Product Description:

Doxepin is a tricyclic antidepressant (TCA) primarily indicated for the treatment of depression, generalized anxiety disorder, chronic insomnia, and certain dermatological conditions such as pruritus. It functions by inhibiting the reuptake of norepinephrine and serotonin, thereby increasing their levels in the central nervous system to improve mood and promote relaxation. The API is supplied as a high-purity, white to off-white crystalline hygroscopic powder, making it suitable for various pharmaceutical dosage forms, including oral capsules, tablets, topical creams, and solutions. Doxepin is valued for its proven clinical efficacy, versatility in formulations, and compatibility with different excipients.
