Description

Tamsulosin CAS NO 106133-20-4 is a selective α-1A and α-1D adrenergic receptor antagonist. This compound is of critical importance as the active pharmaceutical ingredient (API) in medications used to treat benign prostatic hyperplasia (BPH). It is primarily required by pharmaceutical manufacturers and research institutions for the formulation of finished dosage forms and for clinical studies. Our high-purity Tamsulosin ensures reliable performance and consistency in your production processes.

Application

• Pharmaceutical API: Primary use as the active ingredient in prescription medications for the symptomatic treatment of benign prostatic hyperplasia (BPH).
• Generic Drug Manufacturing: Sourcing for the production of generic tamsulosin hydrochloride capsules and tablets.
• Clinical Research: Utilization in preclinical and clinical studies for urological disorders.
• Formulation Development: Used in R&D for developing new drug delivery systems and dosage forms.
• Reference Standard: Serves as a chemical reference standard in analytical laboratories for quality control testing.
