Nheyo dzeFarmacology
Pharmacology ibazi rebhayoloji rinoongorora mishonga nemigumisiro yayo pazvisikwa zvipenyu. Sainzi iyi inosanganisira ruzivo rwezvinobva mishonga, hunhu hwemakemikari, mhedzisiro yebhayoloji, nzira dzekuita, kunyudzwa, kugoverwa, metabolism, uye kubviswa kwemishonga. Munyika yezvekurapa, pharmacology chinhu chakakosha chisingaparadzaniswi nemaitiro ehutano ezuva nezuva nekuti chinobatsira vanachiremba nevashandi vekurapa kupa kurapa kunoshanda uye kwakachengeteka kuvarwere.
1. Nhoroondo Pfupi yeFarmacyology
Kurapa mishonga kwagara kuripo uye kwava neruzivo rwakawanda sezvo ruzivo rwevanhu rwafambira mberi. Kare, vanhu vekare vaishandisa zvirimwa, zvicherwa, nemhuka semishonga. Marudzi ekare akadai seEgypt, China, India, neGreece akanyora kushandiswa kwemishonga yakasiyana-siyana yechisikigo.
Muzana remakore rechi19, pharmacology yakatanga kukura sesainzi yakarongeka zvakanyanya. Kufambira mberi uku kwakakonzerwa zvikuru nekufambira mberi mumakemikari uye physiology. Masayendisiti akadai saFrançois Magendie, Claude Bernard, naRudolf Buchheim vakaita basa rakakosha mukuisa hwaro hwe pharmacology yemazuva ano.
2. Pharmacodynamics uye Pharmacokinetics
Pharmacology yakakamurwa kuita zvikamu zviviri zvikuru, zvinoti pharmacodynamics uye pharmacokinetics.
1. Pharmacodynamics: Uku ndiko kudzidza kuti zvinodhaka zvinokanganisa sei muviri. Pharmacodynamics inotsanangura mashandiro ekushanda kwemishonga pamazinga emamorekuru, tissue, uye nhengo. Maitiro aya anosanganisira kudyidzana pakati pemamorekuru emishonga nemareceptor emasero, izvo zvinozoburitsa mhinduro yemuviri. Semuenzaniso, maenzyme inhibitors akadai seACE inhibitors anoshanda nekudzivisa kushanda kwemaenzymes nekuderedza BP.
2. Pharmacokinetics: Iyi inyaya yekudzidza mashandiro anoita mishonga mumuviri, kusanganisira nzira dzekunyudzwa, kugoverwa, kushandiswa kwemetabolism, uye kubviswa kwayo (ADME). Pharmacokinetics inotibatsira kunzwisisa kuti mhedzisiro yemushonga icharamba kwenguva yakareba sei mumuviri uye kuti tingapa sei mushonga wakakodzera. Semuenzaniso, mishonga inokurumidza kugayiwa nechiropa inogona kuda madhigirii akawanda kana kupiwa kakawanda kupfuura mishonga inogayiwa zvishoma nezvishoma.
3. MaReceptors uye Maitiro Ekushanda Kwemishonga
MaReceptors mapuroteni ari mumuviri anobatana nemishonga uye anotonga mhedzisiro yayo yekurapa. MaReceptors aya anogona kuwanikwa pamusoro pesero kana mukati mesero. Kune mhando dzakasiyana dzemaReceptors, dzinosanganisira:
1. MaG-Protein Coupled Receptors (GPCRs): Mareceptor aya akabatana nemaG-protein ari mu membrane yesero uye anotanga nzira dzakasiyana dzekutumira mameseji mukati mesero. Muenzaniso ndewe adrenergic receptor inopindura ku epinephrine.
2. MaIon Channel Receptors: Aya mareceptor anodzora kufamba kwemaion kuburikidza nemasero. Semuenzaniso, Loratadine inoshanda pa histamine H1 receptor, iyo inokanganisa maion channels.
3. Tyrosine Kinase Receptors: Aya mareceptor anoshanda mukudzora kukura kwemasero uye metabolic signaling. Muenzaniso i insulin receptor.
4. MaReceptor emukati memasero: MaReceptor aya anowanzo kuwanikwa mukati memasero uye anokanganisa kuratidzwa kwemajini. Muenzaniso isteroid hormone receptor.
4. Kunwa Mishonga
Kupinza mushonga muropa inzira inoshandiswa nekushandisa mushonga kubva panzvimbo yaunopinza mushonga. Kune nzira dzakasiyana-siyana dzekupinza mushonga uyu, dzinosanganisira kunwa nemuromo, kuisirwa mutsinga, kuisirwa mutsinga, pasi peganda, kufemereka, kuisirwa mutsinga, nedzimwe nzira. Nzira imwe neimwe ine zvakanakira uye zvisingakwanisike pakupinza mushonga uye kushanda kwawo.
