Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Vertavis is an inhibitor of acetylcholinesterase, increasing acetylcholine levels at cholinergic synapses.
Nitroglycerin is converted to nitric oxide (NO) in vascular smooth muscle, which activates guanylyl cyclase, increasing c GMP levels. This leads to dephosphorylation of myosin light chains and vasodilation, particularly in venous capacitance vessels and coronary arteries, reducing preload and afterload.
Treatment of mild to moderate Alzheimer's disease,Off-label: treatment of other dementias, myasthenia gravis
Acute angina pectoris,Prophylaxis of angina pectoris (prior to activities that may provoke an attack),Chronic angina (off-label: long-term prophylaxis),Heart failure associated with acute myocardial infarction (off-label)
5 mg orally three times daily. May be increased to 10 mg three times daily if tolerated.
Minitran (nitroglycerin transdermal) is applied as a transdermal patch. Initial dose: 0.2-0.4 mg/hour applied once daily. Titrate based on response and tolerance. Maximum dose: 0.8 mg/hour. The patch is worn for 12-14 hours daily with a 10-12 hour nitrate-free interval to prevent tolerance.
Terminal elimination half-life is 39–58 hours (mean 49 hours), supporting once-daily dosing. Steady state is achieved after 7–10 days.
Terminal half-life is approximately 1-4 minutes for nitroglycerin; clinical effect duration is longer due to tissue distribution.
Primarily hydrolyzed by plasma esterases; minor hepatic metabolism via CYP450 enzymes.
Rapidly metabolized in the liver by glutathione-organic nitrate reductase, with minor contributions from vascular wall and RBC metabolism. Metabolites include 1,2-glyceryl dinitrate and 1,3-glyceryl dinitrate.
Approximately 70% of the dose is excreted renally as unchanged drug and 30% via biliary/fecal routes as metabolites.
Primarily renal excretion of inactive metabolites; less than 1% excreted unchanged. Biliary/fecal elimination is minimal.
Approximately 99% bound to plasma proteins, primarily albumin and alpha-1-acid glycoprotein.
Approximately 60% bound to plasma proteins (albumin).
Volume of distribution is 0.4–0.6 L/kg (approx 30–50 L in adults), indicating distribution primarily into extracellular fluid.
Vd is about 3 L/kg, indicating extensive tissue distribution.
Oral bioavailability is approximately 50% (range 30–70%) with food reducing rate but not extent of absorption.
Transdermal: approximately 70-80% of the dose reaches systemic circulation.
No dose adjustment required for mild to moderate renal impairment. For severe renal impairment (e GFR <30 m L/min/1.73 m²), use is not recommended.
No specific dose adjustment required for renal impairment. However, patients with severe renal insufficiency (Cr Cl <30 m L/min) may have increased risk of adverse effects; monitor closely.
Not recommended for use in patients with moderate to severe hepatic impairment (Child-Pugh class B or C). No data available.
No specific dose adjustment recommended for Child-Pugh A or B. For Child-Pugh C (severe hepatic impairment), consider reducing dose due to reduced metabolism and increased risk of hypotension; use with caution.
Safety and efficacy not established; no recommended dose.
Safety and effectiveness in pediatric patients have not been established. Use only under expert guidance. Typical initial dose: 0.1-0.2 mg/hour transdermally, titrated cautiously based on clinical response and tolerance.
No specific dose adjustment; use with caution due to potential increased sensitivity and comorbidities.
Elderly patients may be more sensitive to the hypotensive effects. Start at the lower end of dosing range (0.2 mg/hour) and titrate slowly. Monitor blood pressure and heart rate regularly.
No FDA black box warning.
Do not use MINITRAN in patients taking phosphodiesterase-5 inhibitors (e.g., sildenafil, tadalafil, vardenafil) as this can cause severe hypotension. Additionally, MINITRAN should not be used in patients with early myocardial infarction or severe anemia.
Cardiovascular effects (bradycardia, syncope),Gastrointestinal effects (nausea, vomiting, diarrhea),Seizures,Weight loss
Hypotension; paradoxical bradycardia; tolerance (need for nitrate-free interval); exacerbation of angina with abrupt discontinuation; use with caution in patients with volume depletion, hypotension, or hypertrophic cardiomyopathy.
