Non-addictive antitussive drugs can inhibit the cough center, inhibit the pulmonary-vagus nerve reflex caused by lung and pleural stretch receptors, and relax bronchial smooth muscles. That is, it has both central and peripheral antitussive mechanisms.

In two clinical studies, it was found that simvastatin can moderately enhance the anticoagulant effect of bean-scented anticoagulants. Prothrombin time should be checked frequently before early anticoagulant therapy and simvastatin use in adults to determine whether there is a significant change in prothrombin time. When patients taking bean-scented derivatives have a stable prothrombin time, it is recommended to continue monitoring prothrombin time for a fixed period of time. If the dose of simvastatin is changed, the above procedure should be followed. In patients not taking anticoagulants, simvastatin treatment has never been reported to affect bleeding or prothrombin time.

This product is a thromboxane synthetase inhibitor that can inhibit the production of TXA2, thus having the effects of anti-platelet aggregation and vasodilation. Animal experiments have shown that intravenous administration can reduce plasma TXB2 levels and the Keto-PGF12/TXB2 ratio, inhibit platelet aggregation caused by different inducers, and prevent cerebral infarction caused by the middle cerebral artery in rats.

By hindering the bacterial transpeptidation process and inhibiting bacterial protein synthesis, it has antibacterial effects on a variety of Gram-positive aerobic bacteria, Gram-negative aerobic bacteria, anaerobic bacteria, sexually transmitted disease microorganisms and other microorganisms. The mechanism of action is the same as that of erythromycin, mainly binding to the 50S subunit of the bacterial ribosome to inhibit RNA-dependent protein synthesis.

In placebo-controlled trials, the overall incidence of adverse events with telmisartan was similar to that with placebo. The occurrence of adverse events was not related to dose, and was also unrelated to the patient's gender, age, and race. The pharmacological effects of telmisartan include lowering blood pressure, and possible adverse reactions include back pain, chest pain, flu-like symptoms, infection symptoms, dizziness, abdominal pain, diarrhea, indigestion, gastrointestinal dysfunction, joint pain, leg cramps or leg pain, myalgia, etc. The laboratory found occasional decreases in hemoglobin or increases in uric acid, but increases in blood creatinine or liver enzymes were similar to or lower than placebo.
