Migraine is a primary headache disorder characterized by recurrent attacks. Acetaminophen, nonsteroidal anti-inflammatory drugs, triptans, antiemetics, ergot alkaloids, and combination analgesics have evidence supporting their effectiveness in the treatment of migraine. Acetaminophen and nonsteroidal anti-inflammatory drugs are first-line treatments for mild to moderate migraines, whereas triptans are first-line treatments for moderate to severe migraines. ⋯ Other medications such as dihydroergotamine and antiemetics are recommended for use as second- or third-line therapy for select patients or for those with refractory migraine. The pharmacologic properties, potential adverse effects, cost, and routes of administration vary widely, allowing therapy to be individualized based on the pattern and severity of attacks. Several treatment principles, including taking medication early in an attack and using a stratified treatment approach, can help ensure that migraine treatment is cost-effective.

It has been debated whether mild analgesics, mainly paracetamol, adversely affect aspects of neurodevelopment. We examined whether mother's use of paracetamol, aspirin or ibuprofen in pregnancy is associated with increased risk of cerebral palsy (CP) in the child. ⋯ We observed an increased risk of spastic CP in children prenatally exposed to paracetamol and aspirin. Although we controlled for several important indications for analgesic use, we cannot exclude the possibility of confounding by underlying diseases.

Randomized Controlled Trial
Correlation of Pain Reduction with fMRI BOLD Response in Osteoarthritis Patients Treated with Paracetamol: Randomized, Double-Blind, Crossover Clinical Efficacy Study.
To assess the relationship between the analgesic efficacy of extended-release paracetamol (ER-APAP) and brain blood oxygen level-dependent (BOLD) signal activation in response to painful stimulation measured by functional magnetic resonance imaging (fMRI) in patients with osteoarthritis of the knee. ⋯ ER-APAP had a significantly greater effect than placebo and no treatment in reducing knee pain, which was associated with reduced BOLD signal activations in pain pathways, including the sensory cortex and supramarginal gyrus. BOLD observations after placebo treatment may shed light on the role of the brain regions potentially involved in placebo response in clinical trials investigating pain therapies.

To evaluate the efficacy between intravenous and oral acetaminophen as adjunct to multimodal analgesia regimens for pain management after total knee and hip arthroplasties. ⋯ Intravenous acetaminophen to multimodal analgesia dose not demonstrate a significant benefit in reducing pain and opioid consumption compared oral formulation after total knee arthroplasty and total hip arthroplasty. Higher-quality RCTs are required for further research.

Risk stratification after paracetamol overdose using mechanistic biomarkers: results from two prospective cohort studies.
Paracetamol overdose is common but patient stratification is suboptimal. We investigated the usefulness of new biomarkers that have either enhanced liver specificity (microRNA-122 [miR-122]) or provide mechanistic insights (keratin-18 [K18], high mobility group box-1 [HMGB1], and glutamate dehydrogenase [GLDH]). The use of these biomarkers could help stratify patients for their risk of liver injury at hospital presentation. ⋯ Edinburgh and Lothians Health Foundation, UK Medical Research Council.
