Tobramycin/dexamethasone ( INNs , trade name Tobradex , Tobrason in Jordan  ) is a prescription medication in the form of eye drops and eye ointment , marketed by Alcon . The active ingredients are tobramycin % (an antibiotic ) and dexamethasone % (a corticosteroid ). It is prescribed for a wide spectrum of bacterial eye infections. Tobradex can also be used to clear or contract styes that are also found in the eye. It is prescribed for the treatment of pink eye in combination with bacterial infections. Because it contains a steroid, careful use with gradual reduction of doses is required.
In cerebral edema , Dexamethasone sodium phosphate injection is generally administered initially in a dosage of 10 mg intravenously followed by 4 mg every six hours intramuscularly until the symptoms of cerebral edema subside. Response is usually noted within 12 to 24 hours and dosage may be reduced after two to four days and gradually discontinued over a period of five to seven days. For palliative management of patients with recurrent or inoperable brain tumors, maintenance therapy with either Dexamethasone sodium phosphate injection or Dexamethasone tablets in a dosage of 2 mg two or three times daily may be effective.
