Progesterone and its metabolites disrupt the normal balance of neurotransmitters in the central nervous system. First of all, GABAergic and serotonergic transmissions are affected.
Symptoms and diagnostic criteria for PMS are presented in the table:
Less often are dysmenorrhea, changes in appetite, hot flashes, nausea and a number of other symptoms.
PMS of the most severe course is called premenstrual dysphoric disorder.
Risk factors:
1) PMS in family history.
2) Age. PMS is more often observed in women in the age range of 25-40 years.
3) Stress.
4) Obesity. The results of population studies clearly showed the relationship between the risk of PMS and the body mass index of more than 30.
5) Depression or anxiety disorder in the anamnesis.
Treatment.
In the west, the drugs of the first line are
serotonin reuptake inhibitors (
fluoxetine,
sertraline and others) that restore serotonergic transmission in the central nervous system.
Traditionally, PMS is widely prescribed
combined oral contraceptives. From the point of view of pharmacodynamics, their effectiveness is explained by the suppression of ovulation and, as a consequence, a decrease in the production of progesterone. Nevertheless, the data of randomized clinical trials are ambiguous. Apparently, the most effective in PMS contraceptives based on ethinyl estradiol and drospirenone. The latter is an analogue of the diuretic spironolactone, which causes a number of positive pharmacodynamic effects in PMS (see below).
As an anesthetic, prescribe
nonsteroidal anti-inflammatory drugs (
ibuprofen,
naproxen,
diclofenac and others). In addition, the appointment of vitamin-mineral complexes containing calcium, magnesium and vitamin D.
