Practice of Perioperative Rational Use of Antibacterial Drugs Based on Drug Pathway

[Objectives]To establish a new management model for rational use of perioperative antibacterial drugs in surgical departments.[Methods]Based on evidence-based medicine,the department s drug pathway was formulated,and the new mode of rational drug use control was established by using fine pharmaceutical technology intervention,and the intervention effect was evaluated by the intensity of antibacterial drug use,per capita drug costs and the proportion of drugs.[Results]After adopting drug pathway in departments,the intensity of antibacterial drug use,per capita drug costs and the proportion of drugs decreased significantly,and the effect of rational drug use control was remarkable.[Conclusions]The drug pathway provides a new management and control mode for the rational use of perioperative antibacterial drugs in surgical departments of hospitals.Thus,it is worthy of popularization and application.

The Level of Knowledge, Behaviors, and Attitudes on Rational Use of Drugs of Patients Who Applied to the Family Health Center in Istanbul, Türkiye: A Cross-Sectional Study

Background: This study, it was aimed to determine the level of knowledge, attitudes, and behaviors of patients who applied to a family health center about the rational use of drugs. Irrational use of drugs is a major problem worldwide. WHO reports that half of the patients do not use their drugs correctly. Methods: This cross-sectional study was conducted between 1 October 2017 and 30 November 2018 at Istanbul Fatih Family Health Center No 7. The sample size was determined as 301 people selected by systematic sampling method from patients aged 18 and older. Results: The mean age of the participants was 53.8% ± 16.8%, 59.8% were female, 62.5% were married, and 52.5% were primary school graduates. 63.9% of the participants knew the names of the drugs they used, and 79.9% of them knew the indication for use. 89% of individuals check the expiry date of the drugs before using them, and 83.1% read the drug prospectus. 84% of the participants support the prohibition of using over-the-counter drugs. Conclusion: The level of knowledge of the participants about the rational use of drugs is above the societal average. However, some issues need more awareness. The high level of rational use of drugs awareness of physicians and pharmacists will also strengthen the rational use of drugs and indirectly increase the awareness of the public.

Clinical Analysis of Common Irrational Gastroenterology Medication Problems in The Gastroenterology Department

Objective: To investigate and analyze the irrational problems of common gastroenterology medications applied to gastroenterology patients during treatment, and to develop and implement countermeasures. Methods: This study included 60 patients admitted to the Department of Gastroenterology from January 2021 to December 2023 who were randomly divided into a control group (conventional drug management) and an observation group (targeted drug treatment), of 30 cases each. After the implementation of different management methods, the occurrence of irrational drug use and the incidence of adverse reactions between both groups were compared and statistically analyzed. Results: The incidence of irrational medication in the observation group (13.33%) was lower than that in the control group (40.00%) (P < 0.05). The occurrence of adverse reactions in the observation group (10.00%) was lower than that of the control group (36.67%) after treatment (P < 0.05). The observation group had a higher level of satisfaction after treatment (90.00%) as compared to the control group (66.67%) (P < 0.05). Conclusion: Implementation of targeted drug treatment for gastroenterology patients reduced the incidence of irrational medication use, reduced adverse reactions, and improved patient satisfaction.

Present situation of rational drug use in plateau area

Plateau is characterized by low oxygen,low pressure,strong radiation,cold and dryness,among which low oxygen is the main factor that affects the normal life activities of human body.Altitude hypoxia leads to significant changes in the metabolic characteristics of drugs in vivo,which in turn affects the efficacy and adverse actions of drugs.This paper summarizes the present situation of rational drug use in plateau area and pinpoints the existing problems.Meanwhile,we posit the strategies and measures for realizing rational and precise pharmacotherapy of plateau residents.First,we need to acquire a panoramic view of differential and relative pharmacokinetics and pharmacodynamics in between plateau area and plain area by carrying out comparative studies on drug metabolisms and on comprehensive drug efficacies and mechanisms.Second,we must apply the findings from basic research to clinical practice and formulate guidelines and recommendations of drug use for plateau habitants.Finally,we should eventually achieve precise and individualized drug use for plateau habitants based on their characteristic etiology and pathogenesis.

