SMS 201-995 and variceal haemorrhage

Sandostatin (SMS 201-995) was evaluated in the treatment of variceal bleeding in 9 patients with liver cirrhosis and portal hypertension who were undergoing injection sclerotherapy following a variceal haemorrhage. SMS 201-995 reduced directly recorded intravariceal pressure by 38%, whereas reductions in the wedged hepatic venous pressure were around 17%. These observations suggest that SMS 201-995 may prove useful in treating bleeding oesophageal varices in the acute situation. Preliminary, promising data are shown in the results of a randomized controlled clinical trial in which SMS 201-995 plus injection sclerotherapy vs injection sclerotherapy are compared in patients with bleeding oesophageal varices. Furthermore, in experimental work associated stimulating effects of SMS 201-995 are shown on the function of the reticulo-endothelial system both in the liver and peripherally. These effects may prove useful by reducing the effects of endotoxaemia and possibly result in arresting further liver damage.
