Norepinephrine, also known as noradrenaline and sold under the brand name Levophed among others, is a medication used to treat people with very low blood pressure. [2] It is the typical medication used in sepsis if low blood pressure does not improve following intravenous fluids . [ 3 ]
The BNF for Children developed from the British National Formulary (BNF), which prior to 2005 had provided information on the treatment of children, with the doses largely determined by calculations based on the body weight of the child. The guidance was provided by pharmacists and doctors whose expertise was in the care of adults.
Drug titration is the process of adjusting the dose of a medication for the maximum benefit without adverse effects. [ 1 ] When a drug has a narrow therapeutic index , titration is especially important, because the range between the dose at which a drug is effective and the dose at which side effects occur is small.

The Surviving Sepsis Campaign guidelines recommend the very early management of the sepsis focusing on the hour-1 bundle. This includes use of Vasopressin 0.03 units/minute as add-on to norepinephrine (NE) with intent of either raising the mean arterial pressure or decreasing the norepinephrine dosage (i.e. de-catecholaminization).

In pharmacokinetics, the rate of infusion (or dosing rate) refers not just to the rate at which a drug is administered, but the desired rate at which a drug should be administered to achieve a steady state of a fixed dose which has been demonstrated to be therapeutically effective. Abbreviations include K in, [1] K 0, [2] or R 0.
Norepinephrine is synthesized from the amino acid tyrosine by a series of enzymatic steps in the adrenal medulla and postganglionic neurons of the sympathetic nervous system, while the norepinephrine that functions as a neurotransmitter in the brain is produced in the locus coeruleus, located in the pons of the brainstem.

Intraosseous infusion (IO) is the process of injecting medication, fluids, or blood products directly into the bone marrow; [1] this provides a non-collapsible entry point into the systemic venous system. [2] The intraosseous infusion technique is used to provide fluids and medication when intravenous access is not
Many charts derive their data from studies conducted on opioid-naive patients. Patients with chronic (rather than acute) pain may respond to analgesia differently. Repeated administration of a medication is also different from single dosing, as many drugs have active metabolites that can build up in the body. [ 6 ]