I Just Trust Him: The Notion of Consideration as a Barrier to Condom Use amongst Women Who Inject Drugs in Central Java

The HIV epidemic in Indonesia has risen sharply since 2004, from 2682 cases in 2004 to 19,973 in 2009. The main transmission route of HIV in Indonesia is injecting drug use. There is little research on women who inject drugs in Indonesia. In-depth interviews were carried out with 19 women who injected drugs in three small cities in central Java. The interviews explored the living conditions of the women and the context of HIV risk. The transcripts were coded and the data were thematically analyzed. In this paper we report on condom use with regular partners. Condom use was very low with their regular partners, even though both they and their partners were injecting drug users. The reasons women gave were that they trusted their partners (although they realised this trust was shaky). The women used traditional Javanese cultural concepts of consideration to explain why they did not use condoms. This was heightened by other cultural norms of women’s place in Javanese society. Although the women in the study were marginalized because of their drug use, they still hold to many Indonesian cultural precepts—of consideration and care for the other above oneself in their relationships with their regular partners which impede condom use. While notions of consideration and harmony were used to explain non-condom use, the same notions could also be used in couple-counseling to assist.

Comparative Review of Drugs Used in Diabetes Mellitus—New and Old

Background: Diabetes mellitus (DM) is a syndrome of chronically elevated glucose level in the blood either due to insulin resistance, insulin deficiency or both. In addition, it may occur due to defective metabolism of carbohydrates, fats and proteins. There are 3 main types of DM: Type 2 DM is more prevalent in adults and is typically due to relative insulin deficiency, deficiency of insulin in children leads to DM type 1;and lastly, gestational diabetes occurs during pregnancy resulting from an imbalance of placental hormones. Introduction: Insulin, Biguanides and Sulfonylureas are some of the drug classes used to treat DM. However, their use is complicated by numerous side effects, such as;hypoglycemia & weight gain from insulin and sulfonylureas;lactic acidosis, vitamin B12 deficiency and gastrointestinal upset with metformin. Route of administration and cost are also important factors to consider when prescribing. It is for this reason the quest for newer, safer and easier to administer drugs is ongoing. Methodology: Used all the articles available on anti Diabetic drugs on web especially in British Medical Journal, Elsevier, Pubmed, Google scholar and Wikipedia etc. Got a final review article to compare the older and newer anti Diabetic drugs. Results and Conclusion: Insulin is good for controlling acute hyperglycemic states in DM but it causes acute hypoglycemia and lipodystrophy. Metformin is good hypoglycemic and easily available but causes hypoglycemia, metallic taste, Lactic acidosis and B12 deficiency. Sulfonylureas are good hypoglycemic but causes severe hypoglycemia acutely and weight gain so contraindicated for obese or hypertensive patients. While newer antidiabetics such as GLP 1 agonists increases insulin secretions has very low risk of hypoglycemia, causes weight loss as compared to insulin and decreases risk of cardiovascular side effects but still can’t be used in renally impaired patients, causes pancreatitis and can not be given in gastroparesis patients, similarly a newer drug of this class known as LY2189265 has long halflife of 90 hours, better efficacy, but causes pancreatitis and increase diastolic BP in high doses, pancreatitis is not associated with lixisenatide (GLP 1 agonist), while DPP4 inhibitors which increases GLP 1 in body has less risk of hypoglycemia, GI side effects, are weight neutral can be used in CKD but causes headaches and Nasopharyngitis. Bromocriptine or pegvisomant are used in patients of growth hormones adenoma induced DM as a medical therapy but are associated with psychosis and hallucinations. Meglitinides increases insulin secretion and has minuscule risk of hypoglycemia but can not be used in CKD patients. Otelixizumab and Teplizumab decrease T cell functions and save beta cells from immune reactions used in DM 1 but cause immune suppression and is an orphan drug. Recombinant GAD used in vaccines decreased antibody mediated beta cell damage but is still under studies.

