Pharmacokinetics and dose proportionality of beclomethasone from three strengths of a CFC-free beclomethasone dipropionate metered-dose inhaler

As part of a development program to offer alternatives to chlorofluorocarbon (CFC) containing metered-dose inhalers, beclomethasone dipropionate has been formulated in a CFC-free system at three strengths: 50, 100, and 200 micrograms/actuation ex valve. To measure serum levels and dose proportionality of the beclomethasone derived from beclomethasone dipropionate, 13 mild to moderate asthmatic patients received a single dose of eight inhalations from each strength according to a double-blind crossover design. Seven patients were studied over 4 h and six patients over 12 h. For the total doses of 400, 800, and 1600 micrograms studied over 12 h, Cmax and AUC increased in a ratio of 1:1.8:3.1. A good correlation was seen between the fine-particle mass delivered and the in vivo performance of the three strengths. From a clinical point of view, the predictable increases in serum levels with an increase in dose will permit the clinician to effectively titrate a patient with this product.

[Hohmann's procedure for epicodylitis humeri ulnaris (author's transl)]

Report about 4 operations using Hohmann's procedure in therapy-resistent epicondylitis humeri ulnaris. The ulnar nerve was not seen during operation. The intervention is as simple as on the radial side. It can be recommended.

[Myelography--what is it really worth?]

The routinelike employment of myelography is attached and as follows established. 1. Primum non nocere! This old medical axiom also here has its validity, there are enough examples of incidents and late damages in employment of this method. 2. The myelography is not reliable. Errors are described. 3. Superfluous painful examinations should be spared for the patient: operation and myelography are two interventions. 4. The myelography costs time and prolongs staying in hospital.
