III. Detailed Overview of Drug Classes (Examples - Not Exhaustive List)

Due to the extensive nature of this topic, a full detailed listing of 200 drugs is beyond the scope of this article. Instead, we will provide examples within key therapeutic classes to illustrate the level of detail a pharmacy technician should aim for in their studies.

A. Cardiovascular Drugs:

• Antihypertensives: This class includes many agents working through different mechanisms. Examples include:

  • ACE Inhibitors (e.g., Lisinopril, Ramipril): Inhibit the angiotensin-converting enzyme, lowering blood pressure. Side effects may include cough, hyperkalemia, and angioedema.
  • Angiotensin Receptor Blockers (ARBs) (e.g., Valsartan, Losartan): Block angiotensin II receptors, lowering blood pressure. Side effects are similar to ACE inhibitors, but cough is less common.
  • Beta-Blockers (e.g., Metoprolol, Atenolol): Reduce heart rate and blood pressure. Side effects can include bradycardia, fatigue, and bronchospasm.
  • Calcium Channel Blockers (e.g., Amlodipine, Diltiazem): Relax blood vessels, lowering blood pressure. Side effects may include headache, dizziness, and peripheral edema.
  • Diuretics (e.g., Hydrochlorothiazide, Furosemide): Increase urine output, reducing blood volume and pressure. Side effects can include dehydration, electrolyte imbalances, and dizziness.

• Antianginals (e.g., Nitroglycerin): Dilate coronary arteries, increasing blood flow to the heart. Side effects can include headache, dizziness, and hypotension.

• Antiarrhythmics (e.g., Amiodarone, Lidocaine): Restore normal heart rhythm. Side effects vary greatly depending on the specific drug.

• Lipid-Lowering Agents (e.g., Atorvastatin, Simvastatin): Lower cholesterol levels. Side effects can include muscle aches (myalgia) and elevated liver enzymes.

B. Central Nervous System (CNS) Drugs:

• Antidepressants: Many classes exist, including:

  • Selective Serotonin Reuptake Inhibitors (SSRIs) (e.g., Sertraline, Fluoxetine): Increase serotonin levels in the brain. Side effects may include nausea, sexual dysfunction, and insomnia.
  • Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs) (e.g., Venlafaxine, Duloxetine): Increase both serotonin and norepinephrine levels. Side effects are similar to SSRIs.
  • Tricyclic Antidepressants (TCAs) (e.g., Amitriptyline, Nortriptyline): Older class with more side effects.

• Antipsychotics (e.g., Risperidone, Olanzapine): Treat psychosis and schizophrenia. Side effects can include weight gain, sedation, and extrapyramidal symptoms.

• Anxiolytics (e.g., Diazepam, Lorazepam): Reduce anxiety and promote relaxation. Side effects can include sedation, dizziness, and dependence.

• Analgesics (e.g., Acetaminophen, Ibuprofen): Relieve pain and reduce fever. Side effects vary depending on the drug and dosage. Acetaminophen overdose is extremely dangerous.

C. Respiratory Drugs:

• Bronchodilators (e.g., Albuterol, Salmeterol): Relax airway muscles, improving breathing. Side effects can include tremor and tachycardia.

• Corticosteroids (e.g., Fluticasone, Budesonide): Reduce inflammation in the airways. Side effects can include oral thrush and hoarseness.

• Expectorants (e.g., Guaifenesin): Loosen mucus in the airways.

D. Gastrointestinal Drugs:

• Antacids (e.g., Calcium Carbonate, Magnesium Hydroxide): Neutralize stomach acid.

• Proton Pump Inhibitors (PPIs) (e.g., Omeprazole, Pantoprazole): Reduce stomach acid production. Long-term use can increase the risk of bone fractures and infections.

• Antidiarrheals (e.g., Loperamide): Slow bowel movements.

E. Endocrine Drugs:

• Insulin (various types): Controls blood sugar levels in diabetes.

• Thyroid Hormones (e.g., Levothyroxine): Replace missing thyroid hormone.

• Oral Contraceptives (various types): Prevent pregnancy.

F. Anti-infective Agents:

• Antibiotics (various classes): Kill or inhibit the growth of bacteria. Important to note the specific spectrum of activity for each antibiotic.

• Antifungals (various classes): Treat fungal infections.
