Study Notes
Drug Classification
- Drugs can be categorized based on several factors:
- Therapeutic use (e.g., antimicrobial, antidiabetic)
- Mode of action (e.g., receptor blocker, enzyme inhibitor)
- Site of action (e.g., loop diuretic, cell wall inhibitor)
- Molecular structure (e.g., glycoside, alkaloid, steroid)
Non-Proprietary Names (Generic Names)
- Using non-proprietary names (generic names) in prescriptions is beneficial for:
-
Clarity: Generic names reveal the drug class (e.g., benzodiazepines, beta-blockers).
- Examples:
- Drugs ending in "-azepam" (e.g., diazepam, nitrazepam) are benzodiazepines.
- Drugs ending in "-olol" (e.g., atenolol, metoprolol, bisoprolol) are beta-blockers.
- Drugs ending in "-pril" (e.g., lisinopril, enalapril) are ACE inhibitors.
- Drugs ending in "-floxacin" (e.g., ciprofloxacin, levofloxacin) are quinolone antibacterials.
- Examples:
- Economy: Generally, generic drugs are less expensive than their brand-name counterparts.
- Convenience: Pharmacists can provide the available generic version, instead of only the specific brand name.
-
Clarity: Generic names reveal the drug class (e.g., benzodiazepines, beta-blockers).
Proprietary Names
- Using proprietary (brand) names in prescriptions is sometimes necessary for:
- Consistency: Maintains consistent product quality and bioavailability. Crucial for drugs with a narrow therapeutic window.
- Critical Low Therapeutic Index Drugs: Essential for drugs like digoxin and warfarin, where small dosage variations affect patients significantly.
- Complex Formulations: Necessary for specialized drugs, like sustained-release versions.
- Mixtures and International Use: Proprietary names are beneficial when prescribing mixtures of drugs or for international travelers with chronic conditions. Different countries may use different brand names.
