May raise the level of magnesium salts in the serum.

Alpha-Lipoic Acid

Alpha-Lipoic Acid may be less readily absorbed when taken with magnesium salts. Magnesium salts may be less readily absorbed when alpha-lipoic acid is present.

Bictegravir

Polyvalent Cation Containing Products may decrease the serum concentration of Bictegravir. Management: Administer bictegravir under fasting conditions at least 2 hours before or 6 hours after polyvalent cation containing products. Coadministration of bictegravir with or 2 hours after most polyvalent cation products is not recommended.

Bisphosphonate Derivatives

Polyvalent Cation Containing Products may decrease the serum concentration of Bisphosphonate Derivatives. Management: Avoid administration of oral medications containing polyvalent cations within: 2 hours before or after tiludronate/clodronate/etidronate; 60 minutes after oral ibandronate; or 30 minutes after alendronate/risedronate. Exceptions: Pamidronate; Zoledronic Acid.

Items containing polyvalent cations may lower the level of deferiprone in the serum. Treatment: Provide deferiprone at least four hours apart from oral drugs or dietary supplements containing polyvalent cations.

Dolutegravir

Magnesium salts may lower the level of dolutegravir in the serum. Treatment: Dolutegravir should be given at least two hours before or six hours after taking oral magnesium salts. While taking oral magnesium salts, provide the dolutegravir/rilpivirine combination product at least 4 hours before or 6 hours after.

Doxercalciferol

Magnesium salts' hypermagnesemic impact might be enhanced. While treating individuals who are also on doxercalciferol, take into account utilising an antacid or phosphate-binding medicine that doesn't contain magnesium. Serum magnesium concentrations should be carefully watched if magnesium-containing products must be taken with doxercalciferol.

Eltrombopag

Products containing polyvalent cations may lower the serum concentration of eltrombopag. Treatment: Provide eltrombopag at least two hours before or four hours after taking any oral medication containing polyvalent cations.

Gabapentin

Gabapentin's CNS depressive effects may be strengthened by magnesium salts. Magnesium sulphate at large doses administered intravenously or epidurally, in particular, may increase the CNS depressive effects of gabapentin. Magnesium salts may lower the level of gabapentin in the blood. Treatment: Provide gabapentin at least two hours after taking an antacid that contains magnesium. Keep a watchful eye on the patients for signs of a diminished response to gabapentin medication. If high dosage IV/epidural magnesium sulphate is given, keep an eye out for CNS depression.

Ginkgo Biloba

May enhance salicylates' anticoagulant effects. Management: Take into account alternatives to this agent combination. If you use salicylates and ginkgo biloba together, keep an eye out for any bleeding symptoms and indications, especially intracranial haemorrhage.

Herbs (Anticoagulant/Antiplatelet Properties) (eg, Alfalfa, Anise, Bilberry)

May intensify salicylates' harmful or hazardous effects. Bleeding could happen.

Hyaluronidase

Salicylates may reduce Hyaluronidase's ability to treat disease. Treatment: Standard doses of hyaluronidase may not produce the desired clinical response in patients receiving salicylates (especially at higher doses). Hyaluronidase may be needed at higher doses.

Magnesium salts may lower the level of mycophenolate in the serum. Treatment: Different doses of mycophenolate and magnesium salts taken orally. If mycophenolate and oral magnesium salts are taken at the same time, watch out for any diminished effects.

Nonsteroidal Anti-Inflammatory Agents (Nonselective)

May intensify salicylates' harmful or hazardous effects. The usage of this combination may raise your risk of bleeding. Salicylates' cardioprotective action may be reduced by nonsteroidal anti-inflammatory drugs (Nonselective). Salicylates may lower the serum level of non-steroidal anti-inflammatory drugs (NSAIDs) (Nonselective).

PenicillAMINE

Products containing polyvalent cations may lower the level of penicillAMINE in the serum. Treatment: Provide oral medications containing polyvalent cations and penicillamine at least an hour apart.

Phosphate Supplements

The serum content of supplements containing phosphate may be lowered by magnesium salts. Management: To reduce the importance of this interaction, administer oral phosphate supplements as far apart as you can from the administration of an oral magnesium salt. Exceptions: Pentahydrate of sodium glycerophosphate.

PRALAtrexate

Salicylates may raise the PRALAtrexate serum concentration. Salicylate dosages used for cardiovascular event prevention are unlikely to cause concern.

How to administer Magnesium salicylate?

Administer after meals with a full glass of water.


Mechanism of action of Magnesium salicylate:

  • By reversibly suppressing cyclooxygenase-1 (COX-1) enzymes via acetylation, it reduces inflammation, discomfort, and fever.
  • As a result, less prostaglandin A precursor and thromboxane B precursor are produced.

Absorption:

  • It is swiftly absorbed from the upper intestine and stomach.

Distribution:

  • It rapidly penetrates tissues and the majority of bodily fluids.

Protein binding:

  • Between 50% and 90% of the medication is bonded to albumin and other plasma proteins.

Metabolism:

  • When it enters the plasma, it first appears as salicylic acid, which is then enzymatically changed into salicyluric acid and salicylphenolic glucuronide.

Half-life elimination:

  • About 2 hours;
  • The half-life is increased with repeated dosing

Time to peak effect:

  • 1.5 hours

Excretion:

  • Urine
