NSG 533 Advanced Pharmacology Bone
and Joint Disorders
What is the everyday presentation of Osteoarthritis and the general desires of remedy?
Patients are usually greater than 50 years old. May be asymptomatic to excessive joint ache
and stiffness. Joint involvement is uneven. Inflammation is absent or mild. Cardinal s/s are
use-associated joint pain (deep and aching), joint stiffness (abates with movement, recurs with
relaxation), weight bearing joints risky, joint stiffness lasts fewer than 30 minutes. One or greater
joints can be involved however most commonplace are distal finger joints, proximal finger joints,
first carpometacarpal joint, knees, hips, cervicolumbar backbone, and joint of the high-quality
toe. Examination of the joint may additionally display tenderness, crepitus, muscle atrophy, and
constrained ROM.
Osteoarthritis (OA) treatment dreams
Educate the affected person and caregivers o Relieve ache o Maintain or restore mobility o
Minimize useful impairment and associated damaging outcomes (like falls) o Preserve joint
integrity o Improve exceptional of lifestyles
Osteoarthritis (OA)
innovative, degenerative joint sickness with lack of articular cartilage and hypertrophy of bone
(formation of osteophytes, or bone spurs) at articular surfaces
Provide a stepwise technique to the treatment of osteoarthritis, together with
non-pharmacological interventions (discern fifty eight-2).
1) non pharm, 2) pharm (Tylenol APAP/nsaids + glucosamine), then 3) injections, opioids,
surgical treatment *If NSAIDS are contraindicated, then utilize glucocorticoid injections
What is supposed by means of good enough dose / length and ATC dosing when determining
APAPs effectiveness
APAP: first line remedy for mild to mild osteoarthritis Apap ought to be attempted to start with at
an good enough dose and period earlier than thinking about an NSAID* Insufficient
acetaminophen dose or period are commonplace reasons for inadequte response. APAP have
to accept on a PRN basis in divided doses as much as 4 g each day. Single doses should now
not exceed 1 g. Trial for four to six weeks. Use 2.5g max for pts who consume 2 to three
, alcoholic beverages/each day. Consider opportunity medicinal drugs if pain not
managed/presence of intense pain and/or infection.
When need to NSAIDs be introduced
NSAIDS are a primary line therapy for patients with moderate to extreme OA or alternative
remedy APAP when APAP fails to offer an acceptable analgesic response or if there's an
inflammatory aspect. All systemic NSAIDS are related to negative GI, renal, hepatic,
cardiovascular, CNS, hypertensive effects.. Especially in older individuals. Inhibition of the cox-1
enzyme is concept to be responsible by and large for the adverse results at the gastric mucosa,
kidney, and platelets. Cox-2 inhibitors (Celebrex) are favored for patients at excessive hazard
for GI complications
Practice question: Understand while you will use Acetaminophen as opposed to an NSAID or an
NSAID in preference to Acetaminophen
NSAIDs work first-rate on inflammatory pain or pain mediated by way of prostaglandins (RA,
menstrual and submit-surgical pain) and bony metastasis. NSAIDs include increased GIB risk
and renal impairment. APAP is a superb first line for mild to moderate pain and taken into
consideration the first line in low returned ache and osteoarthritis. APAP hepatotoxicity has
happened in people with liver damage or chronic drinkers. (pg 576)*
Who could benefit from COXib?
Coxib or cox 2 inhibitors are desired for patients at chance for GI headaches, especially while
using with a PPI.
OTC merchandise for osteoarthritis
APAP (topical and oral), ibuprofen, naproxen, aspirin), diclofenac gel
- Glucosamine and Chondroitin
that are used to stimulate the cartilage matrix and protect towards oxidative chemical harm.
Improves knee symptoms in OA just like celecoxib. D/C after 3 to six months if no benefit
achieved. Do now not use glucosamine if allergic reaction to shellfish.
Capsaicin
also can be used to dissipate substance P from spinal sensory neurons and lowering pain
transmission. Not effective for acute pain... Because it can take up to 2 weeks of day by day
administration to work. Instruct pt to avoid eyes/mucous membranes and wash palms after
utility!
