Eurasian J Med. 2017 Oct;49(3):188-192. doi: 10.5152/eurasianjmed.2017.17046.

OBJECTIVE: In our study, the effects of glycosylated protein cross-link breaker, alagebrium was investigated on isolated rat carotid artery using myography. Alagebrium showed vasodilator effect on carotid artery rings; particularly, this effect was significantly increased in endothelium-intact rings.MATERIALS AND...

A computational procedure for assessing the dynamic performance of diffusion-controlled transdermal delivery devices.

Pharmaceutics

Simon L.
PMID: 24310592
Pharmaceutics. 2011 Aug 11;3(3):485-96. doi: 10.3390/pharmaceutics3030485.

The dynamic performances of two different controlled-release systems were analyzed. In a reservoir-type drug-delivery patch, the transdermal flux is influenced by the properties of the membrane. A constant thermodynamic drug activity is preserved in the donor compartment. Monolithic matrices...

Is it time to replace propranolol with carvedilol for portal hypertension?.

World journal of gastrointestinal endoscopy

Abid S, Ali S, Baig MA, Waheed AA.
PMID: 25992192
World J Gastrointest Endosc. 2015 May 16;7(5):532-9. doi: 10.4253/wjge.v7.i5.532.

Beta-adrenergic receptor antagonists (β-blockers) have been well established for use in portal hypertension for more than three decades. Different Non-selective β-blockers like propranolol, nadolol, timolol, atenolol, metoprolol and carvedilol have been in clinical practice in patients with cirrhosis. Carvedilol...

Metoprolol-induced Severe Liver Injury and Successful Management with Therapeutic Plasma Exchange.
