Feedback: Cromolyn (Nasalcrom) inhibits the release of histamine and other chemicals. It is prescribed to treat allergic rhinitis. Antiarrythmic medications are used to treat atrial and ventricular dysrrythmias. HMG-CoA reductase inhibitors are used to lower blood cholesterol by competitively inhibiting the rate-limiting enzyme in the liver.
