Update on methylphenidate and dexmethylphenidate formulations for children with attention-deficit/hyperactivity
1University of Maryland School of Pharmacy, Baltimore, MD, USA.
This review evaluates extended-release methylphenidate and dexmethylphenidate formulations for attention-deficit/hyperactivity disorder (ADHD). Understanding formulation differences is key for effective ADHD treatment and symptom management.
Area of Science:
- Pharmacology
- Neuroscience
- Clinical Pharmacy
Background:
- Methylphenidate is a primary treatment for ADHD.
- Short half-life necessitates extended-release formulations.
- Various intermediate- and long-acting products exist.
Purpose of the Study:
- Evaluate current literature on safety and efficacy.
- Assess intermediate- and long-acting methylphenidate/dexmethylphenidate formulations for ADHD.
- Provide guidance on medication selection.
Main Methods:
- Literature review of existing studies.
- Analysis of pharmacokinetic and adverse effect data.
- Comparison of different extended-release mechanisms.
Main Results:
- Extended-release products show similar efficacy to immediate-acting forms.
- Pharmacokinetics and adverse effects vary among formulations.
- Some intermediate-acting products still require twice-daily dosing.
- Long-acting products include novel delivery systems (controlled-release, bimodal, patch).
Conclusions:
- Knowledge of methylphenidate/dexmethylphenidate formulations is vital for ADHD treatment.
- Understanding release mechanisms and pharmacokinetics aids appropriate product selection.
- Optimizing ADHD symptom control relies on informed medication choices.

Adrenergic Agonists: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
