The unique domain of otolaryngologists is the treatment of ear disorders. They are trained in both the medical and surgical treatment of hearing loss, ear infections, balance disorders, ear noise (tinnitus), and some cranial nerve disorders.
It has a calculated molecular weight of 661.60 and the following structural formula: Ceftriaxone for injection is a white to yellowish-orange crystalline powder which is readily soluble in water, sparingly soluble in methanol and very slightly soluble in ethanol. The pH of a 1% aqueous solution is approximately 6.7. The color of ceftriaxone for injection solutions ranges from light yellow to amber, depending on the length of storage, concentration and diluent used. Ceftriaxone for injection contains approximately 83 mg (3.6 mEq) of sodium per gram of ceftriaxone activity.
Precipitation of ceftriaxone-calcium can also occur when ceftriaxone is mixed with calcium-containing solutions in the same IV administration line. Therefore, ceftriaxone and calcium-containing solutions must not be mixed or administered simultaneously (see sections 4.3, 4.4 and 6.2).xcretion: Ceftriaxone is eliminated mainly as unchanged drug, approximately 60% of the dose being excreted in the urine (almost exclusively by glomerular filtration) and the remainder via the biliary and intestinal tracts. The total plasma clearance is 10-22 ml/min.
