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.
The present invention contemplates a novel oral dosage form for the intestinal delivery of ceftriaxone sodium. The oral dosage form inhibits enteric degradation of the therapeutic compound by encapsulation within an inner core region and having an outer shell, preventing its dissolution until reaching the small intestine.
