Acute pancreatitis has a rapid onset and progresses rapidly, seriously endangering the lives of patients. The current pharmacological treatment of pancreatitis can greatly reduce the mortality of patients. Currently commonly used drugs are: 1, inhibition of gastric acid secretion proton pump inhibitors such as pantoprazole and omeprazole can reduce gastric acid and pancreatic enzyme secretion, thereby reducing the occurrence of stress ulcers. 2, inhibition of pancreatic secretion and pancreatic enzyme activity trypsin inhibitors such as peptidase and doublester can inhibit trypsin. Stanozine (tetradecapeptide growth inhibitor) and Sunnin (octapeptide growth inhibitor) are the best drugs to inhibit pancreatic fluid and pancreatic enzyme activity in clinical practice. 3, antibiotic drugs pancreatitis secondary infection is mostly caused by Escherichia coli, Pseudomonas aeruginosa, Bacillus degenerans, etc.. But early pancreatitis is often not recommended to add antibiotics, for patients with pancreatic necrosis can use ceftazidime, imipenem, ornidazole and other anti-infective treatment. 4, antifungal agents severe acute pancreatitis patients with long-term use of antibiotics and decreased resistance can lead to fungal infections, aggravating the condition, when additional antifungal drugs such as fluconazole and amphotericin B are needed. 5, pain relief and antispasmodic drugs acute pancreatitis caused by severe pain often requires pain medication such as tramadol injection, diclofenac sodium, pethidine, etc. The commonly used antispasmodic drugs scopolamine or atropine can relieve Pain caused by spasm of the duodenal sphincter.
