Health Policy OPEN
|June 29, 2023
Summary
Chinese physicians generally have positive perceptions of generic drugs, but knowledge gaps exist. Further education on generic drug consistency evaluations is crucial for policy success and cost reduction.
Area of Science:
- Pharmacoeconomics
- Health Policy
- Medical Education
Background:
- Global rise in generic drug utilization.
- China's commitment to generic drug consistency evaluations to boost substitution rates.
- Limited research on Chinese physicians' perspectives on generic drugs.
Purpose of the Study:
- To investigate the perceptions of physicians in China regarding generic drugs.
- To identify factors influencing physician attitudes towards generic medications.
Main Methods:
- Cross-sectional study conducted from June to July 2020.
- Online survey distributed via Sojump using convenience sampling.
- Analysis of 598 completed questionnaires.
Main Results:
- Physicians' perceptions of generic drugs are predominantly positive.
- Gaps in knowledge regarding generic drugs were identified.
- Some physicians expressed concerns about efficacy and side effect profiles compared to brand-name drugs.
- Significant variations in opinions were observed based on age, experience, education, specialty, and location.
Conclusions:
- Enhanced physician education on generic drug consistency evaluations is essential.
- Addressing knowledge gaps can support policy objectives for generic drug substitution.
- Facilitating physician understanding can contribute to reducing national healthcare costs.

01:16Bioequivalence: Overview
1.1K
Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...

01:17Drug Nomenclature
1.8K
During the development of a new pharmaceutical, the manufacturer initially assigns a code name to the drug. Once approved, the drug receives a United States Adopted Name (USAN)—a generic, nonproprietary designation. Upon being listed in the United States Pharmacopeia, this nonproprietary name becomes the drug's official name. Additionally, the manufacturer assigns a proprietary name or trademark, which serves as the brand name under which the drug is marketed. It is worth noting that...

Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

01:15Drug Abuse and Addiction: Pharmacological Phenomena
555
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

01:21Factors Affecting Drug Response: Overview
2.0K
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

01:28Factors Influencing Drug Absorption: Pharmaceutical Parameters

Solid dosage forms such as tablets and capsules undergo rigorous manufacturing processes to ensure stability and effectiveness. Their dissolution and absorption properties are influenced significantly by the choice of excipients (inactive ingredients that serve various roles in the formulation), and the methodology applied during production. The manufacturing parameters, such as compression force and granulation techniques, significantly affect dissolution rates. Elevated compression forces...
