Pharmacokinetic Properties of Ibuprofen (IBU) From the Fixed-Dose Combination IBU/Caffeine (400/100 mg; FDC) in Comparison With 400 mg IBU as Acid or Lysinate Under Fasted and Fed Conditions-Data From 2 Single-Center, Single-Dose, Randomized Crossover Studies in Healthy Volunteers.

Rapid onset of analgesic action is linked with rapid absorption of analgesics (high maximum concentration [C ] and short time to maximum concentration [t ]). After overnight fasting, ibuprofen lysinate reaches higher peak plasma levels (C ) earlier than ibuprofen acid (t ) with comparable exposure (area under the plasma concentration-time curve [AUC]); however, subjects usually take ibuprofen with or within a short time of a meal. Therefore, pharmacokinetic (PK) studies under fed conditions may better chara...

The acyl-glucuronide metabolite of ibuprofen has analgesic and anti-inflammatory effects via the TRPA1 channel.

Ibuprofen is a widely used non-steroidal anti-inflammatory drug (NSAID) that exerts analgesic and anti-inflammatory actions. The transient receptor potential ankyrin 1 (TRPA1) channel, expressed primarily in nociceptors, mediates the action of proalgesic and inflammatory agents. Ibuprofen metabolism yields the reactive compound, ibuprofen-acyl glucuronide, which, like other TRPA1 ligands, covalently interacts with macromolecules. To explore whether ibuprofen-acyl glucuronide contributes to the ibuprofen ana...
