Doxepin volume of distribution

Doxepin (DOX) and desmethyldoxepin (DDOX) concentrations in serum (or plasma) and red blood cells (RBCs) were measured by radioimmunoassay. Peak serum concentrations of DOX were observed at 1-2 hours and they ranged between 59.1-107.4 nmol/1. DOX disappearance was biphasic with a mean distribution half-life of 2.0 hrs and elimination half-life of 17.9 hrs. The mean total apparent volume of distribution was 22.7 l/kg and plasma clearance 0.93 l/hr/kg. The estimated mean first-pass metabolism of DOX was 71% assuming complete absorption. Peak DDOX concentrations were observed at 1-6 hours and they ranged between 35.0-117.8 nmol/l. DDOX elimination was monophasic with a mean apparent half-life of 28.5 hours. Equilibrium dialysis gave a mean protein binding of 75.5% for DOX and 76.0% for DDOX.

What is Doxepin

Doxepin hydrochloride is a dibenzoxepin-derivative tricyclic antidepressant (TCA). TCAs are structurally similar to phenothiazines. They contain a tricyclic ring system with an alkyl amine substituent on the central ring. In non-depressed individuals, doxepin does not affect mood or arousal, but may cause sedation. In depressed individuals, doxepin exerts a positive effect on mood. TCAs are potent inhibitors of serotonin and norepinephrine reuptake. Tertiary amine TCAs, such as doxepin and amitriptyline, are more potent inhibitors of serotonin reuptake than secondary amine TCAs, such as nortriptyline and desipramine. TCAs also down-regulate cerebral cortical beta;-adrenergic receptors and sensitize post-synaptic serotonergic receptors with chronic use. The antidepressant effects of TCAs are thought to be due to an overall increase in serotonergic neurotransmission. TCAs also block histamine H sub1 /sub receptors, alpha; sub1 /sub-adrenergic receptors and muscarinic receptors, which accounts for their sedative, hypotensive and anticholinergic effects (e.g. blurred vision, dry mouth, constipation, urinary retention), respectively. Doxepin has less sedative and anticholinergic effects than amitriptyline. See toxicity section below for a complete listing of side effects. Doxepin may be used to treat depression and insomnia. Unlabeled indications include chronic and neuropathic pain, and anxiety. Doxepin may also be used as a second line agent to treat idiopathic urticaria.

Doxepin mechanism of action

The mechanism of action of doxepin is not completely understood. It is thought that like amitriptyline, doxepin enhances the actions of norepinephrine and serotonin by blocking their reuptake at the neuronal membrane. However, doxepin weakly inhibits the reuptake of dopamine. Doxepin may also act on histamine H sub1 /sub-receptors, resulting in sedative effects, and beta;-adrenergic receptors. It is also an antagonist of 5-hydroxytryptamine (serotonin) receptors, alpha-1 adrenergic receptor, and muscarinic cholinergic receptors.

Doxepin is used for the treatment of depression and/or anxiety. It can also be used for chronic urticaria and in the management of pain.

Toxicity of Doxepin

LD sub50 /sub=26 (mg/kg) (in mice, iv); LD sub50 /sub=16 (mg/kg) (in rats, iv); Cardiac dysrhythmias, severe hypotension, convulsions, and CNS depression, including coma. Changes in the electrocardiogram, particularly in QRS axis or width, are clinically significant indicators of tricyclic antidepressant toxicity. Side effects include: sedation, hypotension, blurred vision, dry mouth, constipation, urinary retention, postural hypotension, tachycardia, hypertension, ECG changes, heart failure, impaired memory and delirium, and precipitation of hypomanic or manic episodes in bipolar depression. Withdrawal symptoms include gastrointestinal disturbances, anxiety, and insomnia.