The role of drug utilization evaluation in medical sciences

Background:Drug utilization evaluation(DUE)is defined by the World Health Organization(WHO)and focuses on the medical,social,and economic consequences of pharmaceutical marketing,distribution,prescribing,and usage in society.The WHO recommends a physician to every 1000 people.According to the recent data from the Health Ministry in 2019,in which 1.16 million doctors are of active population with just 80%,or 0.9 million,practicing.As a result,a ratio of 0.68 doctors for every 1000 people,which is much below as per the WHO reports.This article describes history,types,WHO guidelines,need and purpose of DUE.Objective:The main aim of this paper is to provide information about the rational use of medication in outpa­tient and inpatient department with special emphasis of DUEs.It also provides awareness directly to healthcare professionals,researchers,academicians,pharmacist and nurses to reduce the irrationality of medicines.Methods:The method used to compile this review information gathered from websites,Google scholar,PubMed,Research gate,and studies published on DUE from July 20 to Oct 22 were included as source of information.Results:We studied more than 35 published study on DUE,that reveals most of the physicians prescribed branded drugs not generic drugs,but WHO prescribing indicator allows to prescribe generic drugs in the hospital pharmacy to maintain better inventory control.It may also help to prevent pharmacist misunderstanding during dispensing.Conclusion:The use of generic prescription names avoids the possibility of medication product duplication and lowers patient costs.It is important to remember that incorrect medication prescriptions have impact on both patients and their family members.WHO indicators identify irrational prescribing behaviours to make therapy more rational and cost-effective.

Evaluation of Perinatal and Developmental Outcomes in Neonates with Abstinence Syndrome Admitted to NICU

Drug abuse by pregnant women is one of the significant problems for mothers and their neonates.This study aimed to investigate the effects of maternal substance use disorder during pregnancy on neonatal developmental criteria.In a case-control study,clinical records of 90 neonates diagnosed with neonatal abstinence syndrome who were admitted to NICU in one of four hospitals affiliated with Shahid-Beheshti University of Medical Sciences in Tehran,Iran between 2017 and 2020 were compared to 90 neonates without neonatal abstinence syndrome(control group).Demographic information and data for neonatal developmental characteristics and complications were extracted from the clinical records of this convenience sample.Data for the type and method of maternal substance use during pregnancy were collected through a telephone call with mothers.Our data showed that the prevalence of drug addiction was 1.8%among pregnant women,and the most common drugs used by mothers were opium(n=45%,50%),amphetamine(n=30%,33%),and methadone(n=14%,16%).Neonates with abstinence syndrome had a higher prevalence of transient tachypnea of the newborn(TTN)(P=0.004),and a prevalence of being admitted to NICU(P=0.05)and for a longer duration(P<0.001).Their mothers had a higher prevalence of having pre-eclampsia(P=0.010).Using morphine vs.amphetamine showed no difference based on their effects on mothers and neonates.Substance use during pregnancy increased the prevalence of pregnancy complications(pre-eclampsia)and neonatal complications(TTN and prevalence and duration of hospitalization).Therefore,planning for the development of health policies to raise awareness among women and more broadly,all members of the community,is important to prevent the tendency to engage in this potentially high-risk behavior.

Study on the Effect of Shuanghuanglian Powder Needle Combined with Cefoperazone and Sulbactam Sodium on Pseudomonas aeruginosa in Vitro

Objective: To explore the antibacterial activity of combined use of Shuanghuanglian and cefoperazone sulbactam sodium on resistant strains of Pseudomonas aeruginosa. Methods: The Pseudomonas aeruginosa strains which were sensitive and resistant to cefoperazone sulbactam sodium were selected to prepare different test bacterial solutions respectively;The experimental liquid of Shuanghuanglian and Cefoperazone Sulbactam Sodium were prepared separately and set as different test groups and control groups;The Drug Sensitivity Tests of Shuanghuanglian and cefoperazone sulbactam sodium at different concentration gradients which were used alone or used in combination were carried out for different strains with sensitivity and resistance, And use standard entry as a reference control. Result: The results of drug sensitivity test of Shuanghuanglian combined with Cefoperazone-Sulbactam sodium against the resistant strains of Pseudomonas aeruginosa were compared with the results of drug sensitivity test of the two separately used, and the difference was statistically significant (P 〈 0.05) [The drug sensitivity test results of Shuanghuanglian and cefoperazone sulbactam sodium to Pseudomonas aeruginosa resistant strains were statistically significant compared with the drug sensitivity test results of Shuanghuanglian and Cefoperazone Sulbactam Sodium used separately (P 〈 0.05)];There was a dependence between strains and concentration in the effect of the combination of the two drugs. Conclusion: The combination of Shuanghuanglian and cefoperazone sulbactam sodium has synergistic antibacterial or bactericidal effect on Pseudomonas aeruginosa resistant strains. .

