Description

The anticholinergics/antispasmodicsare a group of medicines that include the natural belladonna alkaloids (atropine,belladonna, hyoscyamine, and scopolamine) and related products.

The anticholinergics/antispasmodics are used to relieve cramps or spasmsof the stomach, intestines, and bladder. Some are used together with antacidsor other medicine in the treatment of peptic ulcer. Others are used to preventnausea, vomiting, and motion sickness.

Anticholinergics/antispasmodics are also used in certain surgical and emergencyprocedures. In surgery, some are given by injection before anesthesia to helprelax you and to decrease secretions, such as saliva. During anesthesia andsurgery, atropine, glycopyrrolate, hyoscyamine, and scopolamine are used tohelp keep the heartbeat normal. Scopolamine is also used to preventnausea and vomiting after anesthesia and surgery. Atropine is also given byinjection to help relax the stomach and intestines for certain types of examinations.Some anticholinergics are also used to treat poisoning caused by medicinessuch as neostigmine and physostigmine, certain types of mushrooms, and poisoningby ?nerve?' gases or organic phosphorous pesticides (for example,demeton [Systox], diazinon, malathion, parathion, and ronnel [Trolene]). Also,anticholinergics can be used for painful menstruation, runny nose, and toprevent urination during sleep.

These medicines may also be used for other conditions as determined byyour doctor.

Before Using This Medicine

In deciding to use a medicine,the risks of taking the medicine must be weighed against the good it willdo. This is a decision you and your doctor will make. For anticholinergics/antispasmodicsthe following should be considered:

Allergies?Tell your doctor if you have ever had any unusual orallergic reaction to any of the natural belladonna alkaloids (atropine, belladonna,hyoscyamine, and scopolamine), or any related products. Also, tell your healthcare professional if you are allergic to any other substances, such as foods,preservatives, or dyes.

Pregnancy?If you are pregnant or if you may become pregnant,make sure your doctor knows if your medicine contains any of the following:

  • Atropine?Atropine has not been shownto cause birth defects or other problems in animals. However, when injectedinto humans during pregnancy, atropine has been reported to increase the heartbeatof the fetus.
  • Belladonna?Studies on effects inpregnancy have not been done in either humans or animals.
  • Clidinium?Clidinium has not beenstudied in pregnant women. However, clidinium has not been shown to causebirth defects or other problems in animal studies.
  • Dicyclomine?Dicyclomine has beenassociated with a few cases of human birth defects but dicyclomine has notbeen confirmed as the cause.
  • Glycopyrrolate?Glycopyrrolate hasnot been studied in pregnant women. However, glycopyrrolate did not causebirth defects in animal studies, but did decrease the chance of becoming pregnantand the newborn's chance of surviving after weaning.
  • Hyoscyamine?Studies on effects inpregnancy have not been done in either humans or animals. However, when injectedinto humans during pregnancy, hyoscyamine has been reported to increase theheartbeat of the fetus.
  • Mepenzolate?Mepenzolate has notbeen studied in pregnant women. However, studies in animals have not shownthat mepenzolate causes birth defects or other problems.
  • Propantheline?Studies on effectsin pregnancy have not been done in either humans or animals.
  • Scopolamine?Studies on effects inpregnancy have not been done in either humans or animals.

Breast-feeding?Although these medicines may pass into the breastmilk, they have not been reported to cause problems in nursing babies. However,the flow of breast milk may be reduced in some patients. The use of dicyclominein nursing mothers has been reported to cause breathing problems in infants.

Children?Unusual excitement, nervousness, restlessness, orirritability and unusual warmth, dryness, and flushing of skin are more likelyto occur in children, who are usually more sensitive to the effects of anticholinergics.Also, when anticholinergics are given to children during hot weather, a rapidincrease in body temperature may occur. In infants and children, especiallythose with spastic paralysis or brain damage, this medicine may be more likelyto cause severe side effects. Shortness of breath or difficulty in breathinghas occurred in children taking dicyclomine.

Older adults?Confusion or memory loss; constipation; difficulturination; drowsiness; dryness of mouth, nose, throat, or skin; and unusualexcitement, nervousness, restlessness, or irritability may be more likelyto occur in the elderly, who are usually more sensitive than younger adultsto the effects of anticholinergics. Also, eye pain may occur, which may bea sign of glaucoma.

Other medicines?Although certain medicines should not be usedtogether at all, in other cases two different medicines may be used togethereven if an interaction might occur. In these cases, your doctor may want tochange the dose, or other precautions may be necessary. When you are takinganticholinergics/antispasmodics, it is especially important that your healthcare professional know if you are taking any of the following:

  • Antacids or
  • Diarrhea medicine containing kaolin or attapulgite or
  • Ketoconazole (e.g., Nizoral)?Using these medicines with ananticholinergic may lessen the effects of the anticholinergic
  • Central nervous system (CNS) depressants (medicines that cause drowsiness)?Takingscopolamine with CNS depressants may increase the effects of either medicine
  • Other anticholinergics (medicine for abdominal or stomach spasmsor cramps) or
  • Tricyclic antidepressants (amitriptyline [e.g., Elavil], amoxapine[e.g., Asendin], clomipramine [e.g., Anafranil], desipramine [e.g., Pertofrane],doxepin [e.g., Sinequan], imipramine [e.g., Tofranil], nortriptyline [e.g.,Aventyl], protriptyline [e.g., Vivactil], trimipramine [e.g., Surmontil])?Takinganticholinergics with tricyclic antidepressants or other anticholinergicsmay cause an increase in the effects of the anticholinergic
  • Potassium chloride (e.g., Kay Ciel)?Using this medicine withan anticholinergic may make gastrointestinal problems caused by potassiumworse

Other medical problems?The presence of other medicalproblems may affect the use of anticholinergics/antispasmodics. Make sureyou tell your doctor if you have any other medical problems, especially:

  • Bleeding problems (severe)?These medicines may increase heartrate, which would make bleeding problems worse
  • Brain damage (in children)?May increase the CNS effects ofthis medicine
  • Colitis (severe) or
  • Dryness of mouth (severe and continuing) or
  • Enlarged prostate or
  • Fever or
  • Glaucoma or
  • Heart disease or
  • Hernia (hiatal) or
  • High blood pressure (hypertension) or
  • Intestinal blockage or other intestinal problems or
  • Lung disease (chronic) or
  • Myasthenia gravis or
  • Toxemia of pregnancy or
  • Urinary tract blockage or difficult urination?These medicinesmay make these conditions worse
  • Down's syndrome?These medicines may cause an increase in pupildilation and heart rate
  • Kidney disease or
  • Liver disease?Higher blood levels may occur and cause an increasein side effects
  • Overactive thyroid?These medicines may further increase heartrate
  • Spastic paralysis (in children)?This condition may increasethe effects of the anticholinergic
