| Mechanism of Action | Doxepin HCl is a tricyclic antidepressant that increases the concentration of serotonin (5-HT) and norepinephrine (NE) in the brain by inhibiting their reuptake into the presynaptic terminal. It also acts as an antagonist at histamine (H1), α1 adrenergic, and muscarinic receptors, which contributes to its sedative and antipruritic effects. |
| Resistance and Combination Therapy | Resistance to doxepin can occur due to genetic variations in drug metabolism (e.g., CYP2D6 polymorphisms) or due to long-term use leading to receptor desensitization. Combination therapy with other agents, such as benzodiazepines for insomnia or NSAIDs for pain management, may be used to enhance efficacy. |
| Storage Conditions | Doxepin HCl capsules and oral concentrate should be protected from direct sunlight and stored in well-closed, light-resistant containers at a temperature between 15°C and 30°C |
