Therapeutic Action of Different Classes of Drugs
Therapeutic action refers to the specific ways in which drugs interact with biological molecules and systems to alleviate or treat various diseases and medical conditions.
Class 1: Antibiotics
Antibiotics are drugs that target and kill harmful microorganisms, such as bacteria, viruses, and fungi. They work by interfering with the microbial's cellular processes, such as protein synthesis, DNA replication, and cell division. Examples include penicillin, erythromycin, and tetracycline.
Class 2: Hormones
Hormones are chemical messengers produced by endocrine glands and transported to target cells in the body. They influence various physiological processes, including growth, development, metabolism, and reproduction. Examples include estrogen, testosterone, and cortisol.
Class 3: Chemotherapy Drugs
Chemotherapy drugs are designed to target and kill cancer cells. They work by either inhibiting cell division, disrupting DNA replication, or interfering with cell signaling pathways. Examples include chemotherapy drugs like paclitaxel, doxorubicin, and cisplatin.
Class 4: Anabolic-Androgenic Steroids (AAS)
Anabolic-androgenic steroids (AAS) are synthetic substances that mimic the effects of testosterone in the body. They are used to treat conditions such as acne, hair loss, and muscle hypertrophy in athletes. Examples include testosterone, nandrolone, and prednisone.
Class 5: Antidepressants
Antidepressants are drugs that treat depression and other mental health disorders by increasing the levels of serotonin and norepinephrine neurotransmitters in the brain. Examples include serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), and selective serotonin reuptake inhibitors (SSRIs).
Class 6: Antipsychotics
Antipsychotics are drugs used to treat schizophrenia and other psychotic disorders. They work by blocking neurotransmitter activity in the brain, which can help reduce psychotic symptoms such as delusions, hallucinations, and agitation. Examples include chlorpromazine, haloperidine, and butyrophenazine.
Therapeutic Action Across Classes
Therapeutic action across different classes of drugs can often occur synergistically, meaning that the combined effects can be greater than the sum of their individual effects. For example, antibiotics can work synergistically with hormones to treat sexually transmitted infections, and chemotherapy drugs can work synergistically with radiotherapy to kill cancer cells
