Histone deacetylase inhibitors


A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.

Histone deacetylase (HDAC) inhibitors are a group of agents that inhibit the histone deactylase enzymes. During gene expression DNA coils and uncoils around histones. Histone acetylases, acetylate the lysine residues in core histones and histone deactylases remove the acetyl groups from the lysine residues. These actions are important in the regulation of gene expression.


Histone deacetylase inhibitors prevent the deactylation, affect gene expression and causes apoptosis of tumor cells. Histone deacetylase inhibitors are used to treat cutaneous T-cell lymphoma.

  • Cutaneous T-cell Lymphoma

Hormone replacement therapy


Hormone replacement therapy involves supplementing female hormones for the relief of symptoms resulting from an end in ovarian function, either following surgical removal of the ovaries or after natural menopause.


Estrogens can be prescribed alone or in combination with progestins. A combination of estrogen and progestin is preferred if the woman has her uterus as estrogen alone can over stimulate the endometrium causing uterine bleeding. Hormone replacement therapy is effective in controlling symptoms such as hot flashes, vaginal dryness, psychological well-being and in preventing osteoporosis.

H2 antagonists


A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.

H2 antagonists competitively inhibits histamine at the H2 receptors and leads to a reduction in secretion of gastric acid.


Histamine stimulates the secretion of gastric acid by action on H2 receptors, which are found in the parietal cells of the gastric mucosa.


H2 antagonists are used to treat gastroesophageal reflux disease (GERD), gastrointestinal ulcers and other gastrointestinal hypersecretory conditions.

Heparins


A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.

Heparin is an injectable anticoagulant that activates antithrombin III, which inhibits thrombin and factor Xa, factors necessary in the final stages of blood clotting cascade.


There are two types of heparins: high molecular weight heparins and low molecular weight heparins.


High molecular weight heparins require daily blood monitoring to check the aPTT. Low molecular weight heparins give a better anticoagulant response and do not need daily blood monitoring.


Heparin is used to treat or prevent clots in conditions where there is a high risk of clot formation and thromboembolism, such as in atrial fibrillation, myocardial infarction, deep vein thrombosis, knee and hip surgery and so on.

HER2 inhibitors


A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.

Human epidermal growth factor receptor (HER2) inhibitors are either tyrosine kinase inhibitors or monoclonal antibodies that slow down or stop cell growth.


Human epidermal growth factor receptors are transmembrane receptors; they have an extracellular binding component, a transmembrane component and an intracellular tyrosine kinase component. Some breast cancers have an over-expression of HER2 resulting in increased cell growth and spread of cancer cells.


Tyrosine kinase inhibitors bind to the tyrosine kinase domain in the HER2 and stops activation of the signaling pathway. Monoclonal antibodies bind to the extracellular component of the HER2, prevent the actual substrates from binding to the receptors and stop the receptor activation.


HER2 inhibitors are used in the treatment of breast cancer.

  • Breast Cancer, Adjuvant
  • Breast Cancer, Metastatic
  • Esophageal Carcinoma
  • Gastric Cancer

Hematopoietic stem cell mobilizer


A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.

Hematopoietic stem cell mobilizer binds to the CXCR4 chemokine receptor and inhibits the binding of its ligand, stromal cell-derived factor-1-alpha (SDF-1-alpha). This leads to mobilization of hematopoietic stem cells to the peripheral blood.


The hematopoietic stem cells (CD34+ cells) are collected from the peripheral blood and used for autologous transplantation in patients with non-Hodgkins

Medical conditions associated with hematopoietic stem cell mobilizer:

  • Multiple Myeloma
  • Non-Hodgkin's Lymphoma

H. pylori eradication agents


A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.

Agents used in treatment of Helicobacter Pylori are medicines used for stomach acid inhibition, combined with antibacterial agents. Treatment is for one week with a proton pump inhibitor or an antacid (or antisecretory agents), and two appropriate antibacterial agents. This one week triple therapy does give a good eradication rate.

Hydantoin anticonvulsants


A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.

Hydantoin anticonvulsants are structurally related to barbiturates. They have an allantoin heterocyclic base. Hydantoins slow the synaptic transmission by blocking sodium channels from recovering from the inactivated state, and inhibits neurons from firing. This stops the repeated excitation of cells that results in seizures.


Hydantoin anticonvulsants are used to treat a wide range of seizures types.

Hormones


Hormone is a chemical substance that is produced in one part of the body (by an endocrine gland) and is carried in the blood to other distant organs or tissues where it acts to modify their structure or function. Some cells release hormones that induce a response in the neighboring cells (paracrine function), or sometimes the hormones can act on the cells they are released from (autocrine function).


For a cell to respond to a particular hormone it needs to have specific receptors for that hormone, and once the hormone binds to the receptor specific chemical pathways are activated that lead to a response.


Examples of hormones are corticosteroids (from the adrenal cortex), growth hormone (from the pituitary gland) and androgens (from the testes).
