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 ...
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 ...
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 has good activity against Gram-positive and Gram-negative bacteria, but is ototoxic. Its use is thus restricted to the oral treatment of intestinal infections. [22] Neomycin B is composed of four linked moieties: D-neosamine, 2-deoxystreptamine (2-DOS), D-ribose, and L-neosamine. [citation needed]
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.

Nalidixic acid (tradenames Nevigramon, NegGram, Wintomylon and WIN 18,320) is the first of the synthetic quinolone antibiotics.. In a technical sense, it is a naphthyridone, not a quinolone: its ring structure is a 1,8-naphthyridine nucleus that contains two nitrogen atoms, unlike quinoline, which has a single nitrogen atom.
