The document provides information about urinary tract infections (UTIs). It discusses the epidemiology, etiology, signs and symptoms, pathogenesis, classification, and treatment of UTIs. It notes that UTIs are commonly caused by bacteria like E. coli and can affect the kidneys (pyelonephritis), bladder (cystitis), or urethra (urethritis). Common signs include pain or burning during urination. Treatment involves antibiotics like sulfonamides, nitrofurantoin, fluoroquinolones, and cephalosporins which can be bacteriostatic or bactericidal.
3. ANTI- INFECTIVES
- Anti-infective are drug that can either kill an
infectious agents or inhibit it from spreading.
- Anti-infectives include
Antibiotics and Antibacterial.
Antifungal.
Antiviral.
Antiprotozoals &
Anthelmintis. 3
6. GENERAL INTRODUCTION:
A urinary tract infection (UTI) is an infection in any
part of urinary system – kidney, ureters, bladder and
urethra.
It is define as the presence of at least 1 lakh bacteria
per ml of urine (normal bacterial count=1000 per ml
of urine).
Most infections involve the lower urinary tract the
bladder and the urethra.
It is common disorder at all ages in both males and
females. 6
7. EPIDEMOLOGY:
UTI is the 2nd most common infections present
in community practices.
World wide, about 150 million people are
diagnosed with UTI each year .
Prevalence 35% of healthy women suffer
symptoms of UTI at some time in their life.
7
8. ETIOLOGY:-
The causative organism causing UTI are:-
E.Coli , Pseudomonas aeroginosa,
Streptococcus faecalis, Staphylococcus
epidermis and Proteus mirabilis.
Waiting for long to urinate.
Sexual transmitted diseases [STD] like
gonorrhea causes urethritis .
Presence of tumor/ stones/ foreign bodies in
urinary tract.

affected
Signs and Symptoms
Kidneys (acute Pyelonephritis) Upper back and side (flank) pain
High fever
Shaking and chills
Nausea
Vomiting.
Bladder (cystitis) Pelvic pressure
Lower abdomen discomfort
Frequent painful urination
Blood in urine.
Urethra (urethritis) Burning with urination
Discharge. 11
12. PATHOGENESIS
• In many cases, bacteria first travel to the
urethra. When bacteria multiply, an infection can
occur. An infection limited to the urethra is called
urethritis.
• If bacteria move to the bladder and multiply, a
bladder infection, called cystitis.
• If the infection is not treated promptly, bacteria
may then travel further up the ureters to multiply
and infect the kidneys. A kidney infection is
called pyelonephritis. 12
16. SULPHANAMIDES
• The term ‘sulfonamide’ is employed as generic name for
derivatives of para aminobenzene sulfonamide (sulfanilamide)
• 1st effective chemotherapeuutic agent ,for the prevention and
use of bacterial infections in man.
• DOMAGK(1932) discovered that prontosil protected mice
against streptococcal infections.
CLASSIFICATION:-
1. Poorly absorbed , locally acting:- sulphasalazine
2. Well absorbed , rapidly excreted:- sulphadiazine
3. Readily absorbed, medium rate of excretion:- sulphafurazole
4. Readily absorbed, slowly excreted:- sulphametopyrazine
16
17. SULPHAMETHOXAZOLE/
TRIMETROPRIM
PROPERTIES:
o It is a white, odourless , crystalline powder and is bitter in taste .It is
employed principally in lower urinary track & systemic infections
caused by E.COLI.
USES:-
• Nocardia (DOC), Mycobacteria, Gram –ve infections, Gram +ve
infections, Fungus – Pneumocystis carinii, Protozoa – Toxoplasma
gondii.
• Sulfonamides are conjugated in the liver and their metabolites are
excreted in the kidney which can cause crystalluria.
They are high protein bounding drugs. Can cause kernicterus in
neonates.
• It is used in treatment of several infections including AIDS. 17
18. M.O.A
They compete with PABA to
bind to dihydropteroate
synthetase and inhibit
conversion of PABA and
dihydropteroate diphosphate to
dihydrofolic acid, or
dihydrofolate. Inhibiting the
production of dihydrofolate
intermediate interferes with the
normal bacterial synthesis of
folic acid (folate). Since it
inhibits bacterial growth,
sulfamethoxazole is considered
a bacteriostatic antibiotic. 18

21
22. Continued….
MOA: -
The MOA of nitrofuratonin is unique and complex the
drug works by damaging bacteria DNA since it reduced
form is highly reactive. This is made possible by rapid
reduction of nitrofuratonin inside the bacterial cell by
flavoproteins to multiply reactive intermediators that acts
on ribosomal proteins. The broads mechanism of action
for this drug likely is responsible for the low development
of resistance to its effect as a drug effects many different
processes important to bacterial cells.
22
23. DOSAGE: -
Oral for adults :- 50-100 mg
every 6 hours with meals and at bed time .

• Cephalosporin's are discovered by G.Brotzu
of Sardinia made cultures from sea water at
a sewage, this might contain organisms
antagonistic to intestinal pathogens.

dihydrothiazine ring .
•They are water soluble and stable to
changes in PH and Temperature.

GUIDANCE PRINCIPLES
FOR THE USE OF CEPHALOSPORINS :
Cephalosporin's are expensive and should not be
used where an equally effective , alternative
antibiotic is available.

anaerobic infections .
None of them is effective against infectious by
enterococci (strep.fecalis)
