In Islam, prohibitions are specified either by a verse of the Quran or an authentic and explicit Sunnah of Muhammad, peace be upon him (PBUH). These rules of Shariah (i.e., Islamic law) give Muslims the freedom to eat and drink anything they like as long as it is not Haram (prohibited).

cleanaccordingtoShariahlaw. Muslims who are directly engaged inmanufacturing, distributing, dispensing, andprescribing medications are responsible forensuringthatpharmaceuticalproductsareHalalandTayyib(5).This isanextremelychallengingtask in foodproduction. It ispossible thatsomepeople believe that medicines are vital andthat Haram substances may be used in certaincircumstances as they were permitted andtolerated in Islam. The lack of awareness andknowledgeofHalalstatusofmedicationsamongMuslim consumers and patients could be therootof thiscomplex issuerelatedtotheconceptof Halal-Tayyib pharmaceuticals. Therefore,in-depth study and search forHalal and Tayyibpharmaceuticalsisnotonlytheresponsiblityofanindividual(fardhu ain)butalsotheresponsibilityof the experts and the community (fardhu kifayah). Thesedays,increasedattentionisgiventotheHalal status of the food thatMuslims consume.ThisisanimportantpartofIslamicpracticesandfaith.Similarly,Muslimconsumersandpatientsare showing a growing interest in referencesconcerning the Halal status of pharmaceuticals(6). Therefore, this study was undertaken inorder to explore the Halal status of commonlyused cardiovascular, respiratory, and endocrinecategories of medications. The Halal statuswas determined for both the active ingredientsand excipients contained in the dosage form ofproductsthatwereassessed.

Materials and Methods

A descriptive and exploratory study wasconductedfromSeptember2009toMarch2010atagovernmenthospitalintheNorthernpartoftheMalaysianPeninsula.Pharmaceuticalproductsin the categories of cardiovascular, respiratory,and endocrine medications that were availableat the out-patient pharmacy at the time of thisstudy were selected. Patients were not involvedin the study as all datawere collected from theevaluationsofpharmaceuticaldosageforms.Theavailable product leaflets were sorted to list alltheactiveingredientsandexcipients.Theofficialwebsite of Medication Index for Malaysia andSingapore(MIMS)wasreferredtoforadditionalinformation. The product’s manufacturer wascontacted if the necessary information was notfoundintheproduct’spackageinsertandwasnotstatedinMIMS. The Halal status was categorized as Halal,MushboohorHaram.Thiswasprimarilybasedon

informationregardingthesourcesoftheproduct’sactiveingredientsandexcipients.Similartofoodproducts,thesourcesofalltheingredients—bothactive ingredients and excipients—used in theformulationofaparticulardosageformmustbeaHalal substance. The Halal status of all theingredientsusedintheformulationofaparticulardosage form was based on whether it is fromanimal source or whether it contains alcohol.Otheraspectssuchaspotentialharmfulnessandhygiene of the preparation processes were nottakenintoconsideration. Ethical approval was not required butpermissionwasgrantedbythehospitalauthorityfor data collection from the product packageinserts. The data were computed and analysedusing Statistical Package for the Social Sciences(SPSS) version 18 and descriptive analysis wasconducted.

Results

Out of 221 pharmaceutical products in thecategories of cardiovascular, respiratory andendocrinemedications,only63weresuitableforassessment of the Halal status. These productscontained a total of 240 active ingredients and570 excipients. Lack of information about theproduct’s constituents was the main factorhindering the identification of the Halal status.Furthermore,majorityofthemanufacturerswerenotcooperativeinprovidingdetailedinformationabouttheirproducts. Injectionsandtabletscomprised49.2%and28.6%, respectively, of the dosage forms. Theassessment of the Halal status for the varioustypes of dosage forms is shown in Table 1.

