"The US Food and Drug Administration (FDA) has approved a new inhaled combination bronchodilator for long-term maintenance treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD), according to a company news "...
In studies with healthy volunteers of single doses up to 800 mg, adverse events were similar to those seen at lower doses but rates and severities were increased.
In cases of overdose, standard supportive measures should be adopted as required. Renal dialysis is not expected to accelerate clearance as sildenafil is highly bound to plasma proteins and it is not eliminated in the urine.
REVATIO is contraindicated in patients with:
- Concomitant use of organic nitrates in any form, either regularly or intermittently, because of the greater risk of hypotension [see WARNINGS AND PRECAUTIONS].
- Concomitant use of riociguat, a guanylate cyclase stimulator. PDE5 inhibitors, including sildenafil, may potentiate the hypotensive effects of riociguat.
- Known hypersensitivity to sildenafil or any component of the tablet, injection, or oral suspension. Hypersensitivity, including anaphylactic reaction, anaphylactic shock and anaphylactoid reaction, has been reported in association with the use of sildenafil.
