CXR clearance is slightly higher in the presence of methylphenidate, and slightly lower in the presence of amphetamine.7 Due to these varying pharmacokinetic properties, the manufacturer of CXR warns against the substitution of immediate-release tablets in place of the extended-release formulation.6 The XR formulation should be swallowed whole, not crushed or chewed. Researchers are still uncertain exactly how clonidine helps treat ADHD, but it may work by acting on the part of the brain that influences inattentiveness, hyperactivity, and impulsivity.

Doctors classify clonidine as a nonstimulant, making it a second-line ADHD medication. (2014). The activity of these medications has been attributed to their effects on pre- and post-synaptic alpha-2 receptors, particularly as they relate to the prefrontal cortex (PFC) and its mediation of key ADHD symptoms, such as inattention, distractibility, and impulsivity.2,3 While both medications work specifically on the alpha-2 receptors, differences in binding affinity and selectivity between the two medications may lead to differences in side effect profiles.2 Regardless of these differences, both clonidine and guanfacine are used frequently in the treatment of ADHD, whether as adjuncts for patients with a partial response to treatment with stimulants or atomoxetine, or as monotherapy in patients who are unable to tolerate other medications used in the treatment of ADHD.
