1) I am a big fan of evolutionary medicine --> the study of human evolution and how it can be harnessed for the practice of medicine.
I recently went in for a deep dive into an important topic --> HYPERURICEMIA
Here is what I learnt!
2) Uric acid is the endproduct of purine metabolism in humans --> this is an exception among mammals!
Why does this happen?
1. Lack of uricase 2. Avid renal reabsorption of uric acid
3) Why happened to uricase?
This ancient enzyme, present since bacteria, accumulated a number of mutations approx 10-30 million years ago and gradually lost its function in humans, some higher primates and some New World monkeys.
1) I'm no expert but the Dolo 650 controversy is either a meaningless or a malignant one.
PCM is an OTC drug --> it is almost never the only drug in a prescription.
Why?
2) PCM doesn't provide any significant analgesia unless you are taking 2-3 gm/day.
Its good for the myalgia and arthralgia of febrile illnesses especially if NSAIDs are contraindicated --> like dengue which has a risk of thrombocytopenia.
3) For everything beyond this, you will need an adequate dose of an NSAID +/- local or systemic glucocorticoid therapy --> even DMARDs if its rheumatological!
Most patients in India don't go to a doctor for mild aches and pains --> they will buy PCM directly!