The Halal status could not be assessed for73outof240activeingredients.Thiswasduetothe difficulty in obtaining accurate informationrelated to theirorigins.ThepercentageofactiveingredientscategorizedasHalal,MushboohandHaramwas83.8%(140),13.2%(22),and3%(5),respectively.ThedistributionofHalal status forthecombinationofcardiovascularandendocrinemedicationsaswellasforrespiratorymedicationsispresentedinFigure3. Out of 570 excipients, 54 could not beevaluated due to lack of information. Thedistribution of Halal, Mushbooh and Haramwas at 70% (361), 27.3% (141), and 2.7% (14),

Discussion

Until recently, there were no specificguidelinesavailableinthelocalcontextforpatientsand healthcare providers in understanding

Halal medications. There are numbers ofwebsites, documents and guidebooks dedicatedfor consumers to describe and explains issuesrelatedtoHalalfoods(7,8).Thisstudy,aimedtofill thegapinliteratureonHalalmedicationsbyhighlightingtheHalalstatusofmedicationsusedfor the treatment of cardiovascular, respiratory,andendocrineproblems. ItisimportanttonotethattheHalalstatusoftheactiveingredientsandexcipientsofaparticulardosage form was based on animal or alcoholsource.Halalstatusisdependentonthenatureoftheproductandhowitwasmade,amongothers.Other aspects such as potential harmfulnessand the hygiene of preparation processes werenot taken into consideration. These aspects arenormally addressed by competent authoritiessuch as the Halal certification body and StateIslamic Religious Department or Council.Competent certifying authorities examine allmaterials and processes used in the productionof the pharmaceuticals. The safety and hygieneaspectsofthemanufacturingprocessneedseriousconsideration as there are reports related toethical issues pertaining to the use of deadmaterials (slaughtering and using of animalsnotbasedonShariahlaw)inproducts(9).SomeIslamic governments have even started askingpharmaceuticalcompaniesaboutthelabellingoftheirproductsandthesourcesoftheiringredients.TheCompetitionCommissionofPakistan(CCP)hasmandatedthatallpharmaceuticalcompaniesthatsupplythemeningitisvaccineuseonlyHalalmaterials(10). In the last decade, awareness of Muslimson the use of Halal medications has improved(11–19). Several local studies on this issue havebeen published (20,21). Most recently,the Department of Standards Malaysia, incollaboration with religious authorities anduniversity researchers, produced a final draftof the Malaysian Standard related to HalalPharmaceuticals, known as MS 2424. ThisMalaysian Standard describes the generalguidelines in the manufacturing and handlingof Halal pharmaceuticals. It serves as a basicrequirement for Halal pharmaceuticals inMalaysia (22). TheMS 2424 can be consideredasastartingpointforthecertificationprocessofpharmaceuticalproducts.However,thestandarddoesnotnecessarilycontainalltherequirementsfor certification. Halal certification may besought by fulfilling the requirements set by thecompetent Islamic authorities in Malaysia. Themanufacturershavetofurnishtheauthoritywith

complete information on their products neededforHalalcertification.Similarly,intheUKandintheUS,pharmaceuticalcompaniesaremandatedbytheirgovernmentstoprovidefullinformationabouttheirproducts(23). When it comes to religiousmatters relatedtomedicines, especiallyHalal-Haram, there is awidedivergenceofopinionwhichcouldbearecipefor controversy.Thus, some truths on theHalalstatusofpharmaceuticalsneedtobehighlighted.Forinstance,majorityofpharmaceuticalproductscontainsomeconstituentsofethanolandanimalderivatives, which cannot be considered Halal.Although products can contain ingredientsderivedfromanimals(exceptnon-halalanimals),these have to be prepared according to ShariahLaw which dictates procedures for slaughteringandpreparinganimals. An example of an ingredient which isnot Halal is dibasic sodium phosphate, whichoriginates from several sources includinganimal bones or bone ash. Likewise, aprotininis obtained frombovine lung, and the animal ismost likelynot slaughteredaccording to Islamicinstructions. Similarly, other compounds suchas beractant, sodium biphospahte and sodiumphosphatedehydrate areof bovineorigin and itis unsure whether the manufacturer complieswithShariahLawduringtheprocessingofthesesubstances.Sincethereisnodefiniteinformationand consensus on thismatter, these substancesarecategorizedasMushbooh. It was a challenge to convince themanufacturers to furnish detailed informationregarding the sources of substances used in theformulation of pharmaceutical products. Asshown in Table 1, some formulations in tabletformwerecategorizedasHaramforthisreason.

Conclusion

This exploratory study provides insightinto the issue of Halal status of cardiovascular,respiratory, and endocrine medications. Ashighlighted earlier, 23.8% of products surveyedwere categorized as Haram, while more thanhalf (57.1%) were evaluated as Musbhooh. ItaddstotheexistingresearchneededtomeettheHalal requirements of the Muslim communityin consuming Halal pharmaceutical productscontainingchemicalsubstances.Astherearefewreferencesonthetopic,thereisaneedforfurtherinvestigation and exploration for alternativeproducts.
