How Prescription Medications Work

How Prescription Medications Work

Each different prescription medicine operates through its mechanism according to its different active ingredient and therapeutic group.

Examples:

  • Lisinopril – works by altering the renin-angiotensin system to lower blood pressure.
  • Amlodipine- acts to relax blood vessels and therefore lowering blood pressure.
  • Atorvastatin-works by lowering amount of cholesterol produced by body.
  • Metformin- works on lowering glucose blood levels.
  • Levothyroxine – works as a body replacement therapy in situations where the thyroid hormone is low.
  • Albuterol- works by relaxing muscles surrounding the lungs allowing an easier way for breathing to occur.
  • Antibiotics work against any accessible bacteria that there is the susceptible strain and they are inactive in situations with viruses.

Every medicine has different requirements concerning the mechanism, dosage, treatment duration and necessary monitoring.
