With over 115 registered pharmaceutical manufacturers, Nigeria still depends on other countries for the supply of active pharmaceutical ingredients and excipients. Significant attention has not been paid to the local production of raw materials, pharmaceutical dosage formulations, or processing equipment, which has resulted in a decline in the country's pharmaceutical manufacturing capacity. Owing to the overall importance of the pharmaceutical industry, it is, therefore, essential to pay close attention to developmental issues affecting this sector. In this commentary, we explore why Nigeria must boost its local pharmaceutical manufacturing capacity.
Background The incidence of pain and inflammation in West Africa and in fact globally, continues to increase at an alarming rate. This research was conducted to investigate the analgesic and anti-inflammatory activities of leaf extracts of Chasmanthera dependens and Chenopodium ambrosioides ; formulate and evaluate polyherbal gels from their combination in a bid to providing topical therapeutic solutions to pain and inflammation. Methods Pre-formulation studies (phytochemical analysis, in vitro analgesic and anti-inflammatory activities) were conducted on the methanol leaf extracts of Chasmanthera dependens and Chenopodium ambrosioides . Individual and polyherbal gels were prepared using polymer carbopol 940 (1%) at combination ratios of 0:100, 25:75, 50:50, 75:25 and 100:0 Chasmanthera : Chenopodium. These herbal gels were evaluated for physical parameters, pH, viscosity, extrudability and spreadability. Analgesic and anti-inflammatory activities of herbal gels were evaluated by their inhibitory activities (percentage inhibition) against COX-2, TNF-α, IL-10, PGE-2 and compared with commercial diclofenac gel. Results The phytochemicals of the two extracts detected gave varied contents of major classes of secondary metabolites. The pre formulation inhibitory studies of the two extracts exhibited dose dependent inhibitory activities against COX-2, TNF-α, IL-10, PGE-2. The physical appearance, homogeneity, and consistency of the herbal formulations were good. The herbal gels were spreadable with good extrudability. The pH of the herbal gels ranged from 4.5 ± 0.4 to 5.2 ± 0.4. The viscosity of the herbal gels ranged between 4.3 ± 0.2 and 4.7 ± 0.4 Pas. The herbal gels exhibited significant differences in inhibitory activities against COX-2, TNF-α, IL-10, PGE-2 when compared with control commercial diclofenac gel. Conclusion The outcomes, including the inhibition of mediators COX-2, TNF-α, IL-10, PGE-2, confirm the use of the plant extracts under study, the individual and polyherbal gels formulated for the potential topical therapeutic treatment of pain and inflammation.
Background: It is revealing that pharmacy as a key health care profession is almost invisible within more recent health policy initiatives in Nigeria. This research is an effort to improve awareness about the pharmacy profession. The target shall be young, science inclined individuals in high schools; they are the future. Objective: To assess the levels of knowledge of high school science students about pharmacy and their interest in becoming pharmacists before and after sessions of awareness and education about the profession. Method: The study was a behavioral intervention study with pre and post cross-sectional survey; carried out in three high schools across Lagos, Nigeria; 127 science students participated. Information was collected using questionnaires inquiring into the career interests of the students and their levels of awareness of the pharmacy profession before and after series of coordinated sensitization about pharmacy. There was one sensitization exercise conducted per school and each lasted for about 80 min with breaks in between. An average of 40 students per school (all science majors present on the day of the survey) participated in the study. A pretest was first conducted, followed by the campaign and then a posttest to assess impact. Communication was done in English language all through the survey. Results: and Discussion: Most of the students claimed to know who a pharmacist is. However, upon further probe, only 3.1 percent of the respondents had a very good knowledge of what the pharmacy profession entails, from the pretest. At the end of the awareness discussions, an appreciable 18.1 percent of the students now had very good knowledge of the pharmacy profession. Similarly, a better 11.8 percent of students became interested in becoming pharmacists against the previously recorded 5.5 percent. This depicts how strategic advocacies can be utilized in building good professionals and ensuring a sustainable legacy for pharmacy in Nigeria. Conclusion:The study establishes that the knowledge and awareness of high school science students about the pharmacy profession is relatively low across three selected secondary schools. The sensitization held yielded measurable improvement in awareness and interest. In view of this, Pharmacists in Nigeria are implored to do more of career mentorship.
Purpose Parquetina nigrescens (Pn) extract was evaluated for safety and antidiarrheal activity, formulated into stable suspensions, and characterized. Methods Acute toxicity of the extract based on Organization for Economic Cooperation and Development-423 guidelines was performed. The antidiarrheal effects of the extract on castor oil-induced diarrhea in four groups of Wistar rats were determined. The first and second groups received 5 and 200 mg/kg body weight (bw) of the extract, while the third and fourth groups received normal saline (5 mg/kg bw) and loperamide (5 mg/kg bw) as negative and positive controls, respectively. Pn extract was used at 1.25% w/v to formulate structured vehicle (carboxylmethylcellulose, polyvinylpyrrolidone and tragacanth) suspensions. The suspensions were tested for pharmacological activity and characterized. Results Acute toxicity gave a lethal dose 50 (LD50) that is greater than 300 and less than 2,000 mg/kg bw. A reduction in intestinal transit by 0.14 and 0.15% at 5 and 200 mg/kg of the extract was achieved as compared to an inhibition of 0.12% by 5 mg/kg loperamide. There was a dose-dependent decrease in the frequency of watery stool passed in castor oil-induced rats by 35.29% and 64.70% at 5 and 200 mg/kg, respectively. All the suspensions inhibited diarrhea, exhibiting a dose-dependent pattern and remained stable after 4 weeks. Their pH values ranged from 4.60±2.73 to 4.73±1.91, while viscosity ranged from 3.50±1.23 to 6.75±1.24 Pas at 60 rpm. Conclusion The results suggest that Pn possesses significant antidiarrheal activity. Suspensions of Pn were successfully formulated in structured vehicles and were effective in the control of diarrhea in Wistar rats.
