Tamsulosin 0.4 mg daily
Amiodarone 400 mg daily
ST denies the use of herbal products or OTC medications. He denies tobacco use but admits to social drinking. His family history is significant for hypertension. The pulmonologist for whom ST works is concerned about ST's symptoms and performs a physical examination, along with laboratory work. ST's vital signs are reported as follows:
blood pressure, 150/95 mm Hg;
heart rate, 90 beats/min,
temp 98.6°F, and respiratory rate, 20 breaths/min.
The exam is unremarkable, with no signs of pulmonary congestion, lower extremity edema, or signs of infection. The basic metabolic panel and complete blood count are within normal limits. The only lab result found to be outside of normal limits is an elevated erythrocyte sedimentation rate (ESR). The pulmonologist is concerned that ST's medications may be causing pulmonary problems. He performs a bronchoscope to obtain a lung biopsy, which demonstrates diffuse alveolar damage and fibrosis.
