<strong>Review</strong> <strong>of</strong> <strong>Pharmacology</strong><br />

Immunomodulators<br />

(c) Cytarabine – Inhibits DNA synthesis in S-phase.<br />

(d) Cycloserine – Inhibits bacterial cell wall synthesis.<br />

51. Ans. (a) Given orally as too toxic to intravenous (Ref: KDT 6/e p839-840 )<br />

52. Ans. (b) Hypotension (Ref: KDT 6/e p840)<br />

53. Ans. (a) IgG 1<br />

chimeric monoclonal antibody against TNF (Ref: KDT 6/e p205)<br />

54. Ans. (a) Mepolizumb (Ref: www.wikipedia.org)<br />

55. Ans. (b) Omalizumab (Ref: KDT 6/e p226)<br />

56. Ans. (a) TNF alpha (Ref: KDT 6/e p203)<br />

57. Ans. (c) T-Cell proliferation (Ref: KDT 6/e p837)<br />

58. Ans. (b) Adalimumab (Ref: Katzung 11/e p633)<br />

59. Ans. (b) Ibritumomab (Ref: Katzung 11/e p978)<br />

60. Ans. (a) Ifosfamide (Ref: KDT 6/e p633-634)<br />

61. Ans. (d) Rifampicin (Ref KDT 6/e p840, www.medscape.com/druginfo)<br />

Erythromycin, itraconazol and danazol inhibit the metabolism <strong>of</strong> tacrolimus and thus increase the plasma concentration<br />

whereas rifampicin is an enzyme inducer and decrease its plasma level.<br />

62. Ans. (a) Diabetic retinopathy (Ref: Katzung 11//977; Harrison 17/e p512)<br />

Bevacizumab is a monoclonal antibody against VEGF and is used as an anti-angiogenic drug. It is mainly used for colorectal carcinoma<br />

and is used <strong>of</strong>f-label by intravitreal injection to slow progression <strong>of</strong> neovascular macular degeneration.<br />

63. Ans. (a) Direct antiviral activity (Ref Katzung 11/e p1053 )<br />

64. Ans. (c) Cyclosporine (Ref: KDT 6/e p838)<br />

Cyclosporine inhibits helper T cells (CD4) cells by inhibiting the transcription <strong>of</strong> IL-2 (via calcineurin inihibition).<br />

Answers <strong>of</strong> recent Questions asked by National Board<br />

1. Ans (c) Mycophenolate m<strong>of</strong>etil (Ref. KDT 7th/883)<br />

2. Ans (c) Omalizumab (Ref. KDT 7th/231)<br />

3. Ans (a) Acts on VEGF (Ref. KDT 7th/871)<br />

4. Ans (b) Cyclosporine (Ref: KDT 7th/878)<br />

5. Ans. (a) CD 25 (Ref: KDT 7th/884)<br />

6. Ans. (a) Monoclonal antibody against VEGF (Ref: KDT 7th/871)<br />

7. Ans. (a) CD 20 (Ref: KDT 7th/872)<br />

8. Ans. (c) It selectively affects differentiation <strong>of</strong> T cells (Ref: KDT 7th/863-864)<br />

9. Ans. (a) HIV related neuropathy (Ref: KDT 7th/786)<br />

10. Ans. (d) Abciximab (Ref: KDT 7th/631, 883-884)<br />

11. Ans. (d) Cyclosporine A (Ref: KDT 7th/880-881)<br />

12. Ans. (b) Tazarotene (Ref: KDT 7th/891)<br />

13. Ans. (b) Levamisol (Ref: KDT 7th/852)<br />

14. Ans. (b) Levamisole (Ref: KDT 7th/812)<br />

15. Ans. (a) CD4 cells (Ref: KDT 7th/838-39)<br />
