Study Notes
Therapeutic Systems
- Therapeutic systems are designed to deliver drugs in a specific dosage form, ensuring medication release at a predetermined site and time.
Types of Delivery Systems
- Newer drug delivery systems (NODS) enhance therapeutic efficacy by providing controlled rates of drug release and targeted therapies.
- Controlled rate and targeted therapy improve bioavailability and extend the duration of action, particularly effective against tumors.
- Example: L Depa significantly enhances drug action.
- These systems minimize fluctuations in drug concentration, facilitating effective crosses across the blood-brain barrier.
Adverse Effects of Delivery Systems
- Oral drug delivery methods include:
- Injectable for immediate effect.
- Mucosal applications for localized effect.
- Topical options like transdermal patches for sustained action.
- Needle-based alternatives consist of:
- Nasal delivery for active absorption.
- Needle-free methods such as buccal (passive) and pulmonary routes.
- Other delivery routes include:
- Ocular applications for eye-specific treatments.
- Vaginal and anal routes for localized drug effects.
Sensitivity of Drug Consumption
- Clinical challenges include:
- Lower amounts of dosage reaching the target site, reducing therapeutic effectiveness.
- Necessity for repeated dosages, which may impact overall treatment adherence.
- Decreased patient compliance can arise from complex dosing regimens.
- Fluctuations in drug concentration within the bloodstream may lead to ineffective treatment or adverse reactions.
