Background: The burden of drug abuse is becoming a public health concern in Nigeria. Preventive measures should include identifying the root causes of the burden for targeted intervention. We, therefore, aim to conduct a scoping review of the literature to summarize the findings of epidemiological studies on drug abuse and provisions of drug laws in Nigeria. The review also provides appropriate recommendations as interventions for prevention.Methods: We conducted a systematic search of the literature on PubMed to identify information on drug abuse and drug laws in Nigeria from the inception of the database to March 2020. Additional information was retrieved from Google Scholar, a manual search of included articles, discussion with experts on the subject matter, and gray literature. Study selection was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statements. Information from gray literature was assessed for quality and accuracy using the AACODS checklist (authority, accuracy, coverage, objectively, date, significance).Results: The systematic search of the literature generated 253 studies. Nine articles were obtained from other sources. After the selection process, 23 eligible studies were included for review. A prevalence of 20–40% and 20.9% of drug abuse was reported among students and youths, respectively. Commonly abused drugs include cannabis, cocaine, amphetamine, heroin, diazepam, codeine, cough syrup and tramadol. Sources where abusers obtained drugs, were pharmacies/patent medicine shops, open drug markets, drug hawkers, fellow drug abusers, friends, and drug pushers. Drug abuse was common among undergraduates and secondary school students, youths, commercial bus drivers, farmers, and sex workers. Reason for use included to increase physical performance, stress and to derive pleasure. Poor socioeconomic factors and low educational background were the common risk factors associated with drug abuse. We identified several drug laws and policies that were established under government agencies such as the National Drug Law Enforcement Agency (NDLEA), National Agency for Foods and Drugs Administration and Control (NAFDAC), Pharmacists Council of Nigeria (PCN) and a Presidential Advisory Committee.Conclusion: Findings from epidemiological studies on drug abuse in Nigeria has demonstrated that the burden of drug abuse is still high despite the existing drug laws, policies, and strategies for prevention. Measures to reduce the burden should involve the community, government, and religious bodies. Preventive measures should target the youths, the students, identified sources of the drugs, reasons and risk factors associated with drug abuse in Nigeria.

Abstract:: The recent increased interest in orodispersible films (ODF) stems from their ideal potential to circumvents several pharmacotherapy related problems, such as improved medication compliance and adherence especially in children, elderly and uncooperative patients. Their administration is well accepted by the majority of patients because ODF dissolve upon in contact with the saliva in the oral cavity without need of water intake. ODF application in personalized pharmacotherapy is currently being exploited. Moreover, innovative preparation methods and characterization technologies have been evolving in recent years, highlighting promising future both from the technological and clinical standpoints. However, the key obstacles to the attainment of full potentials of ODF in the pharmaceutical field is the lack of harmonized and well-defined quality characterization procedures, standard evaluation parameters, guidance on appropriate final product properties and specifications. This review provides an appraisal on the ODF characterization methods from slurries to the finished medicinal products with a specific focus on the technologies suitable for identification, quantification, and quality evaluation of extemporaneously prepared ODF on small batches in individualized pharmacotherapy. Generally, there is a paradigm shift from the use of the conventional quality evaluation tools and/or protocols for oral solid dosage forms to characterize ODF to more specific equipment and procedures that suit the peculiarities of the ODF.
