Ciprofloxacin Hydrochloride Tablets generally maintain an effective therapeutic concentration in the body for about 24 hours, but this varies from person to person and is related to factors such as individual constitution. Ciprofloxacin Hydrochloride Tablets are used for the treatment of genitourinary infections, respiratory tract infections and other diseases caused by sensitive bacterial sensations. After oral administration of the drug, 40% to 50% of the administered dose is excreted in its original form via the kidneys in 24 hours, and about 15% is excreted as metabolites. At this point, the drug is unable to maintain adequate blood concentrations, and then it begins to slowly become ineffective. Therefore, the drug generally maintains an effective therapeutic concentration in the body for about 24 hours. However, since the metabolism rate of the drug is different for each person, the above data can only be used as a reference, and there is no way to judge the specificity of each individual. Some patients may experience adverse reactions such as diarrhea, nausea and vomiting after using the drug. Ciprofloxacin Hydrochloride Tablets are contraindicated in people who are allergic to it to prevent allergic symptoms such as generalized itching and shock. The effective concentration of ciprofloxacin hydrochloride in the body usually stays for about 48 hours, and patients should take the medicine as prescribed by the doctor to avoid blind use of the drug.
