Yaz, a combination oral contraceptive, consists of drospirenone and ethinyl estradiol. It is primarily used to prevent pregnancy and manage conditions related to hormonal imbalances, such as acne and premenstrual dysphoric disorder (PMDD). Drospirenone, a progestin, works together with ethinyl estradiol, an estrogen, to prevent ovulation and cause changes in the cervical and uterine lining, making it harder for sperm to reach the uterus and for a fertilized egg to attach to the uterus.

Zolmitriptan functions primarily by activating serotonin receptors in the brain, which causes vasoconstriction of the cranial blood vessels. This action helps alleviate the migraine’s head pain and associated symptoms. Zomig has a fast onset of action, making it particularly useful for those who experience sudden, debilitating migraines, and its effects can last up to 24 hours.

Acyclovir within Zovirax Ointment is a synthetic nucleoside analogue that specifically targets and disrupts viral replication processes. When applied to affected areas, the ointment obstructs the action of viral DNA polymerase, curtailing viral multiplication. This targeted approach helps control and alleviate herpes symptoms directly where they occur.
