INVAGESIC vs WYGESIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
INVAGESIC is a combination of pregabalin, an alpha2-delta ligand that inhibits presynaptic calcium channels to reduce excitatory neurotransmitter release, and meloxicam, a COX-2 selective NSAID that decreases prostaglandin synthesis via cyclooxygenase inhibition.
WYGESIC (ibuprofen and hydrocodone) combines a nonsteroidal anti-inflammatory drug (ibuprofen) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, and a narcotic analgesic (hydrocodone) that acts as a mu-opioid receptor agonist.
Adults: 1-2 tablets (325 mg acetaminophen/5 mg hydrocodone) orally every 4-6 hours as needed for pain, not to exceed 12 tablets per day.
1-2 tablets (paracetamol 325 mg / tramadol 37.5 mg) orally every 4-6 hours as needed for pain, not to exceed 8 tablets per day.

Terminal elimination half-life: 4-6 hours in adults; prolonged to 8-12 hours in elderly or mild renal impairment
3–4 hours in healthy adults; prolonged to 5–6 hours in moderate renal impairment (CrCl 30–50 mL/min) and >11 hours in severe renal impairment (CrCl <30 mL/min).
Renal: ~70% as unchanged drug; biliary/fecal: ~30% as metabolites
Primarily renal: 90% as unchanged drug and glucuronide conjugate; <5% fecal.
