Pharmacological Interventions
Medication Selection Principles
1. Evidence-Based Prescribing
- Use medications with proven efficacy for indication
- Follow clinical practice guidelines
- Consider comparative effectiveness data
- Prefer medications with better safety profiles when equivalent efficacy
2. Patient-Specific Factors
- Comorbidities and contraindications
- Organ function (renal, hepatic)
- Drug allergies and intolerances
- Concurrent medications (drug interactions)
- Age, pregnancy status
- Genetic factors (pharmacogenomics when available)
- Cost and insurance coverage
3. Medication Safety
- Start low, go slow (especially in elderly, multiple comorbidities)
- Titrate to target dose based on response and tolerance
- Monitor for adverse effects
- Avoid potentially inappropriate medications (Beers Criteria for elderly)
- Polypharmacy reduction when possible
Common Medication Classes by Indication
Hypertension
First-Line Agents (per JNC-8, ACC/AHA guidelines):
- ACE Inhibitors (lisinopril, enalapril): Preferred if diabetes, CKD, or heart failure
- ARBs (losartan, valsartan): Alternative to ACE if intolerant
- Calcium Channel Blockers (amlodipine): Particularly effective in elderly, Black patients
- Thiazide Diuretics (chlorthalidone, HCTZ): Cost-effective, good CV outcomes
Dosing Strategy:
- Start single agent at low dose
- Titrate to maximum tolerated dose before adding second agent
- Combination therapy often needed (2-3 agents)
- Monitor BP response, adjust every 2-4 weeks
Type 2 Diabetes Mellitus
First-Line (ADA Standards of Care):
- Metformin: First-line for all patients unless contraindicated (eGFR <30)
- Start 500-850mg daily or BID, titrate to 2000mg total daily
Second-Line (individualize based on comorbidities):
- SGLT2 Inhibitors (empagliflozin, dapagliflozin): If heart failure or CKD (strong cardio-renal benefits)
- GLP-1 Receptor Agonists (semaglutide, dulaglutide): If ASCVD or high risk, weight loss needed
- DPP-4 Inhibitors (sitagliptin): If low hypoglycemia risk desired
- Sulfonylureas (glipizide): Cost-effective but hypoglycemia risk
- Insulin: If HbA1c very elevated ($>$10%) or symptoms of hyperglycemia
Depression
First-Line SSRIs (APA guidelines):
- Sertraline, escitalopram, fluoxetine, citalopram, paroxetine
- Start low (e.g., sertraline 50mg, escitalopram 10mg)
- Titrate after 2-4 weeks if partial response
- Full trial: 6-8 weeks at therapeutic dose
- Continue 6-12 months after remission (longer if recurrent)
Second-Line:
- SNRIs (venlafaxine, duloxetine): Especially if chronic pain comorbidity
- Bupropion: If sexual dysfunction concern, smoking cessation
- Mirtazapine: If insomnia/appetite stimulation needed
Augmentation (if partial response):
- Second antidepressant from different class
- Atypical antipsychotic (aripiprazole, quetiapine) - FDA-approved augmentation
- Lithium, thyroid hormone (triiodothyronine)
Chronic Pain
Multimodal Analgesia (WHO Pain Ladder, CDC Opioid Guidelines):
Non-Opioid Analgesics:
- Acetaminophen: 3-4g/day divided, safe if liver function normal
- NSAIDs: Ibuprofen, naproxen, meloxicam - short-term or chronic with GI protection
- Monitor: Renal function, BP, GI bleeding risk
Adjuvant Analgesics for Neuropathic Pain:
- Gabapentin: 300mg titrated to 1800-3600mg/day divided TID
- Pregabalin: 75mg BID titrated to 150-300mg BID (better bioavailability than gabapentin)
- SNRIs (duloxetine): 60mg daily for diabetic neuropathy, chronic MSK pain
- TCAs (amitriptyline, nortriptyline): Low-dose (10-75mg QHS) - second-line due to side effects
Topical Agents:
- Lidocaine patches 5%, diclofenac gel, capsaicin cream
- Local effect, minimal systemic absorption
Opioids (CDC guidelines - use cautiously):
- Only after non-opioid multimodal therapies inadequate
- Lowest effective dose, short-acting preferred initially
- Avoid $>$90 MME/day if possible
- UDS, PDMP monitoring, naloxone co-prescription
- Reassess frequently, taper if not meeting functional goals
Heart Failure with Reduced Ejection Fraction (HFrEF)
Guideline-Directed Medical Therapy (GDMT) - "Foundational Four":
ACE Inhibitor or ARB or ARNI
- ACE: Lisinopril 20-40mg daily, enalapril 10-20mg BID
- ARNI (Sacubitril/Valsartan): 24/26mg BID → 97/103mg BID (superior to ACE/ARB)
- Monitor: BP, renal function, potassium
Beta-Blocker
- Carvedilol 3.125-6.25mg BID → 25mg BID (target)
- Metoprolol succinate 12.5-25mg daily → 200mg daily
- Bisoprolol 1.25mg → 10mg daily
- Titrate slowly, monitor HR, BP
Mineralocorticoid Receptor Antagonist (MRA)
- Spironolactone 12.5-25mg daily (up to 50mg)
- Eplerenone 25mg daily → 50mg daily
- Monitor: Potassium, renal function (risk hyperkalemia)
SGLT2 Inhibitor
- Dapagliflozin 10mg daily or empagliflozin 10mg daily
- Reduces HF hospitalizations and mortality
- Also beneficial for diabetes and CKD
Additional Therapies:
- Loop diuretic (furosemide) for volume management (not mortality benefit)
- Hydralazine-isosorbide dinitrate (if African American or intolerant to ACE/ARB)
- Ivabradine (if EF $\leq$35%, HR $>$70 on max beta-blocker)
- Digoxin (symptomatic benefit, reduce hospitalizations)
Medication Documentation Best Practices
Include in Treatment Plan:
- Generic name (brand name optional)
- Dose, route, frequency
- Indication/rationale
- Titration plan if applicable
- Expected timeline for benefit
- Key side effects to monitor
- Drug interactions
- When to adjust or discontinue
Example: "Lisinopril 10mg PO daily - ACE inhibitor for hypertension and renal protection in diabetes. Titrate to 20mg in 2-4 weeks if BP not at goal and tolerating (monitor for cough, hyperkalemia). Target BP <130/80."
