Description
Overview of the medicine
D-Dopa is the D-isomer of dihydroxyphenylalanine. Unlike its L-isomer (L-Dopa), D-Dopa does not readily cross the blood-brain barrier and has no established therapeutic indications for conditions like Parkinson's disease. Its pharmacological properties are largely investigational, often studied for peripheral effects or as a comparator in research. The 250 mg tablet is a hypothetical formulation for specific experimental applications.
Uses & Indications
Dosage
Adults
No standard therapeutic dosage established. Dosage determined by specific research protocol.
Elderly
No standard therapeutic dosage established. Dosage determined by specific research protocol.
Renal_impairment
No standard therapeutic dosage established. Use with caution in renal impairment, as per research protocol.
How to Take
Oral administration. Follow specific guidelines of the research protocol. Typically swallowed whole with water.
Mechanism of Action
The mechanism of action of D-Dopa in humans for therapeutic purposes is not well-established. It can be decarboxylated to D-dopamine peripherally, but this D-isomer of dopamine is generally considered to be inactive or have minimal effects at typical dopaminergic receptors compared to L-dopamine. It primarily lacks significant central nervous system activity due to poor blood-brain barrier penetration.
Pharmacokinetics
Onset
Not established for therapeutic effects.
Excretion
Renal excretion of unchanged drug and its inactive metabolites.
Half life
Specific human half-life not established, likely short due to rapid metabolism.
Absorption
Oral absorption is expected but human bioavailability and specific absorption sites are not well-defined for therapeutic use. Subject to first-pass metabolism.
Metabolism
Primarily hepatic metabolism, likely involving Dopa decarboxylase peripherally. Metabolites are generally pharmacologically inactive.
Side Effects
Contraindications
- •Hypersensitivity to D-Dopa or any component of the formulation.
- •Lack of established safety and efficacy for therapeutic use in human patients.
Drug Interactions
Monoamine Oxidase Inhibitors (MAOIs)
Potential for indirect interaction if D-dopamine is formed and accumulates peripherally.
Peripheral Dopa Decarboxylase Inhibitors
May alter D-Dopa metabolism and systemic exposure if taken concurrently.
Storage
Store below 30°C in a dry place, protected from light and moisture. Keep out of reach of children and unauthorized personnel. Store as per research protocol requirements.
Overdose
Information on D-Dopa overdose is very limited due to its investigational status. Management would be symptomatic and supportive, based on any observed adverse effects in a controlled research setting.
Pregnancy & Lactation
Safety in pregnancy and lactation has not been established. Avoid use unless specifically required for research under strict ethical guidelines and risk-benefit assessment.
