Nitrofurantoin is an antibacterial agent, which has a wide range of antibacterial activities against common aerobic gram - positive and gram - negative pathogens. It exists in the form of yellow to light yellow crystalline powder, sparingly soluble in water, slightly soluble in ethanol, and insoluble in chloroform and ether. The molecular formula of Nitrofurantoin is C₈H₇N₃O₅, and its molecular weight is 237.16.
Nitrofurantoin is mainly used in the medical field for the treatment and prophylaxis of urinary tract infections caused by susceptible bacteria. It can effectively inhibit the growth and reproduction of bacteria such as Escherichia coli, Enterococcus faecalis, Staphylococcus saprophyticus, etc. Its antibacterial mechanism is to interfere with the bacterial enzyme system, thereby affecting the synthesis of bacterial proteins, DNA, RNA and cell wall.
In addition to medical applications, in the research field, Nitrofurantoin can also be used as a research tool for antibacterial mechanism research, helping scientists to explore the interaction between bacteria and drugs and develop more effective antibacterial strategies.
The use of Nitrofurantoin should be carried out under the guidance of a professional doctor. Usually, it is taken orally. For the treatment of urinary tract infections in adults, the general dose is 50 - 100 mg each time, taken 4 times a day, and the course of treatment is usually 7 days. For prophylaxis, a lower dose of 50 - 100 mg can be taken once a day at bedtime.
When taking Nitrofurantoin, it should be taken with food to increase its absorption and reduce gastrointestinal irritation. Do not chew or crush the tablets, and swallow them whole with a full glass of water. If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue your regular dosing schedule.
Case 1: A 32 - year - old female patient had symptoms such as frequent urination, urgent urination, and painful urination. After urine examination, it was diagnosed as a urinary tract infection caused by Escherichia coli. The doctor prescribed Nitrofurantoin at a dose of 100 mg, 4 times a day. After taking the drug for 3 days, the patient's symptoms were significantly relieved. After a 7 - day course of treatment, the urine test results returned to normal, and the infection was completely cured.
Case 2: A 65 - year - old male patient with a history of recurrent urinary tract infections. In order to prevent recurrent infections, the doctor recommended taking 50 mg of Nitrofurantoin once a day at bedtime. After continuous use for 6 months, the patient's frequency of urinary tract infections was significantly reduced from 3 - 4 times a year to once a year, effectively improving the patient's quality of life.
