Ceftriaxone, active ingredient-beta-lactam antibiotic, belonging to the category of third-generation cephalosporin. It is characterized by a wide range of action, both on gram -positive and gram -negative bacteria, even when they are resistant to antibiotic therapy.
Bactericidal activity is expressed through the inhibiting of transpeptidase - an enzyme involved in the formation of stitching between peptidoglycans molecules and in the structure of the bacterial wall, which determines the lysis of microorganisms and osmotic shock.
Clinical effectiveness of ceftriaxone
Belonging to the methoxymin group, gives Ceftriaxone natural resistance to bacterial beta-lactamases, its antibiotic activity remains, also for species resistant to penicillin.
Staphylococci, streptococci, E. coli, hemophilic infection, Klebsiella, Proteus of bacteria, Neisseria and enterobacteria - microorganisms, over which effectiveness is proved in a tube and in natural conditions.
The impossibility of absorption of ceftriaxone through the gastrointestinal tract makes it necessary to take the drug intramuscularly or intravenously, which allows maintaining very high bioavailability and prolonged therapeutic effect for about 8 hours.

The results of the analysis of the effect of the drug demonstrated high effectiveness and safety of ceftriaxone, taken in the daily doses of 250 mg in the treatment of gonorrhea, even in patients with complications.
The study of 116 patients with syphilis, 80% of HIV - positive, confirms that the use of the drug is effective in the treatment of primary syphilis, and in some cases, also secondary neurological and ophthalmological syphilis.
A pharmacological study aimed at determining the optimal dosage of ceftriaxon in small patients showed not very good results. Unfortunately, potential side effects greatly limit the use of this antibiotic, although it is especially effective in neonatal therapy.
Method of use and dosage of ceftriaxone
- Powder and solvent for ceftriaxone 250 mg for 2 ml of solution.
- Powder and solvent for ceftriaxone 500 mg for 2 ml of solution.
- Powder and solvent for ceftriaxone 1 g for 3.5 ml of solution.
Although the standard dose for adults requires 1 g of ceftriaxone per day, the doctor must determine the suitable therapeutic scheme based on the physical and pathological characteristics of the patient, the severity of the clinical situation and therapeutic goals to achieve.
Adaptation of doses used is necessary for pediatric and geriatric (elderly) patients, or suffering from kidney diseases. Before taking ceftriaxone, it would be advisable to carefully check the chemical and physical properties of the drug, avoiding its use in the presence of precipitation.

Warning when taking ceftriaxone
Given the potential side effects and selectivity of therapeutic indications provided for use, it would be advisable for the doctor to carefully assess the patient's health, making sure:
- In the absence of previous reactions of supersensitivity to antibiotics and lidocaine.
- In the absence of conditions incompatible with therapy with ceftriaxone.
- In the correctness of the prescription.
- In the analysis of renal and liver functions.
In addition, periodic monitoring of the patient’s health status is necessary to avoid the possible occurrence of adverse reactions.
In this regard, the patient must immediately inform his doctor, after any undesirable effects occur and consider the suspension of therapy.

Long -term antibiotic therapy, over time, in addition to stimulating the occurrence of resistant microbial strains, can seriously change the intestinal microflora, contributing to the occurrence of adverse consequences and violating the absorption of other active ingredients.
If ceftriaxone is used for a long period, a systematic blood test may be needed. An antibiotic can affect the results of urine tests associated with sugar, and a blood test, known as the Cumbs test. It is important to consider the issue of reducing the effectiveness of contraception of oral contraceptives taken during antibacterial therapy.
Pregnancy and lactation while taking ceftriaxone
Ceftriaxone during pregnancy and the next period of breastfeeding should be prescribed with particular caution, and only in cases where it is therapeutically necessary.
These restrictions are justified by the lack of studies that can characterize the safety of this antibiotic for the health of the fetus.
Ceftriaxone: interaction with other drugs
To avoid unpleasant side effects, sometimes even clinically significant, it would be advisable to avoid dissolution of the powder using calcium -containing solvents, given the high tendency to the formation of precipitation.
Studies have shown the synergistic effect between aminoglycosides and ceftriaxone, in combating bacterial growth, although they cannot be administered simultaneously due to physical incompatibility.
Contraindications for taking ceftriaxone
