5-HT3 Antagonists
ADRs include HA, dizziness, diarrhea, abdominal pain
5-HT3 Antagonists
This class can antagonize D2 and (at high enough doses) 5-HT3 receptors. Also promote gastric emptying and peristalsis of SI
Dopamine Antagonist
Contraindications include GI hemorrhage, obstruction, or perforation, pheochromocytoma, seizure. Use cautiously in children and depression
Dopamine antagonist
ADRs include extrapyramidial effects, restlessness, anxiety, drowsiness, fatigue, hallucinations, HTN, HPOTN, AV block, bradycardia, agranulocytosis
Dopamine antagonist
This class blocks H1 and is an antagonist of D2 receptors in the CTZ
Antihistamines
ADRs include dry mouth, dizziness, Parkinsonian symptoms, neuroleptic malignant syndrome, blood dyscrasias
Antihistamines
Caution in patients with BPH, urinary retention, glaucoma
Antihistamines
Side effects include drowsiness, sedation, increased appetite
Dronabinol (Cannabinoids)
Medications that cause constipation
OPIATES Ca and Al antacids Calcium channel blockers Clonidine Anticholinergics
These drugs increase the volume of non-absorbable solid residue with water and stimulate peristaltic activity increasing the rate of colonic transit
Bulk forming laxatives
adequate fluid intake is very important with these agents
Bulk forming laxatives
1st line for bedridden or geriatric pt with chronic constipation. Good in pregnancy
Bulk forming laxatives
ADRs include flatulence, abdominal distention, GI obstruction
