| Demecarium bromide | Demecarium bromid is an indirect-acting parasympathomimetic agent that is used to treat glaucoma. It is a cholinesterase inhibitor or an anticholinesterase. Cholinesterase inhibitors prolong the effect of acetylcholine, which is released at the neuroeffector junction of parasympathetic postganglion nerves, by inactivating the cholinesterases that break it down. Demecarium inactivates both pseudocholinesterase and acetylcholinesterase. In the eye, this causes constriction of the iris sphincter muscle (causing miosis) and the ciliary muscle. The outflow of the aqueous humor is facilitated, which leads to a reduction in intraocular pressure. Pharmacology: Demecarium is a long-acting cholinesterase inhibitor and potent miotic. Because of its toxicity, it should be reserved for use in patients with open-angle glaucoma or other chronic glaucomas not satisfactorily controlled with the short-acting miotics and other agents. Application of demecarium to the eye produces intense miosis and ciliary muscle contraction due to inhibition of cholinesterase, allowing acetylcholine to accumulate at sites of cholinergic transmission. These effects are accompanied by increased capillary permeability of the ciliary body and iris, increased permeability of the blood-aqueous barrier, and vasodilation. Myopia may be induced or, if present, may be augmented by the increased refractive power of the lens that results from the accommodative effect of the drug. Mechanism of action: Demecarium is an indirect-acting parasympathomimetic agent, also known as a cholinesterase inhibitor and anticholinesterase. Cholinesterase inhibitors prolong the effect of acetylcholine, which is released at the neuroeffector junction of parasympathetic postganglion nerves, by inactivating the cholinesterases that break it down. Demecarium inactivates both pseudocholinesterase and acetylcholinesterase. In the eye, this causes constriction of the iris sphincter muscle (causing miosis) and the ciliary muscle (affecting the accommodation reflex and causing a spasm of the focus to near vision). The outflow of the aqueous humor is facilitated, which leads to a reduction in intraocular pressure. Of the two actions, the effect on the accommodation reflex is the more transient and generally disappears before termination of the miosis. Drug type: Approved. Small Molecule.

| Demeclocycline | A tetracycline analog having a 7-chloro and a 6-methyl. Because it is excreted more slowly than tetracycline, it maintains effective blood levels for longer periods of time. (PubChem) Pharmacology: Demeclocycline is a tetracycline antibiotic active against the following microorganisms: Rickettsiae (Rocky Mountain spotted fever, typhus fever and the typhus group, Q fever, rickettsial pox, tick fevers), Mycoplasma pneumoniae (PPLO, Eaton agent), agents of psittacosis and ornithosis, agents of lymphogranulomavenereum and granuloma inguinale, the spirochetal agent of relapsing fever (Borrelia recurrentis), Haemophilus ducreyi (chancroid), Yersinia pestis, Pasteurella pestis and Pasteurella tularensis, Bartonella bacilliformis, Bacteroides species, Vibrio comma and Vibrio fetus, and Brucella species (in conjunction with streptomycin). Demeclocycline inhibits cell growth by inhibiting translation. Demeclocycline is lipophilic and can easily pass through the cell membrane or passively diffuses through porin channels in the bacterial membrane. Demeclocycline is bacteriostatic (it impairs bacterial growth but does not kill bacteria directly). Because it is excreted more slowly than tetracycline, it maintains effective blood levels for longer periods of time. Mechanism of action: Demeclocycline inhibits cell growth by inhibiting translation. It binds (reversibly) to the 30S and 50S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome, which impairs protein synthesis by bacteria. The binding is reversible in nature. The use in SIADH actually relies on a side-effect of tetracycline antibiotics; many may cause diabetes insipidus (dehydration due to the inability to concentrate urine). It is not completely understood why demeclocycline impairs the action of antidiuretic hormone, but it is thought that it blocks the binding of the hormone to its receptor. Drug type: Approved.

| Demyelinating Autoimmune Disease | Conditions characterized by loss or dysfunction of myelin (see MYELIN SHEATH) in the brain, spinal cord, or optic nerves secondary to autoimmune mediated processes. This may take the form of a humoral or cellular immune response directed toward myelin or OLIGODENDROGLIA associated autoantigens (MeSH). | ILX:0103018 | 3 | scicrunch | 06/18/2018 | scicrunch | term | 12/08/2016 | 0 | NeuroLex | NeuroLex |
