Neuromuscular blocks

C14H30CI2N2O4. White powder prepared from dimethylaminoethanol and succinyl chloride, followed by methylation. Neuromuscular blocking agent used to relax skeletal muscles during certain types of surgical operation. 

It is important to use these drag with caution in patients with a history of gastrointestinal disorders, renal disease, or liver impairment. The neuromuscular blocking action of die lincosamides poses a danger to patients widi myasthenia gravis (an autoimmune disease manifested by extreme weakness and exhaustion of die muscles). 

When kaolin or aluminum is administered widi die lincosamides, die absorption of the lincosamide is decreased. When the lincosamides are administered with the neuromuscular blocking drag (drag diat are used as adjuncts to anesthetic drag diat cause paralysis of the respiratory system) die action of die neuromuscular blocking drug is enhanced, possibly leading to severe and profound respiratory depression.

Contrary to other elicitors of non-immune anaphylactic reactions (radiocontrast media, neuromuscular blocking agents, non-steroidal anti-inflammatory drugs (NSAIDs)) where there are at least hypothetical concepts regarding the pathomecha-nism of these reactions via increased mediator release (e.g. histamine release, shift in arachidonic acid metabolism from prostaglandins towards leukotrienes, etc.) [26], there is almost no literature regarding the pathomechanism of these reactions after LA application. 

Online detection using 4H nuclear magnetic resonance (NMR) is a detection mode that has become increasingly practical. In a recent application, cell culture supernatant was monitored on-line with 1-dimensional NMR for trehalose, P-D-pyranose, P-D-furanose, succinate, acetate and uridine.33 In stopped-flow mode, column fractions can also be analyzed by 2-D NMR. Reaction products of the preparation of the neuromuscular blocking compound atracurium besylate were separated on chiral HPLC and detected by 4H NMR.34 Ten isomeric peaks were separated on a cellulose-based phase and identified by online NMR in stopped-flow mode.
