Notes

  • Lithium is a highly effective mood stabilizer, yet its precise mechanism of action remains scientifically debated.
  • Leading theories on Lithium's function suggest it influences inositol signalling and inhibits the GSK-3 enzyme, though these do not account for all observed effects.
  • General anesthetics have been used safely for over 150 years to induce unconsciousness, amnesia, and immobility, yet their molecular-level mechanism remains unclear.
  • High-temperature superconductors, discovered in the 1980s, lack a complete theoretical explanation, unlike conventional superconductors explained by BCS theory.
  • Metformin (Glucophage), a first-line type II diabetes treatment, has an incompletely understood mechanism, with research pointing toward effects on the gut microbiome and mitochondrial complex I.
  • Ketamine, a phencyclidine derivative used as surgical anesthesia, can alleviate severe depression within hours at sub-anesthetic doses, contrasting with SSRIs, though its full mechanism remains unknown.

Questions

  1. The persistence of 'black box' phenomena in medical science, where effective treatments are used without a complete understanding of their mechanisms, poses challenges for pharmacological advancement. Discuss the implications of this uncertainty for patient safety and the development of precision medicine in the Indian context. 150 words
