What defines bioavailability (F), and what is the mathematical formula for calculating it from oral versus intravenous administration?

Bioavailability F is the fraction of a dose reaching systemic circulation unchanged: F = (AUCoral / Doseoral) / (AUCIV / DoseIV). IV administration has F = 1. To report a percentage, multiply F by 100; use the fraction, not the percentage, in loading- and maintenance-dose formulas.

How is apparent volume of distribution (Vd) calculated, and what does a large value imply?

Vd = amount of drug in the body / plasma drug concentration. A large apparent Vd means relatively little drug remains in plasma compared with the amount in the body, often because of tissue binding or partitioning. It is a proportionality constant, not a measured anatomical volume, and does not by itself prove lipophilicity.

What is the molecular target of beta-lactam antibiotics, and how do beta-lactamase inhibitors overcome bacterial enzymatic resistance?

Beta-lactam antibiotics bind penicillin-binding proteins and inhibit peptidoglycan cross-linking. Beta-lactamase inhibitors protect a partner antibiotic against susceptible enzymes, but their mechanisms and spectra differ. Clavulanate, sulbactam, and tazobactam are mechanism-based inhibitors; avibactam forms a reversible covalent complex with susceptible serine beta-lactamases. They do not overcome every resistance mechanism.

What is the mechanism of action of Vancomycin, and what is the pathophysiologic mechanism of 'Vancomycin Flushing Syndrome' (Red Man Syndrome)?

Vancomycin binds D-Ala-D-Ala termini of peptidoglycan precursors, inhibiting Gram-positive cell-wall synthesis. Vancomycin infusion reaction is usually rate-related, non-IgE-mediated histamine release. For the referenced IV product, infuse at no more than 10 mg/min and for at least 60 minutes, whichever requires longer. Stop and assess a suspected reaction; further management depends on severity and whether anaphylaxis is possible.

1. Per què el Record Actiu i la Repetició Espaiada funcionen per a Farmacologia

Dominar Farmacologia exigeix tant una comprensió conceptual sòlida com rapidesa i precisió per recordar definicions, principis, mecanismes i casos pràctics. Combinar el Record Actiu (Active Recall) amb la Repetició Espaiada elimina la falsa sensació de domini i fixa els coneixements de Farmacologia a la memòria a llarg termini.

Tot seguit trobaràs el full de ruta complet amb enllaços directes als jocs de targetes curats de Farmacologia a flashcards.world classificats per nivell de dificultat.

Nivell	Anvers (Pregunta / Terme)	Revers (Resposta / Explicació)
`basic`	What defines bioavailability (F), and what is the mathematical formula for calculating it from oral versus intravenous administration?	Bioavailability F is the fraction of a dose reaching systemic circulation unchanged: F = (AUC_oral / Dose_oral) / (AUC_IV / Dose_IV). IV administration has F = 1. To report a percentage, multiply F by 100; use the fraction, not the percentage, in loading- and maintenance-dose formulas.
`basic`	How is apparent volume of distribution (Vd) calculated, and what does a large value imply?	Vd = amount of drug in the body / plasma drug concentration. A large apparent Vd means relatively little drug remains in plasma compared with the amount in the body, often because of tissue binding or partitioning. It is a proportionality constant, not a measured anatomical volume, and does not by itself prove lipophilicity.
`intermediate`	What is the hemodynamic mechanism of ACE inhibitors in the renal glomerulus, and what causes the characteristic dry cough and angioedema?	ACE inhibitors (e.g., Lisinopril, Enalapril) block conversion of Angiotensin I to Angiotensin II, preferentially dilating the EFFERENT glomerular arteriole, which decreases intraglomerular capillary hydrostatic pressure and reduces proteinuria (protecting diabetic kidneys). ACE is identical to Kininase II; its inhibition prevents the degradation of Bradykinin and substance P, leading to dry cough and rare, life-threatening angioedema.
`intermediate`	How do Angiotensin Receptor Blockers (ARBs) differ pharmacologically from ACE inhibitors, and what is their clinical niche?	ARBs such as losartan and valsartan block angiotensin II AT1 receptors without inhibiting ACE (kininase II). They therefore do not inhibit bradykinin breakdown and cause less cough than ACE inhibitors. Angioedema is less common but can still occur, including in people with previous ACE-inhibitor-associated angioedema; it is not a zero-risk alternative.
`advanced`	What is the molecular target of beta-lactam antibiotics, and how do beta-lactamase inhibitors overcome bacterial enzymatic resistance?	Beta-lactam antibiotics bind penicillin-binding proteins and inhibit peptidoglycan cross-linking. Beta-lactamase inhibitors protect a partner antibiotic against susceptible enzymes, but their mechanisms and spectra differ. Clavulanate, sulbactam, and tazobactam are mechanism-based inhibitors; avibactam forms a reversible covalent complex with susceptible serine beta-lactamases. They do not overcome every resistance mechanism.

Vancomycin binds D-Ala-D-Ala termini of peptidoglycan precursors, inhibiting Gram-positive cell-wall synthesis. Vancomycin infusion reaction is usually rate-related, non-IgE-mediated histamine release. For the referenced IV product, infuse at no more than 10 mg/min and for at least 60 minutes, whichever requires longer.
