Description

Tamsulosin Hydrochloride 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 clinical studies. Our supply ensures high purity and consistent quality for global pharmaceutical applications.

Application

• Pharmaceutical API: Primary use as the active ingredient in prescription medications for the treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH).
• Generic Drug Manufacturing: Sourcing for the production of generic tamsulosin hydrochloride capsules and tablets.
• Clinical Research: Utilization in bioavailability, bioequivalence, and new formulation development studies.
• Reference Standard: Serves as a high-purity chemical reference standard for quality control laboratories.
• Drug Discovery: Used in pharmacological research to study α-adrenergic receptor mechanisms and related pathways.

Quality Control

Our Tamsulosin Hydrochloride is manufactured and tested to meet stringent pharmacopeial standards. Quality assurance protocols are designed to ensure identity, purity, strength, and composition. The product is typically tested against specifications aligned with USP (United States Pharmacopeia) and EP (European Pharmacopoeia) monographs where applicable. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each batch to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
