Combination products containing codeine (a mild opioid analgesic and cough suppressant) with non-opioid analgesics are used for the relief of mild to moderate pain unresponsive to non-opioid analgesics alone. These combinations are often found in over-the-counter or prescription formulations for short-term management of pain. Codeine use is approved in certain countries, but its use is restricted or banned in pediatric populations and in some locations due to abuse potential and safety concerns.
Pharmacokinetics
Estimated pharmacokinetic parameters for an adult population based on literature for codeine-containing fixed-dose combination tablets administered orally. Model reflects typical values for codeine with non-opioids in healthy adults. No direct publication reporting full model PK for N02AJ09 combination product.
