Parturition can be synchronized in cattle by inducing or postponing. An intramuscular injection of glucocorticoid and/or Prostaglandin F2a (PGF) induces calving within a few days after the treatment with a high incidence of retention of fetal membrane. A combined administration of a long-acting glucocorticoid and PGF improves the synchrony of partuntion, but does not reduce the incidence of ret...

Pyridine-4-carboxylic acid hydrazide, commercially known as isoniazid (INH), is an antitubercular drug and is now widely used together with rifampicin and streptomycin for the chemotherapy of tuberculosis. Ritodrine hydrochloride (RTH), chemically, 1-(4-hydroxyphenyl)-2-[2-(4-hydroxyphenyl)ethylamino]propanol is a potent tocolytic drug and is a selective β2-adrenoceptor agonist and is used to c...

Spectrophotometric methods are proposed for the determination of drugs containing a phenol group [salbutamol sulphate (SLB), ritodrine hydrochloride (RTD), isoxsuprine hydrochloride (IXP)] and drugs containing an aromatic amine group [dapsone hydrochloride (DAP), sulfamethoxazole (SFM), and sulfadiazine (SFD)] in pharmaceutical dosage forms. The methods are based on coupling of N, N-diethyl-p-p...
