Moxonidine Teva Uk (Moxonidine)

• Moxonidine is used to manage hypertension by targeting central sympathetic pathways.
• Essential hypertension: reduces systolic and diastolic blood pressure in patients with primary hypertension.
• Resistant hypertension: provides additional blood pressure control when standard therapies are insufficient.
• Hypertension with sympathetic overactivity: attenuates central sympathetic tone to improve blood pressure regulation.

• Moxonidine selectively stimulates central imidazoline I1 receptors located in the rostral ventrolateral medulla. Activation of these receptors inhibits sympathetic outflow, leading to decreased peripheral vascular resistance, reduced heart rate, and lowered renin release, which collectively contribute to a reduction in arterial blood pressure. The drug’s high receptor specificity minimizes interaction with α2‑adrenergic receptors, offering a favorable side‑effect profile compared with older centrally acting agents.

Moxonidine may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

• Dry mouth: sensation of oral dryness.
• Fatigue: feeling of tiredness or reduced energy.
• Dizziness: light‑headedness, especially upon standing.
• Headache: mild to moderate cranial pain.
• Nausea: upset stomach with urge to vomit.

Serious or Rare Side Effects

• Severe hypotension: marked drop in blood pressure leading to fainting.
• Bradycardia: abnormally slow heart rate.
• Hepatic dysfunction: elevated liver enzymes or jaundice.
• Allergic reactions: rash, itching, swelling, or anaphylaxis.

• When prescribing Moxonidine, clinicians should observe several precautionary measures to ensure safe use.
• Blood pressure monitoring: check baseline and periodic readings to avoid excessive hypotension.
• Renal impairment: adjust dose or use with caution in patients with reduced kidney function.
• Hepatic impairment: consider dose reduction in those with liver disease.
• Elderly patients: start at low dose and monitor for dizziness or falls.
• Discontinuation: avoid abrupt cessation; taper gradually to prevent rebound hypertension.
• Store at room temperature: keep below 25 °C, retain in original packaging, protect from moisture.

Moxonidine can interact with other medicines, altering its antihypertensive effect or safety profile.

Major Interactions (Avoid)

• Clonidine: additive central hypotensive effect may cause severe blood pressure drop.
• Other imidazoline agonists (e.g., guanfacine): combined use can lead to excessive hypotension.
• Strong CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): may increase plasma concentrations of moxonidine.

Moderate Interactions (Monitor Closely)

• Diuretics: concurrent use may enhance antihypertensive response, requiring blood pressure monitoring.
• ACE inhibitors or ARBs: combined therapy can increase risk of hypotension.
• NSAIDs: may attenuate the blood‑pressure‑lowering effect of moxonidine.
• Beta‑blockers: additive effect on heart rate and blood pressure, warranting dose adjustments.
