ics are combined with sedating antihistamines.
Acetaminophen; Dextromethorphan; Guaifenesin; Phenylephrine: Atropine blocks the vagal reflex bradycardia caused by sympathomimetic agents, such as phenylephrine, and increases its pressor effect.
Acetaminophen; Dextromethorphan; Phenylephrine: Atropine blocks the vagal reflex bradycardia caused by sympathomimetic agents, such as phenylephrine, and increases its pressor effect.
Acetaminophen; Dextromethorphan; Pseudoephedrine: Atropine blocks the vagal reflex bradycardia caused by pseudoephedrine, and increases its pressor effect. Patients need to be asked whether they have taken pseudoephedrine before receiving atropine.
Acetaminophen; Diphenhydramine: The anticholinergic effects of sedating H1-blockers may be enhanced when combined with other antimuscarinics. Clinicians should note that anticholinergic effects might be seen not only on GI smooth muscle, but also on bladder function, the eye, and temperature regulation. Additive drowsiness may also occur when antimuscarinics are combined with sedating antihistamines.
Acetaminophen; Guaifenesin; Phenylephrine: Atropine blocks the vagal reflex bradycardia caused by sympathomimetic agents, such as phenylephrine, and increases its pressor effect.
Acetaminophen; Hydrocodone: Concurrent use of antidiarrheals and hydrocodone can lead to severe constipation and possibly additive CNS depression. Opiate analgesics combined with antimuscarinics can cause severe constipation or paralytic ileus, especially with chronic use.
Acetaminophen; Oxycodone: Opiate agonists should be used cautiously with antimuscarinics since additive depressive effects on GI motility or bladder function may been seen. Opioids increase the tone and decrease the propulsive contractions of the smooth muscle of the gastrointestinal tract. Prolongation of the gastrointestinal transit time may be the mechanism of the constipating effect. Opiate analgesics combined with antimuscarinics can cause severe constipation or paralytic ileus, especially with chronic use. Pharmacology texts report that meperidine exerts less pronounced effects on GI smooth muscle than other opiate agonists.
Acetaminophen; Pentazocine: Use pentazocine with caution in any patient receiving anticholinergic agents. Coadministration of pentazocine with antimuscarinics may result in additive anticholinergic effects, such as urinary retention and constipation.
Acetaminophen; Pseudoephedrine: Atropine blocks the vagal reflex bradycardia caused by pseudoephedrine, and increases its pressor effect. Patients need to be asked whether they have taken pseudoephedrine before receiving atropine.
Aclidinium: Although aclidinium is minimally absorbed into the systemic circulation after inhalation, there is the potential for aclidinium to have additive anticholinergic effects when administered with other anticholinergics or antimuscarinics.Per the manufaturer, avoid concomitant administration of aclidinium with other anticholinergic medications, when possible.
Acrivastine; Pseudoephedrine: Atropine blocks the vagal reflex bradycardia caused by pseudoephedrine, and increases its pressor effect. Patients need to be asked whether they have taken pseudoephedrine before receiving atropine. The anticholinergic effects of sedating H1-blockers may be enhanced when combined with other antimuscarinics. Clinicians should note th |
