Power ache, can final for weeks, months, or years and is commonly related to circumstances like arthritis, neuropathy, or fibromyalgia. Nociplastic ache is attributable to altered central nervous system processing with out clear tissue or nerve injury. Seen in circumstances like fibromyalgia, it includes elevated central sensitivity to ache.1, 2, 3
Ache modulation includes excitatory (e.g., glutamate) and inhibitory (e.g., GABA, endorphins) neurotransmitters. Power ache usually includes sensitisation, the place neurons turn into hyper-responsive, resulting in amplified ache, even with minimal or no new stimuli.1, 2, 3
Ache is among the commonest causes individuals search medical consideration, and over-the-counter (OTC) analgesia are ceaselessly used for a variety of delicate to reasonable ache circumstances. Understanding the kind and supply of ache is essential when selecting analgesia.4, 5, 6
Two main courses of OTC ache relievers are nonsteroidal anti-inflammatory medication (NSAIDs) and Paracetamol, every with distinct mechanisms of motion, advantages, and dangers.

Paracetamol’s precise mechanism shouldn’t be totally understood however is assumed to work centrally, by inhibiting COX enzymes within the mind, and presumably by way of serotonergic pathways concerned in ache modulation.4, 5, 6, 7
Though usually thought-about protected at really useful doses, paracetamol will be poisonous to the liver in excessive doses. It is very important keep away from exceeding the each day really useful dose, notably as a result of paracetamol is commonly an ingredient together drugs for chilly, flu, and allergy signs.

Mixed in a exact components, for instance Easolief DUO, these drugs can present more practical and longer-lasting reduction than both drug alone. Easolief DUO is clinically confirmed to supply 80 per cent extra ache reduction than the identical each day dose of normal paracetamol alone.8 Easolief DUO additionally has sooner onset of motion than the equal OTC dose of ibuprofen alone; it acts over 15 per cent sooner.8
With Easolief DUO you possibly can cut back the each day tablet consumption for sufferers from 14 if alternating between paracetamol and ibuprofen, to solely six tablets. The dosage regime is way easier as sufferers solely have to recollect to take 1-2 tablets each six hours threetimes a day (no more than six tablets in any 24 hour interval). That is extra handy and in addition helps keep away from confusion and threat of over/below dosing. One other good thing about Easolief DUO is that it doesn’t include opiates.
