๐Ÿ”ฌ Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionHydrochlorothiazide: Well absorbed orally, bioavailability 65-75%. Olmesartan: Rapidly absorbed, absolute bioavailability 26%.
DistributionHydrochlorothiazide: Vd 3-4 L/kg. Olmesartan: Vd 17 L.
Protein BindingHydrochlorothiazide: 40-68% bound to albumin. Olmesartan: >99% bound to plasma proteins.
MetabolismHydrochlorothiazide: Not metabolized. Olmesartan: Metabolized by intestinal esterases to active metabolite; minimal hepatic metabolism.
Half-LifeHydrochlorothiazide: 6-15 hours. Olmesartan: 10-15 hours.
ExcretionHydrochlorothiazide: Primarily renal (70% unchanged). Olmesartan: Biliary (50-80%) and renal (10-20%).
BioavailabilityHydrochlorothiazide: 65-75%. Olmesartan: 26%.
Onset of ActionHydrochlorothiazide: 2 hours. Olmesartan: 1-2 hours.
Peak Plasma TimeHydrochlorothiazide: 1-5 hours. Olmesartan: 1-2 hours.
Duration of ActionHydrochlorothiazide: 6-12 hours. Olmesartan: 24 hours.

How It Works

Hydrochlorothiazide inhibits sodium reabsorption in distal convoluted tubule, reducing plasma volume. Olmesartan blocks angiotensin II AT1 receptors, causing vasodilation and reduced aldosterone secretion.

Mechanism Steps

1Hydrochlorothiazide inhibits Na+/Cl- cotransporter in distal convoluted tubule, reducing sodium and water reabsorption.
2Increased sodium delivery to distal tubule enhances potassium and hydrogen excretion.
3Reduced plasma volume decreases cardiac output and blood pressure.
