Midodrin Evolan (Midodrine Hydrochloride)

Midodrine Hydrochloride, the active ingredient in Midodrin Evolan, is an alpha-1 adrenergic agonist presented as an oral tablet for oral use. It is used to raise standing blood pressure in patients who experience orthostatic hypotension.

GNH USA supplies Midodrin Evolan as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Midodrine Hydrochloride acts on the peripheral vascular alpha‑1 receptors to treat conditions characterized by low standing blood pressure.

- Orthostatic hypotension: increases standing systolic pressure and reduces dizziness and fainting episodes. - Neurogenic orthostatic hypotension: improves vascular tone in patients with autonomic failure, helping maintain cerebral perfusion. - Syncope due to hypotension: lessens the frequency of fainting attacks caused by inadequate blood pressure when upright.

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

Common Side Effects: - Piloerection (goose‑flesh skin) - Itching or rash - Urinary retention - Supine hypertension - Headache - Nausea

Serious or Rare Side Effects: - Severe hypertension, especially when lying down - Bradycardia or other arrhythmias - Ischemic cardiac events - Allergic reactions including angioedema - Peripheral ischemia - Thromboembolic events

When prescribing Midodrine, clinicians should consider several safety measures to minimize risk.

- Blood pressure monitoring: check supine and standing pressures regularly. - Cardiac disease: avoid in patients with severe heart failure or uncontrolled hypertension. - Renal impairment: adjust dose or monitor closely in reduced kidney function. - Concomitant antihypertensives: review and possibly reduce other blood‑pressure‑lowering agents. - Pregnancy: risk category unknown; use only if potential benefit justifies potential risk. - Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Midodrine can interact with several drug classes, influencing its efficacy and safety profile.

Major Interactions (Avoid): - Other vasopressors (e.g., phenylephrine) – additive hypertensive effect. - Monoamine oxidase inhibitors – risk of excessive vasoconstriction. - Tricyclic antidepressants – may potentiate blood‑pressure rise.

Moderate Interactions (Monitor Closely): - Diuretics – may enhance orthostatic hypotension when combined. - Beta‑blockers – can blunt compensatory heart‑rate response. - ACE inhibitors or ARBs – may require blood‑pressure monitoring for additive effects.
