It is considered a safe choice to prevent pregnancy than abortion which is considered life threating. The aim of this study was to assess knowledge, attitude, and practices (KAP) of community pharmacists towards emergency contraceptives and their association with sociodemographic variables. This study was a cross sectional study conducted between August and September 2021 on a convenient sample of community pharmacists from Iraq. The survey tool was an online, self-administered questionnaire, in English language and a paper-based copy of the questionnaire was delivered face-to-face to some of the study participants. The questionnaire consisted of four parts, sociodemographic characteristics, knowledge, attitude and practices of community pharmacists toward emergency contraceptives.  A total of 212 community pharmacists participated in the study. Of the study participants, 67.9% were in the age range of (24-29) years, 61.8% were females,60% had less than 5 years of experience, the majority (73.1%) were from Baghdad. This study showed that the majority of community pharmacists (74%) had good knowledge and 95% of them had a very positive attitude. However, 51% of the participants had poor practice where 62.5% of the pharmacists did not make counselling during dispending on mechanism of action. This study results have shown no significant relationship between demographic characteristics and KAP of participants towards emergency contraceptives. The majority of the study participants had good knowledge and very positive attitude too, whereas poor practice was observed in more than half of the participants. Educational programs and training sessions are required to raise knowledge about the importance of emergency contraceptives and also to improve the dispensing practice of these products.\u0000 ","PeriodicalId":14509,"journal":{"name":"Iraqi Journal of Pharmaceutical Sciences ( P-ISSN: 1683 - 3597 , E-ISSN : 2521 - 3512)","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84479264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over 100 million patients heal with a scar every year. To investigate the role of the beta 2 adrenergic receptor (β2AR); Ritodrine, in wound scarring, the ability of beta 2 adrenergic receptor agonist (β2ARag) to alter HDF differentiation and function, wound inflammation, angiogenesis, and wound scarring was explored in HDFs, zebrafish, chick chorioallantoic membrane assay (CAM), and a porcine skin wound model, respectively. A study identify a β2AR-mediated mechanism for scar reduction. β2ARag significantly reduced HDF differentiation, via multiple cAMP and/or fibroblast growth factor 2 or basic FGF (FGF2)-dependent mechanisms, in the presence of transforming growth factor betaβ1, reduced contractile function, and inhibited mRNA expression of a number of profibrotic markers. β2ARag also reduced inflammation and angiogenesis in zebrafish and CAMs in vivo, respectively. In Red Duroc pig full-thickness wounds, β2ARag reduced both scar area and hyperpigmentation by almost 50% and significantly improved scar quality. Indeed, mechanisms delineated in vitro and in other in vivo models were evident in the β2ARag-treated porcine scars in vivo. Both macrophage infiltration and angiogenesis were initially decreased, whereas DF function was impaired in the β2ARag-treated porcine wound bed. This data reveal the potential of β2ARag to improve skin scarring.\u0000The purpose of this study was to assess the therapeutic effect of topical Ritodrine hydrochloride on hypertrophic scars in rabbits.\u0000Thirty-two healthy male albino rabbits that divided in to 4 groups were included in the study (healthy; induced untreated hypertrophic scars; induced hypertrophic scars treated with 0.1% Triamcinolone acetonide (TAC) as a standard drug; and induced hypertrophic scars treated with 0.5% Ritodrine HCL gel twice daily for 21 days. Histopathology of skin sections, transforming growth factor beta1 TGFβ-1 level, and collagen III alpha1 in skin tissue were all used as outcome measures.\u0000Compared to the induced hypertrophic scar group; treatment with Ritodrine significantly reduced means of TGF β1 and collagen III (p ≤0.01); significantly reduce mean score of inflammation (p ≤0.001), significantly lowered scar size (P ≤ 0.001), and significantly lower mean scar height (P≤0.001), but no significant decrease in SEI (P>0.05).\u0000Therapy of induced hypertrophic scar with topical Ritodrine was successfully effective in rabbits.

One such approach is the deuteration technique: Deuteration is the process of substituting deuterium for hydrogen in a molecule. When compared to the drug molecule, its deuterated analogues may retain the features of the original molecule and, in some cases, improve its pharmacological activity, with fewer side effects and lower toxicity. Metronidazole is a commonly used antibiotic to treat anaerobic bacterial infections, protozoal and microaerophilic bacterial infections. Metronidazole has a half-life of 6.5 ± 2.9 hours. A number of studies have recently been conducted on the selective substitution of hydrogen with deuterium. which increases the bond strength, increasing the biological half-life and, consequently, the drug's metabolic stability also increases. In an attempt to address metronidazole's drawbacks and clinical resistance, deuterated metronidazole was synthesised, characterised, and tested for antibacterial, antifungal, and anti-tubercular activities. The metronidazole and its deuterated compound showed equipotent antifungal activity and aerobic antibacterial activity. Also, when compared with the non-deuterated compound, deuterated metronidazole exhibited better anaerobic antibacterial and anti-tubercular activity.","PeriodicalId":14509,"journal":{"name":"Iraqi Journal of Pharmaceutical Sciences ( P-ISSN: 1683 - 3597 , E-ISSN : 2521 - 3512)","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86332308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate the correlation between genetic polymorphisms in CYP2C19*2 and*3 and recurrent risk in patients with ischemic stroke taking clopidogrel 75mg in Kurdistan region –Iraq. This retrospective case-control study was carried out at Kurdistan, Erbil, Medicina medical center, and Rizgary general hospital from January 2021 to August 2021. The blood sample was taken from the participants and tested for genotyping. The collection of data was taken from patients' medical charts in the hospital and patients’ electronic medical records from the neurology clinic.  Sixty patients participated, (34) were male and (26) were female, with age range (38-96) years, diagnosed from not more than two years with ischemic stroke and taking 75 mg clopidogrel maintenance dose. Genotyping analysis showed 61.7 % were homozygotes for wild allele *1, the heterozygotes divided into 26.7% (*1/*2) and 6.7 % (*1/*3) genotype, while the homozygotes for mutant alleles CYP2C19*2,*3 distributed in 3.3 %(*2/*2) and 1.7 %(*3/*3).

On the other hand, there was no significant relationship between the risk of stroke recurrence and carrying the variant allele CYP2C19 *3 (P = 1.000). Ischemic stroke patients treated with clopidogrel and carrying a CYP2C19*2 allele had a higher risk of recurrent stroke as it is associated with reduced the metabolic activity of CYP2C19 enzyme leading to reduction of clopidogrel effect.","PeriodicalId":14509,"journal":{"name":"Iraqi Journal of Pharmaceutical Sciences ( P-ISSN: 1683 - 3597 , E-ISSN : 2521 - 3512)","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73645863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