Association between Maternal Drug Use and Cytochrome P450 Genetic Polymorphisms and the Risk of Congenital Heart Defects in Offspring

Objective This study aimed to assess the associations between maternal drug use,cytochrome P450(CYP450)genetic polymorphisms,and their interactions with the risk of congenital heart defects(CHDs)in offspring.Methods A case-control study involving 569 mothers of CHD cases and 652 controls was conducted from November 2017 to January 2020.Results After adjusting for potential confounding factors,the results show that mothers who used ovulatory drugs(adjusted odds ratio[a OR]=2.12;95% confidence interval[CI]:1.08-4.16),antidepressants(a OR=2.56;95%CI:1.36-4.82),antiabortifacients(a OR=1.55;95%CI:1.00-2.40),or traditional Chinese drugs(a OR=1.97;95%CI:1.26-3.09)during pregnancy were at a significantly higher risk of CHDs in offspring.Maternal CYP450 genetic polymorphisms at rs1065852(A/T vs.A/A:OR=1.53,95%CI:1.10-2.14;T/T vs.A/A:OR=1.57,95%CI:1.07-2.31)and rs16947(G/G vs.C/C:OR=3.41,95%CI:1.82-6.39)were also significantly associated with the risk of CHDs in offspring.Additionally,significant interactions were observed between the CYP450 genetic variants and drug use on the development of CHDs.Conclusions In those of Chinese descent,ovulatory drugs,antidepressants,antiabortifacients,and traditional Chinese medicines may be associated with the risk of CHDs in offspring.Maternal CYP450 genes may regulate the effects of maternal drug exposure on fetal heart development.

A mimic of soft tissue infection: intra-arterial injection drug use producing hand swelling and digital ischemia

BACKGROUND: Inadvertent intra-arterial injection of illicit substances is a known complication of injection drug use and can lead to severe complications, including infection, ischemia and compartment syndrome. Identifying complications of intra-arterial injection can be difficult, as clinical manifestations overlap with other more common conditions such as cellulitis and soft tissue infection, and a history of injection drug use is frequently not disclosed.METHODS: A 37-year-old male patient presented with 24 hours of right hand pain, erythema and swelling. Despite classic "track marks", he denied a history of injection drug use, and vascular insults were not initially considered. After failing to respond to three days of aggressive treatment for suspected deep-space infection, an arteriogram demonstrated findings consistent with digital ischemia of embolic etiology.RESULTS: As a result of the delay in diagnosis, the lesion was not amenable to reperfusion and the patient required amputation of the distal digit.CONCLUSION: Practitioners should be alert to the possibility of intra-arterial injection and resulting complications when evaluating unusual extremity infections or unexplained ischemic symptoms, even in the absence of a definite history of injection drug use.

Problem-Based Learning of Drug Use and Abuse during COVID-19 Contingency

Introduction: Nursing students’ experiences during the pandemic provoked social isolation, the way to learn and every context increasing their stress and anxiety leading to drug use and abuse, among others. Problem-based learning (PBL) is a pedagogic strategy to strengthen significant learning;then the objective was to establish PBL influence in nursing students’ experiences on drug use and abuse during COVID-19 contingency. Methods: Qualitative, phenomenological and descriptive paradigm, 12 female and male nursing students aged 20 - 24 years old from the 5th and 6th semesters participated. Information collection was through semi-structured interview and a deep one in four cases. A guide of questions about: How the pandemic impacted your life? How did you face it? And what did you learn during this process? Those questions were used. Qualitative data analysis was based on De Souza Minayo, and signed informed consent was obtained from participants. Results: Students’ experiences allowed four categories to emerge, with six sub-categories. Category I. Students’ experiences on drug use and abuse facing the sanitary contingency;Category II. Students’ skills development to identify a problem and design of appropriate solutions;Category III. Developing skills to favor interpersonal relationships;Category IV. Influence of PBL in nursing students’ experiences on drug use and abuse during the COVID-19 contingency. Conclusion: PBL favored analysis and thoughts in nursing students’ experiences on drug use and abuse during the COVID-19 contingency, they worked collaboratively, developed resilience to daily life situations, and implemented stress coping strategies with their significant learning, which diminished their risk behavior.

