Diphenhydraz in ampoules refers to the pharmacological group of drugs used to treat types of allergies, as well as sedatives and hypnotics. After intravenous, intramuscular administration, the drug quickly spreads through the body, passes through the blood-brain barrier and the placenta. The active substance of the drug is associated with plasma proteins at 98-99%. The active substance breaks down in the liver. The half-life (T1 / 2) of the drug is 1-4 hours. During the day, it is completely eliminated from the body mainly in the form of benzhydrol conjugated with glucuronic acid, and only in an insignificant amount - unchanged.
Dimedrol interaction with other drugs
Features of the interaction of the drug with other drugs and substances are as follows:
Diphenhydramine in ampoules enhances the effect of drugs that suppress the central nervous system. Therefore, the drug must be carefully taken with sleeping pills, neuroleptics, narcotic analgesics.
Dimedrol injection solution enhances the effect of anticholinergics and slows the motility of the digestive tract, which reduces the absorption (absorption) of drugs. If you take diphenhydramine simultaneously with indirect anticoagulants or paracetamol, the effectiveness of the latter will be significantly reduced.
When interacting with alcohol, Dimedrol increases its toxicity.
When is prescribed diphenhydramine (Dimedrol)?
The functional potential of the drug is quite extensive. It is used as an antihistamine, antiallergic, antiemetic, hypnotic, local anesthetic. In case of allergy, Dimedrol blocks histamine H1 receptors, thereby reducing the activity of histamine. As a result, the allergic reaction becomes less pronounced: spasms of the smooth muscles (the surface of the internal organs is covered with it) are stopped, and the capillary permeability increases. It also eliminates swelling of the tissues, itching and hyperemia (redness).
