General Information

Tamsulosin Impurities and Tamsulosin

Daicel Pharma provides a wide selection of high-quality Tamsulosin impurity standards, including N-Nitroso Tamsulosin Impurity. These impurities are vital in evaluating the active pharmaceutical ingredient Tamsulosin’s quality, stability, and biological safety. Moreover, Daicel Pharma can synthesize Tamsulosin impurities based on specific customer requirements, ensuring reliable delivery worldwide.

Tamsulosin [CAS: 106133-20-4] treats the signs and symptoms of benign prostatic hyperplasia (BPH). It belongs to a class of alpha-1 adrenergic blockers. This drug is for conditions such as ureteral stones, prostatitis, and female voiding dysfunction.

Tamsulosin: Use and Commercial Availability  

Tamsulosin, a specific antagonist of alpha-1A and alpha-1B adrenoceptors, primarily acts on the prostate and bladder found in these receptors. It manages symptoms associated with benign prostatic hypertrophy. By blocking these receptors, it induces smooth muscle relaxation in the prostate and detrusor muscles of the bladder, resulting in improved urinary flow.

Tamsulosin is available under Flomax, which contains the active ingredient Tamsulosin.

Tamsulosin Structure and Mechanism of Action Tamsulosin Structure and Mechanism of Action

The chemical name of Tamsulosin is 5-[(2R)-2-[[2-(2-Ethoxyphenoxy)ethyl]amino]propyl]-2-methoxybenzenesulfonamide. Its chemical formula is C20H28N2O5S, and its molecular weight is approximately 408.5 g/mol

Tamsulosin blocks alpha-1D adrenoceptors and relaxes the detrusor muscles of the bladder.

Tamsulosin Impurities and Synthesis

During the synthesis1 and storage of Tamsulosin, various impurities such as related substances, degradation products, and residual solvents can form. It is crucial to diligently monitor and control these impurities to ensure the medication’s safety, effectiveness, and overall quality.

Daicel Pharma provides a comprehensive Certificate of Analysis (CoA) for Tamsulosin impurity standards, such as N-Nitroso Tamsulosin Impurity. These impurities are produced strictly with current Good Manufacturing Practices (cGMP). The CoA comprises detailed characterization data, such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity2, offering a thorough understanding of the impurity profile. Upon request, Daicel can also supply 13C-DEPT data for further characterization.

Additionally, Daicel Pharma possesses the technical expertise to synthesize any unknown impurities or degradation products of Tamsulosin. We also offer labeled compounds that help assess the efficacy of generic versions of Tamsulosin. For bioanalytical research and BA/BE studies, we also provide deuterium-labeled Tamsulosin standards such as Tamsulosin D4 and N-Nitroso-Tamsulosin d4 Impurity (Mixture of isomers).
