Examples of Medications for Hypertension, Diabetes, and Asthma
The most effective medications for hypertension, diabetes, and asthma include ACE inhibitors, metformin, and inhaled corticosteroids respectively, based on their proven ability to reduce morbidity and mortality.
Hypertension Medications
Hypertension treatment should include drug classes that have demonstrated cardiovascular event reduction in patients with diabetes 1:
First-line options:
ACE inhibitors (e.g., lisinopril, enalapril, benazepril)
- Particularly beneficial for patients with diabetes or albuminuria
- Shown to reduce cardiovascular events and slow kidney disease progression
Angiotensin Receptor Blockers (ARBs) (e.g., losartan, valsartan, candesartan)
- Alternative for patients who cannot tolerate ACE inhibitors
- Recommended first-line for patients with albuminuria
Thiazide-like diuretics (e.g., chlorthalidone, indapamide)
- Long-acting agents preferred due to proven cardiovascular benefit
- Often used in combination therapy
Dihydropyridine Calcium Channel Blockers (e.g., amlodipine)
- Effective blood pressure reduction with few metabolic side effects
Second-line/Add-on options:
- Mineralocorticoid Receptor Antagonists (e.g., spironolactone)
- For resistant hypertension not controlled on three medications
- Requires monitoring for hyperkalemia
Treatment algorithm:
- For BP 130-150/80-90 mmHg: Start with single agent
- For BP ≥150/90 mmHg: Start with two-drug combination
- For resistant hypertension: Add mineralocorticoid receptor antagonist
Combinations to avoid:
- ACE inhibitor + ARB
- ACE inhibitor/ARB + direct renin inhibitor
Diabetes Medications
First-line:
- Metformin
- First-line therapy for type 2 diabetes
- Reduces hepatic glucose production and improves insulin sensitivity
- Caution with renal impairment and potential for lactic acidosis 2
Second-line options:
Sodium-glucose cotransporter-2 (SGLT2) inhibitors (e.g., empagliflozin, dapagliflozin)
- Cardiovascular and renal benefits
- Weight loss effect
Glucagon-like peptide-1 (GLP-1) receptor agonists (e.g., semaglutide, dulaglutide)
- Cardiovascular benefits
- Weight loss effect
Dipeptidyl peptidase-4 (DPP-4) inhibitors (e.g., sitagliptin, linagliptin)
- Weight neutral
- Well tolerated
Sulfonylureas (e.g., glipizide, glimepiride)
- Effective glucose lowering
- Risk of hypoglycemia
Thiazolidinediones (TZDs) (e.g., pioglitazone)
- Improve insulin sensitivity
- May have additional benefit of reducing asthma risk in overweight/obese patients 3
Insulin (various formulations)
- For type 1 diabetes and advanced type 2 diabetes
- Multiple formulations for basal and prandial coverage
Asthma Medications
Controller medications:
Inhaled corticosteroids (ICS) (e.g., fluticasone, budesonide)
- First-line controller therapy
- Reduce airway inflammation
Long-acting beta-agonists (LABAs) (e.g., salmeterol, formoterol)
- Used in combination with ICS
- Not to be used as monotherapy
Long-acting muscarinic antagonists (LAMAs) (e.g., tiotropium)
- Add-on therapy for uncontrolled asthma
Leukotriene modifiers (e.g., montelukast)
- Alternative controller option
- Less effective than ICS
Rescue medications:
Short-acting beta-agonists (SABAs) (e.g., albuterol, salbutamol)
- Rescue therapy for acute symptoms
- Overuse indicates poor control
Short-acting muscarinic antagonists (SAMAs) (e.g., ipratropium)
- Additional bronchodilator option
- Often used in emergency settings
Biologics for severe asthma:
- Anti-IgE (e.g., omalizumab)
- Anti-IL-5 (e.g., mepolizumab, reslizumab)
- Anti-IL-4/IL-13 (e.g., dupilumab)
Important Considerations
Comorbidity management:
- Hypertension is more prevalent in asthmatic patients and associated with increased asthma morbidity 4
- ACE inhibitors may have additional benefits in reducing asthma risk in overweight/obese patients with diabetes or hypertension 3
- Beta-blockers for hypertension should be used cautiously in asthma patients due to potential bronchospasm
Medication interactions:
- Thiazide diuretics may worsen glycemic control in diabetic patients 2
- Corticosteroids (oral) for severe asthma can worsen both hypertension and diabetes
- Some calcium channel blockers may affect glycemic control 2
Special populations:
- In pregnancy, ACE inhibitors and ARBs are contraindicated due to fetal risk 1
- In chronic kidney disease, ACE inhibitors or ARBs are preferred for hypertension management 5
- In elderly patients, start with lower doses and titrate carefully 5
By selecting appropriate medications based on comorbidities and individual patient factors, clinicians can effectively manage these common chronic conditions while minimizing adverse effects and drug interactions.
