Answer: Atenolol is included in a class of drugs called beta-blockers. Beta-blockers do have the potential ability to increase glucose by inhibiting the release of insulin. Other potential problems with diabetics include masking of low sugar symptoms and blunting of the return of glucose after an excessively low sugar. Some beta-blockers like atenolol are selective beta-blockers and have less of these effects, particularly in doses under 100mg. In practice, 25mg of atenolol would not be expected to have too many effects on a diabetic. Methamphetamine has no such direct effect on insulin.

Atenolol can aggravate breathing difficulties in patients with asthma, chronic bronchitis, or emphysema. In patients with existing slow heart rates (bradycardias) and heart blocks (defects in the electrical conduction of the heart), atenolol can cause dangerously slow heart rates, and even shock. Atenolol reduces the force of heart muscle contraction and can aggravate symptoms of heart failure.

Atenolol should not be given if congestive heart failure is not under control. It must be given with great care. A low initial dose is given, increasing gradually and continuing for several months.

Atenolol is almost exclusively eliminated renally and is well removable by dialysis. A compromised liver function does not lead to higher peak-activity and/or a longer halflife with possible accumulation. However, preexisting renal insufficience of higher degree makes dose-reductions necessary (see below)
