๐Ÿ”ฌ Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionAtorvastatin is rapidly absorbed after oral administration; peak plasma concentrations occur within 1-2 hours. Vitamin D3 is well absorbed in the small intestine.
DistributionAtorvastatin is highly distributed to tissues; vitamin D3 is distributed to fat and muscle tissues.
Protein BindingAtorvastatin: โ‰ฅ98% bound to plasma proteins. Vitamin D3: bound to vitamin D-binding protein.
MetabolismAtorvastatin: extensively metabolized by CYP3A4 to active ortho- and para-hydroxylated metabolites. Vitamin D3: hydroxylated in liver to 25-hydroxyvitamin D3.
Half-LifeAtorvastatin: approximately 14 hours (parent drug); active metabolites: 20-30 hours. Vitamin D3: 2-3
ExcretionAtorvastatin: primarily biliary excretion (feces); less than 2% excreted in urine. Vitamin D3: excreted in bile and feces.
BioavailabilityAtorvastatin: approximately 14% (low due to first-pass metabolism). Vitamin D3: well absorbed.
Onset of ActionAtorvastatin: within 2 weeks for lipid-lowering effect. Vitamin D3: variable.
Peak Plasma TimeAtorvastatin: 1-2 hours. Vitamin D3: 12-24 hours.
Duration of ActionAtorvastatin: up to 24 hours (once-daily dosing). Vitamin D3: weeks to months.

How It Works

Atorvastatin competitively inhibits HMG-CoA reductase, reducing cholesterol synthesis; increases LDL receptor expression. Vitamin D3 enhances calcium absorption and bone mineralization.

Mechanism Steps

1Atorvastatin competitively inhibits HMG-CoA reductase, the rate-limiting enzyme in cholesterol biosynthesis.
2Reduced intracellular cholesterol leads to upregulation of LDL receptors on hepatocytes.
3Increased LDL receptor expression enhances clearance of LDL-C from plasma.
