Generic Monoket Information

Introduction

Monoket is a nitrate‑based medication whose active ingredient is Isosorbide Mononitrate. It is primarily prescribed to prevent episodes of chest pain (angina) caused by reduced blood flow to the heart. In Hong Kong, Isosorbide Mononitrate is listed in the Hospital Authority formulary for chronic stable angina and is available through licensed pharmacies. Although some product databases erroneously categorize the drug under “Anti‑Viral,” its therapeutic class is long‑acting nitrate and it does not possess antiviral activity. The medication is manufactured by several global pharmaceutical companies and marketed under various brand names, the most widely recognized being Imdur. Monoket offers the same active compound in a convenient oral tablet form.

What is Monoket?

Monoket is an oral tablet that contains the single active pharmaceutical ingredient (API) Isosorbide Mononitrate. It belongs to the pharmacological group of long‑acting nitrates and is used as a prophylactic agent for angina pectoris. The drug was developed in the 197s as a mononitrate derivative of isosorbide dinitrate, providing a more predictable pharmacokinetic profile and once‑daily dosing. Several manufacturers produce Monoket under license; the tablets are typically film‑coated and supplied in strengths of 20 mg, 40 mg, and 60 mg.

Monoket is the generic version of the well‑known brand Imdur, containing the same active compound Isosorbide Mononitrate. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Monoket Works

Isosorbide Mononitrate releases nitrate ions after oral absorption. These ions are converted in vascular smooth‑muscle cells to nitric oxide (NO), a potent endogenous vasodilator. NO activates guanylate cyclase, raising intracellular cyclic guanosine monophosphate (cGMP). Elevated cGMP leads to relaxation of smooth muscle in veins and, to a lesser extent, arteries. The primary therapeutic effect is venous dilation, which reduces venous return (preload) to the heart. Lower preload decreases myocardial wall tension and oxygen demand, thereby preventing angina episodes.

Key pharmacokinetic points:

• Onset of action: 30–60 minutes after ingestion.
• Peak plasma concentration: 2–4 hours.
• Duration of effect: 12–24 hours, supporting once‑daily dosing.
• Elimination: Predominantly renal, with a half‑life of approximately 5 hours for the active metabolite.

Because the drug’s effect is sustained, it provides stable hemodynamic control without the tachyphylaxis (tolerance) seen with short‑acting nitrates.

Conditions Treated with Monoket

• Chronic stable angina pectoris – Monoket reduces the frequency and severity of exertional chest pain by lowering myocardial oxygen consumption.
• Secondary prevention in coronary artery disease – When combined with other anti‑ischemic agents (β‑blockers, calcium‑channel blockers), it contributes to overall symptom control.

In Hong Kong, cardiovascular disease accounts for more than 30 % of all deaths, and angina is a common presentation in adult cardiology clinics. Long‑acting nitrates like Monoket are integral to guideline‑directed medical therapy (GDMT) for these patients, especially when lifestyle modification and first‑line agents are insufficient.

Who is Monoket For?

Monoket is appropriate for adult patients (≥ 18 years) with a confirmed diagnosis of chronic stable angina who require ongoing prophylaxis. It is especially useful when:

• Symptoms persist despite optimal β‑blocker therapy.
• Combination therapy with calcium‑channel blockers is planned, and a nitrate is needed for additive vasodilatory effect.
• Patients prefer a once‑daily regimen, improving adherence over short‑acting nitrate preparations.

Contra‑indications and situations where Monoket should be avoided include:

• Known hypersensitivity to isosorbide mononitrate or any nitrate.
• Severe hypotension (systolic blood pressure < 90 mmHg).
• Recent use of phosphodiesterase‑5 inhibitors (e.g., sildenafil) due to risk of profound vasodilation.
• Unstable angina, acute myocardial infarction, or severe aortic stenosis where rapid hemodynamic changes are unsafe.

Clinicians must evaluate renal function before initiating therapy, as impaired clearance can increase systemic exposure.

Risks, Side Effects, and Interactions

Common

• Headache (often transient as tolerance develops).
• Dizziness or light‑headedness, especially on standing (orthostatic hypotension).
• Flushing of the face and neck.
• Nausea or mild gastrointestinal discomfort.

Rare

• Palpitations or tachycardia.
• Hypotensive syncope.
• Severe headache unresponsive to analgesics.

Serious

• Life‑threatening hypotension leading to shock.
• Methemoglobinemia (extremely rare, characterized by cyanosis and dyspnea).

