Medicines for infections
Unit 3
Point 4
Pages 50-51.

Introduction:
Enable medications to combat infectious diseases but do not produce an immune response against infection.

The drugs make us safer life and is one of the great advances in science.
Main drugs:
Antibiotics

Antivirals

Antibiotics:
The are chemicals.
They have got a biological origin.
Their discovery was a real revolution
struggle against infectious diseases.

And in 1920 ocurred a very important
discovery: the penecillin.
The penicillin:
Penicillin was discovered by Alexander Fleming.

It was develop by
Staphylococcus aureus
bacterium which had been contaminated by a fungus.

For this mediode penicillin later helped the development of other drugs development.
Amoxixilina
Ampicilina
Penicilina G
Benzatinica
Penicilina G sodica
And not only thanks to penicillin found other medications but were able create new molecules that have similiar effects, synthetic antibiotics
Antivirals:
For non-bacterial infectious diseases must use other medications.
The importance of some viral infections such as AIDS day rise to the efforts of antiviral drugs.
He can not eliminate the fact that virus but qeu handles the virus into the cells or cause its reproduction.
Information on Antiviral
Acyclovir discovery in 1974 by Howard
Schaeffer and Beauchamp Lilia in the
laboratories of Burroughs Wellcome &
Company (GlaxoSmithKline).

In 1982 the production of Acyclovir topical
began.
Antiviral Featuresl
• Are analogs of nucleic acids:
• Blocking adhesion and penetration:
• Inhibition of DNA synthesis
• Inhibition of protein synthesis
• Impaired maturation phase protein
Parts of the presentation
Types of drugs:
Antibiotics
Antiviral
Drug resistance:
Resistance to antibiotics
More resistant bacteria
Drug resistance
Resistance to antibiotics
More resistant bacteria
Resistance to antibiotics
:
2 types:
Mutation
Exchange of genes
Mutation
Their genetics training can vary spontaneously
It can lead to can survive the antibiotic
Exchange of genes
Propagation of more resistant bacterial strains
Causes:
Inadequate treatment
Use of other antibiotics in plants or animals
Prescription of antibiotics in excess and insufficiency
Discriminated sale of many drugs
Inadequate treatment
Use of other antibiotics in plants or animal
s
Sometimes infectious diseases can be displaced by plants or animals so here by this circumstance can recive some infectious diseases
If a bacterium gets a way to survive the antibiotic can pass this information to other bacteria
The End.
