Diclofenac Potassium 50 mg and Serratiopeptidase 10 mg Tablets and its Mechanism of action

Description of Serratiopeptidase 10Mg + Diclofenac Potassium 50Mg Tablets is a combination of the two pharmacological classes Diclofenac Potassium and Serratiopeptidase, which is used to alleviate pain. Diclofenac Potassium is a non-steroidal anti-inflammatory medicine (NSAID) that acts by preventing the release of pain-causing chemical messengers in the brain (redness and swelling). Serratiopeptidase is an enzyme that aids healing by degrading aberrant proteins at the site of inflammation.

Diclofenac Potassium is a non-steroidal anti-inflammatory agent (NSAID) with antipyretic and analgesic actions.

Serratiopeptidase is a proteolytic enzyme (protease) produced by enterobacterium Serratia sp. E-15 used in the prevention of pain and swelling.

For the treatment of primary dysmenorrhea.

For the treatment of mild to moderate pain.

For the relief from the signs and symptoms of osteoarthritis.

For the relief from the signs and symptoms of rheumatoid arthritis.

Chronic inflammation.

Headaches, muscle, and joint pain.

Serious diseases like cancer and heart disease.

Superficial thrombophlebitis.

Postoperative & traumatic swelling.

Acute or chronic ear, nose, or throat disorder.

Uses

Diclofenac Potassium+Serratiopeptidase Tablet is a combination of medications intended to relieve pain, inflammation, and swelling in the short term. It prevents the release of chemical messengers in the brain that alerts us to the presence of pain. Back pain, toothache, periods of pain, earache, throat pain, and arthritis pain are all efficiently relieved by it.

Mechanism of action

Diclofenac inhibits cyclooxygenase-1 and -2, the enzymes responsible for the production of prostaglandin (PG) G2 which is the precursor to other PGs. These molecules have broad activity in pain and inflammation and the inhibition of their production is the common mechanism linking each effect of diclofenac.

PGE2 is the primary PG involved in the modulation of nociception. It mediates peripheral sensitization through a variety of effects. PGE2 activates the Gq-coupled EP1 receptor leading to increased activity of the inositol trisphosphate/phospholipase C pathway. Activation of this pathway releases intracellular stores of calcium which directly reduces the action potential threshold and activates protein kinase C (PKC) which contributes to several indirect mechanisms. PGE2 also activates the EP4 receptor, coupled to Gs, which activates the adenylyl cyclase/protein kinase A (AC/PKA) signaling pathway. PKA and PKC both contribute to the potentiation of transient receptor potential cation channel subfamily V member 1 (TRPV1) potentiation, which increases sensitivity to heat stimuli. They also activate tetrodotoxin-resistant sodium channels and inhibit inward potassium currents. PKA further contributes to the activation of the P2X3 purine receptor and sensitization of T-type calcium channels. The activation and sensitization of depolarizing ion channels and inhibition of inward potassium currents serve to reduce the intensity of stimulus necessary to generate action potentials in nociceptive sensory afferents. PGE2 acts via EP3 to increase sensitivity to bradykinin and via EP2 to further increase heat sensitivity. Central sensitization occurs in the dorsal horn of the spinal cord and is mediated by the EP2 receptor which couples to Gs. Pre-synaptically, this receptor increases the release of pro-nociceptive neurotransmitters glutamate, CGRP, and substance P. Post-synaptically it increases the activity of AMPA and NMDA receptors and produces inhibition of inhibitory glycinergic neurons. Together these lead to a reduced threshold of activating, allowing low-intensity stimuli to generate pain signals. PGI2 is known to play a role via its Gs-coupled IP receptor although the magnitude of its contribution varies. It has been proposed to be of greater importance in painful inflammatory conditions such as arthritis. By limiting sensitization, both peripheral and central, via these pathways NSAIDs can effectively reduce inflammatory pain.

PGI2 and PGE2 contribute to acute inflammation via their IP and EP2 receptors. Similarly to β adrenergic receptors these are Gs-coupled and mediate vasodilation through the AC/PKA pathway. PGE2 also contributes by increasing leukocyte adhesion to the endothelium and attracting the cells to the site of injury.17 PGD2 plays a role in the activation of endothelial cell release of cytokines through its DP1 receptor.11 PGI2 and PGE2 modulate T-helper cell activation and differentiation through IP, EP2, and EP4 receptors which is believed to be an important activity in the pathology of arthritic conditions. By limiting the production of these PGs at the site of injury, NSAIDs can reduce inflammation.

PGE2 can cross the blood-brain barrier and act on excitatory Gq EP3 receptors on thermoregulatory neurons in the hypothalamus.17 This activation triggers an increase in heat-generation and a reduction in heat-loss to produce a fever. NSAIDs prevent the generation of PGE2 thereby reducing the activity of these neurons.
