M2A4 57344 pill mechanism of action

Acetaminophen is thought to act primarily in the central nervous system, where it inhibits the prostaglandins synthesis by inhibiting COX-1 (cyclooxygenase-1), COX-2, and COX-3 enzymes.

Unlike NSAIDs, acetaminophen does not inhibit cyclooxygenase in peripheral tissues and, thus, has no peripheral anti-inflammatory affects.

While aspirin acts as an irreversible inhibitor of COX and directly blocks the enzyme’s active site, studies have found that acetaminophen indirectly blocks COX, and that this blockade is ineffective in the presence of peroxides.

This might explain why acetaminophen is effective in the central nervous system and in endothelial cells but not in platelets and immune cells which have high levels of peroxides.

Studies also report data suggesting that acetaminophen selectively blocks a variant of the COX enzyme that is different from the known variants COX-1 and COX-2.

This enzyme is now referred to as COX-3. Its exact mechanism of action is still poorly understood, but future research may provide further insight into how it works.

The antipyretic properties of acetaminophen are likely due to direct effects on the heat-regulating centers of the hypothalamus resulting in peripheral vasodilation, sweating and hence heat dissipation.

M2A4 57344 pill pharmacokinetics

Acetaminophen, when taken orally, shows complete and raid absorption. It shows 25% protein binding. 40 to 50% does of acetaminophen undergoes glucuronidation whereas 30-35% of the dose undergoes sulfation.

A small percentage of acetaminophen is oxidized by CYP2E1 to form N-acetyl-p-benzoquinone imine (NAPQI), a toxic metabolite which is then conjugated to glutathione and excreted renally.

Studies suggest that CYP3A4 and CYP2E1 are the primary cytochrome P450 isozymes responsible for the generation of toxic metabolites.

After conjugation, approximately 80% of the acetaminophen is excreted in the urine and around 3% excreted unchanged in the urine. The half-life of acetaminophen is 1 to 4 hours.

How long M2A4 57344 pill stays in the system?

The half-life of acetaminophen is 4 hours which means that half of this drug is out from the body in 4 hours.

The total elimination time of a drug is five times to that of the half-life of a drug. Therefore it will be completely excreted from the body in one day.
