Study Notes
Opioid Analgesics
- Example medications include Codeine (Solpadeine), Morphine (Sevredol), Oxycodone (OxyNorm), Fentanyl (Durogesic).
- Mechanism of action involves binding to opioid receptors in the brain and spinal cord, inhibiting pain signals and altering pain perception.
- Primarily used for treating moderate to severe pain, including postoperative and cancer-related discomfort.
- Notable side effects: constipation, nausea, vomiting, drowsiness, risk of addiction, and respiratory depression at high doses.
COX-2 Inhibitors
- Medications include Celecoxib (Celebrex) and Etoricoxib (Arcoxia).
- Function by selectively inhibiting the COX-2 enzyme, reducing pain and inflammation with fewer gastrointestinal side effects relative to traditional NSAIDs.
- Indicated for conditions such as arthritis, postoperative pain, and chronic pain syndromes like osteoarthritis and rheumatoid arthritis.
- Side effects include increased risk of heart attack and stroke, along with potential kidney damage.
Anticonvulsants
- Commonly prescribed drugs are Gabapentin (Neurontin) and Pregabalin (Lyrica).
- These drugs stabilize electrical nerve activity in the brain, effective in managing neuropathic pain including diabetic neuropathy and fibromyalgia.
- Side effects may include dizziness, drowsiness, weight gain, blurred vision, and dry mouth.
Antidepressants (for Pain)
- Medications involved are Amitriptyline (Elavil), Duloxetine (Cymbalta), and Nortriptyline (Allegron).
- They work by inhibiting the reuptake of serotonin and norepinephrine, enhancing pain modulation in the central nervous system.
- Used primarily for chronic pain, particularly neuropathic pain and fibromyalgia.
- Possible side effects include drowsiness, dry mouth, constipation, weight gain, dizziness, and sexual dysfunction.
Local Anesthetics
- Examples include Lidocaine (Lidoderm, Versatis).
- Mechanism involves blocking sodium channels to prevent pain signal transmission along nerves.
- Indicated for localized pain relief during dental procedures, post-herpetic neuralgia, and minor injuries.
- Side effects can include skin irritation at the application site, numbness, and rare allergic reactions.
Muscle Relaxants
- Common drugs include Baclofen (Lioresal), Tizanidine (Sirdalud), and Diazepam (Valium).
- Act on the central nervous system or muscles to alleviate muscle spasms and the associated pain.
- Used for managing muscle spasms related to conditions such as back pain, multiple sclerosis, or spinal cord injuries.
- Side effects: drowsiness, dizziness, weakness, dry mouth, and risk of dependence with certain agents.
Corticosteroids
- Medications include Prednisolone (Deltacortril), Dexamethasone (Decadron), and Hydrocortisone (Solu-Cortef).
- These agents suppress inflammation by inhibiting components of the immune system.
- Used to mitigate severe inflammation from conditions like rheumatoid arthritis, sciatica, or severe back pain.
- Potential side effects: weight gain, elevated blood sugar levels, mood alterations, osteoporosis, and heightened infection risk.
Topical Analgesics
- Examples are Capsaicin (Zacin), Diclofenac Gel (Voltarol), and Lidocaine Patches (Versatis).
- Function by blocking pain signals or reducing inflammation directly at the application site.
- Useful for localized pain conditions, including arthritis and muscle pain.
- Side effects can include skin irritation, redness, burning sensations, and rare allergic reactions.
NMDA Receptor Antagonists
- Ketamine (Ketalar) serves as a key representative.
- Works by blocking NMDA receptors implicated in pain transmission and processing.
- Indicated for severe chronic pain, often utilized in hospital or palliative care settings.
- Side effects may comprise hallucinations, confusion, nausea, increased heart rate, and dizziness.
Opioid Antagonists (for Opioid-Induced Constipation)
- Naloxegol (Moventig) and Methylnaltrexone (Relistor) block opioid receptors in the gut to prevent constipation induced by opioid usage, without diminishing analgesic effects.
- Employed to alleviate opioid-related constipation.
- Side effects include diarrhea, abdominal pain, flatulence, and nausea.
Summary of Categories
- Non-Opioid Analgesics (NSAIDs): Alleviate pain and inflammation (e.g., for arthritis, injuries).
- Paracetamol (Acetaminophen): Effective for mild to moderate pain and fever relief.
- Opioid Analgesics: Target moderate to severe pain but carry risks of addiction and respiratory issues.
- COX-2 Inhibitors: NSAIDs with reduced gastrointestinal side effects, used in arthritis and chronic pain management.
- Anticonvulsants: Target neuropathic pain and fibromyalgia treatment.
- Antidepressants (for pain): Address chronic and nerve pain, even in non-depressed patients.
- Local Anesthetics: Provide localized relief for dental and minor procedures.
Parkinson's Category Overview
Dopamine Precursors
- Levodopa/Carbidopa (Sinemet), Levodopa/Benserazide (Madopar) convert to dopamine in the brain.
- Effective for motor symptoms like tremors and stiffness in Parkinson's disease.
- Side effects include nausea, vomiting, dizziness, low blood pressure, dyskinesia, and confusion.
Dopamine Agonists
- Medications include Pramipexole (Mirapexin), Ropinirole (Requip), and Rotigotine (Neupro Patch).
- Mimic dopamine effects in the brain, particularly useful in early-stage Parkinson's.
- Side effects encompass sleepiness, hallucinations, and compulsive behaviors.
MAO-B Inhibitors
- Selegiline (Eldepryl) and Rasagiline (Azilect) prevent dopamine breakdown through MAO-B inhibition.
- Used for increasing dopamine levels and improving motor function.
- Possible side effects: insomnia, nausea, headache, dizziness, rare increased blood pressure.
Combination ICS/LABA
- Fluticasone/Salmeterol (Seretide), Budesonide/Formoterol (Symbicort) combine corticosteroid and bronchodilator actions.
- Long-term asthma maintenance treatment aimed at controlling symptoms and preventing exacerbations.
- Side effects include oral thrush and increased heart rate.
Leukotriene Receptor Antagonists (LTRA)
- Montelukast (Singulair), Zafirlukast (Accolate) reduce airway inflammation by blocking leukotriene receptors.
- Effective in preventing asthma symptoms and exercise-induced bronchospasm.
- Side effects might include headache, abdominal pain, dizziness, and rare mood changes.
Theophylline (Methylxanthines)
- Theophylline (Uniphyllin, Slo-Phyllin) promotes bronchodilation and reduces airway responsiveness.
- Employed for asthma management, especially severe cases, while requiring monitoring due to narrow therapeutic range.
- Side effects include nausea, tremors, insomnia, and potential arrhythmias.
Long-Acting Muscarinic Antagonists (LAMA)
- Tiotropium (Spiriva Respimat) blocks muscarinic receptors to induce bronchodilation.
- Added in severe asthma therapy to improve lung function.
- Side effects include dry mouth, throat irritation, urinary retention, and constipation.
Oral Corticosteroids
- Prednisolone (Deltacortril) and Hydrocortisone (Solu-Cortef) manage systemic inflammation by suppressing the immune response.

Biologics (Monoclonal Antibodies)
- Omalizumab (Xolair), Mepolizumab (Nucala), Benralizumab (Fasenra) target specific immune pathways to mitigate airway inflammation.
- Reserved for severe asthma, especially allergic and eosinophilic types.

Short-Acting Anticholinergics
- Ipratropium Bromide (Atrovent) function to promote bronchodilation and decrease mucus.