Prescription pattern of anti-malarial drugs in a tertiary care hospital

Objective:To evaluate the prescribing pattern of anti malarial drugs in a tertiary care hospital. Methods:A prospective cross-sectional study was conducted for 6 months of patients visiting in Basaveshwar Teaching and General Hospital,Gulbarga.Data were analyzed for various drug use indicators.Results:A total of 212 prescriptions were collected,with 136(64.15%) male and 76(35.85%) female.There were 128(60.37%) Plasmodium vivax cases and 84(39.63%) Plasmodium falciparum cases.All Plasmodium vivax cases were treated with chloroquine alone and among these 16(12.5%) recieved radical treatment with primaquine along with chloroquine.Among 84 patients with Pasmodium falciparum,40 patients received single drug such as quinine/ mefloquinine/artesunate/arteether.Another 44 patients received multidrug regime like,quinine+artesunate(54.54%),quinine+mefloquine(27.27%) and quinine+arteether (18.18%).Chloroquine was not administered to any of the patients with Plasmodium falciparum malaria.The most common adverse effects with chloroquine were anorexia,nausea,vomiting and tinnitus in 9.37% of the cases.With quinine it was nausea and vomiting in 17.64% ,tinnitus in 11.76% and hypoglycemia in 2.1% of cases.Conclusions:Our study found the perennial favorites like chloroquine for Plasmodium vivax and quinine for Plasmodium falciparum were the most effective drug.In the severe Plasmodium falciparum cases the artesunate derivatives and combination of artesunate with quinine/mefloquine were most effective with fewer incidences of side effects.

COMBINED TREATMENT OF HEBETIC SCANTY MENSTRUATION WITH ACUPUNCTURE AND DRUGS

According to a random distribution table, 60 cases of scanty menstruation patients were evenly divided into 3 groups: A) estrin (n = 20), B) acupuncture (n = 20), and C) acupuncture +estrin (n = 20) for comparing their therapeutic effect. Results showed that after treatment, 5 cases in estrin group, 12 cases in acupuncture group and 14 cases in acupuncture + estrin group respectively had an ovulation response. Statistical analysis displayed significant differences between acupuncture group or acupuncture + estrin group and estrin group. (P < 0.05, P <0.05 ); and between acupuneture and acupuncture + estrin groups in the estradiol level of the early phase of follicles in patients with ovulation and without ovulation (P < 0. 05, P < 0.01 ). The fact indicates a close interrelation between acupuncture-induced ovulatory effect and the estradiol level of the patient’s body.

Prevalence of substance use among moroccan adolescents and association with academic achievement

AIM: To investigate rates of drug and alcohol use and their association with academic performance in Moroccan youth. METHODS: An adapted version of the European School Project on Alcohol and Other Drugs survey was administered to 2139 10^(th)-12^(th) graders in 36 Moroccan public high schools. Two multiple logistic regressions were completed, one for male and one for female subjects. Grade average was used as a two-part outcome variable, and drug use was used as a four-level categorical independent variable. Parents' education levels and socioeconomic status were included as covariates. RESULTS: Of the subjects, 181 girls(16%) and 390 boys(40%) reported ever having used alcohol, hashish, or psychotropic drugs. Girls who had used any of those substances in the past 30 d demonstrated an adjusted odds ratio(AOR) of 2.62(95%CI: 1.31-5.22) of having average or below-average grades, and those with any lifetime use showed an AOR of 1.72(95%CI: 1.07-2.77). Among the boys, use in the past 30 d was associated with an AOR of 2.08(95%CI: 1.33-3.24) of average or below average grades, and use in the last 12 mo with an AOR of 1.74(95%CI: 1.00-3.05). Any lifetime use among male and previous 12 mo use among female subjects were not significantly associated with academic achievement.CONCLUSION: Among Moroccan adolescents, drug use is substantially different between boys and girls. In both genders, lower academic achievement was associated with alcohol, hashish, or psychotropic drug use in the last 30 d.

Prevalence of Human Immunodeficiency Virus (HIV), Risk Behavior, and Recent Substance Use in a Sample of Urban Drug Users: Findings by Race and Sex

The aim of the current study was to examine the prevalence of HIV, past six-month illicit drug use, and risk behaviors among a population of heavy drug users living in an urban setting. Although many studies investigate substance use, sex-risk behavior, and HIV by race and gender, no studies have examined these variables simultaneously. The current study seeks to fill this gap in the literature by exploring HIV prevalence among a predominantly heterosexual sample of recent substance users by injection drug use (IDU) status, race, and sex. Baseline data from the Baltimore site of the NEURO-HIV epidemiologic study was used in this study. This study examines neuropsychological and social-behavioral risk factors of HIV, hepatitis A, hepatitis B, and hepatitis C among both injection and non-injection drug users. Descriptive statistics and chi-square statistics were used in data analyses. Blood and urine samples were obtained to test for the presence of recent drug use, viral hepatitis, HIV, and other sexually transmitted diseases (STDs). Findings presented here have several important implications for HIV prevention and care among substance users. Intervention programs that incorporate substance use treatment in addition to HIV education, particularly with respect to substance use and sex risk behavior are imperative.

