🌈 Medication Error and Drug Interaction: Types, Causes, LASA, TALMAN Lettering, Drug–Drug Interaction, Food–Drug Interaction, Pharmaceutical Interaction and Prevention Strategies
🌈 Introduction
🔷 Medication Error वह preventable mistake होती है जो medicine के prescribing, dispensing, administration, monitoring या use के दौरान होती है और patient को harm पहुँचा सकती है।
🔷 Drug Interaction वह condition होती है जिसमें एक drug दूसरी drug, food, disease, alcohol, smoking या chemical substance के effect को change कर देती है।
🌟 दोनों topics clinical pharmacy, hospital pharmacy, pharmacovigilance और patient safety के लिए अत्यंत महत्वपूर्ण हैं।
