Q

Diazepam

A

A short term anti anxiety and insomnia drug. used in alcohol withdrawal. Works by binding to the benzodiazepine receptors which mediates sleep and affects muscle relaxation. Alongside this it is thought to be coupled with the GABA receptors resulting in increased effects of GABA. This results in the opening of chloride channels which hyperpolarses the cells and prevents further excitation of the cell.

Q

Diclofenac

A

NSAID works by inhibiting COX 1 and COX 2 and leukocyte migration. Reduced prostaglandins results in analgesic effects. Also has antipyretic effects due to dissipation of heat through peripheral dilation of blood vessels.

A

1st line Treatment of Hep B by inhibiting all three activities of the HBV polymerase. 1. Base priming 2. reversed transcription of the negative strand in RNA 3. synthesis of the positive strand DNA.

Q

Lamivudine

A

used in prophylaxis of Hep B. Used when the virus is inactive but there is increased risk of activation eg high dose immunosuppressant. Once activated it works by being incorporated into the growing viral DNA by reverse transcriptase. This causes early chain termination and stops viral replication.

A

Part of Harvoni used as second line Hep C treatment. It is a replication inhibitor of Hep C virus protein NS5A which is necessary for both RNA replication and vision assembly

Q

Mycophenolate mofetil

A

used for prophylactic organ rejection. Works by inhibiting T and B cell proliferation and inhibits B cell antibody production

20
Q

Nadalol

A

Acts on B1 receptors inhibiting the binding of NA. This results in decreases heart contractility, decreased cardiac output and decreasing blood pressure. It also acts on the juxtaglomerular B2 receptors which inhibits the production of renin therefore inhibiting Ang 11 and renin production. This results in vasodilation and excretion of water.

21
Q

Ombitasvir

A

Part of the Viekeira pak used for the treatment of chronic Hep C. A Direct acting antiviral that inhibits the replication of the HCV protein NS5A which is used for RNA replication

22
Q

Paracetamol

A

Cox 1 and Cox 2 enzyme inhibitor which results in inhibiting prostaglandin production. Works on the CNS and not on the peripheral cells it increases pain tolerance having analgesic effects.

23
Q

Paritaprevir

A

Part of the Viekeira Pak used for the treatment of Hep C. It is a direct acting antiviral and is an protease inhibitor which cleaves the HCV polyprotein

24
Q

Pravastatin

A

It is a HMG- COA inhibitor which is the rate limiting step to cholesterol synthesis in the liver. It also increases the LDL receptors on the hepatocyte membrane which increases the re-uptake of LDL from the blood to be metabolised in the liver.

25
Q

Propranolol

A

Non cardio-selective beta blocker which competes at the Beta receptor binding sites resulting in decrease Heart rate, decreased contractility of the heart and decreased Blood Pressure. Secondary treatment for ascites

26
Q

Ribavirin

A

Used for Chronic Hepatitis C treatment. It exact mechanism of action is unknown but it is thought to prevent and inhibit the synthesis and replication of HCV.

27
Q

Rifaximin

A

used for treating hepatic encephalopathy. It is not absorbed in the gastro-intestinal tract. Works by inhibiting RNA synthesis of the bacteria.

28
Q

Sofosbuvir

A

Part of the Harvoni treatment of Hep C. It is a direct acting antiviral and is metabolised intracellularly into its active form. It is an inhibitor of the HCV NS5B RNA- dependent RNA polymerase which is essential for viral replication.

29
Q

Tacrolimus

A

Calcineurin inihbitor. It binds to FK-protein which inhibits Calcineurin which inhibits B-Cell activation.

30
Q

Terlipressin

A

An analogue of vasopressin. It binds to V1 receptors in vascular smooth muscle which results in vasoconstriction which decreases portal pressure and decreases blood flow. Used for ascites.

31
Q

Sirolimus

A

Works similarly to tacrolimus but instead works by interfering with lymphocytes through binding of mTOR

32

34
Q

First Line drug therapy for liver transplant

A

Caliceneurin inhibitor - tacrolimus
Steroid - prednisone
Induction agents - basiliximab
Prophylactic meds - antiviral - acyclovir or antibiotics - cefuroxime or co-tromizole

35