Mixture Models for Estimating the Number of Drug Users in Thailand 2005-2007

It is difficult to measure the sizes of illegal drug user populations directly by using the survey method because of many “hidden drug addicts” and the difficulty of receiving a true response. Systematic and routine information on treatment episodes of drug users is adopted to estimate the population size in this study. Mixture models of zero-truncated Poisson distributions using the nonparametric maximum likelihood estimators (NPMLE) by means of capture-recapture repeated count data were used to project the number of drug users. The method was applied to surveillance data of drug users identified by treatment episodes in over 1140 health treatment centers in Thailand from the Bureau of Health Service System Development, Ministry of Public Health. We presented how this mixture model could be utilized to construct the unobserved frequency of drug users with no treatment episode and further estimated the total population size of drug users in the country from 2005 to 2007. The result of simulation was confirmed that mixture model is suitable when population is large. By means of mixture models, the estimations for the number of drug users were fitted with excellent goodness-of-fit values and we were also compared to the conventional Chao estimates. The NPMLE for the total number of drug users in Thailand 2005, 2006, and 2007 were 184,045 (95% CI: 181,297-86,793), 230,665 (95% CI: 226,611-234,719), 299,670 (95% CI: 294,217-305,123), respectively, also 125,265 (95% CI: 123,092-127,142), 166,287 (95% CI: 163,222-169,352), 228,898 (95% CI: 224,766 - 233,030) for the number of methamphetamine (Yaba) users, and 11,559 (95% CI: 10,234-12,884), 11,333 (95% CI: 9276-13,390), 8953 (95% CI: 7878-10,028) for the number of heroin users, respectively. The numbers of marijuana, kratom-plant, opium, and inhalant users were underestimated because their symptoms were mild and not severe enough to remedy in health treatment centers which led to the smaller size of the total number of drug users. The well-estimated sizes of heroin and methamphetamine addicts are high reliable because they are based on clearly evident count with a severe addiction problem to health treatment centers. The estimation by means of mixture models can be recommended to monitor drug demand trend and drug health service routinely;it is easy to calculate via the available programs MIXTP based on request.

Analysis and Dynamics of Illicit Drug Use Described by Fractional Derivative with Mittag-Leffler Kernel

Illicit drug use is a significant problem that causes great material and moral losses and threatens the future of the society.For this reason,illicit drug use and related crimes are the most significant criminal cases examined by scientists.This paper aims at modeling the illegal drug use using the Atangana-Baleanu fractional derivative with Mittag-Leffler kernel.Also,in this work,the existence and uniqueness of solutions of the fractional-order Illicit drug use model are discussed via Picard-Lindelöf theorem which provides successive approximations using a convergent sequence.Then the stability analysis for both disease-free and endemic equilibrium states is conducted.A numerical scheme based on the known Adams-Bashforth method is designed in fractional form to approximate the novel Atangana-Baleanu fractional operator of order 0<a≤1.Finally,numerical simulation results based on different values of fractional order,which also serve as control parameter,are presented to justify the theoretical findings.

Analysis on the Problems of Rational Drug Use Carrying Out by Hospital Pharmacists in China

Pharmacists are the implementers of clinical drug management, and they play an irreplaceable role in promoting the improvement of rational drug use. However, the current role of pharmacists in the supervision and protection of rational drug use has not been fully exerted. This article is aimed to investigate the current situation of pharmacists’ work of rational drug use from the perspectives of pharmacists, physicians, and patients. It is found that the professional value of pharmacists in the rational drug use has not been valued by medical institutions, physicians, and patients. Pharmacists face problems such as workload, working conditions, and doctor-patient cooperation in the rational drug use. Suggestions are made for further exerting the professional value of pharmacists in promoting the level of rational drug use. Relevant managers should pay full attention to the professional value of pharmacists, and provide corresponding system and facility guarantees for pharmacists to carry out rational drug use.
