Penicillin was discovered by Alexander Fleming in 1928 but did not become widely available until the 1940s. The penicillins are closely related compounds comprising a β-lactam ring, a five-membered thiozolidine ring, and a side chain. The ring structures are essential for antibacterial activity, and the side chain determines the spectrum and pharmacological properties. Most penicillins […]

Explore the major classes of HIV antiretroviral drugs, including their mechanisms of action in targeting different stages of the viral life cycle. This video also highlights common side effects, clinical uses, and the role of combination therapy in effective HIV management.

Mycophenalate is used in lupus nephritis (first line), diffuse SS but also indicated for the prophylaxis of organ rejection in patients undergoing allogeneic renal, hepatic, or cardiac transplants. In transplant patients it should be used with cyclosporine/tacrolimus and corticosteroids. Mycophenolate has a preferential inhibition of IMPDH II the rate limiting step in the de novo […]

Explore the role of Interleukin-1 (IL-1) in immune responses, including its effects on inflammation, fever, and cytokine signaling. This video also covers the pharmacology of IL-1 antagonists, detailing their mechanisms of action and clinical applications in inflammatory diseases.

Tofacitinib is an oral agent taken twice daily used to treat many rheumatological conditions mainly RA. Tofacitinib inhibits Janus kinase (JAK) signalling. Immune cells such as macrophages, monocytes and T cells play a key role in the pathophysiology of RA. They contain receptors on their surface which rely on the JAK. JAK initiates a cascade […]

Learn about sulfasalazine, a disease-modifying antirheumatic drug (DMARD) used to treat inflammatory conditions like rheumatoid arthritis and IBD. This video explains its pharmacology, mechanism of action, metabolism, and potential side effects including gastrointestinal upset and hypersensitivity reactions.

Leflunomide is an immunosuppressant used to treat RA and psoriatic arthritis and Multiple sclerosis. Leflunomide is a prodrug that is rapidly and almost completely metabolized following oral administration to its pharmacologically active metabolite, A77 1726 or teriflunomide. The mechanism of action of leflunomide has not been fully determined, but appears to primarily Inhibit the mitochondrial […]

Learn about cyclophosphamide, a powerful alkylating agent used in cancer treatment and autoimmune diseases. This video explains its pharmacology, DNA-crosslinking mechanism of action, and potential adverse effects such as myelosuppression, hemorrhagic cystitis, and infertility.

Calcineurin inhibitors such as tacrolimus and cyclosporine are immunosuppressants. They are used mainly to prevent organ transplant rejection in combination with mycophenolate and steroids as well used in severe atopic dermatitis. They are not really used as much for rheumatologic conditions any more, possibly for lupus nephritis. Calcineurin inhibitors are also used for the treatment […]

Explore azathioprine, an immunosuppressive drug used in autoimmune diseases and organ transplantation. This video covers its pharmacology, mechanism of action in inhibiting purine synthesis, and common side effects including bone marrow suppression and gastrointestinal symptoms.

Explore the mechanisms of action of key chemotherapy agents, including alkylating agents, antimetabolites, topoisomerase inhibitors, and antimitotic drugs. This video provides a concise pharmacology breakdown to support understanding of cancer treatment strategies.

Learn about the acute complications of chemotherapy, including common side effects and serious adverse reactions. This video highlights mechanisms, clinical presentations, and management strategies to improve patient care during cancer treatment.

Explore the pharmacology of Nonsteroidal Anti-Inflammatory Drugs (NSAIDs), including their mechanisms of action, therapeutic uses, and common side effects. This video highlights how NSAIDs reduce inflammation, pain, and fever while addressing potential risks and contraindications.
