Why in news: UPSC included Fixed-Dose Combinations (FDCs) in its Prelims syllabus due to concerns over irrational drug combinations and regulatory oversight.
Fixed-dose combinations (FDCs) contain two or more active ingredients in a single formulation. A combination is deemed 'irrational' if there is no scientific evidence that the ingredients work better together than separately.
Prelims pointers (3)
S&TFDCs: Formulations containing two or more active ingredients in a single product.
FactIrrational FDCs: Combinations lacking scientifically established rationale for synergistic therapeutic effects.
BodyRegulatory oversight: Drug authorities review and prohibit unsafe or irrational formulations in India.
Mains angle
Q. Critically analyze the regulatory challenges in monitoring Fixed-Dose Combinations (FDCs) in India and suggest measures to ensure rational drug usage.
Regulatory oversight gap: Difficulty in monitoring thousands of FDC variants for clinical efficacy and safety.
Public health risk: Proliferation of irrational combinations leading to potential drug resistance and adverse reactions.
Policy trade-off: Balancing ease of patient compliance (single pill) against the necessity of evidence-based pharmacological synergy.
