Mycobacteria

Tuberculosis - M. tuberculosis


Leprosy - M. leprae


Atypical mycobacteria infections - M. avium

Tx for TB

Isoniazid, rifampin, pyrazinamide combination해서 사용한다 (셋다 간독성의 문제점이 있다)

Isoniazid

-inhibition of mycolic acid synthesis;


-peripheral neuritis (말초성 신경염)+ pyridoxine 결핍의 부작용..../hypersensitivity


-따라서 pyridoxine을 보충해줘야 합니다.


-inactivated by acetylation.

Rifampin

inhibition of RNAP; hypersensitivity의 부작용.



-Red color in urine, tears.


-liver toxicity


-induction of hepatic microsomal enz --> leads to DDI



트리플 R.

Antifungals (Systemic Use) - Amphotericin B

-pore 형성한다. macromolecule 입니다.


-Hydrophilic & Hydrophobic 한 부분을 갖고 있습니다.


-부작용 = renal impairment.

Antifungals (Systemic Use) - Azole

MOA: inhibition of fungal cytochrome P450 → reduction of ergosterol synthesis;



ADR = due to human CYP450 interaction.


a. Ketoconazole: 처음으로 만들어진 azole계통. 너무 강하므로 oral x / topical O. 간독성.


b. Itraconazole: most potent antifungal activity; active on aspergillus. IV formulation is possible. Strong drug interaction (CYP3A4)


c. Fluconazole: 뇌 감염이 있을 때 (good CSF penetration)


d. Voriconazole, Posaconazole: 항암요법으로 면역력이 떨어져 있는 환자에게 예방/치료의 목적으로 모두 사용. Voriconazole의 특징은 CYP2C19에 의해 대사. Posaconazole은 CYP3A4에 의한 대사 기억할 것!!


Antifungals (Systemic Use) - Flucytosine

FC taken up into fungal cells by cytosine permease. Intracellular metabolism to 5FU.



inhibit DNA, RNA synthesis (사람 세포에서는 active metabolite로 전환되지 않음)

Antifungals (Mucocutaneous Infection) - Terbinafine

–inhibit squalene epoxidase → ergosterol synthesis is inhibited, squalene accumulated (fungicidal); no effect on CYP450 system.

Antifungals (Topical) - Nystatin/Ciclopirox


전신에는 사용하지 않고 topical로만 사용한다.


토O피컬 - 동그라니(Nysta)까 ciclopirox.




cf) nystatin binds to ergosterol.

Respiratory virus infection (eg. Influenza)

a. Influenza A virus M2 Blocker = Amantadine, RiMantadine. Rimantadine의 효과가 더 크다.


rhymes with M!


b. Neuraminidase Inhibitor = Zanamivir, Oseltamivir (viral clumping 유도; sialic acid 분해 억제);


잘라(Zana)낸다


c. Ribavirin: guanosine anagloue. inhibit wide target of DNA & RNA virus. (구라 Gu-RibA)



Respiratory 니깐 Riba


Hepatic viral infection

a. interferon


b. acyclic nucleoside analogue


-Adefovir: adenosine analogue


-Lamivudine: cytosine analogue. Used for HBV as well as HIV. (큰일남. Cy-Lami)



(hepa는 Adefovir로 치료하면 Lam(낫)는다))

For Herpes (HSV, VZV) & CMV infection

a. Acyclic nucleoside analogue.


Acyclovir (acyclic guanosine): 3단계의 phosphorylation을 필요로 한다 (by virus TK);


Ganciclovir - acyclovir의 유도체 (CMV 효과 100배, ADR - myelosuppression; (간보다가 망함)


Cidofovir - requires two phosphorylation



b. Foscarnet: no need for phosphorylation; ADR = nephrotoxicity


(포스가 있는대신 독성이 있다)


Antiretroviral.



HAART (highly active antiretroviral therapy) = three/four drugs taken in combo

a. NRTI: must be phosphorylated by intracellular kinase into their active triphosphated forms


-Zidovudine = AZT: thymidine analogue/ ADR = myelosuppression (Zola 놀다 망함)


-Didanosine: deoxyadenosine 형태/zidovudine 내성균


-Abacavir: guanosine analogue. 아빠 구해줘요.


(지단. Zi-Di-Aba)


+ Tenofovir (oral adenosine analogue)


b. NNRTI = allosteric 한 작용; CYP에 대사 (cf. NRTI는 CYP에 의해 대사 x); HIV1 specific


Efavirenz (에파비렌즈), Nevirapine (네피라핀)


아플(Efa) 때(Nevirapine)



c. PI (protease inhibitor)


Squinavir, Ritonavir (boosting 효과가 있다. ritnonavir --> 다른 약품의 효과 높힘. Strong CYP3A inhibition), Indinavir



프로(protease)의 조건- Indefinitely (Indinavir) 다시 (Ri) 스퀏 (Squinavir)



d. fusion and entry inhibitor


e. Integrase Inhibitor


(d, e 넘어감)


Combination Therapy

Trizivir = abacavir + zidovudine + lamivudine


세가기 뭔지 알지 (A L Z)?
