Management of Pain and Inflammation

Pain affects a large population worldwide.

Potentially dangerous stimuli causing pain need to be reported immediately for our well-being. Management of pain by traditional therapies involve use of NSAIDs, opoids and antidepressants. These have low therapeutic indexes and undesirable side effects. They are often relatively ineffective in treating chronic pain. Need to evolve new molecules which are selective, possess high therapeutic index and few side-effects, if any.

COOH

COX-1 COX-2

NSA ID’s

Inhibitors include:Aspirin,Ibuprofen & IndomethacinInhibition may lead to Gastric ulcers,Kidney damages

Inhibitors includeNimesulide, NS-398.No known side-effects

Pain is caused by the effects of these prostaglandins which are released in the

inflammatory process.

ProstacyclinsProstaglandins

OUR WORK DEALS AT TWO LEVELS

Producing oral drugs which can scavenge toxic radicals

(because enzymes are ineffective by oral/I.p. routes.

Creating new COX-2 inhibitors which are effective in low doses.

Immunomodulation

• Concept and Definition: Immunomodulators are Biological Response Modifiers (BRM), used to treat cancer, exert their anti-tumor effects by improving host defense mechanisms against tumor (Encyclopedia Britannica).

• Immunostimulation in drug-induced immunosuppression and immunosuppression in experimental hyper-reactivity model by the same preparation can be said to be true immunomodulation.

Treatment with few selected test preparations resulted in :• Immunostimulatory activity in tumor-free animals receiving or not

receiving anticancer drugs.

• Protection from toxic side effects viz. myelo, immuno- suppression without compromising or interference with anticancer activity and this activity was dose dependent.

• Treatment with these candidate drugs will be important in development of supportive / adjuvant treatment to cancer therapy to avoid untoward effects.
