Chapter overview
Inflammation is the body’s protective response to injury or infection. Acute inflammation has vascular changes, namely vasodilation and increased vessel permeability, and cellular changes in which neutrophils and later macrophages move into the tissue. Chemical mediators such as histamine, prostaglandins, bradykinin and cytokines control these events. The classical signs are redness, heat, swelling, pain and loss of function. Chronic inflammation lasts longer, and repair occurs through regeneration or fibrosis, depending on the tissue and the extent of damage.
Key points on inflammation and repair
- Acute and chronic inflammation
- Vascular and cellular events of inflammation
- Chemical mediators of inflammation
- Systemic effects of inflammation
- Repair by regeneration and fibrosis
Relevance to pharmacy practice
Anti-inflammatory drugs act on these steps. NSAIDs block prostaglandin synthesis through cyclooxygenase, antihistamines block histamine receptors, and corticosteroids suppress many inflammatory mediators. Understanding the mediators explains both the benefits and side effects of these drugs, such as gastric irritation with NSAIDs. Pharmacists use this knowledge to advise on pain, fever, allergy and wound care in everyday practice.
Frequently asked questions
What are the cardinal signs of inflammation?
Redness, heat, swelling, pain and loss of function.
Which chemical mediators are involved in inflammation?
Histamine, prostaglandins, leukotrienes, bradykinin and cytokines among others.
How do NSAIDs reduce inflammation?
They inhibit cyclooxygenase enzymes, reducing prostaglandin production and therefore pain, fever and swelling.
Quick revision checklist
Before moving on, check that you can do each of the following without looking at your notes. Use this list on inflammation and repair as a self-test: tick a statement only when you can answer it aloud. Revisit any statement you cannot answer, then re-read the matching section of the PDF. Repeating this cycle two or three times before an exam builds the recall and confidence you need for both theory papers and viva.
- I can explain: acute and chronic inflammation
- I can explain: vascular and cellular events of inflammation
- I can explain: chemical mediators of inflammation
- I can explain: systemic effects of inflammation
- I can explain: repair by regeneration and fibrosis
Study and exam tips
Read the key points on inflammation and repair first, then study the PDF notes and redraw the main diagrams from memory. Link each concept to a drug or clinical example, and revisit the chapter before your internal and university examinations. Short daily revision works better than one long session. For additional reading, see the NCBI Bookshelf.
In B.Pharm examinations, short answer questions usually ask for definitions, classifications and labelled diagrams, while long answers on inflammation and repair ask for detailed descriptions with examples. Learn the headings in the order given in your syllabus, and add one clinical or drug-related example to each long answer to earn extra marks.
This post is part of the free B.Pharm Guru notes for the first semester. Every chapter of Human Anatomy, Physiology and Pathophysiology I has a short summary, key points and a downloadable PDF written for the B.Pharm course, so you can revise quickly or study in depth.