1. Kunwa: Nzira inonyanya kushandiswa nekuda kwekureruka kwayo. Zvisinei, zvinhu zvakaita se pH yemudumbu, kufamba kwemudumbu, uye kuvapo kwechikafu zvinogona kukanganisa kunwa kwemushonga.
2. Mutsinga (IV): Inoisa mushonga zvakananga muropa, zvichiita kuti mushonga utange kushanda nekukurumidza uye kudzora uwandu hwemushonga nemazvo.
3. Mutsinga dzemudumbu (IM) neSubcutaneous (SC): Zvinopa mukana wekuchinjika munguva yekutanga kwechirwere inononoka kupfuura IV asi inokurumidza kupfuura yemuromo.
4. Kufema uye Transdermal: Inonyanya kushandiswa pamishonga inoda kunyudzwa nekukurumidza kuburikidza nemapapu kana ganda.
5. Kuparadzirwa Kwemishonga
Kugoverwa kwemishonga kunotsanangura kuti mushonga unoparadzirwa sei mumuviri wese, kusanganisira kugoverwa kwemishonga kunhengo dzakasiyana. Izvi zvinokonzerwa nezvinhu zvakaita sekuyerera kweropa, kupinda kweropa mumuviri, uye hunhu hwemakemikari emushonga. Huwandu hwekugoverwa kwemishonga iyi ndiyo nzira inowanzo shandiswa kutsanangura kugoverwa kwemishonga mumuviri. Inopa chiratidzo chekuti mushonga wacho unoparadzirwa sei kunhengo dzakasiyana kana uchisara muropa.
6. Kugayiwa Kwemishonga Mumuviri
Metabolism inzira yebiochemical inoshandura mishonga kuita mafomu anoburitswa nyore nyore. Kazhinji metabolism yemishonga inoitika muchiropa kuburikidza nema enzymes akadai se cytochrome P450 (CYP). Metabolism inogona kuwedzera kana kuderedza mashandiro emishonga yemushonga. Semuenzaniso, codeine inogadziriswa kuita morphine, inova ndiyo nzira inoshanda yemushonga. Zvinhu zvemajini, kudyidzana kwemishonga, uye hutano hwemurwere zvinogona kukanganisa metabolism yemushonga.
7. Kubviswa kwemushonga
Kuburitsa mushonga inzira yekubvisa mishonga nemetabolites mumuviri, zvinonyanya kuitwa neitsvo kuburikidza neweti. Pamusoro peitsvo, chiropa, mapapu, ganda, uye nzira yekugaya zvekudya zvine basawo mukuburitsa mushonga. Mwero wekuburitsa mushonga unokanganisa nguva uye simba remhedzisiro yemushonga, zvichiita kuti uve chinhu chakakosha pakugadzira nzira yekurapa.
8. Mishonga yeChepfu
Toxicology inyaya yekudzidza nezvemigumisiro inokuvadza yemakemikari, kusanganisira mishonga. Huturu hunogona kukonzerwa nekunyanyisa kushandisa mishonga, allergy, kusangana nemishonga, kana mimwe migumisiro isingadiwe. Kuongorora kuchengetedzeka kwemishonga kunosanganisira miedzo yakaoma yekiriniki uye yekiriniki kuti ive nechokwadi chekuti mabhenefiti ekurapa anopfuura njodzi dzinogona kuitika.
9. Pharmacogenomics
Pharmacogenomics inyaya yekudzidza kuti kusiyana kwemajini emunhu mumwe nemumwe kunokanganisa sei kupindura kwemishonga. Nekunzwisisa magene emurwere, kurapwa nemishonga kunogona kugadziriswa kuti kuwane mhedzisiro yakanaka pasina njodzi yakawanda yemigumisiro yakaipa. Iyi inzvimbo iri kukura nekukurumidza mu pharmacology, ichipa mukana wekuvandudza kushanda zvakanaka uye kuchengetedzeka kwekurapa.
Mhedziso
Kudzidzira mishonga ibasa guru rine zvinhu zvakasiyana-siyana, kubva pakuwana nekugadzira mishonga kusvika pakupa mishonga uye kuongororwa kwemigumisiro yekurapa, pamwe nekuongorora chepfu. Kunzwisisa zvakadzama zvinhu zvakakosha zvemishonga kwakakosha kuti kuve nechokwadi chekushandiswa kwakachengeteka uye nemazvo kwemishonga mukurapa. Kuburikidza nekutsvaga kunoramba kuripo uye kufambira mberi kwetekinoroji, pharmacology icharamba ichiita basa guru mukusimudzira mushonga nekuvandudza hupenyu hwevanhu.
