1. Metoclopramide and ranitidine are both H₂ receptor antagonists with extremely strong acid-suppressing effects. Typically, in addition to gastric and duodenal ulcers, chronic gastritis, HBG (gastric cirrhosis), and gastrointestinal bleeding are all accompanied by increased acidic gastric secretions, making these two drugs suitable for treatment. The former is 0.2 g, taken three times daily; the latter is 0.15 g, taken three times daily.

2. 654-2 (scopolamine), 10 mg per ampoule, has the same effect as atropine but with only one-twentieth of the toxic side effects. It was first invented by Professor Yang Guodong of China and is particularly effective in treating infectious and toxic shock at high doses. A dose of 20 mg can be administered directly into the vein, repeated every 10 minutes. The usual dosage is 20 mg mixed into 250 mL of 0.9% sodium chloride solution, which can treat chronic gastrointestinal bleeding with low blood pressure, as well as bradycardia, bronchial asthma, biliary and pancreatic pain, and gastric colic.

3. Persantin 25 mg, used for coronary vasodilation and treatment of angina pectoris. Recent reports indicate that it can also be used to treat chronic renal failure by dilating renal arterioles and increasing blood flow.
