A parasympathomimetic drug, sometimes called a cholinomimetic drug [1] or cholinergic receptor stimulating agent, [2] is a substance that stimulates the parasympathetic nervous system (PSNS).
Physostigmine, an acetylcholinesterase inhibitor, can be used to treat glaucoma and delayed gastric emptying.Because it enhances the transmission of acetylcholine signals in the brain and can cross the blood–brain barrier, physostigmine salicylate is used to treat anticholinergic poisoning (that is, poisoning by substances that interfere with the transmission of acetylcholine signaling, such ...
Agents in common clinical use include: [1] [2] Prostaglandin analogs; Parasympathomimetic (miotic) agents, including cholinergic and anticholinesterase agents; Carbonic anhydrase inhibitors (oral and topical)
Neomycin belongs to the aminoglycoside class of antibiotics and fights against Gram positive and gram negative bacteria. The antibiotic is often used to prevent risk of bacterial infections. [22] Aminoglycosides work by binding to bacterial RNA and changing the ability to produce proteins while exerting little to no effect on DNA. Thus ...
Erythromycin.The macrolide ring is the lactone (cyclic ester) at upper left. Clarithromycin Roxithromycin. Macrolides are a class of mostly natural products with a large macrocyclic lactone ring to which one or more deoxy sugars, usually cladinose and desosamine, may be attached.
For many Gram-negative bacteria, DNA gyrase is the target, whereas topoisomerase IV is the target for many Gram-positive bacteria. [citation needed] Eukaryotic cells are not believed to contain DNA gyrase or topoisomerase IV. However, debate exists concerning whether the quinolones still have such an adverse effect on the DNA of healthy cells.
Chloroxylenol, also known as para-chloro-meta-xylenol (PCMX), is a chlorine substituted phenol with a white to off-white appearance and a phenolic odor.. The discovery of chloroxylenol was the result of efforts to produce improved antiseptics that began at the end of the 1800s, when scientists gradually realized that more substituted and more lipophilic phenols are less toxic, less irritant ...
Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside . [1] [2] The term can also refer more generally to any organic molecule that contains amino sugar substructures.
