Q

What are Glucagon-like polypeptide-1 (GLP-1) receptor agonists?

A

Q

What is the Mechanism of Actions of -Statins

A

Reversible competitive inhibitors of 3-hydroxy-3methylglutaryl-coenzyme A (HMG-CoA) reductase, the rate-limiting enzyme in cholesterol synthesis.
This increases synthesis and reduces degradation of LDL receptors; therefore more LDL receptors on surface of hepatocytes=increased removal of LDL from blood

Q

What is the MOA of the drug class PCSK9 Inhibitors (Proprotein convertase subtilisin/kexin type 9)?

A

PCSK9 is a protein that binds to the LDL receptor, and reduces the LDL receptor density. This increases circulating LDL.

PCSK9 inhibitors are human monoclonal antibodies that block this process, increase LDL receptors and decrease circulating LDL.

What is the MOA of Combination Oral Contraception:

A

Estrogen: inhibition of FSH release leads to inhibition of the development of dominant follicle, and thus inhibition of ovulation.

It stabilizes endometrium to improve bleeding patterns (for reduced adverse effects).

Progestin: decreases tubal motility-i.e. fimbriae do not wrap around the ovaries, increases cervical mucous viscosity, thins or prevents endometrium formation, and inhibits ovulation through negative feedback.

218
Q

219
Q

221
Q

Functions by increasing progestin levels which thickening cervical mucus to prevent sperm from reaching an egg, prevents building the uterine lining, keeping it thin which make implantation less likely, and inhibiting ovulation by preventing an egg from fully developing

Increasing your progestin levels causing negative inhibition of GnRH which keeps FSH and LH low, preventing follicle proliferation by ensuring no estradiol production.

(Potentially less consistent effect on ovulation than progestin)
