Bioactive Compound:1,3,7-Trimethylxanthine (Caffeine)

Biological Target:Cytochrome P450 1A2 (CYP1A2) & Adenosine A1/A2A Receptors

Clinical Mechanism:

Ciprofloxacin, fluvoxamine, and oral contraceptives inhibit CYP1A2, reducing caffeine clearance by 30-80% and precipitating palpitations, panic, and severe tremors. Caffeine also accelerates gastric motility, impairing bisphosphonate and thyroid absorption.

Patient Actionable Rule:Take thyroid hormones and bisphosphonates with pure plain water only. Moderate or avoid concentrated caffeine during ciprofloxacin therapy.

HIGH

Alcoholic Beverages (Beer, Wine, Spirits)

Bioactive Compound:Ethanol

Biological Target:GABA-A Receptors, Hepatic CYP2E1 & Gluconeogenesis

Clinical Mechanism:

Multiplies respiratory depression and profound sedation with opioids and sedatives; blocks hepatic lactate uptake with metformin (lactic acidosis); triggers acute disulfiram-like vomiting and tachycardia with metronidazole; and accelerates dose-dumping in extended-release capsules.

Patient Actionable Rule:Completely abstain from alcohol while taking metronidazole, cephalosporins, prescription sedatives, or empty-stomach metformin.
