Application/Function of Cimetidine Powder.
Cimetidine, marketed in 1975, is the first selective H2 receptor antagonist used in the treatment of peptic ulcer. It mainly has the effect of inhibiting the secretion of gastric acid and reducing its acidity, which has a preventive and protective effect on corrosive gastritis caused by chemical irritation, and also has a significant effect on stress gastric ulcer and upper gastrointestinal bleeding. Acid control and pain relief, stomach protection and muscle production, hemostasis. Histamine H2 receptor antagonist. It can inhibit gastric acid secretion induced by histamine stimulation, and also inhibit gastric acid secretion induced by food, pentagastrin, caffeine and insulin, etc. It can also inhibit basal gastric acid secretion. It is used for gastric and duodenal ulcer, peptic esophagitis, and Zhuo-Ai syndrome.
Pharmacological Effects of Cimetidine Powder
This product is a histamine H2 receptor antagonist, which can reversibly inhibit the effect of histamine on H2 receptors. Therefore, it can inhibit the secretion of gastric acid caused by basic gastric acid and various stimuli, and prevent peptic ulcers. It can enhance cellular immune function, inhibit the activity of suppressive T cells, and have immunostimulatory effects on lymphocytes. It also has anti-androgenic effects, can block the binding of dihydrotestosterone to hair follicle receptors, and inhibit the secretion of skin glands.
It also has antiviral effect, local anesthetic and analgesic effect and antipruritic effect. It is rapidly absorbed after oral administration, with peak blood concentration in 60-90 minutes after administration and biological half-life of about 2 hours. The peak time is significantly delayed and the half-life is prolonged when the drug is taken during meals. When 0.4g is taken on an empty stomach, the effective blood concentration can be maintained for more than 4 hours, and the acid-suppressive effect lasts for 5-6 hours.
It can pass the blood-brain barrier, and the concentration in cerebrospinal fluid is about 1/4 of that in blood; it can also pass the placental barrier, and can be secreted into breast milk. 80% of the drug is excreted by kidney in its original form within 24 hours. In patients with renal insufficiency, excretion is reduced and the duration of drug action is prolonged.
