the oral herbal medicine Yang Jin Hua, so it is a more commonly used medicine in clinical practice at present. Although it is not hormonal, it does have certain side effects. Elderly men suffering from cough and asthma often have prostate problems, and the use of tiotropium bromide may cause urinary discomfort, which is a side effect to be aware of, but its not a hormone.
