Product Introduction

Bioactivity
Description
Tamsulosin hydrochloride (Flomax hydrochloride) is the hydrochloride salt of tamsulosin, a sulfonamide derivative with α1 adrenergic antagonist activity.
In vivo
Tamsulosin exhibits high plasma-protein binding, largely to α1-acid glycoprotein. It is metabolized, mainly by cytochrome P450 (CYP) 3A4 and CYP2D6 to compounds with low abundance, and 8.7–15% of an oral dose is excreted renally as the parent compound. The pharmacokinetics of tamsulosin are not affected to a major extent by age, and pharmacokinetic alterations in renally impaired patients relate largely to an increased concentration of α1-acid glycoprotein. Pharmacokinetic alterations with hepatic impairment are also only moderate, thus neither renal nor mild to moderate hepatic impairment necessitates dose adjustment. Early studies of tamsulosin IR in experimental animals, such as rats and dogs, showed rapid absorption of tamsulosin after oral administration (within 30–90 minutes) but absolute bioavailability of only 7–23% in rats and 30–42% in dogs. The absolute bioavailability of tamsulosin MR in fasted humans is approximately 100%. The tmax is typically about 5 hours (reported range of mean values 2.9-5.6 hours) in the fasted state and about 6 hours in the fed state (range 5.2-7.0 hours). Animal studies involving intravenous injection of radiolabelled tamsulosin and measurement of radiolabel in various tissues after 10 minutes have shown the presence of the drug in various tissues, ranked in the following order: kidney>lung≈heart>submaxillary gland>liver ≈spleen≈aorta≈vas deferens> prostate>>cerebral cortex, the latter being close to detection limits. Tamsulosin may not pass the blood-brain barrier.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
