Nevertheless, only 37.6% reported that they would rather take generic medicines than brand medicines.…”

“…The majority of participants (81.8%) reported that they took all the medicines prescribed for them. 52 Figueiras et al 53 conducted a study in Portugal to evaluate the impact of type of disease (influenza, asthma, and angina) on the level of agreement with use of generic medicines. Participants in this study had a relatively positive belief in the efficacy of generic medicines and their similarity to original brand medicines.…”

Background: Generic medicines have the same quality, safety, and efficacy as their counterpart original brand medicines. Generic medicines provide the same therapeutic outcomes but at a much cheaper cost, so are promoted in many countries to contain pharmaceutical expenditure and sustain the health care system. Thus, the perspective of patients and medicine consumers as end users of these medicines is an important factor to enhance the use and utilization of generic medicines. The objective of this paper is to review patients' and consumers' knowledge, perceptions, acceptance, and views of generic medicines in the current literature. Methods: An extensive literature search was performed in several databases, namely Scopus, PubMed, ISI Web of Knowledge, Proquest, and the Wiley online library, to identify relevant studies published in the English literature for the period 1990-2013. Results: A total of 53 studies were included in the review, comprising 24 studies from Europe, ten from North America, six from Asia, five from Australia and New Zealand, five from the Middle East, one from Africa, one from Latin America, and one from the Caribbean region. A large body of literature has reported misconceptions and negative perceptions about generic medicines on the part of patients and medicine consumers. Moreover, although it is reported in almost all countries, the percentage of consumers who had such misconceptions varied from one country to another. However, in many countries, there was a meaningful percentage of patients who had negative perceptions and misconceptions about generic medicines. Moreover, such misconceptions and negative perceptions were reported as major obstacles to the use and acceptance of generic medicines among patients. Further, studies that focused on specific populations (eg, patients with epilepsy, psychosis, or renal disease) reported a more negative perception and more resistance to the use of generic medicines. The type of medical condition and its level of seriousness or severity, recommendations by health care professionals, price difference (ie, cost saving), previous experience of generic medicines, and knowledge/information about generic medicines were considered to be important factors that affect a patient's decision to use a generic medicine or a brand medicine. Conclusion:The results from this literature search show that patients and medicine consumers tend to prefer original brand medicines over generic medicines. Further, in many countries, there is still a considerable proportion of patients and consumers who lack adequate knowledge or have insufficient information about generic medicines. Thus, there is a need for educational interventions and activities to educate patients about generic medicines. It is also evident in the literature that health care professionals (physicians and pharmacists) play a key role in the promotion of generic medicines and in patients' acceptance of generic medicines and generic substitution. Hence, health care professionals need to play a more act...

“…Despite this being the case many treating physicians hardly prescribe generic medicine. [12] Reasons why physicians usually doesn't prescribe generic drugs include Physicians' and sometimes even patients' perception that the cheaper drugs means less effective drugs. [13] Differences in size, shape , colour and name of the drug may lead to patient confusion, this is specially the case where a patient has already been on a drug since many years like antihypertensive or anti diabetic drugs.…”

Background: To study cost-effective and cost-benefit analysis of antibiotic prescription in patients who had enteric fever and was given intravenous ceftriaxone. Methods: This was a prospective observational study conducted in a tertiary care hospital. 200 patients who have been diagnosed with enteric fever and were prescribed ceftriaxone were studied and their prescriptions were analyzed. 5 brands of most commonly prescribed ceftriaxone injections were chosen to analyse costeffective and cost-benefit analysis. Our study showed that there was a major difference of prizes between generic and 5 most commonly prescribed brands of the same drug. Use of branded drugs was associated with increase cost of treatment and in many cases was responsible for failure to take complete treatment as prescribed by treating physician. Results: This Study was conducted on 100 patients, 68 males and 32 females, diagnosed with enteric fever. Out of these patients Maximum number of patients were seen between age group of 30-40 years (34) and minimum patients belonged to age group of more than 60 years (8). Analysis of prescriptions revealed that 80 patients were prescribed Branded drugs and 20% were prescribed generic drugs. Out of these 80 patients who were prescribed branded drugs most common 5 brands were studied. The analysis of the cost of single dose of inj ceftriaxone revealed that branded drugs were 3.12 % to 200.84 % more in comparison with generic IV ceftriaxone. Analysis of cost of 1 day of treatment with IV ceftriaxone 1gm revealed similar figures. Total cost of treatment was Rs 595 for generic drug and 1790 for branded drug with maximum MRP. The Analysis of patients who discountinued treatment before completion revealed that most of them belonged to Brand E (30%) and minimum number of patients belonged to Generic group (5%.Conclusion: The cost of most commonly prescribed branded drugs was significantly higher (3%-200%) than generic drug and prescribing branded drugs was associated with failure to take complete treatment as prescribed by treating physician.

ABSTRACT:-ObjectiveThe aim is to review the actual knowledge and perception of generic medicines in Spain to see if more training and information for the patients is necessary. Method Self-administered questionnaires were used to survey the patient's knowledge and perceptions of generic medicines. The questionnaires were built with an expert panel. The pilot was conducted in Saragossa province (Spain). Results Patients with a low educational level and those older than 51 years had a worse attitude to generics regarding their equivalence, quality and efficacy. Also showed the general non-acceptance of the substitution policy switching from branded to generic medicines. Conclusions More educational actions and campaigns directed to patients were shown to be necessary in order to improve the knowledge of generic drugs, specially focused on groups with negative perceptions. Practice implications Educational activities, direct and individual about security and efficacy of generic medicines increase its acceptance and appreciation. Health professionals (doctors, pharmacists and nurses) are the ones in the best position to develop this educational work. There is a need of a bigger effort in the country on generics information, especially in the group of older than 50 years old and in the lower education group.
