Zendryl Syrup is a combination medicine containing diphenhydramine, ammonium chloride, and sodium citrate which helps in reducing cough with phlegm.
Diphenhydramine blocks the effects of allergic chemicals and provides relief from allergic symptoms such as running nose and watery eyes.
Ammonium chloride is an expectorant agent which increases the water content in the windpipe. Therefore, cough associated with thick mucus (phlegm) is relieved by making the mucus easy to expel.
Sodium citrate is a mucolytic agent which decreases the consistency of this mucus and makes it thin. Thus, these agents help to remove this mucus from the windpipe and lungs and improve the patient’s condition.
Oral bioavailability of diphenhydramine is in the range of 40% to 60%, and peak plasma concentration occurs about 2 to 3 hours after administration. The primary route of metabolism is two successive demethylations of the tertiary amine.
Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
