Preferential and selective COX-2 inhibitors.pptxMadhumita Dixit
Cyclo-oxygenase inhibitors -These drugs have three major therapeutic actions
1)Anti-inflammatory action: The decrease in prostaglandin E2 and prostacyclin reduces vasodilatation and, indirectly, oedema. Accumulation of inflammatory cells is not directly reduced.
2) Analgesic effect: Decreased prostaglandin generation means less sensitization of nociceptive nerve endings to inflammatory mediators such as Bradykinin and 5-hydroxytryptamine. Relief of headache is probably a result of decreased prostaglandin-mediated vasodilatation.
3) Antipyretic effect: Interleukin-1 releases prostaglandins in the central nervous system, where they elevate the hypothalamic set point for temperature control, thus causing fever, NSAIDs prevent this.
Fexofenadine is sold under the brand name Allegra.
It is a selective peripheral H1 blocker. It is classified as a second-generation antihistamine because it is less able to pass the blood–brain barrier and causes lesser sedation, as compared to first-generation antihistamines.
It is on the World Health Organization's List of Essential Medicines. Fexofenadine has been manufactured in generic form since 2011.
It is an alkaloid obtained from the plant Colchicum Autumnale.
It is neither analgesic, nor anti-inflammatory, but specifically suppresses gouty inflammation.
It was first described for treatment of rheumatism
and swelling in the Ebers Papyrus(Egyptian medical text) in 1500 BC.
CLASSIFICATION OF H1 ANTIHISTAMINICS-
FIRST GENERATION ANTIHISTAMINICS-
1)HIGHLY SEDATIVE-DIPHENHYDRAMINE,DIMENHYDRINATE,PROMETHAZINE,HYDROXYZINE 2)MODERATELY SEDATIVE- PHENARIMINE,CYPROHEPTADINE, MECLIZINE,CINNARIZINE
3)MILD SEDATIVE-CHLORPHENIRAMINE,DEXCHLORPHENIRAMINE
TRIPROLIDINE,CLEMASTINE
SECOND GENERATION ANTIHISTAMINICS-FEXOFENADINE,
LORATADINE,DESLORATADINE,CETIRIZINE,LEVOCETIRIZINE,
AZELASTINE,MIZOLASTINE,EBASTINE,RUPATADINE. Mechanism of action of 2nd generation antihistaminics-
These drugs competitively antagonize actions of
histamine at the H1 receptors.
Pharmacological actions-
Antagonism of histamine-The H1 antagonists effectively block histamine induced bronchoconstriction, contraction of intestinal and other smooth muscle and triple response especially wheal, flare and itch. Constriction of larger blood vessel by histamine is also antagonized.
2) Antiallergic actions-Many manifestations of immediate hypersensitivity (type I reactions)are suppressed. Urticaria, itching and angioedema are well controlled.3) CNS action-The older antihistamines produce variable degree of CNS depression.But in case of 2nd gen antihistaminics there is less CNS depressant property as these cross BBB to significantly lesser extent.
4) Anticholinergic action- many H1 blockers
in addition antagonize muscarinic actions of ACh. BUT IN 2ND gen histaminics there is Higher H1 selectivitiy : no anticholinergic side effects
Selective alpha1 blockers are Prazosin, Terazosin, Doxazosin, Tamsulosin and Silodosin majorly used to treat BPH, also hypertension, PTSD, Raynaud's phenomenon, CHF
Congestive Heart failure is caused by low cardiac output and high sympathetic discharge. Diuretics reduce preload, ACE inhibitors lower afterload, beta blockers reduce sympathetic activity, and digitalis has inotropic effects. Newer medications target vasodilation and myosin activation to improve heart efficiency while lowering energy requirements. Combination therapy, following an assessment of cardiac function and volume status, is the most effective strategy to heart failure care.

Storyboard on Skin- Innovative Learning (M-pharm) 2nd sem. (Cosmetics)MuskanShingari
Skin is the largest organ of the human body, serving crucial functions that include protection, sensation, regulation, and synthesis. Structurally, it consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous layer).
1. **Epidermis**: The outermost layer primarily composed of epithelial cells called keratinocytes. It provides a protective barrier against environmental factors, pathogens, and UV radiation.
