Here is another example of elimination in pharmacy.
Curare is a type of drug called a muscle relaxant. It acts
by blocking nerve impulses at the neuromuscular junction thus causing the muscle
to relax. Such drugs are very useful during surgery when the patient needs to be
immobilised. The downside to curare is that it takes a long time for the effect
to wear off after surgery and can cause respiratory depression. The effect
would only wear off after the drug gets metabolised – that is it gets changed
in the body – to a not active form. (Metabolism is a process where a drug is
changed to another form when it enters our body).
Curare is a drug used to relax the muscles during a surgery. Its effect is slow to wear off after surgery and may cause inconvenience such as breathing suppression. |
Newer muscle relaxants such as atracurium have been developed
that has a built-in functional group that allows the drug to rapidly metabolised
or changed into an inactive form. One such change involves an elimination reaction of the quarternary ammonium group of the drug
(Refer to notes on elimination of amines).
