0:00.0 | Hey all, welcome back to the Real Life Pharmacology podcast. I am your host, Eric Christensen. |
0:05.8 | And on this episode, I'm going to cover medroxy progesterone acetate, sometimes referred to as |
0:13.6 | Deppop Provera, as brand name, or DMPA for an abbreviation there as well. |
0:21.6 | So I'm going to specifically kind of stick to the injection here in this episode and the one |
0:29.3 | obviously specifically for contraceptive purposes. |
0:34.5 | So this drug is a progestin-only contraceptive method. It is injection. I mentioned that. |
0:45.0 | And this injection is given every three months. And that certainly can be advantageous for some patients that really aren't very good at remembering to take medications, |
1:00.8 | or they just don't want to worry about it and don't want the hassle of taking a once-daily contraceptive. |

1:49.7 | the risk for pregnancy is extremely, extremely low. |
1:55.1 | Adverse effect profile? |
1:58.6 | Well, first, let's cover mechanism of action. |
2:05.9 | So how does this prevent pregnancy? |
2:16.2 | So the drug inhibits gonadotropin release from the pituitary. And so if you remember that, by blocking that, that can actually, those gonadotropins are |
2:20.6 | necessary for ovulation and follicular maturation, things of that nature. |
2:27.5 | And so by blocking that release of those gonadotropins, what you ultimately do is prevent |
2:33.4 | ovulation, which is necessary, |
