    Study Notes

    Nervous System Disorders - Pharmacological Treatment

    • Myasthenia Gravis:

      • Treated with acetylcholinesterase inhibitors.
      • Prototype drug: Pyridostigmine.
      • Action: Increases acetylcholine levels at the synapse, improving muscle function.
      • Adverse effects: Increased secretions, cardiovascular effects.
      • Contraindications: Renal and hepatic impairment, asthma, CV disease.

    • Alzheimer's Disease:

      • Characterized by cholinergic deficiency in the brain.
      • Treated with cholinesterase inhibitors.
      • Prototype drugs: Donepezil (Aricept), Rivastigmine (Exelon).
      • Action: Slows the progression of the disease by increasing acetylcholine levels.
      • Adverse effects: Headache, dizziness, GI issues, depression.
      • Contraindications: Lung disease, heart disease.

    N-methyl-d-aspartate Receptor Antagonist

    • Prototype: Memantine (Namenda).
    • Action: Slows the progression of moderate to severe Alzheimer's disease by antagonizing the NMDA receptor.
    • Uses: Slows progression of moderate to severe Alzheimer's disease.
    • Contraindications: Renal failure.

    Urinary Retention

    • Causes: Nerve damage, diabetes, enlarged prostate, pregnancy, neurologic disorders (multiple sclerosis, Parkinson's), surgery.
    • Cholinergic Agonist: Bethanechol Chloride (Urecholine).
      • Action: Acts like acetylcholine, increasing urinary and GI muscle tone.
      • Use: Acute post-operative urinary retention, neurogenic atony.
      • Adverse effects: Heart block, orthostatic hypotension, GI issues, urinary urgency.
      • Contraindications: Bladder neck surgery.

    Drug Therapy for Parkinson's Disease

    • Parkinson's Disease: A chronic, progressive disorder affecting movement, characterized by resting tremor, bradykinesia, rigidity, postural instability, and shuffling gait.
    • Dopamine Receptor Agonists: Levodopa-carbidopa (Sinemet), Amantadine, Pramipexole, Ropinirole.
      • Action: Increases dopamine in the synapse.
      • Uses: Parkinson's Disease, Restless Leg Syndrome.

    Catechol-O-Methyltransferase Inhibitors

    • Prototype: Tolcapone.
    • Action: Increases dopamine levels in the brain by inhibiting levodopa metabolism.
    • Use: Used in conjunction with levodopa-carbidopa to treat Parkinson's.
    • Adverse Effects: CNS, CV, GI, respiratory system issues.
    • Contraindications: Liver disease.

    Anticholinergics

    • Action: Antispasmodic and antisecretory action
    • Use: Idiopathic Parkinson's, patients intolerant of levodopa, extrapyramidal reactions
    • Examples: Atropine, Benztropine, Dicyclomine, Oxybutynin
    • Adverse effects: Anticholinergic effects (e.g., blurred vision, dry mouth, constipation)
    • Contraindications: Glaucoma, myasthenia gravis, GI/GU obstruction, prostatic hypertrophy

    Additional Medications/Uses

    • Gastrointestinal Anticholinergics (Dicyclomine): GI smooth muscle relaxant, irritable bowel syndrome.
    • Urinary Antispasmodics (Oxybutynin): Relaxes smooth muscle to treat bladder instability and incontinence.