Drug–Drug Interactions

• Phosphodiesterase‑5 inhibitors (sildenafil, tadalafil, vardenafil): synergistic vasodilation → contraindicated.
• Other nitrates (isosorbide dinitrate, nitroglycerin): additive effect → may require dose adjustment or avoidance.
• Antihypertensives (ACE inhibitors, ARBs, β‑blockers): can enhance blood‑pressure‑lowering effect; monitor for symptomatic hypotension.
• Alcohol: potentiates vasodilatory response, increasing dizziness.
• Azole antifungals (ketoconazole, itraconazole): inhibit hepatic metabolism, potentially raising plasma levels; use with caution.

Patients should disclose all concomitant medications, including over‑the‑counter supplements, to their healthcare provider.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing for adults is 20 mg to 60 mg taken once daily in the morning. The exact dose is individualized based on symptom control and tolerability.
• Missed dose: If a dose is forgotten and the scheduled time for the next dose is more than 12 hours away, take the missed tablet. If it is closer to the next scheduled dose, skip the missed tablet and resume the regular schedule. Do not double‑dose.
• Overdose: Symptoms may include severe hypotension, profound headache, and fainting. Immediate medical attention is required. Supportive care (intravenous fluids, vasopressors) is the mainstay of treatment; there is no specific antidote.

Precautions

• Take Monoket with a full glass of water; food does not significantly affect absorption, but a high‑fat meal may delay onset slightly.
• Avoid abrupt positional changes that can precipitate orthostatic dizziness.
• Limit alcohol intake, as it intensifies vasodilatory side effects.
• In patients with hepatic or renal impairment, consider initiating therapy at the lower end of the dosing range (20 mg).

FAQ

• Is Monoket available in both brand‑name and generic forms in Hong Kong?
  Yes. The brand‑name product Imdur and the generic formulation Monoket both contain Isosorbide Mononitrate. The generic version is typically less expensive while delivering identical therapeutic effects.

• Does Monoket require refrigeration or any special storage conditions?
  No refrigeration is needed. Store the tablets at a controlled room temperature (15 °C–30 °C), protected from excess moisture, direct sunlight, and heat sources.

• What does the tablet look like, and how can I identify the strength?
  Monoket tablets are film‑coated, round, and come in three strengths: 20 mg (pink), 40 mg (blue), and 60 mg (white). The imprint code on each tablet identifies the manufacturer and strength; refer to the packaging insert for exact details.

• Can I travel internationally with Monoket, and are there any customs restrictions?
  Yes, you may carry a personal supply for up to 30 days, provided the medication is in its original packaging with a label. Hong Kong permits personal import of up to a three‑month supply for personal use, but larger quantities may require a import licence.

• Are there any specific warnings for Asian populations taking Isosorbide Mononitrate?
  Pharmacokinetic studies have not identified clinically meaningful differences between Asian and non‑Asian patients. However, clinicians should monitor for hypotension in elderly individuals, who are prevalent in Asian societies, and adjust the dose accordingly.

• What are the major differences between Monoket formulations sold in the US, EU, and Asia?
  The API and dosage strengths are identical worldwide. Minor formulation differences may include the inactive filler (e.g., lactose vs. microcrystalline cellulose) and tablet coating colors, which are regulated by regional pharmacopeias.

• How does Monoket compare to older nitrates such as nitroglycerin tablets?
  Unlike short‑acting nitroglycerin, Monoket provides a steady release of nitrate for up to 24 hours, eliminating the need for multiple daily doses. It also has a more predictable absorption profile and does not require sublingual administration.

• Is there any evidence that Monoket improves long‑term cardiovascular outcomes?
  Large randomized trials for isosorbide mononitrate (e.g., the ISMN Coronary Trial) demonstrated symptomatic relief of angina but did not show a reduction in mortality. The drug remains valuable for quality‑of‑life improvement when combined with other GDMT components.

• Can Monoket be taken with dietary supplements such as L‑arginine or coenzyme Q10?
  These supplements may modestly increase nitric oxide availability, potentially enhancing the vasodilatory effect. While no severe interactions have been reported, patients should inform their healthcare provider to monitor blood pressure.

• What testing, if any, is required before starting Monoket therapy?
  Baseline blood pressure measurement, renal function assessment (serum creatinine or eGFR), and a review of current medications are standard. An electrocardiogram may be performed to document baseline cardiac rhythm, especially in patients with arrhythmia risk.

• Does Monoket affect common drug‑testing panels (e.g., employment or sports testing)?
  Nitrates are not screened for in standard workplace or sports drug tests, as they are not prohibited substances.
