Introduction Antiviral drugs are pharmacological agents that inhibit the replication of viruses within host cells. Unlike antibacterial drugs, which target cell wall or protein synthesis, antivirals act on specific stages of the viral life cycle, including attachment, entry, nucleic acid synthesis, protein processing, and viral release. Mechanism of Action of Antiviral Drugs is based on … Read more
Introduction Nutraceuticals, including vitamins, minerals, omega-3s, probiotics, polyphenols and herbal extracts, play an expanding role in preventing and managing health problems and diseases. For B. Pharm students, understanding mechanisms—antioxidant, anti-inflammatory, lipid‑lowering, insulin‑sensitizing, gut‑microbiota modulation—and clinical evidence is essential. Key topics include cardiovascular risk reduction (phytosterols, omega‑3), glycemic control (berberine, fiber), bone health (calcium, vitamin D), … Read more
Pharmacy Benefit Manager (PBM) audits are stressful because tiny “clerical errors” can trigger huge clawbacks and fines. The claim paid months ago can be reversed, sometimes for the full amount, because a field on the claim, a date on a label, or a missing signature does not match the record. PBMs argue that accuracy proves … Read more
Introduction Antiplatelet drugs are pharmacological agents that inhibit platelet aggregation, thereby preventing arterial thrombosis — a key contributor to myocardial infarction, ischemic stroke, and peripheral artery disease. Mechanism of Action of Antiplatelet Drugs involves blocking platelet activation pathways mediated by cyclooxygenase (COX-1), ADP receptors (P2Y₁₂), glycoprotein IIb/IIIa receptors, and thromboxane A₂ synthesis. Unlike anticoagulants, which … Read more
This concise guide covers the definition and classification of Functional Foods, Nutraceuticals and Dietary Supplements with emphasis on bioactive compounds, mechanisms, classification criteria, examples and regulatory aspects—key concepts for B. Pharm students. You will learn clear definitions, how functional foods differ from nutraceuticals and dietary supplements, classification by source and function (conventional, fortified, enriched, herbal, … Read more
High-Performance Thin-Layer Chromatography–Mass Spectrometry (HPTLC-MS) combines high-resolution planar chromatography with powerful mass spectrometric detection, offering a robust, cost-effective tool for pharmaceutical analysis. This technique integrates optimized stationary phases, automated sample application, precise development, selective derivatization, and direct coupling to mass spectrometry (ESI/APCI) via TLC‑MS interfaces. HPTLC‑MS enables qualitative identification, quantitative determination, impurity profiling, herbal fingerprinting, … Read more
Gas chromatography–tandem mass spectrometry (GC-MS/MS) is a powerful analytical platform used to separate, identify, and quantify volatile and semi-volatile compounds with high sensitivity and selectivity. This concise overview emphasizes GC-MS/MS instrumentation — injectors, capillary columns, transfer lines, ionization sources (EI and CI), collision cells, and triple‑quadrupole analyzers — and practical applications in pharmaceutical analysis, drug … Read more
LC-MS/MS: instrumentation and applications MCQs With Answer Liquid chromatography–tandem mass spectrometry (LC-MS/MS) is a cornerstone technique in pharmaceutical analysis, combining high-performance liquid chromatography with sensitive mass spectrometric detection. B. Pharm students should understand LC components (columns, mobile phases, gradient elution), ionization sources (ESI, APCI), mass analyzers (triple quadrupole, QTOF), and tandem MS modes (MRM/SRM, product … Read more
Hyphenated techniques combine a separation method with a spectroscopic or spectrometric detector to provide both qualitative and quantitative information. In pharmaceutical analysis, hyphenated techniques such as GC–MS, LC–MS, LC–MS/MS, CE–MS, LC–NMR and ICP–MS exploit principles of chromatographic separation plus mass spectrometric or spectroscopic identification to deliver high sensitivity, selectivity, and structural elucidation. Advantages include trace-level … Read more
Introduction: Liquid-liquid extraction is a fundamental separation technique in pharmaceutical analysis and drug formulation, involving partitioning of solutes between two immiscible liquid phases. Key concepts include partition coefficient, distribution ratio, solvent selection, phase separation, extraction efficiency, and back-extraction. Practical procedure steps—choice of extraction solvent, pH adjustment for ionizable drugs, multiple-stage extraction, drying agents, and solvent … Read more
