3102 Phenindamine Phenindamine is an antihistamine. Phenindamine blocks the effects of the naturally occurring chemical histamine in your body. Antihistamines such as phenindamine appear to compete with histamine for histamine H1- receptor sites on effector cells. The antihistamines antagonize those pharmacological effects of histamine which are mediated through activation of H1- receptor sites and thereby reduce the intensity of allergic reactions and tissue injury response involving histamine release. It is used to treat sneezing, runny nose, itching, watery eyes, hives, rashes, itching, and other symptoms of allergies and the common cold. Symptoms of a phenindamine overdose include extreme sleepiness, confusion, weakness, ringing in the ears, blurred vision, large pupils, dry mouth, flushing, fever, shaking, insomnia, hallucinations, and possibly seizures. 82-88-2 11291 C19H19N 261.151750 White powder. 91°C 2.77e-02 g/L Antihistamines such as phenindamine appear to compete with histamine for histamine H1- receptor sites on effector cells.
