Investigate and assess the effectiveness of pharmaceuticals

Investigate and assess the effectiveness of pharmaceuticals as treatment strategies for the control of infectious disease, for example:

  • Antivirals
  • Antibiotics

Effectiveness of antivirals for treatment of infectious disease:

  • Antivirals are used to treat a variety of viral diseases.
  • Most antivirals are virus specific but there are some antivirals which are broad-spectrum, meaning that the same type of antiviral can be used to treat many different types of viral diseases.
  • Antivirals can reduce symptoms and can lessen the time a virus is prevalent in a person.
  • Antivirals can also reduce possibilities of developing severe illness and also reduce chances of the specific viral disease to turn lethal for that patient.

Effectiveness of antibiotics for treatment of infectious disease:

  • Antibiotics are widely used to treat diseases that are caused by bacteria.
  • They usually function by killing or inhibiting the growth of bacteria.
  • Antibiotics are used in surgical procedures to avoid infections.
  • They have an important role in dental antibiotic prophylaxis where their use may prevent bacteremia and consequent infective endocarditis.
  • Most antibiotics target the pathogenic bacterial cells rather than the human cells and thus have very limited side-effects.
  • Prolonged exposure to antibiotics might make the pathogens resistant towards the drugs which will not be beneficial for treatment.
