Study Notes
NSAIDs and Rheumatologic Diseases
- Estimated prescription rate of NSAIDs for patients with rheumatologic diseases is notably high.
- Most NSAIDs have a bioavailability of about 50% when taken at therapeutic doses.
- Protein binding affinity for most NSAIDs is typically high, often exceeding 90%.
- Volume of distribution for most NSAIDs is significant, indicating widespread distribution in body tissues.
- NSAIDs that achieve synovial fluid concentrations approximately half of plasma concentration include ibuprofen and naproxen.
- Common adverse effect associated with NSAID use is gastrointestinal bleeding.
- Plasma elimination half-life range for piroxicam is around 30 to 70 hours.
- Ketoprofen undergoes extensive first-pass metabolism with oral bioavailability near 50%.
- Plasma protein binding saturation impacts naproxen concentration, leading to increased free drug levels.
- Naproxen shows a trend toward minimal cardiovascular risk.
NSAID Overdose and Usage
- Initial clinical manifestations of NSAID overdose may include nausea, vomiting, and gastrointestinal distress.
- Diclofenac has topical activity and is utilized in ophthalmologic solutions.
- Renal excretion percentage for indomethacin is about 60%, while for ketorolac it is around 90%.
- Flurbiprofen holds the distinction of the shortest plasma elimination half-life at therapeutic dosing.
Antidepressant Drugs
- Tricyclic Antidepressants (TCA) are primarily used to treat depression resistant to other classes due to significant toxicity.
- Key neurotransmitters involved in depression include serotonin, norepinephrine, and dopamine.
- Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs) are linked with neuralgic pain, migraines, enuresis, and ADHD treatments.
- Selective Serotonin Reuptake Inhibitors (SSRIs) treat obsessive-compulsive disorders, panic disorder, alcoholism, obesity, migraine headaches, and chronic pain syndromes.
- Atypical Antidepressants exhibit fewer side effects compared to other classes.
- Increased norepinephrine activity alongside serotonin is associated with Atypical Antidepressants.
- Neurotransmitter activity involved in depression is primarily centered around the monoamine system.
- Certain antidepressants can have a physiological effect on enuresis, particularly the TCAs.
- Dopamine is a neurotransmitter additionally linked to depression.
Antidepressants and Toxicity
- TCA class features antimuscarinic activity, leading to various side effects.
- Monoamine oxidase (MAO) is responsible for the destruction of neurotransmitters within mitochondria.
- Primary cause of specific depression types linked to decreased norepinephrine is the dysregulation of neurotransmitter systems.
- Tricyclic antidepressants are distinguished by their three-ring chemical structure.
- Amitriptyline is associated with the highest reported toxicities in TCA poisoning studies.
- Toxicities of TCAs differ from those of antipsychotics primarily due to their pharmacodynamic profiles.
- Key factor in TCA toxicity versus antipsychotics is the broader range of systems affected, including cardiovascular and central nervous systems.
- Variations in adult toxic doses of TCAs arise from individual pharmacokinetics, including metabolic differences.
Depression Symptoms and Mechanisms
- Predominant symptoms of depression include persistent sadness and loss of interest.
- Feelings of sadness, anxiety, or emptiness are often attributed to neurochemical imbalances.
- The main role of MAO is to regulate neurotransmitter levels by degrading excess neurotransmitters.
