pain medications?

DRUG

SAFETY ISSUES

NSAIDS (Aspirin)

NSAIDS
( Ibuprofen)

NSAIDS
(Mefenamic)

• May cause stomach irritation and bleeding
• Those under 18 should not take aspirin because of the risk of developing Reye Syndrome

• Can irritate the stomach lining and increase the risk for stomach bleeding and ulcers.
• Some medications, smoking, and drinking alcohol can increase this risk.

• Increased risk of serious and sometimes fatal heart and blood vessel problems (eg, heart attack, stroke). Risk may be greater if you already have heart problems or if you take it for a long time
• May cause an increased risk of serious and sometimes fatal stomach ulcers and bleeding

Ibuprofen safety data

• Meta-analysis of 12 case-control and cohort studies of the risk of admission for peptic ulcer complications associated with NSAIDs (Henry et al, 1996).

– Ibuprofen was associated with the least risk of serious upper gastrointestinal complications;

• Based on the comprehensive review and analyses of available data, although ibuprofen is the safest of the NSAIDs there appears to be a dose-related risk for GI and renal adverse events. However, at OTC doses of 1200 mg/day or less, the risks appear negligible

International Ibuprofen Foundation 2002

PROPYPHENAZONE
SAFETY ISSUES

How safe are the available OTC
pain medications with Propyphenazone?

DRUG

SAFETY ISSUES

Propyphenazone
combination
(with paracetamol
and caffeine)

• Pyrazolone derivatives which include aminophenazone, metanizole sodium, phenylbutazone and propyphenazone have been associated with serious
adverse effects. Since safer alternatives are available, some regulatory authorities have withdrawn or restricted their use.

•Increasing case reports on anaphylaxis; this leads to concern because it is available as OTC medication

Drug-associated Anaphylaxis

Drugs frequently associated with anaphylaxis wereglafenine, combination preparations with PROPYPHENAZONE, diclofenac, dextran, ibuprofen,floctafenine, allergen extracts, sulfamethoxazole with trimethoprim.

Drug associated anaphylaxis: 20 years of reporting in the Netherlands (1974-1994) and review of literature Clinical and Experimental Allergy

Reports of Anaphylaxis on Propyphenazone

Odds ratio for anaphylactoid reactions on the combination

Anaphylactic shock and anaphylactoid reaction

Propyphenazone 18.2 (10.6 -31.3)

Paracetamol 1.4 (1.2-1.6)

Caffeine 0.8 (0.1-5.7)

SAFETY ISSUES ON PROPYPHENAZONE:

• Regulatory actions :

– 9 countries took some sort of regulatory action
– 4 countries banned the product
– 5 countries have made some restrictions

• May affect the liver if dose used is inappropriate


Is paracetamol safe?

• On Paracetamol and liver injury:

– There are only slight increases in liver transaminases (0.4%-1%) after intake of therapeutic doses of Paracetamol
– Acute supratherapeutic paracetamol ingestion and hospitalization for acute toxicity and poisoning remain low
– Paracetamol-induced acute liver failure is mostly due to overdose ( unintentional - 48%; intentional - 44%) and not due to therapeutic doses

Pharmacotherapy. 2007 Sep; 27(9): 1219-30

Recognizing the
Paracetamol ADVANTAGE:

First used clinically by Von
Mering in 1893.

Called the non-aspirin pain
reliever

Marketed in US – 1950; in
UK- 1956

Paracetamol has no significant action on COX1, thus its freedom from Gastrointestinal side effects

Over the counter status (OTC) in the US since 1955

Recognizing the
Paracetamol ADVANTAGE:

INDICATION

COMMENT

HEADACHE

Three randomized, multicenter, double-blind, single-dose, placebo-controlled studies have been conducted by McNeil , which evaluated the efficacy of acetaminophen in the tension headache model.

Post-Oral Surgery Pain, Episiotomy pain, Orthopedic Surgery Post-Immunization Muscle Aches and Pain Sore Throat

Adverse effects like hepatotoxicity may only be seen in:

the 21st century. BUT, more than a little old
fashioned CAUTION is called for in the
consumption and recommendation of these
drugs”
