Adverse Drug Reactions​

Understanding pharmacology helps pharmacists identify and manage potential adverse reactions to medications.

Pharmacy Law and Ethics​

Pharmacists must adhere to strict laws and ethical guidelines in their professional practice.

  • Controlled Substances Act
  • HIPAA regulations
  • Prescription requirements

Ethical Considerations​

  • Confidentiality
  • Patient autonomy
  • Non-maleficence (do no harm)
  • Beneficence (do good)
  • Justice

Professional Organizations​

Pharmacists often belong to organizations like the American Pharmacists Association (APhA) to stay updated on legal and ethical standards.

Conclusion​

Pharmacy is a dynamic and vital profession that requires continuous learning and adaptation. This documentation site aims to provide comprehensive information to support students and practitioners in their journey through pharmacy education and practice.​
