Study Notes
Drug Absorption
- Drug absorption effects vary by drug type, entry rate into the bloodstream, concentration, and other influencing factors.
- How a drug enters the body affects its absorption rate and overall effect.
- Alcohol does not require digestion, leading to faster absorption compared to food.
Alcohol Absorption
- Blood alcohol level (BAL) is measured by concentration rather than total content in the system.
- Approximately 70%-80% of alcohol is absorbed in the small intestine.
- Faster absorption of alcohol occurs since it does not need digestion, unlike food.
Factors Influencing Absorption Rate
- Key factors include alcohol strength, food presence, carbonation, other beverage ingredients, emotions, and gender.
- High alcohol-concentration beverages are absorbed quickly; however, excess 100-proof alcohol absorbs more slowly due to stomach irritation.
- Food slows absorption by coating the stomach and diluting alcohol rather than soaking it up.
Time Estimates
- Absorption estimates: 20-40 minutes on an empty stomach, 60-90 minutes on a full stomach.
- Carbonation accelerates alcohol absorption.
Emotional Effects
- Strong emotions like anger or stress can quicken the absorption of alcohol from the stomach.
Gender Differences
- Women have less alcohol dehydrogenase, the enzyme responsible for breaking down alcohol, leading to up to 30% more alcohol absorbed in their bloodstream compared to men.
Consumption Rate
- Faster alcohol consumption correlates with quicker and greater effects; larger drinks enhance effects.
Alcohol Elimination
- Average alcohol elimination rate is approximately 0.015 BAL per hour.
- Despite ceasing drinking, BAL may continue to rise temporarily.
Perception of Sobriety
- After drinking, individuals may perceive themselves as more sober than they actually are, influenced by previous impairment levels.
Drug Administration Methods
- Injection: Intravenous injection provides instant entry into the bloodstream.
- Swallowing: Absorption rate depends on drug type and food in the stomach.
- Smoking: Transfers substances to the brain rapidly, faster than injection or swallowing.
- Inhaling: Similar to smoking, resulting in quick absorption and action.
- Higher active ingredient percentage in a drug generally leads to faster bloodstream delivery.
Drug Elimination
- Drugs are metabolized or excreted; majority eliminated via kidneys in urine, some through saliva, sweat, or exhalation.
- Elimination rates vary significantly based on drug type and individual health conditions.
Summary of Alcohol Absorption
- Key points to remember: 70%-80% of alcohol absorbed in the small intestine; food slows absorption; strong emotions increase absorption rate; gender affects absorption efficiency.
