Introduction to pharmacology

Osmosis from Elsevier2 minutes read

Pharmacology involves studying medications to combat diseases, with new medications going through three steps before approval and receiving multiple names. Medications interact with the body through pharmacokinetics and pharmacodynamics, with the therapeutic index determining safety based on dose ratios.

Insights

  • Pharmacology involves studying medications and chemical compounds to create drugs for treating diseases like infections, cancer, heart failure, and depression.
  • The development of a new medication involves Discovery, Pre-clinical research, and Clinical development, with clinical trials in four phases to ensure safety and effectiveness, culminating in the medication receiving chemical, generic, and brand names after approval.

Recent questions

  • What is pharmacology?

    The field of pharmacology involves studying medications and chemical compounds that interact with living systems to produce specific effects. Pharmacologists work to develop new medications to combat various diseases like infections, cancer, heart failure, and depression.

  • How are new medications developed?

    New medications go through three main steps in their development process: Discovery, Pre-clinical research, and Clinical development. Clinical trials are then conducted in four phases to ensure the safety and efficacy of the medication before it can be approved for use.

  • What names does a medication receive upon approval?

    Once a medication is approved, it receives three names: a chemical name used for scientific studies, a generic name for health professionals, and one or more brand names from pharmaceutical companies for marketing purposes.

  • How do medications interact with the body?

    Medications interact with the body through pharmacokinetics, which involves their movement and modification within the body, and pharmacodynamics, which refers to their effects on the body. The therapeutic index of a medication indicates its safety based on the ratio between toxic and effective doses.

  • What is the purpose of clinical trials?

    Clinical trials are conducted in four phases to ensure the safety and efficacy of a new medication before it is approved for use. These trials help researchers gather data on the medication's effects, side effects, and overall performance in different populations.
