Overview

What is Bloxiverz?

Neostigmine methylsulfate, a cholinesterase inhibitor, is (-hydroxyphenyl) trimethylammonium methylsulfate dimethylcarbamate. The structural formula is:

Neostigmine methylsulfate is a white crystalline powder and is very soluble in water and soluble in alcohol. BLOXIVERZ is a sterile, nonpyrogenic solution intended for intravenous use.

Each mL of the 1 mg/mL strength contains neostigmine methylsulfate 1 mg, phenol 4.5 mg (used as preservative), and sodium acetate trihydrate 0.2 mg, in water for injection. The pH is adjusted, when necessary, with acetic acid/sodium hydroxide to achieve a value of 5.5.

Injection: 1 mg/mL in 10 mL multiple-dose vials ()

What should I talk to my health care provider before I take Bloxiverz?

How should I use Bloxiverz?

BLOXIVERZ is a cholinesterase inhibitor indicated for the reversal of the effects of non-depolarizing neuromuscular blocking agents after surgery.

BLOXIVERZ should be administered by trained healthcare providers familiar with the use, actions, characteristics, and complications of neuromuscular blocking agents (NMBA) and neuromuscular block reversal agents. Doses of BLOXIVERZ should be individualized, and a peripheral nerve stimulator should be used to determine the time of initiation of BLOXIVERZ and should be used to determine the need for additional doses.

BLOXIVERZ is for intravenous use only and should be injected slowly over a period of at least 1 minute. The BLOXIVERZ dosage is weight-based .

Prior to BLOXIVERZ administration and until complete recovery of normal ventilation, the patient should be well ventilated and a patent airway maintained. Satisfactory recovery should be judged by adequacy of skeletal muscle tone and respiratory measurements in addition to the response to peripheral nerve stimulation.

An anticholinergic agent, e.g., atropine sulfate or glycopyrrolate, should be administered prior to or concomitantly with BLOXIVERZ

What might happen if I take too much Bloxiverz?

Muscarinic symptoms (nausea, vomiting, diarrhea, sweating, increased bronchial and salivary secretions, and bradycardia) may appear with overdosage of BLOXIVERZ (cholinergic crisis), but may be managed by the use of additional atropine or glycopyrrolate. The possibility of iatrogenic overdose can be lessened by carefully monitoring the muscle twitch response to peripheral nerve stimulation. Should overdosage occur, ventilation should be supported by artificial means until the adequacy of spontaneous respiration is assured, and cardiac function should be monitored.

Overdosage of BLOXIVERZ can cause cholinergic crisis, which is characterized by increasing muscle weakness, and through involvement of the muscles of respiration, may result in death. Myasthenic crisis, due to an increase in the severity of the disease, is also accompanied by extreme muscle weakness and may be difficult to distinguish from cholinergic crisis on a symptomatic basis. However, such differentiation is extremely important because increases in the dose of BLOXIVERZ or other drugs in this class, in the presence of cholinergic crisis or of a refractory or “insensitive” state, could have grave consequences. The two types of crises may be differentiated by the use of edrophonium chloride as well as by clinical judgment.

Treatment of the two conditions differs radically. Whereas the presence of myasthenic crisis requires more intensive anticholinesterase therapy, cholinergic crisis calls for the prompt withdrawal of all drugs of this type. The immediate use of atropine in cholinergic crisis is also recommended. Atropine may also be used to lessen gastrointestinal side effects or other muscarinic reactions; but such use, by masking signs of overdosage, can lead to inadvertent induction of cholinergic crisis.

Clinical Information

Chemical Structure

No Image found
Clinical Pharmacology

Neostigmine methylsulfate is a competitive cholinesterase inhibitor. By reducing the breakdown of acetylcholine, neostigmine methylsulfate induces an increase in acetylcholine in the synaptic cleft which competes for the same binding site as nondepolarizing neuromuscular blocking agents, and reverses the neuromuscular blockade.

Non-Clinical Toxicology
BLOXIVERZ is contraindicated in patients with:

Diphenhydramine hydrochloride has additive effects with alcohol and other CNS depressants (hypnotics, sedatives, tranquilizers, etc.)

MAO inhibitors prolong and intensify the anticholinergic (drying) effects of antihistamines.

Neostigmine has been associated with bradycardia. Atropine sulfate or glycopyrrolate should be administered prior to BLOXIVERZ to lessen the risk of bradycardia .
