*Pharmacology Cheat Sheet covering key drug classifications, mechanisms, and nursing considerations.* *📌 Basic Pharmacology Notes* 1️⃣ Drug Classifications & Examples *🔹 Analgesics (Pain Relievers)* Opioids: Morphine, Fentanyl, Oxycodone NSAIDs: Ibuprofen, Aspirin, Diclofenac Acetaminophen (Paracetamol) *🔹 Antibiotics (Infection Fighters)* Penicillins: Amoxicillin, Ampicillin Cephalosporins: Ceftriaxone, Cephalexin Macrolides: Azithromycin, Erythromycin Aminoglycosides: Gentamicin, Tobramycin *🔹 Cardiovascular Drugs* Beta-blockers: Metoprolol, Propranolol ACE Inhibitors: Lisinopril, Enalapril Calcium Channel Blockers: Amlodipine, Verapamil Diuretics: Furosemide, Spironolactone *🔹 CNS Drugs* Benzodiazepines (Sedatives): Diazepam, Lorazepam Antidepressants: Fluoxetine, Sertraline Antipsychotics: Haloperidol, Olanzapine Antiepileptics: Phenytoin, Valproate *🔹 Respiratory Drugs* Bronchodilators: Salbutamol, Theophylline Corticosteroids: Prednisolone, Budesonide *🔹 Endocrine Drugs* Insulin (Diabetes): Regular, NPH, Glargine Thyroid Medications: Levothyroxine (Hypothyroidism), Methimazole (Hyperthyroidism) *🔹 Gastrointestinal Drugs* Proton Pump Inhibitors (PPIs): Omeprazole, Pantoprazole Antiemetics: Ondansetron, Metoclopramide Laxatives: Lactulose, Bisacodyl *📌 Pharmacokinetics & Pharmacodynamics* ✅ Pharmacokinetics (How drugs move in the body) ADME: 🔹 Absorption: How the drug enters the bloodstream 🔹 Distribution: How it spreads in tissues 🔹 Metabolism: How the liver processes it 🔹 Excretion: How it leaves the body (urine, feces) ✅ Pharmacodynamics (How drugs work on the body) 🔹 Agonists – Activate receptors (e.g., Morphine on opioid receptors) 🔹 Antagonists – Block receptors (e.g., Naloxone blocks opioids) *📌 Nursing Considerations for Safe Drug Administration* 🩺 "6 Rights of Medication Administration" ✅ Right Patient – Verify name & ID ✅ Right Drug – Check the prescription ✅ Right Dose – Confirm safe dosage ✅ Right Route – Oral, IV, IM, etc. ✅ Right Time – Follow schedule ✅ Right Documentation – Record administration *🔔 Common Drug Interactions & Precautions* ⚠ Avoid mixing NSAIDs with anticoagulants (↑ bleeding risk) ⚠ No grapefruit juice with statins (↑ toxicity risk) ⚠ Monitor potassium with diuretics (Hypokalemia/Hyperkalemia) ⚠ Insulin + Beta-blockers = Hypoglycemia risk *PTB NURSE ACADEMY* https://whatsapp.com/channel/0029VaLlVmwAe5VsuZFOUW0t
