Butorphanol tartrate, a synthetic opioid agonist-antagonist analgesic previously available for injection, is now being marketed as a nasal spray (Stadol-NS - Mead Johnson). The spray was approved by the US Food and Drug Administration (FDA) for any type of pain for which an opioid analgesic is appropriate, but the manufacturer is emphasizing use for treatment of migraine headache and postoperative pain. Drugs for pain were reviewed in the Medical Letter, volume 35, page 1, January 8, 1993.

Valacyclovir (Valtrex - Glaxo Wellcome), an L- valyl ester of acyclovir (Zovirax), has been approved by the US Food and Drug Administration (FDA) for oral treatment of herpes zoster (shingles) in immunocompetent adults.

According to the manufacturer, the Respimat device improves delivery of tiotropium to the lungs because, unlike with the Handihaler, it is not dependent on the strength of the patient’s breath intake.
