  • Title: [Gastroduodenal tolerance of tenoxicam versus diclofenac-Na: an endoscopy double-blind controlled study in healthy probands].

    Journal: Z Rheumatol; 1989; 48(5):243-5. PubMed ID: 2692344.
    Abstract:
    The gastroduodenal tolerability of tenoxicam vs diclofenac-Na was evaluated in a double-blind, parallel group study in 36 healthy male volunteers. The doses used were 20 mg tenoxicam vs 100 mg diclofenac-Na in a retard formulation daily over a period of 14 days. Gastric tolerability was assessed by using upper endoscopy. Gastroscopy was performed at base-line after the dosing period of 14 days and again after a follow-up period of 14 days without any treatment. The mucosal lesions were scored using modified Lanza criteria. In comparison to diclofenac-Na, tenoxicam was significantly better tolerated after a 14-day dosing period (mean gastric score: tenoxicam: 1.3 +/- 0.7; diclofenac-Na: 2.2 +/- 1.1 p = 0.0143). Both treatment groups had comparable scores at base-line and post-study assessments. Tenoxicam and diclofenac-Na were generally well tolerated. Only two volunteers reported intermittent lack of appetite, heartburn, and a feeling of pressure in the stomach. In summary, tenoxicam given as a 20 mg single oral morning dose over a 14-day period was significantly better tolerated than diclofenac 100 mg with regard to gastroduodenal mucosal damage.
