Hypovase (Prazosin)

Prazosin, the active ingredient in Hypovase, is a Alpha-1 adrenergic receptor antagonist presented as an unknown/unknown for oral use. It treats hypertension and benign prostatic hyperplasia in adult patients.

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

Prazosin acts on the alpha‑1 adrenergic pathway to lower vascular resistance and relax smooth muscle in the prostate. - Hypertension: reduces systolic and diastolic blood pressure by vasodilation. - Benign prostatic hyperplasia: eases urinary outflow by relaxing prostatic smooth muscle. - Post‑traumatic stress disorder: alleviates nightmares and sleep disturbances by modulating central adrenergic activity.

Adverse reactions may vary in frequency and severity.

Common Side Effects: - Dizziness: feeling light‑headed, especially after standing. - Headache: mild to moderate intensity. - Fatigue: general tiredness or lack of energy. - Nasal congestion: blocked or runny nose. - Palpitations: awareness of heartbeat. - Nausea: upset stomach or urge to vomit.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure causing fainting. - Syncope: sudden loss of consciousness. - Priapism: prolonged, painful erection. - Allergic reaction: rash, itching, swelling, or difficulty breathing. - Liver injury: jaundice, dark urine, or elevated liver enzymes.

Before initiating therapy, consider the following safety measures. - Blood pressure monitoring: check regularly to avoid excessive hypotension. - Initiate low dose: start with the smallest effective dose and titrate gradually. - Discontinue cautiously: avoid abrupt cessation to prevent rebound hypertension. - Cardiac disease caution: use carefully in patients with heart failure or coronary artery disease. - Hepatic impairment: dose adjustment may be required in severe liver dysfunction. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Prazosin may interact with other medicines, altering its effect or safety profile.

Major Interactions (Avoid): - Concurrent antihypertensives (e.g., ACE inhibitors, ARBs): additive blood‑pressure lowering effect. - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): risk of profound hypotension. - Clonidine withdrawal: may precipitate severe hypertension.

Moderate Interactions (Monitor Closely): - Diuretics: may enhance orthostatic hypotension. - Non‑steroidal anti‑inflammatory drugs (NSAIDs): can blunt antihypertensive response. - CYP3A4 inhibitors (e.g., ketoconazole): may increase prazosin plasma levels. - Alcohol: can intensify dizziness and hypotension.
