Scientific Explanation

The conversion between diclofenac and ibuprofen dosages is not a precise science, but it is based on an understanding of their pharmacokinetic and pharmacodynamic properties.

Pharmacokinetics

Pharmacokinetics refers to how the body absorbs, distributes, metabolizes, and eliminates a drug. Diclofenac and ibuprofen have different pharmacokinetic profiles, which can influence their relative potency.

• Absorption: Both diclofenac and ibuprofen are well-absorbed from the gastrointestinal tract, but the rate of absorption can vary depending on the formulation and individual factors.
• Distribution: Diclofenac and ibuprofen are distributed throughout the body and bind to plasma proteins. The extent of protein binding can affect the amount of free drug available to exert its effects.
• Metabolism: Diclofenac and ibuprofen are metabolized in the liver by different enzymes. Differences in metabolic pathways can influence how quickly the drugs are broken down and eliminated.
• Elimination: Both diclofenac and ibuprofen are primarily eliminated from the body through the kidneys. Impaired kidney function can prolong the elimination half-life of these drugs, potentially increasing the risk of side effects.

Pharmacodynamics

Pharmacodynamics refers to how a drug affects the body. Diclofenac and ibuprofen both inhibit cyclooxygenase (COX) enzymes, which are responsible for producing prostaglandins. However, they may have different affinities for COX-1 and COX-2 enzymes, which can influence their anti-inflammatory and analgesic effects.

• COX-1 Inhibition: COX-1 enzymes are involved in maintaining the normal lining of the stomach and regulating blood clotting. Inhibition of COX-1 can lead to gastrointestinal side effects, such as ulcers and bleeding.
• COX-2 Inhibition: COX-2 enzymes are primarily involved in inflammation and pain. Selective COX-2 inhibitors are designed to reduce pain and inflammation while minimizing gastrointestinal side effects.

Diclofenac is considered to be a relatively non-selective COX inhibitor, meaning that it inhibits both COX-1 and COX-2 enzymes. Ibuprofen is also a non-selective COX inhibitor, but it may have a slightly greater affinity for COX-1 enzymes.
