Midodrine Hydrochloride Teva Uk (Midodrine Hydrochloride)

Midodrine is used to manage conditions related to low blood pressure by activating α1‑adrenergic receptors.

• Orthostatic hypotension: increases standing systolic pressure and reduces dizziness.
• Neurogenic orthostatic hypotension: improves cerebral perfusion in patients with autonomic failure.
• Chronic orthostatic intolerance: helps maintain blood pressure during prolonged standing.

• Midodrine is a prodrug that is rapidly converted to desglymidodrine, a selective α1‑adrenergic receptor agonist. Binding to peripheral α1 receptors induces vasoconstriction of arterioles and veins, which raises systemic vascular resistance and consequently increases arterial blood pressure, alleviating symptoms of hypotension.

Midodrine may cause a range of adverse reactions, most of which are dose‑related and reversible.

Common Side Effects

• Piloerection (goose‑flesh skin).
• Scalp tingling or itching.
• Urinary retention.
• Supine hypertension.
• Nausea or abdominal discomfort.

Serious or Rare Side Effects

• Severe hypertension, especially when lying down.
• Bradycardia or arrhythmias.
• Myocardial infarction or other acute cardiac events.
• Anaphylactic or severe allergic reactions.
• Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Before prescribing Midodrine, clinicians should evaluate patient‑specific risk factors and monitor for adverse events.

• Blood pressure monitoring: check supine and standing pressures regularly.
• Supine positioning: advise patients to avoid lying flat for extended periods.
• Cardiovascular disease: use caution in patients with ischemic heart disease or uncontrolled hypertension.
• Renal or hepatic impairment: consider dose adjustment or increased monitoring.
• Contraindications: do not use in patients with pheochromocytoma or severe organic heart disease.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Midodrine can interact with several drug classes, altering its pressor effect or increasing the risk of hypotension or hypertension.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): may precipitate hypertensive crisis.
• Other α1‑adrenergic agonists (e.g., phenylephrine): additive pressor effect.
• Diuretics: can exacerbate orthostatic hypotension.

Moderate Interactions (Monitor Closely):\n- Beta‑blockers: may blunt compensatory tachycardia.

• Anticholinergic agents: increase risk of urinary retention.
• ACE inhibitors or ARBs: may enhance hypotensive response.
• Tricyclic antidepressants: can affect vascular tone.
