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.
Treprostinil is a synthetic prostacyclin analog that directly vasodilates pulmonary and systemic arterial beds, inhibits platelet aggregation, and suppresses smooth muscle proliferation.
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)
Pulmonary arterial hypertension (WHO Group I) to improve exercise capacity and reduce symptoms,Off-label: Severe Raynaud's phenomenon, digital ischemia, and salvage therapy for PAH in patients failing other prostacyclins
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.
Continuous subcutaneous infusion: Initially 1.25 ng/kg/min; increase by 1.25 ng/kg/min every week for first 4 weeks, then by 2.5 ng/kg/min every week as tolerated. Intravenous infusion: same dosing.
Terminal half-life is approximately 1-4 minutes for nitroglycerin; clinical effect duration is longer due to tissue distribution.
Terminal elimination half-life is approximately 4 hours (range 2-7 hours) following continuous subcutaneous infusion; clinical context: requires continuous infusion due to short half-life.
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.
Hepatic metabolism via CYP2C8 and CYP2C9 (major), with minor contributions from CYP2C19 and CYP2D6; major metabolite is a glucuronide conjugate.
Primarily renal excretion of inactive metabolites; less than 1% excreted unchanged. Biliary/fecal elimination is minimal.
Renal: 20-30% as unchanged drug; fecal: 70-80% as metabolites (via biliary elimination).
Approximately 60% bound to plasma proteins (albumin).
Approximately 58% bound to human plasma proteins, primarily to albumin.
Vd is about 3 L/kg, indicating extensive tissue distribution.
Volume of distribution (Vd) is 1.3 L/kg (range 0.8-2.0 L/kg); clinical meaning: extensive distribution into tissues, exceeding total body water.
Transdermal: approximately 70-80% of the dose reaches systemic circulation.
Subcutaneous: approximately 100% bioavailable compared to intravenous; oral: negligible (not administered orally).
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.
No dosage adjustment required for renal impairment.
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.
Mild to moderate hepatic impairment (Child-Pugh class A or B): no adjustment. Severe hepatic impairment (Child-Pugh class C): contraindicated.
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.
Not established; safety and efficacy in pediatric patients have not been studied.
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 specific dose adjustment recommended; use with caution due to age-related renal/hepatic decline.
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.
None. However, infusion site reactions (pain, erythema, induration) and risk of catheter-related bloodstream infections are significant concerns.
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.
Sudden discontinuation may worsen PAH; taper if possible.,Infusion site reactions are common; avoid extravasation.,Risk of bleeding due to antiplatelet effects; use with caution in patients with peptic ulcer disease or on anticoagulants.,Hepatic impairment may increase exposure; dosage adjustment may be needed.,May cause systemic hypotension; monitor blood pressure.
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.
Known hypersensitivity to treprostinil or any excipient,Patients with severe hepatic impairment (Child-Pugh class C) due to lack of safety data
Concurrent use of alcohol can cause vasodilation and hypotension. Limit or avoid alcohol. No specific food restrictions.
There are no known food interactions with treprostinil. However, patients should maintain a balanced diet as part of overall PAH management. Grapefruit juice has not been reported to interact, but always consult with a healthcare provider.
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.
Teriprostinil (REMODULIN) is contraindicated in pregnancy due to teratogenic effects in animal studies (increased cardiovascular and skeletal malformations). There are no adequate human data; however, based on animal findings, fetal risk cannot be excluded, particularly in the first trimester. In later trimesters, risks include potential fetal harm from maternal hypotension and hypoxia.
Likely excreted in breast milk. M/P ratio not established. Use with caution; monitor infant for hypotension.
It is unknown if teriprostinil is excreted in human milk. M/P ratio not established. Due to potential for serious adverse reactions in nursing infants, breastfeeding is not recommended during treatment and for at least 48 hours after the last dose.
No specific dose adjustments recommended, but use lowest effective dose due to potential for hypotension and decreased placental perfusion.
Pregnancy is a contraindication; thus no dose adjustments are applicable. However, if used in exceptional circumstances, plasma volume expansion in pregnancy may alter drug distribution, but specific dose recommendations are lacking. Use is not recommended.
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.
REMODULIN (treprostinil) is a prostacyclin analog used for pulmonary arterial hypertension (PAH). Avoid abrupt discontinuation due to risk of rebound pulmonary hypertension. Monitor for infusion site reactions and bleeding risk due to antiplatelet effects. Dose titration should be guided by PAH symptoms and side effects. Use with caution in patients with hepatic impairment.
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.
Do not stop taking this medication suddenly; sudden cessation may cause worsening of symptoms.,Report any signs of bleeding (e.g., easy bruising, nosebleeds, blood in urine or stool) to your healthcare provider.,If using subcutaneous infusion, rotate injection sites to prevent site reactions and infection.,Store medication as directed; do not freeze or expose to excessive heat.,Avoid activities that increase bleeding risk, such as contact sports, until you discuss with your doctor.
