Study Notes
Irregular Heartbeats and Treatments
- Antiarrhythmic Drugs: Medications like Mexiletine are utilized to treat irregular heartbeats (arrhythmias).
- Restoration of Rhythm: Certain drugs, such as Mexiletine, are specifically designed to restore normal heart rhythm in patients with arrhythmias.
Mexiletine
- Sodium Channel Blockade: Mexiletine works by blocking sodium channels in cardiac cells, thereby stabilizing the cardiac membrane and reducing excitability.
Paracetamol (Acetaminophen)
- Adverse Effects: Overdose or high doses of paracetamol can lead to liver damage, especially when combined with alcohol consumption.
- Therapeutic Effects: Paracetamol functions as both an analgesic (pain reliever) and antipyretic (fever reducer).
Metabolism of Paracetamol
- Liver Metabolism: Paracetamol is primarily metabolized in the liver, where it's processed through conjugation pathways.
Oral Contraceptives
- Therapeutic Benefits: Oral contraceptives offer key benefits, including regulation of menstrual cycles, reduction of menstrual pain, and prevention of pregnancy.
Other Key Points
- Analgesic and Antipyretic Drug: Paracetamol (Acetaminophen) serves as a common analgesic and antipyretic.
- Liver-Metabolized Drugs: Many medications, including paracetamol, undergo liver metabolism which is crucial for their elimination from the body.
