Actions and spectrum:
Rituximab’s mechanism and range are simple. It is an antibody with parts from human and mouse sources. One part targets CD20, a protein on B cells from the start. CD20 may help B cells work properly.

Pregnancy/Lactation
Pregnancy: When a woman gets pregnant, a medicine called rituximab can be dangerous. It belongs to pregnancy category D. This drug might go through the mother’s placenta and harm the baby. Therefore, it shouldn’t be taken when expecting.
Lactation: Rituximab can also get into a mother’s breast milk. So, if a woman is breastfeeding, she must not use this medication. It may hurt the baby if taken while nursing.
Pregnancy category:
Pharmacology:
Rituximab works by pinpointing and destroying certain cells in the body. It treats particular kinds of cancer and autoimmune diseases. The medicine targets cells. It causes those specific cells to die. Rituximab is used for treating certain cancers. It also treats autoimmune diseases.
Pharmacodynamics:
Rituximab makes cells die in a few different ways. One is ADCC (antibody-dependent cell-mediated cytotoxicity). Another way is ADP (antibody-dependent phagocytosis). The last way is CDC (complement-mediated cytotoxicity). It works by messing up B cells in the immune system. This stops plasma cells from being made.
Pharmacokinetics:
Absorption
Rituximab achieves a peak of 157 mcg/ml after the first infusion. Then 183 mcg/ml following the second.
Distribution
It has a volume distribution of 3.1 liters.
Metabolism
As rituximab is a monoclonal antibody, it gets metabolized all over the body by proteases.
Elimination and excretion
Elimination primarily happens through the reticuloendothelial system. Antidrug antibodies form immune complexes, then endocytosed via Fcγ-mediated mechanisms to facilitate this. Rituximab’s half-life varies: 22 days for NHL, 32 for CLL, 18 for RA, and 22 for GPA and MPA.
Administration:
Rituximab is only given through IV infusion. Don’t give as bolus or push. For first infusion, start at 50 mg/hr. Raise 50 mg/hr every thirty minutes if no reactions, up to 400 mg/hr max. Later infusions start 100 mg/hr. Increase same way up to 400 mg/hr if tolerated. Young NHL/B-AL patients can increase faster — 0.5 mg/kg/hr more every thirty minutes from 0.5 mg/kg/hr start (max 50 mg/hr), up to 400 mg/hr max with no reactions.

Pronunciation: Rih-TUK-si-mab
Use: Rituximab treats certain cancers. For example, Non-Hodgkin Lymphoma and Chronic Lymphocytic Leukemia. But it also helps autoimmune diseases, like Rheumatoid Arthritis. And Pemphigus Vulgaris too.