2. **Dermis**: Located beneath the epidermis, the dermis contains connective tissue, blood vessels, hair follicles, and sweat glands. It plays a vital role in supporting and nourishing the epidermis, regulating body temperature, and housing sensory receptors for touch, pressure, temperature, and pain.
3. **Hypodermis**: Also known as the subcutaneous layer, it consists of fat and connective tissue that anchors the skin to underlying structures like muscles and bones. It provides insulation, cushioning, and energy storage.
Skin performs essential functions such as regulating body temperature through sweat production and blood flow control, synthesizing vitamin D when exposed to sunlight, and serving as a sensory interface with the external environment.
Maintaining skin health is crucial for overall well-being, involving proper hygiene, hydration, protection from sun exposure, and avoiding harmful substances. Skin conditions and diseases range from minor irritations to chronic disorders, emphasizing the importance of regular care and medical attention when needed.

2. Introduction-
Allopurinol, an Anti-gout
drug is used as Uric acid
synthesis inhibitor.
It is on the World Health
Organization's List of
Essential Medicines.
3.
4. Mechanism of action-
Hypoxanthine
Xanthine urate
Xanthine oxidase
Allopurinol
Oxypurinol
-
Allopurinol acts on purine catabolism, and thus reduces
production of urate without disrupting the biosynthesis
of vital purines.
5. • Allopurinol also is a substrate of Xanthine
oxidase
• It is a competitive inhibitor of Xanthine
oxidase at low concentrations and non-
Competitive inhibitor of Xanthine oxidase at
higher concentrations.
• Oxypurinol is Non-competitive inhibitor of
Xanthine Oxidase.
6. Uses-
Gout treatment (chronic urate-lowering therapy)also facilitates
dissolution of Tophi and inhibits development or progression
of Chronic Gouty Arthritis.
Nephrolithiasis (prevention of recurrent calcium or uric acid stones)
Tumor lysis syndrome prevention (To prevent hyperuricemia in
patients with hematological malignancies about to undergo
chemotherapy)
Inflammatory Bowel Disease
IN CHILDREN-
Lesch-Nyhan syndrome (Hyperuricemia associated
with errors of purine metabolism)
Glycogen storage diseases(recurrent calcium oxalate renal stones)
8. Colchicine + Allopurinol
The incidence of acute attacks of gouty arthritis
may increase during the early months of
allopurinol therapy as a consequence of
mobilization of tissue stores of uric acid.
Coadministration of colchicine helps suppress
such acute attacks. After reduction of excess
tissue stores of uric acid, the incidence of acute
attacks decreases and colchicine can be
discontinued.
9. Adverse effects-
The most common adverse effects are
hypersensitivity reactions(pruritic,
erythematous, or maculopapular eruption)
Rarely, Toxic Epidermal Necrolysis or Stevens-
Johnson syndrome occurs, which can be fatal.
1-10%-Nausea, vomiting, acute gout, Renal
insufficiency
10. Pregnancy-Category ‘C’
Lactation-Excreted in breastmilk, caution must be
exercised when administering Allopurinol to
breastfeeding women.
Routes of administration-
Oral (tablet)
intravenous
Pregnancy and Lactation-
11. Drug interactions-
Allopurinol +Probenecid-
Allopurinol increases the t1/2 of probenecid and
enhances its uricosuric effect, while probenecid
increases the clearance of Oxypurinol, thereby
increasing dose requirements of allopurinol.
Allopurinol + Mercaptopurine/Azathioprine-
Allopurinol inhibits enzymatic inactivation of
mercaptopurine and azathioprine by xanthine
oxidase. Thus, when used together dosage of the
antineoplastic agent must be reduced by 25–33%
This is of importance when treating gout in the
transplant recipient.
12. Allopurinol + Cyto-toxic agents
The risk of bone marrow suppression also is
increased when allopurinol is administered with
cytotoxic agents that are not metabolized by
xanthine oxidase, particularly cyclophosphamide.
Allopurinol + Warfarin-
It interferes with the hepatic inactivation of
Warfarin .Increased monitoring of prothrombin
activity is recommended in patients receiving
both medications.
13. Summary-
Allopurinol a uric acid synthesis inhibitor works
by inhibition of Xanthine Oxidase.
It is used for Chronic Gout treatment
It has a primary metabolite-Oxypurinol
