presents with BP 156/94 mmHg, HR 82 bpm, K+ 4.2 mEq/L, and uric acid 7.8 mg/dL. Which antihypertensive is
most appropriate, and which two agents are contraindicated?
• Verified Clinical Rationale: Initiate an ARB (Losartan) or Dihydropyridine CCB (Amlodipine). Losartan blocks AT1
receptors while uniquely inhibiting proximal tubular URAT1 transporters (uricosuric effect), lowering serum uric
acid and preventing gout flares. Hydrochlorothiazide (HCTZ) is contraindicated because thiazides inhibit uric acid
excretion and precipitate acute gouty arthritis. Propranolol (non-selective β1/β2 blocker) is strictly contraindicated
because β2 antagonism triggers lethal bronchospasm in asthma.

, MODULE 1: PRESCRIPTIVE AUTHORITY, DEA SCHEDULES & CYP450 CLINICAL RULES
1. Federal DEA Controlled Substance Schedules (APRN / Clinician Prescribing Rules)
Schedule I (C-I): Highest abuse potential; no accepted medical use (Heroin, LSD, Psilocybin, Mescaline). Cannot be
prescribed.
Schedule II (C-II): High abuse potential; severe physical/psychological dependence (Oxycodone, Fentanyl, Morphine,
Hydromorphone, Methylphenidate, Amphetamine salts). Zero refills permitted. Requires a new written or certified
Electronic Prescribing for Controlled Substances (EPCS) order every time.
Schedule III (C-III): Moderate physical / high psychological dependence (Buprenorphine/Naloxone [Suboxone], Tylenol
#3 [Codeine + APAP], Ketamine, Testosterone). Maximum 5 refills within 6 months; phone/fax/electronic permitted.
Schedule IV (C-IV): Lower abuse potential (Benzodiazepines [Alprazolam, Lorazepam, Diazepam], Zolpidem, Tramadol,
Phenobarbital). Maximum 5 refills within 6 months.
Schedule V (C-V): Lowest controlled abuse potential (Pregabalin [Lyrica], Diphenoxylate/Atropine [Lomotil],
antitussives with <200 mg codeine/100 mL). Refilled as authorized per state dispensing rules.
2. High-Yield Cytochrome P450 (CYP450) Inducers vs. Inhibitors (Exam Trap Alert)
• CYP450 Inducers ("CRAP GPS" — Accelerate hepatic metabolism → ↓ Plasma drug levels → Therapeutic
Failure): Carbamazepine, Rifampin, Alcohol (chronic), Phenytoin, Griseofulvin, Phenobarbital, St. John’s Wort (+
Tobacco via CYP1A2). Clinical Trap: Adding Rifampin or St. John’s Wort to Warfarin (subtherapeutic
INR/thrombosis) or Oral Contraceptives (unintended pregnancy).
• CYP450 Inhibitors ("SICKFACES.COM" — Block hepatic metabolism → Spike drug levels → Severe Toxicity):
Sodium Valproate, Isoniazid, Cimetidine, Ketoconazole/Fluconazole, Fluoxetine, Alcohol (acute binge),
Ciprofloxacin, Erythromycin/Clarithromycin, Sulfonamides (TMP-SMX), Omeprazole, Metronidazole, plus
Amiodarone & Grapefruit Juice (intestinal CYP3A4). Clinical Trap: Co-prescribing Clarithromycin or Grapefruit
Juice with Simvastatin/Atorvastatin precipitates severe rhabdomyolysis.
