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!
4) No doctor will prescribe less than adequate analgesia for a patient in pain --> it is simply unthinkable.
So isolated PCM prescriptions are about as rare as the people who are willing to look beyond cheap media publicity --> it is for their benefit that I have posted this.
5) This review --> high quality evidence of analgesia is lacking for PCM.
Even then it required a minimum of 1 gm/day and provided only mild analgesia.
6) Excerpts from the above article --> adequate analgesia with PCM is impossible because at such high doses --> transient elevation of liver enzymes --> can easily lead to ALF in unmonitored patients.
7) PCM is safe and well tolerated drug --> especially when used in doses as seen in usual clinical practice --> it also lacks most of the adverse effects of NSAID unless its taken long term.
Its an adjunct.
All physicians use it --> but none rely on it only!
8) It is frankly illogical --> if one thinks that docs are dying to prescribe an off patent OTC painkiller with only modest efficacy --> that seasoned pharma executives will pay crores for something like this.
The foolishness, even if its is a conspiracy, boggles the mind!
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.
