Diarrhea | Prospective Randomized Open Label Study of the Treatment of Therapy-associated Diarrhea During Percutaneous Radiation Therapy of the Small Pelvis. - Comparison of Loperamide and Tincture of Opium -

Diarrhea research study

What is the primary objective of this study?

Therapy-associated diarrhea during radiation therapy of small pelvis (including enteritis as a result of radiation therapy and enteritis as a result of radiation- and chemotherapy) is a common problem in multimodal cancer therapy. We investigate the therapeutic effect of either loperamide or tinctura opii in therapy- associated diarrhea in patients who receive radiation therapy of the small pelvis with or without chemotherapy.

This includes patients with following malignancies: rectal carcinoma, prostate carcinoma, endometrial carcinoma, cervix carcinoma. - Diarrhea grade 1 and grade 2 (Classification NCI-CTCAE Version 3.0) - ECOG-Grade 0-2 - Enlightenment and written declaration of consent to the participation.

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:Opii normata treatmentAfter beginning of diarrhea grade 1: 5 drops tincture of opium three times a day After beginning of diarrhea grade 2: Intensive therapy with 15 drops tincture of opium three times a day.

Drug:Loperamid TreatmentAll patients who receive as a result of randomisation loperamide After beginning of diarrhea grade 1: Initial 4mg and 2mg after any unformed stool. The maximum dose amounts to16mg per day. After beginning of diarrhea grade 2: Intensive therapy with 2mg loperamide every 2 h. The maximum dose amounts to 16mg per day.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
