Prostaglandins:
Hormone Like Substances which play a role in the Cell Metabolism.
Act as Chemical Mediators of the inflammatory response, increasing permeability (Vasodilatation) causing Inflammation.
Potentiate the effect of pain mediators (Histamine & Bradykinin) – They Sensitize the Pain Receptors.
They can cause PYREXIA by increasing their numbers due to an injection of a Pyrogen.
Mechanism of Action
Inhibits prostaglandin biosynthesis (Like All Other NSAIDS)
Blocks Prostaglandin Action by Blocking PG Receptor Cells. (UNIQUE ACTION)
PONSTAN FORTE Exerts a DOUBLE
BLOCKADE Action on Prostaglandins.
Pharmacokinetics and Metabolism
Well absorbed from the GIT.
Peak plasma concentrations 1 - 3 hours.
Rapid Onset of Action 30 min.
Pain Relief Maintained for 8 hours.
Extensively bounded to plasma proteins.
Metabolized by Gluco - conjugation in the liver.
> 50% is recovered in the urine as: unchanged drug or conjugated metabolites.
Indications
For the relief of pain in acute andchronic conditions including painof traumatic, arthritic or muscularorigin; primary dysmenorrhoea,
headache and dental pain.

Clindamycin, ampicillin, & cephalosporins were the 1st antibiotics associated
with CDAD ; the 2nd & 3rd generation cephalosp. , particularly cefotaxime,
ceftriaxone, cefuroxime & ceftazidime are now the agents most frequently
responsible for this condition … However all antibiotics , including
vancomycin & metronidazole (the agents most commonly used to treat
CDAD) have been found to carry a risk of subsequent CDAD ..

Adapted from HARRISON’S Internal Medecine – 16th Edition
All 3 generations of cephalosporins, macrolides, clindamycin, & intravenous
β-lactam/β-lactamase inhibitors were intermediate-risk antibiotics with
similar AHRs …… Administration of Fluoroquinolones emerged as the most
important risk Factor for CDAD in Quebec during an epidemic …
Clinical Infectious Diseases 2005 ; 41: 1254-60
by 2005 Infectious Diseases Society of America
We found that association between Fluoroquinolones and CDAD is stronger
than the association between clindamycin and CDAD … Thus, our study is
consistent with more recent reports that implicate Fluoroquinolone use as
risk factor for CDAD …Emerging Infectious Diseases, Vol 9, No 6, June 2003
Clindamycin was the highest-risk agent for CDAD in the 1970s … By the
late 1980s and through 1990s , cephalosporin antimicrobials… had become
the agents with the highest relative risk of CDAD …
