Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Bystolic (nebivolol) is a beta-1 selective adrenergic receptor antagonist with additional nitric oxide-mediated vasodilatory effects. It decreases heart rate, myocardial contractility, and blood pressure by blocking beta-1 receptors in the heart and kidney, and enhances nitric oxide release from vascular endothelium via beta-3 receptor activation.
Agonist of guanylate cyclase-C (GC-C) receptor on luminal surface of intestinal epithelial cells, increasing cyclic guanosine monophosphate (c GMP) levels, which activates CFTR ion channel, increasing chloride and water secretion into intestinal lumen, accelerating colonic transit and reducing visceral pain.
Hypertension: treatment of hypertension, alone or in combination with other antihypertensives,Heart failure: stable mild to moderate chronic heart failure in addition to standard therapy (off-label)
Irritable bowel syndrome with constipation (IBS-C),Chronic idiopathic constipation (CIC)
Oral: 5 mg once daily; may increase at 2-week intervals to 10 mg, 20 mg, 40 mg; maximum 40 mg/day.
145 mcg orally once daily, at least 30 minutes before the first meal of the day.
Terminal elimination half-life: 10-12 hours; allows once-daily dosing in most patients; steady-state achieved in 3-5 days
Approximately 9–10 hours (terminal half-life in plasma), supporting once-daily dosing.
Extensively metabolized via CYP2D6 and glucuronidation. Active metabolites are formed, including desmethylnebivolol. Genetic polymorphisms in CYP2D6 affect drug levels.
Minimally metabolized; primarily degraded by intestinal peptidases. Not a substrate for CYP450 enzymes.
Renal: 38% unchanged; hepatic metabolism: extensive; fecal: minor; total renal clearance accounts for 30-50% of dose
Primarily fecal as intact peptide (95%); renal excretion of absorbed drug is minimal (<5%).
25-30% bound to albumin (alpha-1-acid glycoprotein not significant)
Approximately 94% bound to plasma proteins (primarily albumin).
Vd: ~2.5 L/kg (extensive extravascular distribution, consistent with moderate lipophilicity)
~5.2 L/kg (large Vd indicating extensive tissue distribution).
Oral: 33% (due to first-pass metabolism; food does not significantly affect AUC; low variability)
Oral: ~0.1% (extremely low due to extensive degradation in GI tract and first-pass metabolism).
No adjustment for mild to moderate renal impairment (Cr Cl ≥30 m L/min). For severe renal impairment (Cr Cl <30 m L/min), initial dose 2.5 mg once daily; titrate cautiously; maximum 20 mg/day.
No dose adjustment required for any degree of renal impairment, including end-stage renal disease on dialysis.
Child-Pugh Class A: initial 2.5 mg once daily; increase cautiously; maximum 20 mg/day. Child-Pugh Class B: initial 2.5 mg once daily; increase cautiously; maximum 10 mg/day. Child-Pugh Class C: not recommended.

No FDA black box warning.
No boxed warning.
Abrupt discontinuation may exacerbate angina or myocardial infarction in coronary artery disease,May mask signs of hyperthyroidism,Caution in peripheral vascular disease and Raynaud's phenomenon,May cause bronchospasm in patients with asthma or COPD,Caution in patients with diabetes mellitus due to masking of hypoglycemia,May cause bradycardia or heart block,Caution in renal or hepatic impairment
Not recommended in pediatric patients; avoid use in patients with known or suspected mechanical gastrointestinal obstruction.,May cause diarrhea, which can be severe; instruct patients to discontinue if severe diarrhea occurs.,Use caution in patients with inflammatory bowel disease (Crohn's, ulcerative colitis) or a history of colonic obstruction.
Sinus bradycardia,Second- or third-degree heart block,Cardiogenic shock,Decompensated heart failure,Sick sinus syndrome (unless pacemaker present),Severe hepatic impairment,Hypersensitivity to nebivolol or any component
Known or suspected mechanical gastrointestinal obstruction.,History of a serious hypersensitivity reaction to linaclotide or any component of the formulation.
Avoid alcohol as it may increase blood pressure-lowering effect. No significant food interactions; however, grapefruit juice may slightly increase nebivolol levels but not clinically relevant.
Food reduces the efficacy of linaclotide; administer at least 30 minutes before a meal. Avoid taking with high-fat meals as they may delay gastric emptying and reduce drug effect. No specific dietary restrictions but maintaining adequate hydration is recommended due to possible diarrhea.
First trimester: Limited human data; animal studies show no teratogenicity at clinically relevant doses. Second/third trimester: Beta-blockers may cause fetal bradycardia, intrauterine growth restriction, and neonatal hypoglycemia; risk is dose-dependent.
Linaclotide is not systemically absorbed after oral administration; animal studies at high oral doses showed no teratogenicity. No human data available; risk to fetus is likely low due to negligible systemic exposure.
Nebivolol is excreted into breast milk; M/P ratio not established. Limited human data; use with caution in nursing mothers due to potential for infant bradycardia and hypotension.
Linaclotide is minimally absorbed systemically; its active metabolite is not measurable in plasma. No data on presence in human milk. M/P ratio unknown; likely low risk due to poor oral bioavailability and large molecular size.
No specific dose adjustments established; use lowest effective dose; increase monitoring for maternal hypotension and fetal bradycardia; consider discontinuation if fetal distress occurs.
No dose adjustment needed; pharmacokinetic changes in pregnancy do not affect systemic exposure due to negligible absorption.
Bystolic (nebivolol) is a beta-1 selective blocker with nitric oxide-mediated vasodilation, resulting in lower incidence of fatigue and sexual dysfunction compared to other beta-blockers. No dose adjustment needed in mild to moderate hepatic impairment but contraindicated in severe impairment. Maximum antihypertensive effect may take 2 weeks. Use caution in patients with asthma or COPD due to beta-1 selectivity may be lost at higher doses. Do not discontinue abruptly; taper over 1-2 weeks.
Linaclotide is a guanylate cyclase-C agonist approved for irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC). Onset of action can occur within 24 hours but maximal effect may take 1-2 weeks. Contraindicated in pediatric patients under 6 years due to risk of severe diarrhea. Avoid use in patients with mechanical gastrointestinal obstruction. Monitor for diarrhea, which may require dose reduction or discontinuation. Capsules should be swallowed whole; do not crush or chew. For patients with difficulty swallowing, capsules may be opened and sprinkled on applesauce or mixed in water for immediate consumption. Renal or hepatic impairment does not require dose adjustment. Linaclotide is not systemically absorbed (active locally).
Take once daily at the same time each day, with or without food.,Do not stop taking suddenly as this may cause chest pain or heart attack; consult your doctor for gradual dose reduction.,May cause dizziness or drowsiness; avoid driving or operating machinery until you know how you react.,Notify your doctor if you experience slow heartbeat, shortness of breath, swelling of feet or legs, or signs of allergic reaction.,Inform all healthcare providers that you take this medication, especially before surgery or any procedure involving anesthesia.
Take linaclotide on an empty stomach, at least 30 minutes before the first meal of the day.,Swallow capsules whole; do not crush, chew, or break.