Hypersensitivity to Vertavis or any component,History of severe cholinergic adverse effects
Concurrent use of phosphodiesterase-5 inhibitors (e.g., sildenafil, tadalafil, vardenafil); severe anemia; increased intracranial pressure (e.g., head trauma, cerebral hemorrhage); acute circulatory failure; hypersensitivity to nitrates.
Avoid grapefruit and grapefruit juice as they may increase ergotamine levels and risk of toxicity. Limit caffeine intake as it can exacerbate headache and interact with ergotamine. Avoid tyramine-rich foods (aged cheese, cured meats, fermented products) if migraines are triggered by tyramine.
Concurrent use of alcohol can cause vasodilation and hypotension. Limit or avoid alcohol. No specific food restrictions.
Contraindicated in pregnancy. FDA Pregnancy Category X. In animals, ribociclib (active ingredient) caused embryotoxicity, fetotoxicity, and teratogenicity at maternal exposures below human clinical exposure at 400 mg/day. First trimester: high risk of major congenital malformations; second and third trimesters: risk of fetal growth restriction and fetal death.
Category C. Animal studies show fetal harm; no adequate human studies. Use only if maternal benefit outweighs risk. First trimester: possible teratogenic effects. Second/third trimesters: risk of fetal bradycardia, hypotension, and decreased placental perfusion.
Contraindicated during breastfeeding. No data on presence in human milk; however, animal studies show drug and metabolites are excreted in milk. M/P ratio not known. Due to potential for serious adverse reactions in breastfed infants, advise women not to breastfeed during treatment and for at least 3 weeks after last dose.
Likely excreted in breast milk. M/P ratio not established. Use with caution; monitor infant for hypotension.
No dose adjustments recommended during pregnancy as the drug is contraindicated. If unintentionally exposed, discontinue immediately. Physiologic changes in pregnancy may alter drug pharmacokinetics (e.g., increased volume of distribution, increased hepatic clearance), but no specific dose adjustment has been studied in pregnant women.
No specific dose adjustments recommended, but use lowest effective dose due to potential for hypotension and decreased placental perfusion.
Vertavis (a combination of phenobarbital, ergotamine, and belladonna alkaloids) is used for migraine and tension-type headaches. Monitor for signs of ergotism (numbness, cold extremities, muscle pain) due to ergotamine; avoid prolonged use. Phenobarbital is a controlled substance (C-IV) with abuse potential; monitor for sedation and dependence. Belladonna alkaloids cause anticholinergic effects (dry mouth, blurred vision, urinary retention). Taper dose to avoid withdrawal; avoid in patients with peripheral vascular disease, coronary artery disease, or glaucoma.
MINITRAN (nitroglycerin transdermal) is used for angina prophylaxis, not acute attacks. Apply to hairless area, rotate sites, and remove for 12-14 hours daily to prevent tolerance. If headache occurs, reduce dose or use acetaminophen. Do not discontinue abruptly to avoid rebound ischemia.
Take Vertavis at the first sign of headache; do not exceed recommended dose.,Do not use more than 10 days per month to avoid medication-overuse headache and ergotamine toxicity.,Report symptoms of ergotism such as cold fingers or toes, numbness, tingling, or muscle pain immediately.,This medication may cause drowsiness or dizziness; avoid driving or operating machinery until you know how you react.,Avoid alcohol; it can increase sedation and ergotamine side effects.,Do not suddenly stop taking this medication; withdrawal may cause rebound headaches or seizures.
Apply patch to clean, dry, hairless skin on chest, arm, or back; rotate sites daily.,Remove patch after 12-14 hours to prevent tolerance; apply new patch at same time next morning.,Do not use for acute angina; use sublingual nitroglycerin instead.,Avoid alcohol and erectile dysfunction drugs like sildenafil; can cause severe hypotension.,Headache may occur; use acetaminophen or reduce dose; do not stop abruptly.
