[A one-year prospective study of disodium etidronate versus 17 beta estradiol in the prevention of postmenopausal osteoporosis].

This prospective, controlled, nonrandomized, one-year trial in women included less than ten years after menopause was designed to compare the preventive efficacy on postmenopausal bone loss of replacement percutaneous 17 beta estradiol versus intermittent disodium etidronate. Twenty-five patients took oral disodium etidronate in a daily dosage of 200 mg in two-month courses separated by two-month intervals, with 1 g/day elemental calcium. Twenty-three patients used percutaneous 17 beta estradiol in daily dosage of 1.

[Chronotherapy of tenoxicam].

A study was carried out in order to investigate the chronotherapy (dosing time dependency) of an NSAID, the tenoxicam administered in ankylosing spondylitis, rheumatoid arthritis and osteoarthritis of the hip. These variations in efficacy exist as much for pain as for stiffness and maximum efficacy is obtained with administration at 8 am or 12 pm. Since the tolerance was good, we recommend midday as an optimal once-a-day dosing time.
