Tiotropium: an inhaled, long-acting anticholinergic drug for chronic obstructive pulmonary disease.

Inhaled anticholinergic drugs are considered one of the principal bronchodilator treatments for chronic obstructive pulmonary disease (COPD). Ipratropium bromide is an anticholinergic drug frequently administered for the treatment of COPD. Unfortunately, ipratropium has a short duration of action, requiring administration every 6 hours; this regimen affects adherence to drug therapy.

Insulin glargine: a new long-acting insulin product.

The pharmacodynamics, pharmacokinetics, clinical efficacy, adverse effects, and dosage and administration of insulin glargine are reviewed. Current treatment regimens for patients with type 1 diabetes mellitus and some with type 2 are designed to provide a basal insulin level with intermittent preprandial insulin coverage. Insulin glargine precipitates after subcutaneous injection, slowing absorption.
