Perinatal hypoxia can lead to a number of serious medical conditions, such as Hypoxic Ischemic Encephalopathy (HIE) and brain injuries related to birth asphyxia. All three of these injuries are serious brain injuries that may lead to paralysis and severe brain damage.
1 A substance (or ligand) is cholinergic if it is capable of producing, altering, or releasing acetylcholine (indirect-acting) or mimicking its behaviour at one or more of the body's acetylcholine receptor types (direct-acting).2  Such mimics are called parasympathomimetic drugs or cholinomimetic drugs.n general, the word choline refers to the various quaternary ammonium salts containing the N,N,N-trimethylethanolammonium cation. Found in most animal tissues, choline is a primary component of the neurotransmitter acetylcholine and functions with inositol as a basic constituent of lecithin.
A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes. Anticholinergic bronchodilators (or muscarinic receptor antagonists) block the parasympathetic nerve reflexes that cause the airways to constrict, so allow the air passages to remain open. Muscarinic receptor antagonists bind to muscarinic receptors and inhibit acetylcholine mediated bronchospasm. Anticholinergic bronchodilators are used more to treat chronic obstructive pulmonary disease than to treat asthma.
