Benadryl diphenhydramine, benaprizine benapryzine. benapryzine [ban] (benaprizine [inn] benapryzine hydrochloride [usan]) is a benzilate, a muscarinic CHOLINOCEPTOR ANTAGONIST which has been used as an ANTIPARKINSONIAN AGENT. 

The prototype of the antihistamines based on benzhydrol, diphenhydramine (3), is familiar to many today under the trade name Benadryl . Light-induced bromination of diphenylmethane affords benzhydryl bromide (2). This is then allowed to react with dimethylaminoethanol to give the desired ether. Although no mechanistic studies have been reported, it is not unlikely that I he bromine undergoes SNi solvolysis in the reaction medium the carbonitjm ion then simply picks up the alcohol. It might be noted in passing that the theophyline salt of 4 is familiar to many Iravelers as a motion sickness remedy under the trade name Oram amine . 

Administration of atropine with meperidine (Demerol), flurazepam (Dalmane), diphenhydramine (Benadryl), phenothiazines, and the tricyclic antidepressants may increase the effects of atropine. There is a decreased effectiveness of haloperidol when administered with the anticholinergic dragp. 

Antihistamines are drags used to counteract the effects of histamine on body organs and structures. Examples of antihistamines include diphenhydramine (Benadryl), loratadine (Claritin), fexofenadine (Allegra), and cetirizine (Zyrtec). A new antihistamine, deslorata-dine (Clarinex), is die active metabolite of loratadine and is intended to eventually replace loratadine (Claritin). Topical corticosteroid nasal sprays such as fluticasone propionate (Flonase) or triamcinolone ace-tonide (Nasacort AQ) are also used for nasal allergy symptoms. See Chapter 56 for more information on die topical corticosteroids.

Antihistamines. After alcohol, antihistamines are the most commonly self-administered sleep medications. Foremost among these is diphenhydramine (Benadryl), which is also available as a component in a variety of over-the-counter nighttime medications including Tylenol PM and Excedrin PM. Prescription antihistamines like hydroxyzine (Vistaril, Atarax) are also occasionally used to treat insomnia. Finally, it is the antihistamine effect of some antidepressants and anti-psychotics that contribute to their utility as sedative-hypnotics. 

Take a Second Medication as a Countermeasure. Sometimes despite problematic side effects, it may be necessary that a patient remain on a particular medication. This is a good time to address the risk-benefit approach to side effects. The best comparison is not the side effects associated with a particular medication compared to the lack of side effects without taking the pill it is the side effects of treatment versus the consequences of the untreated disease state. So what if a patient is on a medication that works for them when previous trials have proved unsuccessful, but there is the presence of one or more uncomfortable side effects This does not necessarily leave you powerless to deal with the side effects. One approach is to use a second medication to counteract the side effect of the first medication. One common example of this approach is using anticholinergic medications such as diphenhydramine (Benadryl) or benztropine (Cogentin) to counteract certain side...
