| Origin | Synthetic, Quinazoline derivative |
Maguran is a synthetic, prescription-only pharmaceutical preparation whose core active substance is Doxazosin, a compound derived from quinazoline. It belongs to the pharmacological class known as alpha-1 adrenergic blockers ( alpha1 -Adrenoceptor antagonists), acting as a systemic agent to influence specific nerve signals within the body. Maguran is classified primarily as an antihypertensive agent and a urological agent. Doxazosin lowers both systolic and diastolic blood pressure, and is among the established treatments for hypertension. This drug modulates vascular resistance to support cardiovascular health.
Maguran is a single-active-ingredient product supplied as an oral tablet, often available in standard or extended-release formulations to support consistent drug levels. The primary chemical entity is Doxazosin mesylate, formulated with solid tablet excipients, such as microcrystalline cellulose, to ensure stability and controlled release once administered. Doxazosin's mechanism of action involves selectively blocking the alpha-1 receptors, which induces peripheral vasodilation—the widening of blood vessels—and leads to a reduction in elevated blood pressure. Furthermore, this same muscle-relaxing effect is utilized to ease muscle tension in the prostate gland and the bladder neck. The utility of Doxazosin includes improving symptoms associated with urinary tract obstruction. The drug’s dual action provides a benefit for both circulatory health and improved urinary flow, making it an option in management strategies that require concurrent control of both issues.
