Diphenhydramine
Diphenhydramine is a histamine H1 antagonist used as an antiemetic, antitussive, for dermatoses and pruritus, for hypersensitivity reactions, as a hypnotic, an antiparkinson, and as an ingredient in common cold preparations. It has some undesired antimuscarinic and sedative effects. -- Pubchem; Pseudoephedrine is a phenethylamine, and an isomer of ephedrine. Pseudoephedrine is the International Nonproprietary Name (INN) of the (1S,2S)- diastereomer of ephedrine (which has 1R,2S- configuration). Other names are (+)-pseudoephedrine and D-pseudoephedrine (Reynolds, 1989). The enantiomer (-)-(1R,2R)-Pseudoephedrine has fewer side-effects, fewer central nervous system (CNS) stimulatory effects, does not reduce to d-methamphetamine, yet retains its efficacy as a decongestant.[citation needed] However, the patent holder for (-)-Pseudoephedrine (Pfizer/Warner-Lambert) has not yet sought or received government approval for its sale to the public.(US Patent 6,495,529); Treatment for urinary incontinence is an unlabeled use for these medications. Unlabeled use means doctors can use the medication to treat a condition other than that for which it was first approved by the U.S. Food and Drug Administration (FDA). These medications are approved by the FDA for the treatment of nasal congestion caused by colds or allergies. However it has also been successful in treating stress incontinence by increasing the pressure (tension) exerted by the muscles of the bladder neck and the urethra, which helps retain the urine within the bladder. Despite being one of the oldest antihistamines on the market, it is by and large the most effective antihistamine available, either by prescription or over-the-counter, and has been shown to exceed the effectiveness of even the latest prescription drugs. Consequently, it is frequently used when an allergic reaction requires fast, effective reversal of the (often dangerous) effects of a massive histamine release. However, it is not always the drug of choice for treating allergies. Like many other first generation antihistamines, is also a potent anticholinergic agent. This leads to profound drowsiness as a very common side-effect, along with the possibilities of motor impairment (ataxia), dry mouth and throat, flushed skin, rapid or irregular heartbeat (tachycardia), blurred vision at near point due to lack of accommodation (cycloplegia), abnormal sensitivity to bright light (photophobia), pupil dilatation, urinary retention, constipation, difficulty concentrating, short-term memory loss, visual disturbances, hallucinations, confusion, erectile dysfunction, and delirium. -- Wikipedia;.

Tripelennamine
Tripelennamine is only found in individuals that have used or taken this drug. It is a histamine H1 antagonist with low sedative action but frequent gastrointestinal irritation. It is used to treat asthma; HAY fever; urticaria; and rhinitis; and also in veterinary applications. Tripelennamine is administered by various routes, including topically. [PubChem]Tripelennamine binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.

N-Demethyl orphenadrine
N-Demethyl orphenadrine is a metabolite of orphenadrine. Orphenadrine is an anticholinergic drug of the ethanolamine antihistamine class with prominent CNS and peripheral actions used to treat painful muscle spasms, other similar conditions, as well as the treatment of some aspects of Parkinsons Disease. It is closely related to diphenhydramine. Therefore, it is related to other drugs used for Parkinsons like benztropine and trihexyphenidyl, and it is also structurally related to nefopam, which is a centrally-acting yet non-opioid analgesic.
