When should anticholinesterases be given in relation to food?

Anticholinesterases should be administered with food, specifically 1/2 hour before meals. This timing is important for a couple of reasons. First, taking anticholinesterases with food can help to enhance the absorption of the medication and minimize gastrointestinal side effects that may occur when the medication is taken on an empty stomach. Additionally, administering the medication before meals can optimize the therapeutic effects during the time of food intake, especially for conditions like myasthenia gravis, where muscle strength may be most needed during and shortly after eating.

Considering the other options, taking the medication without food could lead to discomfort and malabsorption. Administering it after meals might miss the optimal timing for effectiveness, as the drug could reach peak levels too late for muscle support during or right after eating. Taking the medication only during meals may not allow for adequate absorption and could lead to reduced effectiveness. Therefore, giving anticholinesterases 1/2 hour before meals is the most advantageous timing to ensure optimal effectiveness while minimizing potential side effects.
