Mode Of Action
Doxylamine Succinate is an antihistamine that blocks Histamine (H1) receptor. It can cross the blood brain barrier and has a high affinity for H1 receptors in the brain that blocks H1 receptors. It also decreases the action of histamine at the H1 receptor by inhibiting both vestibular system & Muscarinic receptor. It affects the vestibular system & decreases the stimulation of the vomiting center. Its muscarinic receptor inhibition may also play a role in antihistamine antiemetic activity. Pyridoxine Hydrochloride is a vitamin B6 analog. It is used to prevent nausea and vomiting due to its antiemetic properties.
Pregnancy
Pregnancy category A. This is intended for the treatment of nausea and vomiting of pregnancy in women who do not respond to conservative management. Both Doxylamine Succinate & Pyridoxine Hydrochloride are excreted into breast milk. Therefore, caution should be exercised while breastfeeding.
