Diphenhydramine Citrate is a medication commonly used for allergies and as a sleep aid. The word is spelled /daɪˌfɛnˈhaɪdrəmiːn ˈsɪtrət/, with the emphasis on the second syllable of "diphenhydramine" and the first syllable of "citrate." The "diphen-" part of the word comes from "diphenyl," meaning a molecule with two phenyl groups attached. "Hydramine" is a combination of "hydra," meaning water, and "amine," a type of organic compound. "Citrate" refers to the salt form of citric acid.
Diphenhydramine citrate is a pharmaceutical compound that is used primarily as an antihistamine medication. It is a combination of two active ingredients, diphenhydramine and citric acid.
Diphenhydramine citrate works by blocking the action of histamine, a chemical released by the body during an allergic reaction. By inhibiting the effects of histamine, it helps to relieve symptoms such as itching, sneezing, runny nose, and watery eyes that are associated with allergies and hay fever. It is also known to produce sedative effects, making it effective in the treatment of insomnia.
The addition of citric acid in diphenhydramine citrate aids in its solubility, making it more readily absorbed by the body when taken orally. This formulation allows for faster onset of action and more rapid relief of symptoms compared to other antihistamine medications.
Diphenhydramine citrate is available in various forms, including tablets, capsules, and oral liquid suspensions. It is usually taken orally, with or without food. The dosage and frequency of administration should be determined by a healthcare professional based on the patient's age, weight, and the severity of their symptoms.
While diphenhydramine citrate is generally considered safe for short-term use, it may cause drowsiness, dizziness, dry mouth, and blurred vision as common side effects. It is important to avoid consuming alcohol or operating machinery while taking this medication due to its sedative properties. As with any medication, it is recommended to consult a healthcare provider before starting diphenhydramine citrate to ensure its appropriateness for the individual's specific medical condition.
The word "diphenhydramine" is derived from the chemical components of the drug. It combines "diphenyl-" which refers to a compound containing two phenyl groups, and "-hydramine" which is related to a class of substances called amines.
The term "citrate" has its roots in the Latin word "citrus", meaning "lemon". Citrate is a salt or ester of citric acid, which is commonly found in citrus fruits.
Therefore, "diphenhydramine citrate" is a combination of these two components, indicating that it is a compound that includes the antihistamine diphenhydramine along with a citrate salt.
