商品名：Sinequan
Tricyclic antidepressant (TCA). For treatment of depression, this class of drugs is thought to act by increasing synaptic concentrations of norepinephrine and serotonin (5-HT) in the CNS. Doxepin is only a moderate to weak inhibitor of the reuptake of these neurotransmitters. Doxepin also has antihistamine (H1) properties.
Doxepin has been used to treat anxiety disorders and dermatologic conditions in dogs and cats. Some use for dermatitis is related to the drug’s antihistamine properties. Although it has been used for treating pruritus and dermatitis in small animals, it has not been effective for treating atopic dermatitis in dogs. Doxepin has been used to treat lick granuloma in dogs.
