Study Notes
Differentiating Acute Angle Closure and CN3 Palsy
- Pilocarpine is used to differentiate between acute angle closure glaucoma and oculomotor nerve palsy (CN3 palsy) due to its ability to constrict the pupil.
Reversible Acetylcholinesterase Inhibitors
- Atropine is ineffective against reversible acetylcholinesterase inhibitors, such as pyridostigmine, as it does not counteract the effects of these agents.
Treatment of Myasthenia Gravis
- Pyridostigmine is the primary drug used for the treatment of myasthenia gravis, functioning as a reversible acetylcholinesterase inhibitor to improve neuromuscular transmission.
Evaluating Limb Strength
- Edrophonium (Tensilon) is administered to evaluate limb strength in suspected myasthenia gravis, providing a temporary increase in strength that helps in diagnosis.
Drug Worsening Myasthenia Gravis
- Aminoglycosides are known to worsen symptoms of myasthenia gravis due to their neuromuscular blockade effects.
