Isopto Eserine

Isopto Eserine Uses, Dosage, Side Effects, Food Interaction and all others data.

A cholinesterase inhibitor that is rapidly absorbed through membranes. It can be applied topically to the conjunctiva. It also can cross the blood-brain barrier and is used when central nervous system effects are desired, as in the treatment of severe anticholinergic toxicity.

Isopto Eserine is a parasympathomimetic, specifically, a reversible cholinesterase inhibitor which effectively increases the concentration of acetylcholine at the sites of cholinergic transmission. Isopto Eserine is used to treat glaucoma. Because it crosses the blood-brain barrier, it is also used to treat the central nervous system effects of atropine overdose and other anticholinergic drug overdoses. Isopto Eserine can reverse both central and peripheral anticholinergia.

Uses

Isopto Eserine is a cholinesterase inhibitor used to treat glaucoma and anticholinergic toxicity.

For the treatment of glaucoma, and in the treatment of severe anticholinergic toxicity.

Isopto Eserine is also used to associated treatment for these conditions: Anticholinergic Syndrome

How Isopto Eserine works

Isopto Eserine inhibits acetylcholinesterase, the enzyme responsible for the breakdown of used acetylcholine. By interfering with the metabolism of acetylcholine, physostigmine indirectly stimulates both nicotinic and muscarinic receptors due to the consequential increase in available acetylcholine at the synapse.

Toxicity

Side effects include increased sweating, loss of bladder control, muscle weakness, nausea, vomiting, diarrhea, or stomach cramps or pain, shortness of breath, tightness in chest, or wheezing, slow or irregular heartbeat, unusual tiredness or weakness, watering of mouth, blurred vision or change in near or distant vision, and eye pain.

FAQ

What is Isopto Eserine used for?

Isopto Eserine use in the treatment of glaucoma and the treatment of anticholinergic toxicity. It is useful to treat the central nervous system effects of anticholinergic toxicity due to its ability to cross the blood-brain barrier.

How safe is Isopto Eserine?

Isopto Eserine alone was safely used to treat 74.3% (n = 142) of patients in our cohort.Isopto Eserine may be considered as a safe first-line therapy to treat anticholinergic delirium.

How does Isopto Eserine work?

Isopto Eserine work by interfering with the metabolism of acetylcholine.

What are the common side effects of Isopto Eserine?

Common side effects of Isopto Eserine are include:

  • excessive saliva production.
  • excessive sweating.
  • nausea.
  • vomiting.
  • diarrhea.
  • stomach cramps.

Is Isopto Eserine safe during pregnancy?

No studies have been done in animals, and no well-controlled studies have been done in pregnant women.Isopto Eserine should be given to a pregnant woman only if clearly needed.

Is Isopto Eserine safe during breastfeeding?

Benefit should outweigh risk.Because of its low molecular weight, excretion into breast milk is probable.

How long does Isopto Eserine take to work?

Topical administration of Isopto Eserine produces an IOP reduction that begins in 10–30 minutes, reaches a maximum in 1–2 hours, and lasts for 4–6 hours.

How is Isopto Eserine taken?

Isopto Eserine is injected into a muscle or into a vein through an IV. A healthcare provider will give you this injection. When injected into a vein, physostigmine must be given slowly.

When do I give Isopto Eserine?

Isopto Eserine treatment may be indicated for patients with moderate to severe anticholinergic poisoning with evidence of both peripheral and central toxicity.

Can I take Isopto Eserine for a long time?

Patients are not likely to require further Isopto Eserine redosing more than 6.5 h from their first dose.

Who should not take Isopto Eserine?

In an emergency situation it may not be possible to tell your caregivers about your health conditions. Make sure any doctor caring for you afterward knows you have received physostigmine.

What happens if I miss a dose?

Apply the missed dose as soon as you remember. However, if it is almost time for the next regularly scheduled dose, skip the missed dose and apply the next one as directed. Do not use a double dose of this medication.

What happens if I overdose of Isopto Eserine?

Flush the eye with water and seek emergency medical attention if an overdose is suspected.Symptoms of a physostigmine ophthalmic overdose may include sweating, nausea, vomiting, diarrhea, watering mouth, tearing eyes, fainting, difficulty breathing, and an irregular heartbeat.

Does Isopto Eserine cause bronchoconstriction?

Patients with asthma should not be given physostigmine because it can worsen bronchoconstriction.Isopto Eserine can alter insulin requirements so it also should not be used in patients with diabetes mellitus.

How long does Isopto Eserine stay in my system?

Because the clinical duration of action of Isopto Eserine is short (20 to 90 minutes) compared with that of antipsychotic agents, resolution of the anticholinergic stigmata after Isopto Eserine administration should not alter patient disposition.

What does Isopto Eserine do to muscles?

Isopto Eserine affects chemicals in the body that control the signals sent from the nervous system to the muscles to activate muscle movement.

How do you administer Isopto Eserine?

Administer 0.5 – 1 mg IV as a slow push over 5 minutes and repeat every 10 minutes until the desired clinical effects are observed. It is rare for more than 4 mg to be required. The duration of action is much shorter than most cases of anticholinergic delirium.

*** Taking medicines without doctor's advice can cause long-term problems.
