PAIN

• Most common reason to seek medical care• Acute– Sudden and severe– Burn– Corneal abrasion, preseptal cellulitis

• Chronic– Lasts longer than 3 months– Back pain– Post-herpetic neuralgia– Sinusitis– Migraine

TYPES OF PAIN

• Somatic• Visceral• Neuropathic• Psychogenic

ANALGESIA

• Word of Greek origin• “an” meaning without• “algein” meaning to feel pain• Generally classified – Mild– Moderate– Strong

MILD ANALGESICS

• Acetylsalicylic acid– Aspirin or “ASA”

• Acetaminophen– Tylenol® or “APAP”

• Propoxyphene (Schedule IV)-removed from market– Darvon®

– Darvocet®

SALICYLATES- THE FOUR “As”

• Analgesic– Relief without sedation– Works on peripheral pain receptors– Decreases synthesis of prostaglandins and

bradykinins• Anti-inflammatory– Blocks kinin precursors– Blocks histamine precursors– Need high doses for arthritic pain• Approx 4-6 grams daily

SALICYLATES- THE FOUR “A”

• Anti-platelet– Not related to pain treatment– For heart attack and stroke prevention– Inhibits platelet adhesiveness and coagulation– Regular strength is 325mg; baby aspirin is 81mg

• Antipyretic-“pyrexis” Greek for heat– Affects the hypothalamus which is responsible for

temperature regulation– Decreases temperature but not below normal– Inhibits pyrogen stimulated prostaglandins

ASPIRIN SIDE EFFECTS

• Max daily dose = 4000mg (4g)• Reye’s Syndrome in children with flu-like

symptoms• GI irritation• Bleeding ulcers• Increased anticoagulation• Nausea • Tinnitus– Often seen at arthritic doses

ALLERGIC TO ASPIRIN?

• Triad leading to anaphylaxis – Aspirin allergy– Asthma– Nasal polyps

• Avoid the following:– Aspirin– Oral NSAIDS– Topical NSAIDS

ACETAMINOPHEN

• Clear mechanism of action elusive– May affect oxidation of cyclooxygenase (COX) and

inhibit prostaglandin synthesis in the CNS– May increase endogenous cannabinoids

• Analgesic action• Anti-pyretic action• No anti-inflammatory action• No anti-platelet action

ACETAMINOPHEN DOSING

• aka APAP• OTC 325mg regular strength• 500mg extra strength• 4000mg/day (4 gram) max dosage• Used extensively in flu/cold/pain preps• Watch ingredient lists to avoid overdosage

ACETAMINOPHEN SIDE EFFECTS

• Generally well tolerated at therapeutic dosages

• Overdosage causes irreversible kidney and liver damage

• Cannot use in patients with hepatic disease or alcoholics

• Do not use with alcohol• Check ingredients on cough/cold preps

MODERATE ANALGESICS

• Codeine (Tylenol #3®, Tylenol #4®)• Hydrocodone (Vicodin®, Vicoprofen®,

Lorcet®, Lortab®)• Oxycodone (Percocet®, Percodan®)• NSAIDS (ibuprofen, Naproxen®, others)• Tramadol (Ultram®, Ultracet®)

CODEINE

• Naturally occurring substance• From the opium poppy• 1/12 the strength of morphine• Rarely used alone• Tylenol #3® (APAP and codeine)• Empirin #3® (ASA and codeine)• Also used as an antitussive in cough syrups

CODEINE COMBINATIONS

• Tylenol #3® and Tylenol® #4• Increasing codeine amount from #3 to #4• APAP amount is 325mg in each• #3-30mg codeine + 325mg APAP• #4-60mg codeine + 325mg APAP• Tylenol with codeine® elixir is APAP

120mg/5cc with 12mg codeine/5cc

TYLENOL #3

• Schedule III• Central acting narcotic analgesic• 325mg acetaminophen + 30mg codeine• Avoid in liver/renal disease/alcoholism• No extra Tylenol® in addition• No alcohol• GI distress and sedation are main side

effects

ALLERGIC TO CODEINE?• Most codeine “allergies” are just GI side

effects or codeine initiated histamine release– “Stomach upset”– Flushing– Itching

• True IgE mediated allergic reaction low • Can use hydrocodone because it is a semi-

synthetic form of codeine

HYDROCODONE

• As effective as Class II narcotics but with Class III status

• Significantly more pain relief and duration of action compared to codeine

• Induces euphoria• Highly addictive• Also has antitussive properties

HYDROCODONE PRODUCTS

• Vicodin® (APAP w/hydrocodone)– 500mg APAP + 5mg hydrocodone– Schedule III

• Vicodin® ES (APAP w/hydrocodone) – 750mg APAP + 7.5mg hydrocodone– Schedule III

• Vicoprofen®

– 200mg ibuprofen + 7.5mg hydrocodone– When Tylenol® is contraindicated/liver disease– Schedule III
