How L612 white pill and l484 pill Work in the Body (Mechanism of Action)

L612 white pill:

Loratadine works by blocking histamine H1 receptors in your body. Histamines are chemicals released during allergic reactions that cause sneezing, itching, and watery eyes. By blocking these, L612 prevents symptoms before they start.

• ✔️ Works in peripheral receptors only (why it’s non-drowsy)

• ✔️ Starts working within 1–3 hours

• ✔️ Peak effectiveness at 8–12 hours

l484 white pill:

Acetaminophen reduces pain by blocking COX enzymes in the brain (not the rest of the body like NSAIDs). This stops the production of prostaglandins — the chemicals that send pain and fever signals.

• ⚠️ Doesn’t reduce inflammation (unlike ibuprofen)

• ⏱️ Works in ~30 minutes

• Metabolized in the liver (overdose risk if abused)
