🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionFollowing intranasal administration, this medicine is rapidly absorbed through the nasal mucosa. Bioavailability is approximately 3% relative to subcutaneous administration. Peak plasma concentrations are achieved within 30 to 40 minutes.
DistributionThis medicine distributes primarily in the plasma and extracellular fluid. It does not appear to cross the blood-brain barrier significantly. Protein binding is approximately 30% to 40%.
Protein BindingApproximately 30% to 40% bound to plasma proteins.
MetabolismThis medicine is metabolized primarily in the kidneys and also in the liver and other tissues. The exact metabolic pathways are not fully characterized.
Half-LifeThe elimination half-life is approximately 43 minutes for the intranasal formulation.
ExcretionThis medicine and its metabolites are excreted mainly through the kidneys as inactive metabolites.
BioavailabilityThe bioavailability of intranasal calcitonin (salmon) is approximately 3% compared to subcutaneous administration.
Onset of ActionThe onset of action for lowering serum calcium is within 1 to 2 hours after intranasal administration.
Peak Plasma TimePeak plasma concentrations are reached within 30 to 40 minutes after intranasal administration.
Duration of ActionThe duration of action is approximately 6 to 12 hours for calcium-lowering effects, but the effect on bone turnover may last longer with regular use.

How It Works

This medicine works by binding to calcitonin receptors on osteoclasts, the cells responsible for bone resorption. This binding inhibits osteoclast activity and reduces the release of calcium from bones into the bloodstream. Additionally, it decreases renal tubular reabsorption of calcium and phosphate, leading to increased excretion of these minerals in urine. The overall effect is a reduction in bone turnover and a decrease in blood calcium levels.

Mechanism Steps

1
Binding to calcitonin receptors: This medicine binds to specific calcitonin receptors located on the surface of osteoclasts.
2
Inhibition of osteoclast activity: Binding leads to inhibition of osteoclast function, reducing bone resorption.
3
Decreased renal reabsorption: This medicine reduces renal tubular reabsorption of calcium and phosphate, increasing their urinary excretion.
4
Reduction in bone turnover: The combined effects result in decreased bone turnover and lower serum calcium levels.