Non-Pharmacological Interventions
Lifestyle Modifications
Diet and Nutrition
Mediterranean Diet (Evidence: multiple RCTs, PREDIMED trial):
- Indications: Cardiovascular disease prevention, diabetes management
- Components:
- High intake: Fruits, vegetables, whole grains, legumes, nuts, olive oil
- Moderate: Fish, poultry
- Low: Red meat, sweets
- Evidence: Reduces cardiovascular events by 30%, improves glucose control

- Evidence: Reduces SBP by 8-14 mmHg
- Implementation: DASH eating plan education, sodium tracking
Carbohydrate Counting (for Diabetes):
- Consistent carbohydrate intake: 45-60g per meal
- Enables insulin dosing adjustment
- Prevents glycemic variability
- Dietitian teaches carb counting skills
Weight Management:
- Caloric deficit: 500-750 kcal/day for 1-2 lb/week weight loss
- Behavior change strategies: Self-monitoring, stimulus control, goal-setting
- Structured programs (Weight Watchers, MOVE!, etc.) more effective than self-directed
- Pharmacotherapy (GLP-1 agonists, orlistat) or bariatric surgery for BMI $\geq$30-35 with comorbidities
Physical Activity and Exercise
Aerobic Exercise:
- Recommendation: 150 min/week moderate intensity OR 75 min/week vigorous
- Moderate: Brisk walking, cycling, swimming - can talk but not sing
- Vigorous: Running, fast cycling - can say few words before pause
- Benefits: Cardiovascular health, glucose control, weight management, mood
- Implementation: Start with 10 min sessions, gradually increase
Resistance Training:
- Recommendation: 2-3 sessions/week, all major muscle groups
- Benefits: Muscle strength, bone density, metabolic rate, glucose control
- Implementation: Bodyweight exercises, resistance bands, free weights, machines
Balance and Flexibility:
- Important for fall prevention in elderly
- Yoga, tai chi
- Stretching routines
Exercise Prescription:
- FITT principle: Frequency, Intensity, Time, Type
- Individualize based on fitness level, comorbidities, goals
- Cardiac clearance if indicated (using ACSM or ACC/AHA guidelines)
Example: "Aerobic exercise: Walk 30 minutes, 5 days/week at moderate intensity (target HR 50-70% max). Resistance training: Upper and lower body exercises 2x/week, 2 sets of 10-12 reps."
Smoking Cessation
Evidence: Strongest intervention for COPD, cardiovascular disease, cancer prevention
5 A's Approach:
- Ask: Screen all patients for tobacco use
- Advise: Urge all tobacco users to quit
- Assess: Willingness to make quit attempt
- Assist: Aid in quitting (counseling + medication)
- Arrange: Follow-up contact
Pharmacotherapy (doubles quit rates):
- Nicotine Replacement: Patch, gum, lozenge - OTC, safe
- Varenicline: Most effective (Chantix), start 1 week before quit date
- Bupropion: Alternative, also treats depression
- Combination: NRT + varenicline/bupropion more effective
Counseling:
- Quitline: 1-800-QUIT-NOW
- Individual or group counseling
- Cognitive-behavioral techniques
Implementation: Set quit date within 30 days, prescribe pharmacotherapy + counseling referral, follow up within 1 week of quit date.

Implementation: 12-16 weekly 50-min sessions with trained therapist, homework between sessions
Variants:
- CBT-I (insomnia): Sleep restriction, stimulus control, cognitive therapy for sleep
- CBT-CP (chronic pain): Pain education, activity pacing, cognitive restructuring of pain catastrophizing
Motivational Interviewing (MI)
Indication: Ambivalence about behavior change (diet, exercise, substance use, medication adherence)
Principles:
- Express empathy
- Develop discrepancy (between current behavior and goals/values)
- Roll with resistance (don't argue)
- Support self-efficacy
Techniques:
- Open-ended questions
