Medical drugs atropine

THE PATIENT WITH HEART BLOCK. The patient receiving atropine for third-degree heart block is placed on a cardiac monitor during and after administration of the drug. The nurse watches the monitor for a change in pulse rate or rhythm. Tachycardia, other cardiac arrhythmias, or failure of the drug to increase the heart rate must be reported to the primary health care provider immediately because other dm or medical management may be necessary. 

Preanesthetic drugs may be omitted in those 60 years or older because many of the medical disorders for which these drugsare contraindicated are seen in older individuals For example, atropine and glycopyrrolate, drugs that can be used to decrease secretions of the upper respiratory tract, are contraindicated in certain medical disorders such as prostatic hypertrophy, glaucoma, and myocardial ischemia. Other preanesthetic drugs that depress the central nervous astern (CN, such as narcotics barbiturates and antianxiety drugs with or without antiemetic properties may be contraindicated in the older individual.

Surprisingly, it appeared that there had been hardly any therapeutic progress in the management of belladonna poisoning since the 19 century, when opium was the most commonly used treatment. The first six decades of the 20 century spawned many new drugs, but no one seemed to have reported anything good for atropine delirium in mainstream medical journals. 

The oldest drugs of this group are different galena drugs isolated from belladonna (Atropa belladonna), henbane (Hyoscyamus niger), and stramonium (Datura stramonium). They are all obtained from plants that contain the L-hiocyamine and a somewhat lesser qnantity of L-scopolamine. As a mnscarinic receptor blocker, L-hioscyamine is mnch more active that D-hioscyamine on both the periphery as well as on the CNS however, a racemic mixture of D,L-hioscyamine— known better as atropine—is preferred in the majority of medical cases because it is readily available. 

Individuals on very small amounts of heroin are prescribed diazepam for anxiety, agitation or craving, zopiclone or zolpidem for insomnia, hyoscine butylbromide (Buscopan) for stomach cramps, and diphenoxylate/atropine (Lomotil) for diarrhoea, over a seven-day period. The medication schedule provided to the user explains which drug is for which symptoms, and the maximum doses of each that can be taken in a day, which for diazepam varies during the course. The basic medication regime is included in the Appendix. 

The use of atropine became part of routine preoperative medication when anesthetics such as ether were used, because these irritant anesthetics markedly increased airway secretions and were associated with frequent episodes of laryngospasm. Preanesthetic injection of atropine or scopolamine could prevent these hazardous effects. Scopolamine also produces significant amnesia for the events associated with surgery and obstetric delivery, a side effect that was considered desirable. On the other hand, urinary retention and intestinal hypomotility following surgery were often exacerbated by antimuscarinic drugs. Newer inhalational anesthetics are far less irritating to the airways. 

Physostigmine, given intravenously, counteracts both the peripheral and central side effects of atropine and other anticholinergic drugs such as thioridazine (neuroleptic), imipramine (antidepressant), and benztropine (antiparkinsonian medication).
