6. Which for at and can cause drow • Inform patients that most of the centrally acting muscle relaxants for acute spasms are usually taken for no longer than 3 weeks. • Teach patients to avoid alcohol and CNS depressants. If muscle relaxants are taken with these drugs, CNS depres- sion may be intensified Evaluation uate the effectiveness of the muscle relaxant, and de ermine whether the patient's muscular pain or spasm have decreased or disappeared. a.

Answer 1

Pyridostigmine helps patients in myasthenia gravis by preventing the breakdown of acetylcholine chemucal in our body. Acetylcholine is required for normal function of muscle.

Side effects:

Upset stomach, diarhoea, vomiting

pale skin, drooling

muscle weakness etc

Adverse effects:

muscle cramps

twitching etc

Delayed intake of drug:

Trouble talking

fatigue

walking problem

drooping of eyelids

Overdosing :

passing out

trouble breathing

mental changes

heartbeat changes

inability to move etc

Drug inetractions:

Coticosteroids

Anticholinergics

beta blockers

Difference between myasthenia crisis & cholinergic crisis:

Cholinergic crisis is when excess acetyl choline is present in body leading to excessive stimulation of neuromuscular junction.

Myasthenia crisis indictes excesse breakdown of acetyl choline resulting in diminished neuro muscular coordination.
