Cholinomimetic drugs have become the clinical standard for the treatment of patients with dementia of the Alzheimer type (DAT). Ne ostigmine is water soluble and cannot cross BBB but is highlt concentrated in the Ne uromuscular junction and hence used in treatment of Myasthenia gravis. Cholinomimetic drugs are used widely in ophthal-mology for the treatment of glaucoma and in diagnostic tests for drug supersesitivity resulting from parasympathetic denervation of the pupil (Thompson, 1975). 3. What is Cholinergic drugs • Acetylcholine is a neurotransmitter in the parasympathetic system. Indicate a cholinomimetic agent, which is related to direct-acting drugs: a) Edrophonium b) Physostigmine c) Carbachol d) Isoflurophate 007. Pilocarpine causes marked sweating, salivation and increases other secretions as well. It is taken by mouth. Neostigmine is the anticholinesterase agent of choice for treatment of paralytic ileus or urinary bladder atony. Cholinomimetic alkaloids → pilocarpine, muscarine. Subsequently, Renshaw et al (91) have studied the basal ganglia of depressed and control subjects, and noted an alteration in the metabolism of cytosolic choline compounds in the basal ganglia of depressives, particularly those responsive to fluoxetine. More research is needed in DAT patients to determine whether an analysis of hippocampal structure or function can reliably predict the outcome of treatment with cholinomimetic drugs. Myasthenia Gravis appears to be caused by the binding of anti-nicotinic receptor antibodies to the nicotinic cholinergic receptor. The global impact of Alzheimer’s disease (AD) continues to increase, and focused efforts are needed to address this immense public health challenge. Neostigmine, pyridostigmine and corticosteroids.
