The drugs for treating stomachache should be selected according to the different causes of stomachache. For example, if the stomachache is caused by gastrointestinal spasm, you can take antispasmodic drugs. The most commonly used drugs are belladonna tablets or 654-2 injection. If the abdominal pain is caused by gastrointestinal infection, antibiotics and probiotics should be used, including amoxicillin or cephalosporins, and probiotics in the gut include peifeikang, jejunsheng and other drugs. In addition, you can also take drugs that regulate intestinal peristalsis, including trimebutine maleate or mosapride, to treat stomach pain caused by gastrointestinal infection. If the abdominal pain is not caused by the digestive system, for example, if it is caused by urinary calculi or dysmenorrhea, you can take pain relief drugs, such as loxoprofen sodium or ibuprofen tablets.
